SpringBoot——》更改Redis序列化方式
- 一、序列化方式
- 二、使用默认序列化方式
- 1、代码示例
- 2、访问接口
- 3、结果示例
- 三、更改序列化方式
- 1、代码示例
- 2、访问接口
- 3、结果示例
- 四、自定义序列化方式
一、序列化方式
- GenericJackson2JsonRedisSerializer
- GenericToStringSerializer
- Jackson2JsonRedisSerializer
- JdkSerializationRedisSerializer(默认使用)
- StringRedisSerializer
- 自定义 Serializer
二、使用默认序列化方式
1、代码示例
package com.xiaoxian.demo.controller;import com.alibaba.fastjson.JSON;
import com.xiaoxian.demo.domain.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;@RestController
public class RedisTestController {@AutowiredRedisTemplate redisTemplate;@GetMapping("/redis/test1")public void test1() {List<User> list = new ArrayList<>();User user = new User();user.setId(1);user.setName("测试");list.add(user);redisTemplate.opsForValue().set("strTest1", JSON.toJSONString(list));Map<String, Object> map = new HashMap<>(2);map.put("id", 1);map.put("name", "测试");redisTemplate.opsForHash().putAll("mapTest1", map);}
}
