springboot整合redis的使用，SpringBoot中如何操作Redis

#### 一、先创建springboot项目，然后添加相关POM依赖 ####

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

#### 二、配置连接redis的application.yml文件 ####

spring:
      redis:
        host: 127.0.0.1
        port: 6379
    server:
      port: 8083
    
    //连接池
    spring.redis.lettuce.pool.min-idle=5
    spring.redis.lettuce.pool.max-idle=10
    spring.redis.lettuce.pool.max-active=8
    spring.redis.lettuce.pool.max-wait=1ms
    spring.redis.lettuce.shutdown-timeout=100ms

#### 三、启动redis并连接 ####

3.1 进入到安装redis的目录下

3.2 使用命令启动并去连接

**四、测试连接：做一个基本的连接测试**

package cn.tedu.controller;
     
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.data.redis.core.StringRedisTemplate;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
     
    /**
     * @Classname RedisController
     */
    @RestController
    @RequestMapping("/redis")
    public class RedisController {
        @Autowired
        private StringRedisTemplate template;
        @GetMapping("/hello")
        public String hello(String name,String age){
          template.opsForValue().set(name,age);
            String value = template.opsForValue().get(name);
            System.out.println(name+","+value);
            return name+","+value;
        }
    }

#### 五、通过对象的方式来进行数据的保存与读取。在项目中新增一个User类 ####

package cn.tedu.pojo;
     
    import lombok.Data;
    import lombok.experimental.Accessors;
     
    /**
     * @Classname User
     */
    @Data
    @Accessors(chain = true)
    public class User {
        private String name;
        private Integer age;
        private String Gender;
    }

@GetMapping("/user")
        public String getUser(){
            List<User> userList = new ArrayList<>();
            userList.add(new User().setName("小李头").setAge(23).setGender("女"));
            userList.add(new User().setName("小白").setAge(20).setGender("男"));
            userList.add(new User().setName("张三").setAge(30).setGender("男"));
            userList.add(new User().setName("小法师").setAge(15).setGender("女"));
            template.opsForValue().set("user", String.valueOf(userList));
            System.out.println(template.opsForValue().get("user"));
            return template.opsForValue().get("user");
        }
