springboot整合redis

直接上代码吧

1.首先pom中加入

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</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-test</artifactId>
        <scope>test</scope>
    </dependency>

2.然后

配置文件中

redis:
        host: 127.0.0.1
        port: 6379
        timeout: 1000
        pool:
        max-active: 8
        min-idle: 0
        max-idle: 8
        max-wait: -1

3.然后

就是类似的工具类

import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.data.redis.core.StringRedisTemplate;
    import org.springframework.data.redis.core.ValueOperations;
    import org.springframework.stereotype.Repository;
    
    @Repository
    //这个是为了标识这是个数据存储层的一个注解
    public class RedisDao {
    
        @Autowired
        private StringRedisTemplate template;
    
        public  void setKey(String key,String value){
            ValueOperations<String, String> ops = template.opsForValue();
            //ops.set(key,value,5, TimeUnit.MINUTES);//5分钟过期
            ops.set(key, value);
        }
    
        public String getValue(String key){
            ValueOperations<String, String> ops = this.template.opsForValue();
            return ops.get(key);
        }
    }

4.测试类

import com.example.demo.com.cwh.springbootRedis.dao.RedisDao;
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.test.context.SpringBootTest;
    import org.springframework.test.context.junit4.SpringRunner;
    
    
    
    @RunWith(SpringRunner.class)
    @SpringBootTest
    public class DemoApplicationTests {
    
        @Test
        public void contextLoads() {
        }
    
        public static Logger logger= LoggerFactory.getLogger(DemoApplicationTests.class);
    
        @Autowired
        RedisDao redisDao;
        @Test
        public void testRedis(){
            redisDao.setKey("name","cwh");
            redisDao.setKey("age","25");
            logger.info(redisDao.getValue("name"));
            logger.info(redisDao.getValue("age"));
            logger.info("----------------------------------");
        }
    
    }

最后你运行是不是发现报错了啊，去把本地的redis服务开了切换到redis根目录，然后用命令redis-server.exe redis.windows.conf，再运行控制台输出

cwh  
 25  
 ----------------------------------

ok!
