springboot整合redis、测试类

本地的redis得先启动

1.pom.xml：

    </dependencies>
</project>

2.配置 application.yml 文件；

空格上面的要注意

#
spring:
  profiles:
    active: abc,def
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/springboot_test
    username: root
    password: root
  redis:
    port: 6379
    host: localhost

#tomcatΪ81
server:
  port: 81

#日志记录级别
logging:
  level:
    com.itheima: debug
    org.springframework: info

# mybatis配置
mybatis:
  type-aliases-package: com.itheima.pojo
  # 映射文件路径 (一般在启动类加注解就行)
  # mapper-locations: classpath:mappers/*.xml(一般在启动类加注解就行)
  configuration:
    # 控制台输出执行sql log-impl:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

6379是本地默认redis端口，可改

3.在test包创建RedisTest.java 测试代码：

测试类

测试类都得加@RunWith(SpringRunner.class) @SpringBootTest

package com.itheima.redis;

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;

import java.util.List;
import java.util.Set;

/**
 * @author QLBF
 * @version 1.0
 * @date 2021/2/22 14:57
 */
@RunWith(SpringRunner.class)
@SpringBootTest
public class RedisTest {
    
    

    //加入java官方提供的redis测试对象
    @Autowired
    private RedisTemplate redisTemplate;

    @Test
    public void test1(){
    
    
        //1.string字符串
        // redisTemplate.opsForValue().set("str", "heima"); //一般用下面的方法
        redisTemplate.boundValueOps("str").set("喜洋洋");
        System.out.println("str="+redisTemplate.opsForValue().get("str"));

        //2.hash 散列
        redisTemplate.boundHashOps("h_key").put("name","xiaoli");
        redisTemplate.boundHashOps("h_key").put("age",18);
        //获取所有域
        Set h_key = redisTemplate.boundHashOps("h_key").keys();
        System.out.println(" hash散列的所有域：" + h_key);
        //获取所有值
        List list = redisTemplate.boundHashOps("h_key").values();
        System.out.println(" hash散列的所有域的值：" + list);

        //3.list 列表
        redisTemplate.boundListOps("l_key").leftPush("c");
        redisTemplate.boundListOps("l_key").leftPush("b");
        redisTemplate.boundListOps("l_key").leftPush("a");
        //获取全部元素
        List l_list = redisTemplate.boundListOps("l_key").range(0, -1);
        System.out.println("list列表的所有元素"+l_list);

        //4. set 集合
        redisTemplate.boundSetOps("s_key").add("a","b","c");
        Set set = redisTemplate.boundSetOps("s_key").members();
        System.out.println(" set集合中的所有元素：" + set);

        //5.sorted set 有序集合
        redisTemplate.boundZSetOps("z_key").add("a",30);
        redisTemplate.boundZSetOps("z_key").add("b",20);
        redisTemplate.boundZSetOps("z_key").add("c",25);
        Set z_set = redisTemplate.boundZSetOps("z_key").range(0, -1);
        System.out.println(" zset有序集合中的所有元素：" + z_set);
    }
}

运行这个测试类

测试成功！
