3、MyController

/**
* Description: 接口

* @author zygui
* @date 2020/4/23 11:16
*/
@Controller
public class MyController {
@GetMapping({"/", "/index"})
public String toIndex(Model model) {
model.addAttribute("msg", "Hello Shiro !");
return "index";
}
@GetMapping("/user/add")
public String add() {
return "user/add";
}
@GetMapping("/user/update")
public String update() {
return "user/update";
}
@GetMapping("/toLogin")
public String toLogin() {
return "login";
}
@PostMapping("/login") // 会执行UserRealm的认证方法
public String login(String username, String password, Model model) {
// 获取当前的用户
Subject subject = SecurityUtils.getSubject();
// 封装用户的登录数据(这个数据在doGetAuthenticationInfo中拿到了)
UsernamePasswordToken token = new UsernamePasswordToken(username, password);
// 执行登录的方法
try {
subject.login(token);
return "index";
} catch (UnknownAccountException e) {
// 用户名不存在异常
model.addAttribute("msg", "用户名不存在/错误");

}

4、自定义UserRealm
跳转到目录
/**
* Description: 自定义UserRealm, 需要继承AuthorizingRealm
*
* @author zygui

*/
public class UserRealm extends AuthorizingRealm {
@Autowired
private UserService userService;
/*
用户在前台登录的时候, 此时会调用下面的两个方法
*/
// 授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行了->授权UserRealm.doGetAuthorizationInfo");
// 用来存储授权的对象
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
// 给用户添加user:add权限
//info.addStringPermission("user:add");
// 拿到当前登录的这个对象(认证中的user)
Subject subject = SecurityUtils.getSubject();
User currentUser = (User) subject.getPrincipal();
// 从数据库中获取该角色的权限,并授权
info.addStringPermission(currentUser.getPerms()); // 从数据库中获取角色的权限
return info;
}
// 认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
System.out.println("执行了->认证UserRealm.doGetAuthenticationInfo");
// 用户名,密码
// String name = "root";
// String password = "123";
UsernamePasswordToken userToken = (UsernamePasswordToken) authenticationToken;
// 从数据库中获取用户: userToken.getUsername()就是前台用户输入的用户名
User user = userService.queryUserByName(userToken.getUsername());
if (user == null) {
return null; // 抛出异常 UnknowAccountException
}
// 用户名认证
// if (!userToken.getUsername().equals(name)) {
// return null; // 抛出异常 UnknowAccountException
// }
// 密码认证, Shiro自动帮我们做; 加密了
return new SimpleAuthenticationInfo(user, user.getPwd(), "");
}

5、ShiroConfig 配置类

@Configuration

/*
Shiro的三个核心!
Subject: 用户
SecurityManager: 管理所有用户
Realm: 连接数据
*/

@Bean
public ShiroFilterFactoryBean shiroFilterFactoryBean() {
ShiroFilterFactoryBean filterFactoryBean = new ShiroFilterFactoryBean();
// 设置安全管理器(Bean的依赖注入)
filterFactoryBean.setSecurityManager(defaultWebSecurityManager());
// 拦截操作
/*
添加shiro的内置过滤器
anon: 无需认证就可以访问
authc: 必须认证(登录)才能访问
user: 必须拥存在用户才能访问
perms: 拥有对某个资源的权限才能访问
roles: 拥有某个角色权限才能访问
*/

// 授权(必须是user用户有add权限才可以访问
filterMap.put("/user/add", "perms[user:add]");
filterMap.put("/user/update", "perms[user:update]");

// filterMap.put("/user/update", "authc");

// 设置登录的请求
filterFactoryBean.setLoginUrl("/toLogin");
// 未授权页面
filterFactoryBean.setUnauthorizedUrl("/noauth");

}
// DefaultWebSecurityManager
@Bean
public DefaultWebSecurityManager defaultWebSecurityManager() {
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
// 依赖注入userRealm的bean
securityManager.setRealm(userRealm());
return securityManager;
}
// 创建Realm对象; 需要自定义Realm(继承AuthorizingRealm)
@Bean

return new UserRealm();
}
// 整合ShiroDialect, 用来整合 shiro thymeleaf
@Bean
