1. 创建基础项目
file ==> new ==> project ==> Spring Initializr ==>next ==> web(Spring Web)、Security(Spring Security) ==>一直下一步
2. 编写代码进行测试
创建controller
@Controller
public class LoginController {
@RequestMapping("login")
public String login(){
System.out.println("登入成功!");
return "redirect:main.html";
}
}
static下创建login.html、main.html
DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Titletitle>
head>
<body>
<form action="/login" method="post">
用户名:<input type="text" name="username"/><br/>
密码:<input type="password" name="password"/><br/>
<input type="submit" value="登入" />
form>
body>
html>
DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Titletitle>
head>
<body>
登入成功!!!
body>
html>
3. 启动项目进行测试
访问http://localhost:8080/login.html
会进入SpringSecurity框架自带的登入页面 用户默认user 密码控制台生成 输入账号密码跳转到自己定义的login.html页面证明项目搭建完成
1. 定义SecurityConfig
@Configuration
public class SecurityConfig {
@Bean
public PasswordEncoder getPw(){
return new BCryptPasswordEncoder();
}
}
2. 定义UserDetailService实现类
@Service
public class UserDetailServiceImpl implements UserDetailsService {
@Autowired
private PasswordEncoder pw;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
//根据用户名从数据库中取出用户 这里暂时写死
if (!"admin".equals(username)){
throw new UsernameNotFoundException("用户:"+username+"不存在");
}
//获取用户的密码 也暂时写死
String root = pw.encode("root");
return new User(username,root, AuthorityUtils.commaSeparatedStringToAuthorityList("admin,normal"));
}
}
3. 编写controller
@RequestMapping("toMain")
public String toMain(){
return "redirect:main.html";
}
@RequestMapping("toError")
public String toError(){
return "redirect:error.html";
}
4. 定义SecurityConfig类
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
//表单提交
http.formLogin()
//当访问/login时认为是登入,执行loadUserByUsername方法
.loginProcessingUrl("/login")
//自定义登入页面
.loginPage("/login.html")
//登入成功的页面
.successForwardUrl("/toMain")
//登入失败
.failureForwardUrl("/toError")
;
/**
* anyRequest | 匹配所有请求路径
* access | SpringEl表达式结果为true时可以访问
* anonymous | 匿名可以访问
* denyAll | 用户不能访问
* fullyAuthenticated | 用户完全认证可以访问(非remember-me下自动登录)
* hasAnyAuthority | 如果有参数,参数表示权限,则其中任何一个权限可以访问
* hasAnyRole | 如果有参数,参数表示角色,则其中任何一个角色可以访问
* hasAuthority | 如果有参数,参数表示权限,则其权限可以访问
* hasIpAddress | 如果有参数,参数表示IP地址,如果用户IP和参数匹配,则可以访问
* hasRole | 如果有参数,参数表示角色,则其角色可以访问
* permitAll | 用户可以任意访问
* rememberMe | 允许通过remember-me登录的用户访问
* authenticated | 用户登录后可访问
*/
//授权认证
http.authorizeRequests()
.antMatchers("/login.html","/error.html").permitAll()
//除上述请求任何请求都需要认证
.anyRequest().authenticated();
//关闭csrf防护
http.csrf().disable();
}
@Bean
//强散列哈希加密实现
public PasswordEncoder getPw() {
return new BCryptPasswordEncoder();
}
}
1. 定义AuthenticationSuccessHandler接口实现类、AuthenticationFailureHandler接口实现类
public class MyAuthenticationSuccessHandler implements AuthenticationSuccessHandler {
private String url;
public MyAuthenticationSuccessHandler(String url) {
this.url = url;
}
@Override
public void onAuthenticationSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException {
httpServletResponse.sendRedirect(url);
}
}
public class MyAuthenticationFailureHandler implements AuthenticationFailureHandler {
private String url;
public MyAuthenticationFailureHandler(String url) {
this.url = url;
}
@Override
public void onAuthenticationFailure(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, AuthenticationException e) throws IOException, ServletException {
httpServletResponse.sendRedirect(url);
}
}
2. 修改SecurityConfig配置类
//表单提交
http.formLogin()
//当访问/login时认为是登入,执行loadUserByUsername方法
.loginProcessingUrl("/login")
