SpringBoot整合Redis

1、创建springboot工程

2、添加依赖

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>3.0.5</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>

3、创建配置文件

spring:
  data:
    redis:
      host: 192.168.74.148
      port: 6379

4、创建启动类

package com.atguigu.springboot.redis;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;


// Generated by https://start.springboot.io
// 优质的 spring/boot/data/security/cloud 框架中文文档尽在 => https://springdoc.cn
@SpringBootApplication
public class SpringbootRedisApplication {

	public static void main(String[] args) {
		SpringApplication.run(SpringbootRedisApplication.class, args);
	}

}

5、创建测试类，编写测试方法

package com.atguigu.springboot.redis;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.RedisTemplate;

@SpringBootTest
class SpringbootRedisApplicationTests {
	@Autowired
	private RedisTemplate redisTemplate;

	@Test
	void contextLoads() {
		redisTemplate.opsForValue().set("hello", "world");
	}

}

127.0.0.1:6379> select 0
OK
127.0.0.1:6379> keys *
1) "\xac\xed\x00\x05t\x00\x05hello"
127.0.0.1:6379> get "\xac\xed\x00\x05t\x00\x05hello"
"\xac\xed\x00\x05t\x00\x05world"
127.0.0.1:6379>

6、序列化定制

package com.atguigu.springboot.redis;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
@Configuration
public class AppRedisConfiguration {

    @Bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<Object, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);
        //把对象转为json字符串的序列化工具
        template.setDefaultSerializer(new GenericJackson2JsonRedisSerializer());
        return template;
    }
}

此时再执行一下测试类SpringbootRedisApplicationTests，乱码问题就得到解决

127.0.0.1:6379> keys *
1) "\xac\xed\x00\x05t\x00\x05hello"
2) "\"hello\""
127.0.0.1:6379> get "\"hello\""
"\"world\""
127.0.0.1:6379>
