用java代码操作Redis进行相关的Hash，String,Set,List操作

Posted 2021-09-05 SmallCuteMonkey

使用SpringBoot的测试来实现这些相关的操作：

1. 需要注入RedisTemplate模板来实现相关的操作。

 @Autowired
    private RedisTemplate<String,String> redisTemplate;

2. 通过实现它的封装的常用的方法进行相关的实现。
3. 实现的方法有：

  redisTemplate.boundHashOps("tvs").put("cctv","中央电视台");
   Set tvs = redisTemplate.boundHashOps("tvs").keys();
     List tvs = redisTemplate.boundHashOps("tvs").values();
        String string= (String)redisTemplate.boundHashOps("tvs").get("hntv");
//        size
        Long size= redisTemplate.boundHashOps("tvs").size();
        System.out.println("hash集合的大小" + size);
      
//List
  redisTemplate.boundListOps("sbootList").leftPush("dd");
        redisTemplate.boundListOps("sbootList").rightPush("11");
        //        range 0，-1为List查询 所有
        List<String> sbootList = redisTemplate.boundListOps("sbootList").range(0, -1);
//        表示把bb删除两个
        redisTemplate.boundListOps("sbootList").remove(2,"bb");
        //list set修改 1相当于修改第二个值
 redisTemplate.boundListOps("sbootList").set(1,"me");

比如String类：

  @Test
    public void test(){
           redisTemplate.boundValueOps("str").set("诸葛亮");
    }
    @Test
    public void testGetValue(){
        String address = redisTemplate.boundValueOps("address").get();
        System.out.println(address);


    }

pom.xml文件的引入：

        <artifactId>spring-boot-starter-parent</artifactId>
        <groupId>org.springframework.boot</groupId>

TestHash测试类：

package test;

import org.junit.Test;
import org.junit.runner.RunWith;

@SpringBootTest(classes = StuApplication.class)
public class TestHash {

    @Autowired
    private RedisTemplate redisTemplate;
    @Test
    public void test(){

        redisTemplate.boundHashOps("tvs").put("cctv","中央电视台");
        redisTemplate.boundHashOps("tvs").put("hntv","湖南电视台");
        redisTemplate.boundHashOps("tvs").put("bjtv","北京电视台");

    }

//    查询所有的key

    @Test

    public void test1(){
        Set tvs = redisTemplate.boundHashOps("tvs").keys();
        System.out.println(tvs);

    }
//    获取所有的values
    @Test

    public void test2(){
        List tvs = redisTemplate.boundHashOps("tvs").values();
        System.out.println(tvs);

    }

//    获取单个的值
    @Test

    public void test3(){
        String string= (String)redisTemplate.boundHashOps("tvs").get("hntv");
//        size
        Long size= redisTemplate.boundHashOps("tvs").size();
        System.out.println("hash集合的大小" + size);

        System.out.println("hntv的值"+string);

    }
//    删除单个

    @Test

    public void test4(){
        Long del = redisTemplate.boundHashOps("tvs").delete("cctv");
        Long size = redisTemplate.boundHashOps("tvs").size();

        System.out.println(del + size);

    @Test
//list set修改 1相当于修改第二个值

//    删除
    @Test

    public void test3(){
//        表示把bb删除两个
        redisTemplate.boundListOps("sbootList").remove(2,"bb");

    }

//    集合查询单个

    @Test

    public void test4(){

        Long size = redisTemplate.boundListOps("sbootList").size();
