springboot整合redis

1.创建springboot项目 选择依赖

2.启动redis服务端 没有去官网下一个 ，傻瓜式安装（window版本）

3.在测试类中进行测试

package com.hdjy;

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 org.springframework.data.redis.core.ValueOperations;

@SpringBootTest
class NosqlRedisApplicationTests {

    @Autowired
    private RedisTemplate redisTemplate;
    @Test
    void set() {
        ValueOperations valueOperations = redisTemplate.opsForValue();
        valueOperations.set("name","sun");
    }

    @Test
    void get() {
        ValueOperations valueOperations = redisTemplate.opsForValue();
        Object name = valueOperations.get("name");
        System.out.println(name);
    }
}

执行结果

不过这种方法不能跟控制台的redis同步存取，因为控制台存入是字符串类型，RedisTemplate 是以对象的方式存入。如图

我们可以使用StringRedisTemplate解决

package com.hdjy;

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 org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.core.ValueOperations;

@SpringBootTest
class NosqlRedisApplicationTests2 {

    @Autowired
    private StringRedisTemplate redisTemplate;
    @Test
    void set() {
        ValueOperations valueOperations = redisTemplate.opsForValue();
        valueOperations.set("name","sun");
    }

    @Test
    void get() {
        ValueOperations valueOperations = redisTemplate.opsForValue();
        Object name = valueOperations.get("name");
        System.out.println(name);
    }
}

此时控制台也可以取到

如果想用jedis方式连接redis
1.引入依赖

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
</dependency>

2.配置文件中配置信息

spring:
  redis:
    host: localhost
    port: 6379
    client-type: jedis

当不配置jedis时， client-type默认是lettuce
