SpringBoot 项目 添加 redis配置
一、新建一个springboot 项目，springboot项目创建过程详见：传送门
二、pom.xml依赖配置
org.springframework.boot
spring-boot-starter-data-redis
三、application.yml 配置
spring:
# redis配置
redis:
# 地址
host: 127.0.0.1
# 端口，默认为6379
port: 6379
# 连接超时时间
timeout: 10s四、增加RedisConfig.java启动加载类

五、验证
package com.prison.test;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.test.context.junit4.SpringRunner;
@SpringBootTest
@RunWith(SpringRunner.class)
public class RedisTest {
@Autowired
private RedisTemplate redisTemplate;
@Test
public void redis(){
redisTemplate.boundValueOps("name").set("hahahah");
System.out.println( redisTemplate.boundValueOps("name").get());
}
}
