shiro springboot3

根据引用，创建一个Spring Boot项目并引入Shiro依赖。使用以下代码创建一个配置类来配置Shiro环境。在该配置类中，您可以定义Shiro的各种配置项，例如Realm、Session管理器等。

@Configuration
public class ShiroConfig {
    // 配置Shiro的安全管理器
    @Bean
    public SecurityManager securityManager() {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(myRealm());
        return securityManager;
    }
    
    // 自定义的Realm
    @Bean
    public MyRealm myRealm() {
        return new MyRealm();
    }
    
    // 配置Shiro的过滤器链
    @Bean
    public ShiroFilterChainDefinition shiroFilterChainDefinition() {
        DefaultShiroFilterChainDefinition chainDefinition = new DefaultShiroFilterChainDefinition();
        chainDefinition.addPathDefinition("/user/logout", "logout");
        chainDefinition.addPathDefinition("/**", "authc");
        return chainDefinition;
    }
    
    // 配置Shiro的注解支持
    @Bean
    public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
        DefaultAdvisorAutoProxyCreator autoProxyCreator = new DefaultAdvisorAutoProxyCreator();
        autoProxyCreator.setProxyTargetClass(true);
        return autoProxyCreator;
    }

    @Bean
    public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {
        AuthorizationAttributeSourceAdvisor advisor = new AuthorizationAttributeSourceAdvisor();
        advisor.setSecurityManager(securityManager);
        return advisor;
    }
}

根据引用，开发一个UserController，并在其中定义一个logout()方法，用于退出登录。在该方法中，首先获取当前用户的Subject对象，然后调用subject.logout()方法退出登录。最后，使用重定向将用户重定向到登录页面。

@Controller
@RequestMapping("user")
public class UserController {
    
    @RequestMapping("logout")
    public String logout(){
        Subject subject = SecurityUtils.getSubject();
        subject.logout();//退出用户
        return "redirect:/login.jsp";
    }
}

根据引用，根据不同的Spring Boot版本，Shiro的请求处理方式可能会有所不同。在Spring Boot 2.7.10中，请求会正常进入Shiro的过滤器中(org.apache.shiro.web.servlet.OncePerRequestFilter)进行处理。

希望这些信息能对您有所帮助！<span class="em">1</span><span class="em">2</span><span class="em">3</span>
