3.3、数据库设计
数据库跟上一篇一样，看过的跳过
shiro_user表：
DROP TABLE IF EXISTS `shiro_user`;
CREATE TABLE `shiro_user` (
`ID` int(11) NOT NULL AUTO_INCREMENT,
`USER_NAME` varchar(255) CHARACTER SET latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL,
`PASSWORD` varchar(255) CHARACTER SET latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL,
PRIMARY KEY (`ID`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 2 CHARACTER SET = latin1 COLLATE = latin1_swedish_ci ROW_FORMAT = Dynamic;
INSERT INTO `shiro_user` VALUES (1, 'test', '123456');
shiro_user_role表：
DROP TABLE IF EXISTS `shiro_user_role`;
CREATE TABLE `shiro_user_role` (
`ID` int(11) NOT NULL AUTO_INCREMENT,
`USER_NAME` varchar(255) CHARACTER SET latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL,
`ROLE_NAME` varchar(255) CHARACTER SET latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL,
PRIMARY KEY (`ID`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 2 CHARACTER SET = latin1 COLLATE = latin1_swedish_ci ROW_FORMAT = Dynamic;
INSERT INTO `shiro_user_role` VALUES (1, 'test', 'role1');
shiro_role_permission表：
DROP TABLE IF EXISTS `shiro_role_permission`;
CREATE TABLE `shiro_role_permission` (
`ID` int(11) NOT NULL AUTO_INCREMENT,
`ROLE_NAME` varchar(255) CHARACTER SET latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL,
`PERM_NAME` varchar(255) CHARACTER SET latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL,
PRIMARY KEY (`ID`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 2 CHARACTER SET = latin1 COLLATE = latin1_swedish_ci ROW_FORMAT = Dynamic;
INSERT INTO `shiro_role_permission` VALUES (1, 'role1', 'perm1');
3.4、程序的入口
Application.java类是springBoot程序的入口
@SpringBootApplication
//扫描你项目所有的java类
@ComponentScan(basePackages = {"com.huihui"})
//扫描mapper所在的位置
@MapperScan({"com.huihui.chapter2.mapper"})
public class Application {
public static void main(String[] args) throws Exception{
SpringApplication.run(Application.class,args);
}
}
3.5、开始写接口代码
先看一下项目的结构
image.png
代码从数据库开始写起：
@Repository
public interface UserMapper {
String queryUserPassword(@Param("userName")String userName);
List queryUserRole(@Param("userName")String userName);
List queryRolePermission(@Param("roleName")String roleName);
List queryUserPermission(@Param("userName")String userName);
}
mapper对应的xml文件：
接下来是service：
@Service
public class UserService {
@Autowired
UserMapper userMapper;
@Autowired
MyUserRealm myUserRealm;
/**
* 登录
* @param username
* @param password
* @throws Exception
*/
public void doLogin(String username, String password) throws Exception {
Subject currentUser = SecurityUtils.getSubject();
if (!currentUser.isAuthenticated()) {
UsernamePasswordToken token = new UsernamePasswordToken(username, password);
token.setRememberMe(true);//是否记住用户
try {
currentUser.login(token);//执行登录
} catch (UnknownAccountException uae) {
throw new Exception("账户不存在");
} catch (IncorrectCredentialsException ice) {
throw new Exception("密码不正确");
} catch (LockedAccountException lae) {
throw new Exception("用户被锁定了 ");
} catch (AuthenticationException ae) {
ae.printStackTrace();
throw new Exception("未知错误");
}
}
}
/**
* 根据用户名查询密码
* @param userName
* @return
*/
public String queryUserPassword(String userName){
return userMapper.queryUserPassword(userName);
}
/**
* 查询当前用户对应的权限
* @param userName
* @return
*/
public List queryUserPermission(String userName){
return userMapper.queryUserPermission(userName);
}
}
controller：
@Controller
public class UserController {
@Autowired
UserService userService;
@RequestMapping(value = "/index",method = RequestMethod.POST)
public String goLogin() {
return "/index.html";
}
@RequestMapping(value = "/logout",method = RequestMethod.POST)
public String login() {
Subject currentUser = SecurityUtils.getSubject();
currentUser.logout();
return "/index.html";
}
@RequestMapping(value = "/",method = RequestMethod.GET)
public String index() {
return "/index.html";
}
@RequestMapping(value = "/login",method = RequestMethod.POST)
public String login(String username, String password) {
