- 简单配置
自定义Realm
// 自定义
public class UserRealm extends AuthorizingRealm {
// 授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行了授权=》doGetAuthorizationInfo");
return null;
}
// 认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
System.out.println("执行了认证=》doGetAuthenticationInfo");
return null;
}
}
ShiroConfig配置类
@Configuration
public class ShiroConfig {
// 创建realm类，需要自定义类
@Bean
public UserRealm userRealm(){
return new UserRealm();
}
// DefaultWebSecurityManager
@Bean
public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
// 关联UserRealm
securityManager.setRealm(userRealm);
return securityManager;
}
// ShiroFilterFactoryBean
@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("getDefaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager){
ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
// 设置安全管理器
bean.setSecurityManager(defaultWebSecurityManager);
return bean;
}
}
- 设置几个页面
add.html
DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Titletitle>
head>
<body>
<h1>addh1>
body>
html>
del.html
DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Titletitle>
head>
<body>
<h1>delh1>
body>
html>
index.html
DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Titletitle>
head>
<body>
<h1>首页h1>
<p th:text="${msg}">p>
<a th:href="@{/user/add}">adda> <br>
<a th:href="@{/user/del}">dela>
body>
html>
- 配置Controller
@Controller
public class MyController {
@RequestMapping("/")
public String toIndex(Model model){
model.addAttribute("msg", "Hello World");
return "index";
}
@RequestMapping("/user/add")
public String add(){
return "user/add";
}
@RequestMapping("/user/del")
public String del(){
return "user/del";
}
}
这样就在启动项目后，就可以看到，现在是可以自由切换，下面进行更深的配置
2、Shiro实现登陆拦截
- 新增登录页面
DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Titletitle>
head>
<body>
<h1>登录页面h1>
<form action="">
<p>用户名：<input type="text" name="username"> p><br>
<p>密码：<input type="password" name="password"> p><br>
<p><input type="submit"> p>
form>
body>
html>
@RequestMapping("/toLogin")
public String toLogin(){
return "login";
}
- 配置ShiroConfig
@Configuration
public class ShiroConfig {
// 创建realm类，需要自定义类
@Bean
public UserRealm userRealm(){
return new UserRealm();
}
// DefaultWebSecurityManager
@Bean
public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
// 关联UserRealm
securityManager.setRealm(userRealm);
return securityManager;
}
// ShiroFilterFactoryBean
@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("getDefaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager){
ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
// 设置安全管理器
bean.setSecurityManager(defaultWebSecurityManager);
// 添加Shiro的内置过滤器
/**
* anno:无需认证就可以访问
* authc：必须认证了才能访问
* user：必须拥有记住我功能才能用
* perms：拥有对某个资源的权限才能访问
* role：拥有某个角色权限才能访问
*/
// 使用map来指定过滤器
Map<String, String> map = new LinkedHashMap<String, String>();
// map.put("/user/*", "authc")
map.put("/user/add", "authc");
map.put("/user/del", "authc");
bean.setFilterChainDefinitionMap(map);
// 设置登录页面
bean.setLoginUrl("/toLogin");
return bean;
}
}
如上设置了过滤器还有，没有认证的要跳转到登录的页面
3、Shiro实现用户认证
- 在Controller中加一个login
@RequestMapping("/login")
public String login(String username, String password, Model model){
// 获取当前用户
Subject subject = SecurityUtils.getSubject();
// 封装用户的登录数据
UsernamePasswordToken token = new UsernamePasswordToken(username, password);
// 登录 执行登录的方法
try {
subject.login(token);
return "index";
} catch (UnknownAccountException e) { // 用户名不存在
model.addAttribute("msg", "用户名错误");
return "login";
