spring boot 1.5.4 集成shiro+cas,实现单点登录和权限控制

1.添加maven依赖(先安装好cas-server-3.5.2，安装步骤请查看本文参考文章)

    <dependency>
      <groupId>org.apache.shiro</groupId>
      <artifactId>shiro-spring</artifactId>
      <version>1.2.4</version>
    </dependency>
    <dependency>
      <groupId>org.apache.shiro</groupId>
      <artifactId>shiro-ehcache</artifactId>
      <version>1.2.4</version>
    </dependency>
    <dependency>
      <groupId>org.apache.shiro</groupId>
      <artifactId>shiro-cas</artifactId>
      <version>1.2.4</version>
    </dependency>    

2.启动累添加@ServletComponentScan注解

@SpringBootApplication
public class Application {
  /**
   * main function
   * @param args params
   */
  public static void main(String[] args){
    ConfigurableApplicationContext context = SpringApplication.run(Application.class,args);
    //test if a xml bean inject into springcontext successful
    User user = (User)context.getBean("user1");
    System.out.println(JSONObject.toJSONString(user));
  }
}

 3.配置shiro+cas

package com.hdwang.config.shiroCas;
import com.hdwang.dao.UserDao;
import org.apache.shiro.cache.ehcache.EhCacheManager;
import org.apache.shiro.cas.CasFilter;
import org.apache.shiro.cas.CasSubjectFactory;

import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;

import org.apache.shiro.web.filter.authc.LogoutFilter;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.jasig.cas.client.session.SingleSignOutFilter;
import org.jasig.cas.client.session.SingleSignOutHttpSessionListener;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.web.servlet.FilterRegistrationBean;

 4.运行验证

登录

访问：http://localhost:8081/home

跳转至：https://localhost:8443/cas/login?service=http://localhost:8081/cas

输入正确用户名密码登录跳转回：http://localhost:8081/cas?ticket=ST-203-GUheN64mOZec9IWZSH1B-cas01.example.org

最终跳回：http://localhost:8081/home

登出

访问：http://localhost:8081/logout

跳转至：https://localhost:8443/cas/logout?service=http://localhost:8081

由于未登录，又执行登录步骤，所以最终返回https://localhost:8443/cas/login?service=http://localhost:8081/cas

这次登录成功后返回：http://localhost:8081/

cas server端登出（也行）

访问：https://localhost:8443/cas/logout

再访问：http://localhost:8081/home 会跳转至登录页，perfect!