try {
userService.doLogin(username, password);
} catch (Exception e) {
return "redirect:/hello";
}
return "redirect:/hello";
}
@RequestMapping(value = "/hello")
public String hello(){
return "hello.html";
}
@RequestMapping(value = "/hello1")
//需要访问此接口的权限
@RequiresPermissions("perm3")
public String hello1(){
return "hello2.html";
}
}
写一个异常拦截器，拦截没有权限和未登录的异常：
@ControllerAdvice
public class ExceptionInterceptor {
@ExceptionHandler({ UnauthorizedException.class, AuthorizationException.class })
public String authorizationException(HttpServletRequest req, HttpServletResponse response, Exception e) {
return "没有权限";
}
@ExceptionHandler({ UnauthenticatedException.class, AuthenticationException.class })
public String authenticationException(HttpServletRequest req, HttpServletResponse response, Exception e) {
return "请登录";
}
}
写一个Realm继承AuthorizingRealm，重写获取权限，登录等方法：
public class MyUserRealm extends AuthorizingRealm {
@Autowired
UserService userService;
public AuthorizationInfo queryAuthorizationInfo(PrincipalCollection principals){
return this.getAuthorizationInfo(principals);
}
// 获取用户的权限
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
String userName = principals.fromRealm(getName()).iterator().next().toString();
if(userName != null){
//获取用户所有权限 根据自己的需求编写获取授权信息，这里简化代码获取了用户对应的所有权限
List perms = userService.queryUserPermission(userName);
if(perms != null && !perms.isEmpty()){
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
for(String each : perms){
//将权限添加到用户信息中
info.addStringPermission(each);
}
return info;
}
}
return null;
}
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
UsernamePasswordToken token = (UsernamePasswordToken)authenticationToken;
//通过表单接受的用户名，调用currentUser.login的时候执行
String userName = token.getUsername();
if(userName != null && !"".equals(userName)){
//查询密码
String password = userService.queryUserPassword(userName);
if(password != null){
return new SimpleAuthenticationInfo(userName,password,getName());
}
}
return null;
}
@Override
public void clearCachedAuthorizationInfo(PrincipalCollection principals) {
super.clearCachedAuthorizationInfo(principals);
}
@Override
public void clearCachedAuthenticationInfo(PrincipalCollection principals) {
super.clearCachedAuthenticationInfo(principals);
}
@Override
public void clearCache(PrincipalCollection principals) {
super.clearCache(principals);
}
}
接下来写一些配置的属性，可以写在配置文件里面，也可以用java类代替，我这边是用java类直接写的：
@Configuration
public class ShiroUserConfig {
@Bean
public MyUserRealm myUserRealm(){
MyUserRealm realm = new MyUserRealm();
return realm;
}
@Bean
public DefaultWebSecurityManager securityManager(){
DefaultWebSecurityManager webSecurityManager = new DefaultWebSecurityManager();
webSecurityManager.setRealm(myUserRealm());
return webSecurityManager;
}
@Bean(name = "shiroFilter")
public ShiroFilterFactoryBean shiroFilter(){
ShiroFilterFactoryBean factoryBean = new ShiroFilterFactoryBean();
factoryBean.setSecurityManager(securityManager());
// 配置访问权限
LinkedHashMap filterChainDefinitionMap = new LinkedHashMap<>();
//filterChainDefinitionMap.put("/index", "anon"); // 表示可以匿名访问
// filterChainDefinitionMap.put("/*", "authc");// 表示需要认证才可以访问
// filterChainDefinitionMap.put("/user/login", "perms[权限添加]");
factoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
return factoryBean;
}
/*** 开启Shiro的注解*/
@Bean
public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {
return new LifecycleBeanPostProcessor();
}
@Bean
public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
DefaultAdvisorAutoProxyCreator creator = new DefaultAdvisorAutoProxyCreator();
creator.setProxyTargetClass(true);
return creator;
}
@Bean
public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor() {
AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
authorizationAttributeSourceAdvisor.setSecurityManager(securityManager());
return authorizationAttributeSourceAdvisor;
}
OK，接口准备完毕了，接下来写几个简单的页面测试一下：
image.png
index.html
hello.html
hello2.html跟error.html随便写点东西
OK，到这里代码及写完了