//自定义登入页面
.loginPage("/login.html")
// //登入成功的页面
// .successForwardUrl("/toMain")
//自定义登入成功处理器 不能与successForwardUrl同时使用否侧报错
.successHandler(new MyAuthenticationSuccessHandler("/main.html"))
// //登入失败
// .failureForwardUrl("/toError")
.failureHandler(new MyAuthenticationFailureHandler("/error.html"));
1. 根据权限进行过滤
//如果有参数,参数表示权限,则其中任何一个权限可以访问
.antMatchers("/main1.html").hasAnyAuthority("demo")
//如果有参数,参数表示权限,则其权限可以访问
.antMatchers("/main1.html").hasAuthority("demo")
2. 根据角色进行过滤
//如果有参数,参数表示角色,则其中任何一个角色可以访问
.antMatchers("/main1.html").hasAnyRole("test")
//如果有参数,参数表示角色,则其角色可以访问
.antMatchers("/main1.html").hasRole("test")
注意:配置角色时要以ROLE_为前缀
3. 根据ip进行过滤
.antMatchers("/main1.html").hasIpAddress("127.0.0.1")
1. 创建AccessDeniedHandler接口实现类
@Component
public class MyAccessDeniedHandler implements AccessDeniedHandler {
@Override
public void handle(HttpServletRequest request, HttpServletResponse response, AccessDeniedException accessDeniedException) throws IOException, ServletException {
//设置响应状态码
response.setStatus(HttpServletResponse.SC_FORBIDDEN);
response.setHeader("Content-Type","application/json;charset=utf-8");
PrintWriter writer = response.getWriter();
writer.write("{\"status\":\"error\",\"msg\":\"权限不足,请联系管理员\"}");
writer.flush();
writer.close();
}
}
2. 配置SecurityConfig配置类
//异常处理
http.exceptionHandling().accessDeniedHandler(myAccessDeniedHandler);
1. 编写接口
public interface MyService {
boolean hasPermission(HttpServletRequest request, Authentication authentication);
}
2. 实现接口
@Service
public class MyServiceImpl implements MyService {
@Override
public boolean hasPermission(HttpServletRequest request, Authentication authentication) {
//获取当前用户
Object o = authentication.getPrincipal();
if (o instanceof UserDetails){
UserDetails userDetails = (UserDetails) o;
Collection<? extends GrantedAuthority> authorities = userDetails.getAuthorities();
//判断拥有权限是否包含
return authorities.contains(new SimpleGrantedAuthority(request.getRequestURI()));
}
return false;
}
}
3. 修改SecurityConfig配置类
.anyRequest().access("@myServiceImpl.hasPermission(request,authentication)");
1. 启动类开启注解
@EnableGlobalMethodSecurity(securedEnabled = true)
2. controller接口上加注解
//拥有ROLE_test角色权限的用户可以访问
//@Secured("ROLE_test")
@PreAuthorize("hasRole('ROLE_test')")
@RequestMapping("toMain1")
public String toMain1(){
return "redirect:main1.html";
}
1. 所需依赖

2. 配置数据源
spring:
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3306/security?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai&allowPublicKeyRetrieval=true&verifyServerCertificate=false&useSSL=false&rewriteBatchedStatements=true
username: root
password: root
3. 配置SecurityConfig配置类
配置所需bean
@Bean
public PersistentTokenRepository getPersistentTokenRepository(){
JdbcTokenRepositoryImpl repository = new JdbcTokenRepositoryImpl();
repository.setDataSource(dataSource);
//自动建表 建完表注释掉
repository.setCreateTableOnStartup(true);
return repository;
}
@Autowired
private UserDetailServiceImpl userDetailServiceImpl;
@Autowired
private DataSource dataSource;
@Autowired
private PersistentTokenRepository persistentTokenRepository;
configure()方法添加
//记住我
http.rememberMe()
//设置过期时间 单位秒 默认两周
.tokenValiditySeconds(30)
.userDetailsService(userDetailServiceImpl)
.tokenRepository(getPersistentTokenRepository())
//设置参数名称
// .rememberMeParameter()
;
login.html新增记住我
<form action="/login" method="post">
用户名:<input type="text" name="username"/><br/>
密码:<input type="password" name="password"/><br/>
记住我:<input type="checkbox" name="remember-me" value="true" /><br/>
