# 1.环境搭建 #

我们还是继续用在初学Redis(四)中使用的项目

## 1.1替换pom依赖 ##

<dependencies>
            
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-data-redis</artifactId>
                <version>2.1.4.RELEASE</version>
            </dependency>
            <dependency>
                <groupId>redis.clients</groupId>
                <artifactId>jedis</artifactId>
                <version>2.9.0</version>
            </dependency>
            
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <version>2.2.4.RELEASE</version>
            </dependency>
        </dependencies>

## 1.2 创建application.yml文件 ##

![up-bfb6c19fb814caabd8f2417b081af98d73e.png][]

spring:
      redis:
        host: 127.0.0.1 #redis服务地址
        database: 0     #确定使用库
        port: 6379      #redis 端口号

## 1.3 创建启动类 ##

![up-582f4aa4448545bc62e81f40ce6eaa257a9.png][]

package com.manlu;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    /**
     * @Auther 漫路h
     * Created by 2020-04-27 11:38
     */
    @SpringBootApplication
    public class TestRedisApplication {
        public static void main(String[] args) {
            SpringApplication.run(TestRedisApplication.class,args);
        }
    }

## 1.4 整合Junit ##

![up-64bae89353b5a7b80b4895c4fdca27e9927.png][]

package com.manlu;
    
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.boot.test.context.SpringBootTest;
    import org.springframework.data.redis.core.StringRedisTemplate;
    import org.springframework.test.context.junit4.SpringRunner;
    
    import javax.annotation.Resource;
    
    /**
     * @Auther 漫路h
     * Created by 2020-04-27 11:40
     */
    @RunWith(SpringRunner.class)
    @SpringBootTest(classes = TestRedisApplication.class)
    public class TestRedisTemplate {
        @Resource
        private StringRedisTemplate stringRedisTemplate;
    
        @Test
        public void demo01(){
            System.out.println(stringRedisTemplate);
        }
    }

# 2. StringRedisTemplate常用方法 #

Redis 一共有5种类型，StringRedisTemplate提供对5种类型操作。

<table> 
 <thead> 
  <tr> 
   <th>方法</th> 
   <th>描述</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>opsForValue()</td> 
   <td>操作字符串</td> 
  </tr> 
  <tr> 
   <td>delete(key)</td> 
   <td>根据key删除数据</td> 
  </tr> 
  <tr> 
   <td>opsForHash()</td> 
   <td>操作hash</td> 
  </tr> 
  <tr> 
   <td>opsForList()</td> 
   <td>操作list</td> 
  </tr> 
  <tr> 
   <td>opsForSet()</td> 
   <td>操作set</td> 
  </tr> 
  <tr> 
   <td>opsForZSet()</td> 
   <td>操作有序set</td> 
  </tr> 
 </tbody> 
</table>

## 2.1 opsForValue()操作 ##

<table> 
 <thead> 
  <tr> 
   <th>方法</th> 
   <th>描述</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>ops.set(key,value)</td> 
   <td>向redis中插入数据。永久存储</td> 
  </tr> 
  <tr> 
   <td>ops.set(key,value,time,timeUtil)</td> 
   <td>向redis中插入数据，参数3是一个long的时间，参数4是时间的单位。</td> 
  </tr> 
  <tr> 
   <td>ops.get(key)</td> 
   <td>获取redis中指定key的value值</td> 
  </tr> 
 </tbody> 
</table>

## 2.2 测试类 ##

### 2.2.1 添加字符串 ###

/**
         * 添加字符串数据
         */
        @Test
        public void demo01(){
            stringRedisTemplate.opsForValue().set("demo01","我是demo01");
        }

执行完成后看可视化工具

![up-b11f918d3c0b2fe94355b53b5e9a07a896b.png][]

### 2.2.2 添加字符串(有效时间) ###

/**
         * 添加字符串数据(有效时间)
         */
        @Test
        public void demo02(){
            stringRedisTemplate.opsForValue().set("demo02","我是demo02",1, TimeUnit.MINUTES);
        }

执行完成后看可视化工具

![up-9c6c4ff3f8cc11d4170e15c38896ecdfd32.png][]

### 2.2.3 获取字符串 ###

/**
         * 获取字符串
         */
        @Test
        public void demo03(){
            String str = stringRedisTemplate.opsForValue().get("demo01");
            System.out.println(str);
        }

看执行结果

### 2.2.4 删除指定key ###

/**
         * 删除指定的key
         */
        @Test
        public void demo04(){
            Boolean b = stringRedisTemplate.delete("demo01");
            System.out.println(b);
        }

执行完成后看可视化工具