} catch (IncorrectCredentialsException e){// 密码错误
model.addAttribute("msg", "密码错误");
return "login";
}
}
- 自定义UserRealm中做认证处理
// 自定义
public class UserRealm extends AuthorizingRealm {
// 授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行了授权=》doGetAuthorizationInfo");
return null;
}
// 认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
System.out.println("执行了认证=》doGetAuthenticationInfo");
// 用户名、密码 对接数据库
String username = "root"; // 先伪造一手
String password = "123";
UsernamePasswordToken userToken = (UsernamePasswordToken) token;
// 如果账号不正确就认证失败
if(!userToken.getUsername().equals(username)) return null;
// 密码认证是Shiro帮你做了
return new SimpleAuthenticationInfo("", password, "");
}
}
DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Titletitle>
head>
<body>
<p th:text="${msg}" style="color: red;">p>
<h1>登录页面h1>
<form th:action="@{/login}">
<p>用户名：<input type="text" name="username"> p><br>
<p>密码：<input type="password" name="password"> p><br>
<p><input type="submit"> p>
form>
body>
html>

- 数据库
- 老生常谈
pojo
public class User {
private Integer id;
private String name;
private String pwd;
public User(Integer id, String name, String password) {
this.id = id;
this.name = name;
this.pwd = password;
}
public User() {
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return pwd;
}
public void setPassword(String password) {
this.pwd = password;
}
@Override
public String toString() {
return "User{" +
"id=" + id +
", name='" + name + '\'' +
", password='" + pwd + '\'' +
'}';
}
}
mapper
@Mapper
public interface UserMapper extends BaseMapper<User> {
}
service 和 serviceImpl
public interface UserService extends IService<User> {
}
@Service
public class UserServiceImpl extends ServiceImpl<UserMapper, User> implements UserService{
}
- 自定义realm接入数据库
// 自定义
public class UserRealm extends AuthorizingRealm {
@Autowired
private UserService userService;
// 授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行了授权=》doGetAuthorizationInfo");
return null;
}
// 认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
System.out.println("执行了认证=》doGetAuthenticationInfo");
// 用户名、密码 对接数据库
UsernamePasswordToken userToken = (UsernamePasswordToken) token;
// 连接真实的数据库
LambdaQueryWrapper<User> lqw = new LambdaQueryWrapper<>();
lqw.eq(User::getName, userToken.getUsername());
User user = userService.getOne(lqw);
if(user == null) {
return null;
}
// 密码认证是Shiro帮你做了，Shiro加密
return new SimpleAuthenticationInfo("", user.getPassword(), "");
}
}
此时就可以将数据库中的数据接入到Realm中，实现输入的账号密码对接数据库
5、Shiro整合MD5盐值加密
- 数据库中加入盐值的字段
-
pojo对应的实体类
-
Md5Utils
public class Md5Utils {
public static String getSalt(int n){
char[] chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz01234567890!@#$%^&*()".toCharArray();
StringBuilder stringBuilder = new StringBuilder();
for (int i = 0; i < n; i++) {
char c = chars[new Random().nextInt(chars.length)];
stringBuilder.append(c);
}
return stringBuilder.toString();
}
public static List<String> encryption(String password){
List<String> msg = new ArrayList<>();
String salt = getSalt(10);
msg.add(salt);
Md5Hash MD5 = new Md5Hash(password, salt, 1024);
msg.add(MD5.toHex());
// 其中msg[0]是盐值，msg[1]是加密后的密码，可以一并保存至数据库中。
return msg;
}
}
- 配置密码匹配器
ShiroConfig
/**
* 密码匹配器
* @return HashedCredentialsMatcher
*/
@Bean("hashedCredentialsMatcher")
public HashedCredentialsMatcher hashedCredentialsMatcher(){
HashedCredentialsMatcher matcher = new HashedCredentialsMatcher();
// 设置哈希算法名称
matcher.setHashAlgorithmName("MD5");
// 设置哈希迭代次数
matcher.setHashIterations(1024);
