整合shiro以及将session存入reids中，导入shiro-redis包，就不用自己实现怎么往redis中存session了。现在一般都是前后端分离的项目，后台返回统一的格式给前端

shiro配置类，很重要

为了避免session频繁从redis中读取，要重写方法

package com.pwl.shiro.config;

import org.apache.shiro.session.Session;

import org.apache.shiro.session.UnknownSessionException;

import org.apache.shiro.session.mgt.SessionKey;

import org.apache.shiro.web.session.mgt.DefaultWebSessionManager;

import javax.servlet.ServletRequest;

import java.io.Serializable;

/**

* @author Pan Weilong

* @date 2019/6/22 10:40

* @description: 接口.

*/

public class ShiroSessionManager extends DefaultWebSessionManager {

@Override

protected Session retrieveSession(SessionKey sessionKey) throws UnknownSessionException {

Serializable sessionId = getSessionId(sessionKey);

ServletRequest request = null;

if (sessionKey instanceof WebSessionKey) {

request = ((WebSessionKey) sessionKey).getServletRequest();

}

if (request != null && null != sessionId) {

Object sessionObj = request.getAttribute(sessionId.toString());

if (sessionObj != null) {

return (Session) sessionObj;

}

}

Session session = super.retrieveSession(sessionKey);

if (request != null && null != sessionId) {

request.setAttribute(sessionId.toString(), session);

}

return session;

}

}

统一异常处理类

package com.pwl.shiro.exception;

import com.pwl.shiro.common.ResultVO;

import org.apache.shiro.authz.UnauthenticatedException;

import org.apache.shiro.authz.UnauthorizedException;

@Override

返回统一的格式

首次登陆的时候

然后登陆

最后访问需要某些权限的接口

当用户没有权限的时候访问接口
