SpringBoot+Redis极简整合

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。
在这里插入图片描述

2.3 启动

打开安装目录，点击redis-server.exe即可启动。
在这里插入图片描述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。
在这里插入图片描述

3.2 application.properties

spring.redis.host=127.0.0.1
spring.redis.port=6379
spring.redis.username=
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);}
}

3.4 org/example/controller/UserController.java

这个是测试类。

package org.example.controller;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;@Controller
@RequestMapping("/user")
public class UserController {@Autowiredprotected RedisTemplate<String, String> redisTemplate;@RequestMapping(value = "/set")public Object test() {String value = "张1";redisTemplate.opsForValue().set("key1", value);return "set：" + value;}@RequestMapping(value = "/get")public Object getSMSCode() {String key1 = redisTemplate.opsForValue().get("key1");return "get：" + key1;}}

3.5 org/example/conf/RedisConf.java

这个是redis配置类。

package org.example.conf;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.StringRedisSerializer;@Configuration
public class RedisConf {@Beanpublic RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory) {RedisTemplate<String, String> redisTemplate = new RedisTemplate<>();redisTemplate.setConnectionFactory(factory);// redisTemplate 的默认序列化方式为 jdkSerializeable,// StringRedisTemplate的默认序列化方式为StringRedisSerializerStringRedisSerializer stringRedisSerializer = new StringRedisSerializer();// key序列化方式redisTemplate.setKeySerializer(stringRedisSerializer);// hash key序列化方式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;}}