// 设置存储凭证(true:十六进制编码,false:base64)
matcher.setStoredCredentialsHexEncoded(true);
return matcher;
}
// 创建realm类，需要自定义类
@Bean
public UserRealm userRealm(@Qualifier("hashedCredentialsMatcher") HashedCredentialsMatcher matcher){
UserRealm userRealm = new UserRealm();
userRealm.setCredentialsMatcher(matcher);
return userRealm;
}
- 接入Md5加密
MyRealm
// 认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
System.out.println("执行了认证=》doGetAuthenticationInfo");
// 用户名、密码 对接数据库
UsernamePasswordToken userToken = (UsernamePasswordToken) token;
// 连接真实的数据库
LambdaQueryWrapper<User> lqw = new LambdaQueryWrapper<>();
lqw.eq(User::getName, userToken.getUsername());
User user = userService.getOne(lqw);
if(user != null) {
return new SimpleAuthenticationInfo(user, user.getPwd(), ByteSource.Util.bytes(user.getSalt()), getName());
}
return null;
}
此时你可以使用Md5工具去生成几个例子，将数据库中的密码和盐值换成你生成，然后去试一试，如果要注册的时候，在注册逻辑中把密码加密，和盐值的逻辑加入即可
6、Shiro实现授权
- 数据库
加一个权限的字段
修改pojo对应的实体类
进行授权判断
ShiroConfig
// ShiroFilterFactoryBean
@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("getDefaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager){
ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
// 设置安全管理器
bean.setSecurityManager(defaultWebSecurityManager);
// 添加Shiro的内置过滤器
/**
* anno:无需认证就可以访问
* authc：必须认证了才能访问
* user：必须拥有记住我功能才能用
* perms：拥有对某个资源的权限才能访问
* role：拥有某个角色权限才能访问
*/
// 使用map来指定过滤器
Map<String, String> map = new LinkedHashMap<>();
// 授权
map.put("/user/add", "perms[user:add]");
map.put("/user/del", "perms[user:del]");
// 拦截
map.put("/user/*", "authc");
bean.setFilterChainDefinitionMap(map);
// 设置登录页面
bean.setLoginUrl("/toLogin");
// 未授权跳转
bean.setUnauthorizedUrl("/noauth");
return bean;
}
MyRealm
// 授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行了授权=》doGetAuthorizationInfo");
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
// 拿到当前用户对象
Subject subject = SecurityUtils.getSubject();
// 拿到用户对象
User currentUser = (User)subject.getPrincipal();
// 对接数据库权限
info.addStringPermission(currentUser.getPerms());
return info;
}
现在就是先登录，然后根据你数据库中的权限去做授权，然后你就能访问你对应的页面了
7、Shiro整合JWT+MD5
找了好多的资料。最后发现一个差不多的，就这样吧

三层
@Data
@AllArgsConstructor
@NoArgsConstructor
public class UserBean {
private String username;
private String password;
private String role;
private String permission;
}
@Mapper
public interface UserMapper extends BaseMapper<UserBean> {
}
public interface UserService extends IService<UserBean> {
}
@Service
public class UserServiceImpl extends ServiceImpl<UserMapper, UserBean> implements UserService {
}
JWTUtil
public class JWTUtil {
// 过期时间5分钟
private static final long EXPIRE_TIME = 5*60*1000;
/**
* 校验token是否正确
* @param token 密钥
* @param secret 用户的密码
* @return 是否正确
*/
public static boolean verify(String token, String username, String secret) {
try {
Algorithm algorithm = Algorithm.HMAC256(secret);
JWTVerifier verifier = JWT.require(algorithm)
.withClaim("username", username)
.build();
DecodedJWT jwt = verifier.verify(token);
return true;
} catch (Exception exception) {
return false;
}
}
/**
* 获得token中的信息无需secret解密也能获得
* @return token中包含的用户名
*/
public static String getUsername(String token) {
try {
DecodedJWT jwt = JWT.decode(token);
return jwt.getClaim("username").asString();
} catch (JWTDecodeException e) {
return null;
}
}
/**
* 生成签名,5min后过期
* @param username 用户名
* @param secret 用户的密码
* @return 加密的token
*/
public static String sign(String username, String secret) {
try {
Date date = new Date(System.currentTimeMillis()+EXPIRE_TIME);