<input type="submit" value="登入" />
form>
1. 修改main.html
DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Titletitle>
head>
<body>
登入成功!!!<a href="/toMain1">跳转a> <a href="/logout">退出a>
body>
html>
2. 配置SecurityConfig配置类
//退出登入
http.logout().logoutSuccessUrl("/login.html");
CSRF 利用的是网站对用户网页浏览器的信任。跨站请求攻击,简单地说,是攻击者通过一些技术手段欺骗用户的浏览器去访问一个自己曾经认证过的网站并运行一些操作
默认开启生成一个类似于token的码进行身份识别
1. Oauth2认证流程:
2. 术语
3. 四种模式
授权码模式、简易授权码模式、密码模式、客户端模式
**1. ** 创建springboot项目 注入相关依赖

`password` varchar(255) CHARACTER SET utf8 COLLATE utf8_german2_ci DEFAULT NULL,
`role` varchar(255) CHARACTER SET utf8 COLLATE utf8_german2_ci DEFAULT NULL,
PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 3 CHARACTER SET = utf8 COLLATE = utf8_german2_ci ROW_FORMAT = Dynamic;
SET FOREIGN_KEY_CHECKS = 1;
3. 创建JwtUser
public class JwtUser implements UserDetails {
private Integer id;
private String username;
private String password;
public Collection<? extends GrantedAuthority> authorities;
//传入User构建JwtUser
public JwtUser(User user) {
id = user.getId();
username = user.getUsername();
password = user.getPassword();
//权限
authorities = Collections.singleton(new SimpleGrantedAuthority(user.getRole()));
}
@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
return authorities;
}
@Override
public String getPassword() {
return password;
}
@Override
public String getUsername() {
return username;
}
@Override
public boolean isAccountNonExpired() {
return true;
}
@Override
public boolean isAccountNonLocked() {
return true;
}
@Override
public boolean isCredentialsNonExpired() {
return true;
}
@Override
public boolean isEnabled() {
return true;
}
}
4. JwtUtil
package com.csf.springsecurityjwt.util;
import io.jsonwebtoken.Claims;
import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;
public class JwtUtils {
public static final String TOKEN_HEADER = "Authorization";
public static final String TOKEN_PREFIX = "Bearer ";
// TOKEN 过期时间
public static final long EXPIRATION = 1000 * 60 * 30; // 三十分钟
public static final String APP_SECRET_KEY = "secret";
private static final String ROLE_CLAIMS = "rol";
/**
* 生成token
*
* @param username
* @param role
* @return
*/
public static String createToken(String username, String role) {
Map<String, Object> map = new HashMap<>();
map.put(ROLE_CLAIMS, role);
String token = Jwts
.builder()
.setSubject(username)
.setClaims(map)
.claim("username", username)
.setIssuedAt(new Date())
.setExpiration(new Date(System.currentTimeMillis() + EXPIRATION))
.signWith(SignatureAlgorithm.HS256, APP_SECRET_KEY).compact();
return token;
}
/**
* 获取当前登录用户用户名
*
* @param token
* @return
*/
public static String getUsername(String token) {
Claims claims = Jwts.parser().setSigningKey(APP_SECRET_KEY).parseClaimsJws(token).getBody();
return claims.get("username").toString();
}
/**
* 获取当前登录用户角色
*
* @param token
* @return
*/
public static String getUserRole(String token) {
Claims claims = Jwts.parser().setSigningKey(APP_SECRET_KEY).parseClaimsJws(token).getBody();
return claims.get("rol").toString();
}
/**
* 获解析token中的信息
*
* @param token
* @return
*/
public static Claims checkJWT(String token) {
try {
final Claims claims = Jwts.parser().setSigningKey(APP_SECRET_KEY).parseClaimsJws(token).getBody();
return claims;
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
/**
* 检查token是否过期
*
* @param token
* @return
*/
public static boolean isExpiration(String token) {
Claims claims = Jwts.parser().setSigningKey(APP_SECRET_KEY).parseClaimsJws(token).getBody();
