[大数据]spring整合redis，并使用redisTemplate

??? ? ? ? 1、导入maven依赖（?????注意：一定要保持dependency版本一致！）

????????4、测试类：

package com.wang;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Component;

/**
 * @author username
 * @date 2021/10/15 21:35
 * @description:TODO
 * @since 11
 */
@Component
public class Redis {
    @Autowired
    RedisTemplate<String,String> redisTemplate;
    public void getKey(){
        System.out.println(redisTemplate.opsForValue().get("lock"));
    }
}

????????5、junit测试

import com.wang.Hello;
import com.wang.Redis;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

/**
 * @author username
 * @date 2021/10/15 21:36
 * @description:TODO
 * @since 11
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:applicationContext.xml" })
public class TestHello {
    @Autowired Redis redis;
    @Test
    public void redisTest(){
        redis.getKey();
    }

}
