# Springboot简单使用RedisTemplate #

--------------------

没有在Redis的可以查看：[docker安装redis及图形化界面的使用][docker_redis]

--------------------

**1.导入依赖**：这里我主要用的是redis+mybatis-plus

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-cache</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <scope>runtime</scope>
    </dependency>
    
    <dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus-boot-starter</artifactId>
        <version>3.3.2</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>

2.在application.properties文件中配置数据源和redis相关配置

spring.datasource.url=jdbc:mysql://localhost:3306/eshop?serverTimezone=UTC&characterEncoding=UTF-8&useUnicode=true
    spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
    spring.datasource.username=root
    spring.datasource.password=123456
    
    #redis配置需要datasource数据源
    spring.redis.host=192.168.137.136
    spring.redis.port=6379

在springboot测试环境中：

//操作k-v都是字符串类型的
     @Autowired
     private StringRedisTemplate stringRedisTemplate;
     //操作k-v都是对象对象的
     @Autowired
     private RedisTemplate redisTemplate;
    
     /** * stringRedisTemplate.opsForValue() 操作字符串的 * stringRedisTemplate.opsForList() 操作列表的 * stringRedisTemplate.opsForSet() 操作集合的 * stringRedisTemplate.opsForHash() 操作散列的 * stringRedisTemplate.opsForZset() 操作有序集合的 */
     @Test
     void test01() { 
         //添加数据到redis库中
         //stringRedisTemplate.opsForValue().append("msg","helloworld1");
    
         //获得redis中的数据
         String msg = stringRedisTemplate.opsForValue().get("msg");
         System.out.println(msg);
     }

这里我用的Redis Derktop Mannger图像化界面：
