springboot整合redis的使用，SpringBoot中如何操作Redis-蒲公英云

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

<!--集成redis-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>
 <!--连接池-->
    <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");
    }