return claims.getExpiration().before(new Date());
}
}
5. 创建domain、mapper、service、controller
@Data
@EqualsAndHashCode(callSuper = false)
@Accessors(chain = true)
public class User implements Serializable {
private static final long serialVersionUID = 1L;
@TableId(value = "id", type = IdType.AUTO)
private Integer id;
private String username;
private String password;
private String role;
}
@Data
public class UserDto implements Serializable {
private String username;
private String password;
}
public interface UserMapper extends BaseMapper<User> {
}
public interface IUserService extends IService<User> {
User findByUsername(String username);
}
@Service
public class UserServiceImpl extends ServiceImpl<UserMapper, User> implements IUserService {
@Override
public User findByUsername(String username) {
LambdaQueryWrapper<User> wrapper = new QueryWrapper<User>().lambda();
wrapper.eq(User::getUsername,username);
return getOne(wrapper);
}
}
@RestController
@RequestMapping("/user")
public class UserController {
@Autowired
private IUserService userServiceImpl;
@Autowired
private BCryptPasswordEncoder bCryptPasswordEncoder;
@PostMapping("saveUser")
//添加账户
public User saveUser(@RequestBody UserDto dto){
User user = new User();
BeanUtils.copyProperties(dto, user);
user.setPassword(bCryptPasswordEncoder.encode(dto.getPassword()));
//判断是否是admin账户
if("admin".equals(dto.getUsername())){
user.setRole("ADMIN");
}else {
user.setRole("USER");
}
userServiceImpl.save(user);
return user;
}
@GetMapping("getUserByName")
public User getUserByName(@RequestParam String username){
return userServiceImpl.findByUsername(username);
}
@GetMapping("/findAll")
@PreAuthorize("hasAnyAuthority('ADMIN')") //这一步很重要 拥有ADMIN权限的用户才能访问该请求
public List<User> findAll(){
return userServiceImpl.list();
}
}
6. 创建登入验证、SecurityConfig、拦截器
@Service
public class JwtUserServiceImpl implements UserDetailsService {
@Autowired
private IUserService userServiceImpl;
@Override
//根据用户传入的信息去数据库查询是否存在该用户
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
User user = userServiceImpl.findByUsername(username);
if (user != null){
JwtUser jwtUser = new JwtUser(user);
return jwtUser;
}else {
try {
throw new UsernameNotFoundException("用户不存在");
} catch (UsernameNotFoundException e) {
e.printStackTrace();
}
}
return null;
}
}
@EnableWebSecurity
// 只有加了@EnableGlobalMethodSecurity(prePostEnabled=true) 那么在上面使用的 @PreAuthorize(“hasAuthority(‘admin’)”)才会生效
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private JwtUserServiceImpl jwtUserServiceImpl;
@Bean
public BCryptPasswordEncoder bCryptPasswordEncoder() {
return new BCryptPasswordEncoder();
}
/**
* 这边 通过重写configure(),去数据库查询用户是否存在
* @param auth
* @throws Exception
*/
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(jwtUserServiceImpl).passwordEncoder(bCryptPasswordEncoder());
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.cors().and().csrf().disable()
.authorizeRequests()
// 以/user 开头的请求 不需要进行验证
// .antMatchers("/user/**").permitAll()
// 其他都放行了
.anyRequest().authenticated()
.and()
.addFilter(new JWTAuthenticationFilter(authenticationManager())) // 用户登录拦截
.addFilter(new JWTAuthorizationFilter(authenticationManager())) // 权限拦截
// 不需要session
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and()
.exceptionHandling();
}
@Bean
CorsConfigurationSource corsConfigurationSource() {
final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**", new CorsConfiguration().applyPermitDefaultValues());
return source;
}
}
/**
* 验证用户名密码正确后,生成一个token,并将token返回给客户端
