redis實作session共享

配置相關maven依賴

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-redis</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-data-redis</artifactId>
</dependency>

</dependency>
           

在主啟動類上開啟@EnableRedisHttpSession

package com.zr.aop;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;

@SpringBootApplication
@EnableRedisHttpSession
public class AopApplication {

    public static void main(String[] args) {
        SpringApplication.run(AopApplication.class, args);
    }

}
           

配置properties檔案

application-dev.properties

server.port=8080
           

application-test.properties

server.port=8081
           

測試

package com.zr.aop.controller;

import com.zr.aop.pojo.User;
import org.springframework.http.HttpRequest;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.HashMap;
import java.util.Map;

@RestController
public class RedisSessionShare {
    @GetMapping("/set")
    public Map<String, User> setSession(HttpServletRequest request, HttpServletResponse response){
        Map<String,User> map = new HashMap<>();
        User user = new User("1", "David", 12);
        request.getSession().setAttribute("user", user);
        map.put("user",user );
        return map;
    }

    @GetMapping("/get")
    public Object getSession(HttpServletRequest request){
        String id = request.getSession().getId();
        Map<String,Object> map = new HashMap<>();
        map.put("sessionID",id);
        map.put("user",request.getSession().getAttribute("user"));
        return map;
    }

}