Algorithm algorithm = Algorithm.HMAC256(secret);
// 附带username信息
return JWT.create()
.withClaim("username", username)
.withExpiresAt(date)
.sign(algorithm);
} catch (UnsupportedEncodingException e) {
return null;
}
}
}
restful
public class ResponseBean {
// http 状态码
private int code;
// 返回信息
private String msg;
// 返回的数据
private Object data;
public ResponseBean(int code, String msg, Object data) {
this.code = code;
this.msg = msg;
this.data = data;
}
public int getCode() {
return code;
}
public void setCode(int code) {
this.code = code;
}
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
public Object getData() {
return data;
}
public void setData(Object data) {
this.data = data;
}
}
自定义异常类
public class UnauthorizedException extends RuntimeException {
public UnauthorizedException(String msg) {
super(msg);
}
public UnauthorizedException() {
super();
}
}
Controller
@RestController
public class WebController {
private static final Logger LOGGER = LogManager.getLogger(WebController.class);
private UserService userService;
@Autowired
public void setService(UserService userService) {
this.userService = userService;
}
@PostMapping("/login")
public ResponseBean login(@RequestParam("username") String username,
@RequestParam("password") String password) {
LambdaQueryWrapper<UserBean> lqw = new LambdaQueryWrapper<>();
lqw.eq(UserBean::getUsername, username);
UserBean userBean = userService.getOne(lqw);
if (userBean.getPassword().equals(DigestUtil.md5Hex(password))) {
return new ResponseBean(200, "Login success", JWTUtil.sign(username, DigestUtil.md5Hex(password)));
} else {
throw new UnauthorizedException();
}
}
@GetMapping("/article")
public ResponseBean article() {
Subject subject = SecurityUtils.getSubject();
if (subject.isAuthenticated()) {
return new ResponseBean(200, "You are already logged in", null);
} else {
return new ResponseBean(200, "You are guest", null);
}
}
@GetMapping("/require_auth")
@RequiresAuthentication
public ResponseBean requireAuth() {
return new ResponseBean(200, "You are authenticated", null);
}
@GetMapping("/require_role")
@RequiresRoles("admin")
public ResponseBean requireRole() {
return new ResponseBean(200, "You are visiting require_role", null);
}
@GetMapping("/require_permission")
@RequiresPermissions(logical = Logical.AND, value = {"view", "edit"})
public ResponseBean requirePermission() {
return new ResponseBean(200, "You are visiting permission require edit,view", null);
}
@RequestMapping(path = "/401")
@ResponseStatus(HttpStatus.UNAUTHORIZED)
public ResponseBean unauthorized() {
return new ResponseBean(401, "Unauthorized", null);
}
}
这里在login的时候，判断输入进来的password的md5加密后的字符串是否与从数据库中查询的一样，一样的话，采取生成Token
- 处理框架异常
@RestControllerAdvice
public class ExceptionController {
// 捕捉shiro的异常
@ResponseStatus(HttpStatus.UNAUTHORIZED)
@ExceptionHandler(ShiroException.class)
public ResponseBean handle401(ShiroException e) {
return new ResponseBean(401, e.getMessage(), null);
}
// 捕捉UnauthorizedException
@ResponseStatus(HttpStatus.UNAUTHORIZED)
@ExceptionHandler(UnauthorizedException.class)
public ResponseBean handle401() {
return new ResponseBean(401, "Unauthorized", null);
}
// 捕捉其他所有异常
@ExceptionHandler(Exception.class)
@ResponseStatus(HttpStatus.BAD_REQUEST)
public ResponseBean globalException(HttpServletRequest request, Throwable ex) {
return new ResponseBean(getStatus(request).value(), ex.getMessage(), null);
}
private HttpStatus getStatus(HttpServletRequest request) {
