*  **1.新建一个SpringBoot项目**
 *  **2.引入SpringSession依赖**

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-data-redis</artifactId>
            </dependency>
            
            <dependency>
                <groupId>org.springframework.session</groupId>
                <artifactId>spring-session-data-redis</artifactId>
            </dependency>
            <dependency>
                <groupId>org.apache.commons</groupId>
                <artifactId>commons-pool2</artifactId>
            </dependency>
            <dependency>
                <groupId>redis.clients</groupId>
                <artifactId>jedis</artifactId>
            </dependency>

*  **3.编写配置文件此处为application.properties**

server.port=8080
    ##redis配置
    spring.redis.database=1
    spring.redis.host=localhost
    spring.redis.port=6379
    spring.redis.jedis.pool.max-active=8
    spring.redis.jedis.pool.max-wait=1000
    spring.redis.jedis.pool.max-idle=8
    spring.redis.jedis.pool.min-idle=0
    ##session超时配置默认是秒
    spring.session.timeout=30

*  **3.编写接口进行测试**

package com.example.demo.sys.controller;
    
    import javax.servlet.http.HttpSession;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    import com.example.demo.sys.service.TestService;
    
    @RestController
    @RequestMapping("/")
    public class TestSessionController { 
    
    	@Autowired
    	private TestService testService;
    
    	@Value("${server.port}")
    	private Integer projectPort;
    
    	@RequestMapping("/createSession")
    	public String createSession(HttpSession httpSession, String name) { 
    		httpSession.setAttribute("name", name);
    		return "当前项目端口:[" + projectPort + "] 当前sessionId:[" + httpSession.getId() + "] 在session中存入成功！";
    	}
    
    	@RequestMapping("/getSession")
    	public String getSession(HttpSession session) { 
    		return "当前项目端口：" + projectPort + " 当前sessionId :" + session.getId() + " 获取的姓名:"
    				+ session.getAttribute("name");
    	}
    
    	@RequestMapping("/test")
    	public String test() { 
    		testService.test();
    		return "success";
    	}
    
    }

**启动多例进行测试**
