使用junit测试

package redisTest;

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.test.context.junit4.SpringRunner;

import com.Cherry.cherryPersonalWebSite.CherryPersonalWebSiteApplication;
import com.utils.RedisClusterUtil;

@RunWith(SpringRunner.class)//标识为JUnit的运行环境
@SpringBootTest(classes= CherryPersonalWebSiteApplication.class)//获取启动类、加载配置,确定装载Spring Boot;
public class RedisAutoTest {
    
    @Autowired
    private RedisClusterUtil redisClusterUtil;
    
    @Test
    public void save() {
        redisClusterUtil.set("hello", "world");
        System.out.println("设置缓存成功");
        Object res=redisClusterUtil.get("hello");
        System.out.println(""+res);
    }
}

存入成功以后去缓存中查询验证一下
keys *
get hello
到这里有的人会出现编码格式不对类似\xe5\x94\x90\xe4\xb8\
解决办法:在进入redis的时候命令后面添加--raw,它的作用有2个。
1.按数据原有格式打印数据,不展示额外的类型信息
2.显示中文
