数据源配置

application.properties

spring.redis.host=localhost
spring.redis.port=6379
spring.redis.password=
spring.redis.database=1
spring.redis.pool.max-active=20
spring.redis.pool.max-wait=-1
spring.redis.pool.max-idle=500
spring.redis.pool.min-idle=5
spring.redis.timeout=0

具体实现代码

RedisDao：

package com.cwh.springbootRedis.dao;

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
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);
    }
}

Application：

package com.cwh.springbootRedis;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

	public static void main(String[] args) {
		SpringApplication.run(Application.class, args);
	}
}

DemoTest：

package com.cwh.springbootRedis.test;

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;

import com.cwh.springbootRedis.dao.RedisDao;

@RunWith(SpringRunner.class)
@SpringBootTest
public class DemoTest {

	 	public static Logger logger= LoggerFactory.getLogger(DemoTest.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"));
	    }
}

运行测试

打印如下信息

cwh
25
