redis和shiro 登录session用户信息更新不成功解决方法和切面配置实例

1.redis和shiro 登录session用户信息更新不成功解决方法

public class UpdateSessionUserUtil {
    public static void setUser(LoginUserInfo loginUserInfo) {
        Subject subject = SecurityUtils.getSubject();
        PrincipalCollection principals = subject.getPrincipals();
        //realName认证信息的key，对应的value就是认证的user对象
        if (principals != null) {
            String realName = principals.getRealmNames().iterator().next();
            //创建一个PrincipalCollection对象，userInfo是更新后的user对象
            PrincipalCollection newPrincipalCollection = new SimplePrincipalCollection(loginUserInfo, realName);
            //调用subject的runAs方法，把新的PrincipalCollection放到session里面
            subject.getSession().setAttribute(DefaultSubjectContext.PRINCIPALS_SESSION_KEY, newPrincipalCollection);
        }
    }
}

2.切面配置实例

package com.cmb.biz.board.webSocket;

import core.box.shiro.UpdateSessionUserUtil;
import core.box.shiro.model.LoginUserInfo;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.session.UnknownSessionException;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.context.annotation.Configuration;

@Aspect
@Configuration
public class ServiceAspect {
//扫描方式一
    private final String ExpGetResultDataPonit = "execution(* com.cmb.biz.board.controller..*.*(..))";

    /**
    扫描方式二
     * @description 切入点
     */
    @Pointcut("@within(org.springframework.web.bind.annotation.RestController) @within(org.springframework.stereotype.Controller)")
    public void logPointCut() {

    }

    @AfterReturning(value = "logPointCut()", returning = "keys")
    public void doAfterReturningAdvice1(JoinPoint joinPoint, Object keys) {
        if (SecurityUtils.getSubject().getSession() != null) {
            try {
                Object principal = SecurityUtils.getSubject().getPrincipal();
                if (principal != null) {
                    LoginUserInfo loginUserInfo = (LoginUserInfo) principal;
                    UpdateSessionUserUtil.setUser(loginUserInfo);
                }
            } catch (UnknownSessionException e) {
                System.out.println("退出登录");
            }
        }
    }
}
