SpringBoot整合redis（lettuce）

• pom文件导入依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

• application.yml配置

server:
  port: 8823
spring:
  #redis 要放在spring里，和datasourece同级
  redis:
    host: 127.0.0.1
    port: 6379
    password: 123456
    timeout: 3000
  datasource:
    username: root
    password: root
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/hellomybatis?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8

#整合mybatis
mybatis:
  type-aliases-package: com.example.batis.entity
  mapper-locations:
    - classpath:mybatis/mapper/*.xml

• Demo

package com.example.batis;

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;
import java.sql.SQLException;

@SpringBootTest
class BatisApplicationTests {

	@Autowired
	private RedisTemplate redisTemplate;

	@Test
	void contextLoads() throws SQLException {

        //redisTemplate  操作不同的数据类型，api和指令相同
        //opsForValue()  操作字符串 类似String
        //opsForList 	 操作List  类似List
        //opsForSet
        //opsForHash
        ·······
        //除了基本的操作，常用的方法都可以直接通过redisTemplate操作，如事务和基本的增删改查
		redisTemplate.opsForValue().set("key","value");
        
        //获取redis的连接对象（较少用）
        RedisConnection connection = redisTemplate.getConnectionFactory().getConnection();
		connection.flushDb();
		connection.flushAll();

        
        
	}

}

• 关闭redis的时候要用redis-cli.exe shutdown，暴力关闭redis数据会丢失
