springboot 下将shiro-cas替换为buji-pac4j

1.在pom.xml中添加：

<dependency>
    <groupId>org.pac4jgroupId>
    <artifactId>pac4j-casartifactId>
    <version>2.1.0version>
dependency>
<dependency>
    <groupId>io.bujigroupId>
    <artifactId>buji-pac4jartifactId>
    <version>3.0.0version>
dependency>

2.新增Pac4jConfig.java文件

import org.pac4j.cas.client.CasClient;
import org.pac4j.cas.config.CasConfiguration;
import org.pac4j.core.authorization.authorizer.RequireAnyRoleAuthorizer;
import org.pac4j.core.client.Clients;
import org.pac4j.core.config.Config;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class Pac4jConfig {
    //地址为：cas地址
      @Value("${shiro.cas}") String casServerUrlPrefix;
	
    //地址为：验证返回后的项目地址：http://localhost:8080
    @Value("${shiro.server}")
    String shiroServerUrlPrefix;
  
    //相当于一个标志，可以随意，shiroConfig中也会用到
    @Value("${pac4j.clientName}")
    String clientName;

    @Bean
    public Config config() {


        // CAS
        final CasConfiguration configuration = new CasConfiguration(casServerUrlPrefix + "/login", casServerUrlPrefix);
        configuration.setAcceptAnyProxy(true);
        CasClient casClient = new CasClient(configuration);
        casClient.setCallbackUrl(shiroServerUrlPrefix + "/callback?client_name=" + clientName);
        casClient.setName(clientName);


        final Clients clients = new Clients(shiroServerUrlPrefix + "/callback?client_name="+clientName, casClient);

        final Config config = new Config(clients);
        return config;
    }
}

3.修改ShiroConfig.java文件

    增加 

//引用的包
import org.pac4j.core.config.Config;
//需要注入
@Autowired
private Config config;

//在类中添加下面三个方法
 @Bean(name = "securityManager")
    public SecurityManager securityManager() {
      
         DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
         Pac4jRealm casRealm = pac4jRealm();
        securityManager.setRealm(casRealm);
        securityManager.setSubjectFactory(subjectFactory());
        //securityManager.setCacheManager(ehCacheManager());
        return securityManager;
    }
@Bean(name = "pac4jRealm")
    public Pac4jRealm pac4jRealm() {
        //Pac4jRealm realm = new MyShiroRealm();
        Pac4jRealm myShiroRealm = new MyShiroRealm();
        return myShiroRealm;
    }

@Bean(name = "subjectFactory")
    public Pac4jSubjectFactory subjectFactory() {
        Pac4jSubjectFactory subjectFactory = new Pac4jSubjectFactory();
        return subjectFactory;
    }

修改Bean  shiroFilter 方法，增加

 CallbackFilter callbackFilter = new CallbackFilter();
        callbackFilter.setConfig(config);
        callbackFilter.setDefaultUrl("/starter");
        shiroFilterFactoryBean.getFilters().put("casFilter", callbackFilter);

//拦截器中增加callback的拦截

Map<String, String> filterChainDefinitionMap = new LinkedHashMap<String, String>();

filterChainDefinitionMap.put("/callback", "casFilter");

shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);

//loginUrl中需要加上clinetname

String loginUrl = casServerUrlPrefix + "/login?service=" + shiroServerUrlPrefix + "/callback?client_name=" + clientName;
shiroFilterFactoryBean.setLoginUrl(loginUrl);

4.自定义的Realm不再继承自CasRealm,修改为Pac4jRealm,并且修改其中的方法

@Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        final Pac4jToken token = (Pac4jToken) authenticationToken;
        final LinkedHashMap profiles = token.getProfiles();
        final Pac4jPrincipal principal = new Pac4jPrincipal(profiles);

        String loginName = principal.getProfile().getId();


        Session session = SecurityUtils.getSubject().getSession();
       
        session.setAttribute("userSessionId", loginName );
       

        return new SimpleAuthenticationInfo(user, profiles.hashCode(), getName());
    }

//此方法的逻辑不变，还是在此处赋请求链接权限，只是改变获取用户的方法更改一下，可以将本地查询的用户信息保存在doGetAuthenticationInfo方法中，此方法可以直接取出来

@Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
      
        //获取当前登录输入的用户名，等价于(String) principalCollection.fromRealm(getName()).iterator().next();

        Session session = SecurityUtils.getSubject().getSession();

        String loginName = (String)session.getAttribute("name");


        return info;
    }
