一、代码
1.controller
package com.qf.controller;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.qf.pojo.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import java.util.Date;
import java.util.HashMap;
/**

*/
@RestController
public class RedisController {
@Autowired
private JedisPool jedisPool;
private ObjectMapper objectMapper = new ObjectMapper();
@RequestMapping(value = "/insert")
public HashMap<String,Object> insert() throws JsonProcessingException {
//1.获取jedis对象
Jedis jedis = jedisPool.getResource();
//2.将user对象序列化转化为json
User user = new User(1,"王大拿",new Date());
String userJson = objectMapper.writeValueAsString(user);
//3.存储到redis服务
jedis.setex("user", 1000, userJson);
HashMap<String,Object> map = new HashMap<String,Object>();
map.put("存入数据为：", user);
//4.释放资源
jedis.close();
return map;
}
@RequestMapping(value = "/select")
public HashMap<String,Object> select() throws JsonProcessingException {
//1.获取jedis对象
Jedis jedis = jedisPool.getResource();
String user = jedis.get("user");
//5.释放资源
jedis.close();
HashMap<String,Object> map = new HashMap<String,Object>();
map.put("取出数据为：",user);
return map;
}
}2.pojo
package com.qf.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import java.io.Serializable;
import java.util.Date;
@Data
@NoArgsConstructor
@AllArgsConstructor
public class User implements Serializable {
private Integer id;
private String name;
private Date birthday;
