Springboot+shiro+cas单点登录环境搭建

Springboot+shiro+cas单点登录环境搭建

最近这段时间忙好久没有写博客了，现在给大家上点干货，废话不多说了，

1.首先在pom.xml中添加依赖

        
			org.apache.shiro
			shiro-spring
			1.3.2
		
        
			org.jasig.cas.client
			cas-client-core
			3.3.3
		
		
			org.apache.shiro
			shiro-core
			1.3.2
		
		
			org.apache.shiro
			shiro-ehcache
			1.3.2
		
		
			org.apache.shiro
			shiro-cas
			1.3.2
			
			
				
					javax.servlet
					javax.servlet-api
				
				
					javax.servlet
					servlet-api
				
			
		
		
			commons-codec
			commons-codec
		
		
			org.opensaml
			opensaml
			1.1
		
		
			org.apache.santuario
			xmlsec
			1.4.3
			
			
				
					javax.servlet
					javax.servlet-api
				
				
					javax.servlet
					servlet-api
				
			
		

2.在application.properties中配置

#cas server地址，外网访问需用外网IP,可以写域名
cas.server-url=http://192.168.1.56:8080/cas

#当前项目地址，外网访问需用外网IP
cas.service=http://192.168.1.56

#登录成功地址
cas.service.loginSuccessUrl = "/index";

#权限认证失败跳转地址
cas.service.unauthorizedUrl = "/error.html";

3.接写下就是写类的，Springboot主要是用注解，创建 MyShiroCasRealm

package cnlink.sdwan.common.shiro.cas;

import cnlink.sdwan.dao.UserMapper;
import cnlink.sdwan.model.User;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.cas.CasRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;

import javax.annotation.PostConstruct;
import java.util.HashSet;
import java.util.Set;

/**
 * Created by Admin on 2018/12/27
 * 
 */
public class MyShiroCasRealm extends CasRealm {

    @Autowired
    private UserMapper userMapper;


    private static final Logger logger = LoggerFactory.getLogger(MyShiroCasRealm.class);

    @Value("${cas.server-url}")
    public  String casServerUrlPrefix;

    @Value("${cas.service}")
    public  String shiroServerUrlPrefix;

    @PostConstruct
    public void initProperty(){
        // cas server地址
        setCasServerUrlPrefix(casServerUrlPrefix);
        // 客户端回调地址
        setCasService(shiroServerUrlPrefix + "/cas");
    }

    /**
     * 1、CAS认证 ,验证用户身份
     * 2、将用户基本信息设置到会话中(不用了，随时可以获取的)
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) {

        AuthenticationInfo authc = super.doGetAuthenticationInfo(token);

        String account = (String) authc.getPrincipals().getPrimaryPrincipal();

        System.out.println("========"+account+"==========");

        User user=new User();
        user.setLdapAccount(account);

        user = userMapper.queryCasLogin(user);
        //将用户信息存入session中
        SecurityUtils.getSubject().getSession().setAttribute("user", user);

        return authc;
    }

    /**
     * 权限认证，为当前登录的Subject授予角色和权限
     * 本例中该方法的调用时机为需授权资源被访问时
     * 并且每次访问需授权资源时都会执行该方法中的逻辑，这表明本例中默认并未启用AuthorizationCache
     * 如果连续访问同一个URL（比如刷新），该方法不会被重复调用，Shiro有一个时间间隔（也就是cache时间，在ehcache-shiro.xml中配置），超过这个时间间隔再刷新页面，该方法会被执行
     */

    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        
        logger.info("##################Shiro权限认证##################");
        
        User user = new User();
        if(user!=null){
            //权限信息对象info,用来存放查出的用户的所有的角色（role）及权限（permission）
            SimpleAuthorizationInfo info=new SimpleAuthorizationInfo();
            //给用户添加角色（让shiro去验证）
            Set roleNames = new HashSet<>();
            if(user.getUserName().equals("admin")){
                roleNames.add("admin");
            }
            info.setRoles(roleNames);
            return info;
        }
        // 返回null的话，就会导致任何用户访问被拦截的请求时，都会自动跳转到unauthorizedUrl指定的地址
        return null;
    }

}

4.创建ShiroCasConfiguration

package cnlink.sdwan.common.shiro.cas;

import at.pollux.thymeleaf.shiro.dialect.ShiroDialect;
import org.apache.shiro.cas.CasFilter;
import org.apache.shiro.cas.CasSubjectFactory;
import org.apache.shiro.spring.LifecycleBeanPostProcessor;
import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
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.Value;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.boot.web.servlet.ServletListenerRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.web.filter.DelegatingFilterProxy;

import javax.servlet.Filter;
import java.util.HashMap;
import java.util.LinkedHashMap;
import java.util.Map;

/**

 */
@PropertySource({"classpath:application.properties"})
@Configuration

    private static final Logger logger = LoggerFactory.getLogger(ShiroCasConfiguration.class);

    @Bean(name = "myShiroCasRealm")
    public MyShiroCasRealm myShiroCasRealm() {

    }

    /**

    @Bean
    public ServletListenerRegistrationBean singleSignOutHttpSessionListener() {
        ServletListenerRegistrationBean bean = new ServletListenerRegistrationBean();
        bean.setListener(new SingleSignOutHttpSessionListener());
//        bean.setName(""); //默认为bean name
        bean.setEnabled(true);
        //bean.setOrder(Ordered.HIGHEST_PRECEDENCE); //设置优先级
        return bean;
    }

    /**

     */
    @Bean

        bean.setName("singleSignOutFilter");
        bean.setFilter(new SingleSignOutFilter());
        bean.addUrlPatterns("/*");
        bean.setEnabled(true);
        return bean;
    }

    /**
     * 注册DelegatingFilterProxy（Shiro）
     * @return
     */
    @Bean
    public FilterRegistrationBean delegatingFilterProxy() {
        FilterRegistrationBean filterRegistration = new FilterRegistrationBean();

    }

    /**

        dwsm.setRealm(myShiroCasRealm);
//      
//        dwsm.setCacheManager(getEhCacheManager());
        // 指定 SubjectFactory
        dwsm.setSubjectFactory(new CasSubjectFactory());
        return dwsm;
    }

    /**

        aasa.setSecurityManager(securityManager);
        return aasa;
    }

    @Bean
    public ShiroDialect shiroDialect() {
        return new ShiroDialect();
    }

    /**
     * CAS过滤器

到此就结束了，本人亲测过，没有问题，如有问题请留言，提前祝大家元旦快乐！
