shrio整合springboot

以下是shiro整合SpringBoot的步骤： 1.添加Shiro和SpringBoot的依赖关系到pom.xml文件中： ```xml <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring-boot-web-starter</artifactId> <version>1.4.2</version> </dependency> ``` 2.创建ShiroConfig.java文件，并在其中配置Shiro的安全管理器、Realm、过滤器等： ```java @Configuration public class ShiroConfig { @Bean public ShiroFilterFactoryBean shiroFilterFactoryBean(DefaultWebSecurityManager securityManager) { ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean(); shiroFilterFactoryBean.setSecurityManager(securityManager); Map<String, String> filterChainDefinitionMap = new LinkedHashMap<>(); filterChainDefinitionMap.put("/login", "anon"); filterChainDefinitionMap.put("/logout", "logout"); filterChainDefinitionMap.put("/**", "authc"); shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap); return shiroFilterFactoryBean; } @Bean public DefaultWebSecurityManager securityManager(Realm realm) { DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager(); securityManager.setRealm(realm); return securityManager; } @Bean public Realm realm() { return new MyRealm(); } } ``` 3.创建MyRealm.java文件，并在其中实现自定义的Realm： ```java public class MyRealm extends AuthorizingRealm { @Autowired private UserService userService; @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) { SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo(); User user = (User) principals.getPrimaryPrincipal(); authorizationInfo.setRoles(userService.getRoles(user.getUsername())); authorizationInfo.setStringPermissions(userService.getPermissions(user.getUsername())); return authorizationInfo; } @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { UsernamePasswordToken usernamePasswordToken = (UsernamePasswordToken) token; String username = usernamePasswordToken.getUsername(); User user = userService.getUserByUsername(username); if (user == null) { throw new UnknownAccountException(); } return new SimpleAuthenticationInfo(user, user.getPassword(), getName()); } } ``` 4.创建UserController.java文件，并在其中实现用户登录和注销的接口： ```java @RestController public class UserController { @PostMapping("/login") public String login(String username, String password) { Subject subject = SecurityUtils.getSubject(); UsernamePasswordToken token = new UsernamePasswordToken(username, password); try { subject.login(token); return "login success"; } catch (AuthenticationException e) { return "login failed"; } } @GetMapping("/logout") public String logout() { Subject subject = SecurityUtils.getSubject(); subject.logout(); return "logout success"; } } ``` 5.在templates文件夹下创建login.html文件，并在其中实现用户登录的页面： ```html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Login</title> </head> <body> <form action="/login" method="post"> <div> <label for="username">Username:</label> <input type="text" id="username" name="username"> </div> <div> <label for="password">Password:</label> <input type="password" id="password" name="password"> </div> <button type="submit">Login</button> </form> </body> </html> ``` 6.启动SpringBoot应用程序，并在浏览器中访问http://localhost:8080/login，即可看到登录页面。
