1. 添加依赖
在项目中添加session依赖和redis依赖如下所示 dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-data-redis/artifactId/dependencydependencygroupIdorg.springframework.session/groupIdartifactIdspring-session-data-redis/artifactId/dependency2. 配置redis连接信息
# redis连接配置信息
spring.redis.host124.221.76.124
# 不写默认wei6379数据库为0
# spring.redis.database15
spring.redis.port6379# 配置session连接信息
spring.session.store-typeredis
server.servlet.session.timeout1800
spring.session.redis.flush-modeon_save
spring.session.redis.namespacespring:session
3. 存储和读取session从Redis package com.example.sp_redis.controller;import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;/*** 实现session持久化* author zq* date 2023-07-26 14:37*/RestController
public class UserController {private static final String SESS_USER_KEY SESS_USER_KEY;RequestMapping(/login)public String login(HttpSession httpSession) {//存入sessionhttpSession.setAttribute(SESS_USER_KEY, wangwu);return Session set success.;}RequestMapping(/getuser)public String getUser(HttpServletRequest request) {String user NULL;HttpSession session request.getSession(false);if (session ! null) {//从redis中获取sessionObject userObj session.getAttribute(SESS_USER_KEY);if (userObj ! null) {user userObj.toString();}}return user;}
}
我们访问localhost:8080/login 将session存入redis
接着访问localhost:8080/login可以读取到缓存中的数据 接着我们可以在redis客户端看到存入到session