Integer statusCode = (Integer) request.getAttribute("javax.servlet.error.status_code");
if (statusCode == null) {
return HttpStatus.INTERNAL_SERVER_ERROR;
}
return HttpStatus.valueOf(statusCode);
}
}
- JWTToken
public class JWTToken implements AuthenticationToken {
// 密钥
private String token;
public JWTToken(String token) {
this.token = token;
}
@Override
public Object getPrincipal() {
return token;
}
@Override
public Object getCredentials() {
return token;
}
}
- 实现Realm
@Service
public class MyRealm extends AuthorizingRealm {
private static final Logger LOGGER = LogManager.getLogger(MyRealm.class);
private UserService userService;
@Autowired
public void setUserService(UserService userService) {
this.userService = userService;
}
/**
* 大坑！，必须重写此方法，不然Shiro会报错
*/
@Override
public boolean supports(AuthenticationToken token) {
return token instanceof JWTToken;
}
/**
* 只有当需要检测用户权限的时候才会调用此方法，例如checkRole,checkPermission之类的
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
String username = JWTUtil.getUsername(principals.toString());
LambdaQueryWrapper<UserBean> lqw = new LambdaQueryWrapper<>();
lqw.eq(UserBean::getUsername, username);
UserBean user = userService.getOne(lqw);
SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();
simpleAuthorizationInfo.addRole(user.getRole());
Set<String> permission = new HashSet<>(Arrays.asList(user.getPermission().split(",")));
simpleAuthorizationInfo.addStringPermissions(permission);
return simpleAuthorizationInfo;
}
/**
* 默认使用此方法进行用户名正确与否验证，错误抛出异常即可。
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken auth) throws AuthenticationException {
String token = (String) auth.getCredentials();
// 解密获得username，用于和数据库进行对比
String username = JWTUtil.getUsername(token);
if (username == null) {
throw new AuthenticationException("token invalid");
}
LambdaQueryWrapper<UserBean> lqw = new LambdaQueryWrapper<>();
lqw.eq(UserBean::getUsername, username);
UserBean userBean = userService.getOne(lqw);
if (userBean == null) {
throw new AuthenticationException("User didn't existed!");
}
if (!JWTUtil.verify(token, username, userBean.getPassword())) {
throw new AuthenticationException("Username or password error");
}
return new SimpleAuthenticationInfo(token, token, "my_realm");
}
}
鉴权和认证最终都是在这里，这里我觉得认证和Spring Secuity是差不多的，只不过Spring Secuity可以一个api就搞完了，顺便还能验证加密的账户信息，而我这里在login是手动的去做的
- JWTFilter
public class JWTFilter extends BasicHttpAuthenticationFilter {
private Logger LOGGER = LoggerFactory.getLogger(this.getClass());
/**
* 判断用户是否想要登入。
* 检测header里面是否包含Authorization字段即可
*/
@Override
protected boolean isLoginAttempt(ServletRequest request, ServletResponse response) {
HttpServletRequest req = (HttpServletRequest) request;
String authorization = req.getHeader("Authorization");
return authorization != null;
}
/**
*
*/
@Override
protected boolean executeLogin(ServletRequest request, ServletResponse response) throws Exception {
HttpServletRequest httpServletRequest = (HttpServletRequest) request;
String authorization = httpServletRequest.getHeader("Authorization");
JWTToken token = new JWTToken(authorization);
// 提交给realm进行登入，如果错误他会抛出异常并被捕获
getSubject(request, response).login(token);
// 如果没有抛出异常则代表登入成功，返回true
return true;
}
/**
* 这里我们详细说明下为什么最终返回的都是true，即允许访问
* 例如我们提供一个地址 GET /article
* 登入用户和游客看到的内容是不同的
* 如果在这里返回了false，请求会被直接拦截，用户看不到任何东西
* 所以我们在这里返回true，Controller中可以通过 subject.isAuthenticated() 来判断用户是否登入
* 如果有些资源只有登入用户才能访问，我们只需要在方法上面加上 @RequiresAuthentication 注解即可
* 但是这样做有一个缺点，就是不能够对GET,POST等请求进行分别过滤鉴权(因为我们重写了官方的方法)，但实际上对应用影响不大
