注意:spring boot 1.5和2.0是一个大变动，如果是1.5版本的只需要导入redis启动器就可以运行，而2.0不允许

2 application.yml

spring:
    redis:
      #数据库索引
      database: 0
      host: 120.78.150.135
      port: 6379
      password: 123456
      jedis:
        pool:
          #最大连接数
          max-active: 8
          #最大阻塞等待时间(负数表示没限制)
          max-wait: -1
          #最大空闲
          max-idle: 8
          #最小空闲
          min-idle: 0
      #连接超时时间
      timeout: 10000

3.redis配置

package com.cloudtech.config;
 
import java.util.concurrent.CountDownLatch;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.listener.PatternTopic;
import org.springframework.data.redis.listener.RedisMessageListenerContainer;
import org.springframework.data.redis.listener.adapter.MessageListenerAdapter;
 
/**
 * 
* @ClassName: RedisConfig  
* @Description:   
* @author wude  
* @date 2018年12月13日  
*
 */
@Configuration
@EnableCaching   //加入缓存
public class RedisConfig extends CachingConfigurerSupport {
	
	@Bean
	RedisMessageListenerContainer container(RedisConnectionFactory connectionFactory,
			MessageListenerAdapter listenerAdapter) {
 
		RedisMessageListenerContainer container = new RedisMessageListenerContainer();
		container.setConnectionFactory(connectionFactory);
		container.addMessageListener(listenerAdapter, new PatternTopic("chat"));
 
		return container;
	}
 
	@Bean
	MessageListenerAdapter listenerAdapter(Receiver receiver) {
		return new MessageListenerAdapter(receiver, "receiveMessage");
	}
 
	@Bean
	Receiver receiver(CountDownLatch latch) {
		return new Receiver(latch);
	}
 
	@Bean
	CountDownLatch latch() {
		return new CountDownLatch(1);
	}
 
	@Bean
	StringRedisTemplate template(RedisConnectionFactory connectionFactory) {
		return new StringRedisTemplate(connectionFactory);
	}
	
	public class Receiver { 
		
 
		private CountDownLatch latch;
		
		@Autowired
		public Receiver(CountDownLatch latch) {
		    this.latch = latch;
		}
		
		public void receiveMessage(String message) {
		    latch.countDown();
		}
	}
	
	
}

4.单元测试

关于springboot进行单元测试不了解的，可以查看  https://blog.csdn.net/qq_16855077/article/details/84973919

package com.cloudtech.test;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.cloudtech.App2;
import com.cloudtech.entity.Role;
import com.cloudtech.service.RoleService;

/**
 * spring 测试类
 * @RunWith:启动器
 * SpringJUnit4ClassRunner  让junit和spring环境进行整合
 * @SpringBootTest  1.当前类为spring的测试类   2加载spring boot启动类，启动spring boots
 * 
* @ClassName: RoleTest  
* @Description:   
* @author wude  
* @date 2018年12月12日  
*
 */
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes={App2.class})
public class RoleTest {
	
	@Autowired
	private StringRedisTemplate template;
	
	
	
	@Test
	public void test2(){
		template.opsForValue().append("shabao", "我是帅锅,哈哈哈哈哈");
	}
}

4.测试

这里使用到redis可视化工具 https://blog.csdn.net/qq_16855077/article/details/84985655
