1 前言
Redis是现在最受欢迎的NoSQL数据库之一,下面将以最简洁的代码演示,在SpringBoot中使用redis。
2 下载安装Redis
2.1 下载
Redis3.x windows安装版下载地址
2.2 安装到任意位置
一直Next到完即可。
 
2.3 启动
打开安装目录,点击redis-server.exe即可启动。
 
启动成功会弹出命令行,可以看到端口默认是6379。
 
3 代码
创建一个名为spring-boot-redis-demo的项目,使用Maven+JDK17。不会的请看 IntelliJ IDEA快速创建Spring Boot项目,最终项目结构,如下图。

spring.redis.password=
 
3.3 org/example/Main.java
package org.example;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
@SpringBootApplication
public class Main extends SpringBootServletInitializer {
    public static void main(String[] args) {
        SpringApplication.run(Main.class, args);

		redisTemplate.setHashKeySerializer(stringRedisSerializer);
		// value序列化方式
		redisTemplate.setValueSerializer(stringRedisSerializer);
		// hash value序列化方式
		redisTemplate.setHashValueSerializer(stringRedisSerializer);
		// 支持事物
		redisTemplate.setEnableTransactionSupport(false);
		redisTemplate.afterPropertiesSet();
		return redisTemplate;
	}
}
 
4 测试
- 启动项目,打开浏览器访问http://localhost:8080/user/set,set数据。
 

 2. 启动项目,打开浏览器访问http://localhost:8080/user/get,get数据。
