# 一 搭建工程 #

1.  添加依赖，贴上pom文件

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

                </plugin>
            </plugins>
        </build>
    
    </project>

1.  启动redis服务器，然后在项目配置文件添加以下内容

spring:
      redis:
        host: 127.0.0.1
        port: 6379
        password:

1.  贴上启动类

@SpringBootApplication
    @EnableCaching
    @EnableRedisHttpSession
    @RestController
    public class RedisSessionApplication { 
    
        @Autowired
        private HttpSession session;
    
        public static void main(String[] args) { 
            SpringApplication.run(RedisSessionApplication.class, args);
        }
    
        @GetMapping("/user/add")
        public String addUser() { 
            session.setAttribute("user", "Jack");
            return "add Jack success !";
        }
    
        @GetMapping("/user/q")
        public String getUser() { 
            Object user = session.getAttribute("user");
            return String.format("get %s from session success !",String.valueOf(user));
        }
    }

# 二 测试 #

1.  启动项目，访问：[http://localhost:8080/user/add][http_localhost_8080_user_add]  
    ![在这里插入图片描述][2019072910001985.png]
2.  访问：[http://localhost:8080/user/q][http_localhost_8080_user_q]  
    ![在这里插入图片描述][20190729100111580.png]
3.  重启工程，直接访问：[http://localhost:8080/user/q][http_localhost_8080_user_q]  
    ![在这里插入图片描述][20190729100325733.png]  
    *依然获取到了session结果，证明session是保存在redis中了*
4.  贴上redis服务器保存session的截图