* 该类继承自UsernamePasswordAuthenticationFilter,重写了其中的2个方法 ,
* attemptAuthentication:接收并解析用户凭证。
* successfulAuthentication:用户成功登录后,这个方法会被调用,我们在这个方法里生成token并返回。
*/
public class JWTAuthenticationFilter extends UsernamePasswordAuthenticationFilter {
private AuthenticationManager authenticationManager;
/**
* security拦截默认是以POST形式走/login请求,我们这边设置为走/token请求
* @param authenticationManager
*/
public JWTAuthenticationFilter(AuthenticationManager authenticationManager) {
this.authenticationManager = authenticationManager;
super.setFilterProcessesUrl("/login");
}
/**
* 接收并解析用户凭证
* @param request
* @param response
* @return
* @throws AuthenticationException
*/
@Override
public Authentication attemptAuthentication(HttpServletRequest request,
HttpServletResponse response) throws AuthenticationException {
// 从输入流中获取到登录的信息
try {
User loginUser = new ObjectMapper().readValue(request.getInputStream(), User.class);
return authenticationManager.authenticate(
new UsernamePasswordAuthenticationToken(loginUser.getUsername(), loginUser.getPassword())
);
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
// 成功验证后调用的方法
// 如果验证成功,就生成token并返回
@Override
protected void successfulAuthentication(HttpServletRequest request,
HttpServletResponse response,
FilterChain chain,
Authentication authResult) throws IOException, ServletException {
JwtUser jwtUser = (JwtUser) authResult.getPrincipal();
System.out.println("jwtUser:" + jwtUser.toString());
String role = "";
Collection<? extends GrantedAuthority> authorities = jwtUser.getAuthorities();
for (GrantedAuthority authority : authorities) {
role = authority.getAuthority();
}
String token = JwtUtils.createToken(jwtUser.getUsername(), role);
// 返回创建成功的token 但是这里创建的token只是单纯的token
// 按照jwt的规定,最后请求的时候应该是 `Bearer token`
response.setCharacterEncoding("UTF-8");
response.setContentType("application/json; charset=utf-8");
String tokenStr = JwtUtils.TOKEN_PREFIX + token;
response.setHeader("token", tokenStr);
}
// 失败 返回错误就行
@Override
protected void unsuccessfulAuthentication(HttpServletRequest request, HttpServletResponse response, AuthenticationException failed) throws IOException, ServletException {
response.getWriter().write("authentication failed, reason: " + failed.getMessage());
}
}
public class JWTAuthorizationFilter extends BasicAuthenticationFilter {
public JWTAuthorizationFilter(AuthenticationManager authenticationManager) {
super(authenticationManager);
}
@SneakyThrows
@Override
protected void doFilterInternal(HttpServletRequest request,
HttpServletResponse response,
FilterChain chain) throws IOException, ServletException {
String tokenHeader = request.getHeader(JwtUtils.TOKEN_HEADER);
// 如果请求头中没有Authorization信息则直接放行了
if (tokenHeader == null || !tokenHeader.startsWith(JwtUtils.TOKEN_PREFIX)) {
chain.doFilter(request, response);
return;
}
// 如果请求头中有token,则进行解析,并且设置认证信息
SecurityContextHolder.getContext().setAuthentication(getAuthentication(tokenHeader));
super.doFilterInternal(request, response, chain);
}
// 这里从token中获取用户信息并新建一个token 就是上面说的设置认证信息
private UsernamePasswordAuthenticationToken getAuthentication(String tokenHeader) throws Exception {
String token = tokenHeader.replace(JwtUtils.TOKEN_PREFIX, "");
// 检测token是否过期 如果过期会自动抛出错误
JwtUtils.isExpiration(token);
String username = JwtUtils.getUsername(token);
String role = JwtUtils.getUserRole(token);
if (username != null) {
return new UsernamePasswordAuthenticationToken(username, null,
Collections.singleton(new SimpleGrantedAuthority(role))
);
}
return null;
}
}
7. 启动项目开始测试