*/
@Override
protected boolean isAccessAllowed(ServletRequest request, ServletResponse response, Object mappedValue) {
if (isLoginAttempt(request, response)) {
try {
executeLogin(request, response);
} catch (Exception e) {
response401(request, response);
}
}
return true;
}
/**
* 对跨域提供支持
*/
@Override
protected boolean preHandle(ServletRequest request, ServletResponse response) throws Exception {
HttpServletRequest httpServletRequest = (HttpServletRequest) request;
HttpServletResponse httpServletResponse = (HttpServletResponse) response;
httpServletResponse.setHeader("Access-control-Allow-Origin", httpServletRequest.getHeader("Origin"));

httpServletResponse.setHeader("Access-Control-Allow-Headers", httpServletRequest.getHeader("Access-Control-Request-Headers"));
// 跨域时会首先发送一个option请求，这里我们给option请求直接返回正常状态
if (httpServletRequest.getMethod().equals(RequestMethod.OPTIONS.name())) {
httpServletResponse.setStatus(HttpStatus.OK.value());
return false;
}
return super.preHandle(request, response);
}
/**

private void response401(ServletRequest req, ServletResponse resp) {
try {
HttpServletResponse httpServletResponse = (HttpServletResponse) resp;

我觉得这个过滤器更像是一个路由，
getSubject(request, response).login(token);这个还是重点
- ShiroConfig
@Configuration
public class ShiroConfig {
@Bean("securityManager")
public DefaultWebSecurityManager getManager(MyRealm realm) {
DefaultWebSecurityManager manager = new DefaultWebSecurityManager();
// 使用自己的realm
manager.setRealm(realm);
/*
* 关闭shiro自带的session，详情见文档
* http://shiro.apache.org/session-management.html#SessionManagement-StatelessApplications%28Sessionless%29
*/
DefaultSubjectDAO subjectDAO = new DefaultSubjectDAO();
DefaultSessionStorageEvaluator defaultSessionStorageEvaluator = new DefaultSessionStorageEvaluator();
defaultSessionStorageEvaluator.setSessionStorageEnabled(false);
subjectDAO.setSessionStorageEvaluator(defaultSessionStorageEvaluator);
manager.setSubjectDAO(subjectDAO);
return manager;
}
@Bean("shiroFilter")
public ShiroFilterFactoryBean factory(DefaultWebSecurityManager securityManager) {
ShiroFilterFactoryBean factoryBean = new ShiroFilterFactoryBean();
// 添加自己的过滤器并且取名为jwt
Map<String, Filter> filterMap = new HashMap<>();
filterMap.put("jwt", new JWTFilter());
factoryBean.setFilters(filterMap);
factoryBean.setSecurityManager(securityManager);
factoryBean.setUnauthorizedUrl("/401");
/*
* 自定义url规则
* http://shiro.apache.org/web.html#urls-
*/
Map<String, String> filterRuleMap = new HashMap<>();
// 所有请求通过我们自己的JWT Filter
filterRuleMap.put("/**", "jwt");
// 访问401和404页面不通过我们的Filter
filterRuleMap.put("/401", "anon");
factoryBean.setFilterChainDefinitionMap(filterRuleMap);
return factoryBean;
}
/**
* 下面的代码是添加注解支持
*/
@Bean
@DependsOn("lifecycleBeanPostProcessor")
public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator();
// 强制使用cglib，防止重复代理和可能引起代理出错的问题
// https://zhuanlan.zhihu.com/p/29161098
defaultAdvisorAutoProxyCreator.setProxyTargetClass(true);
return defaultAdvisorAutoProxyCreator;
}
@Bean
public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {
return new LifecycleBeanPostProcessor();
}
@Bean
public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(DefaultWebSecurityManager securityManager) {
AuthorizationAttributeSourceAdvisor advisor = new AuthorizationAttributeSourceAdvisor();
advisor.setSecurityManager(securityManager);
return advisor;
}
}
首先是关掉了Shiro的默认的session，然后去做拦截器规则和拦截的配置，将我们前面配置的JwtFilter拿过来，意思就是把所有的请求都拦截到，统一放到JwtFilter去做处理
