目录结构如下：
application.properties配置文件（redis的配置）：
spring.redis.host=localhost
spring.redis.pool.max-idle=300
spring.redis.pool.max-wait=3000
spring.redis.timeout=3000
spring.redis.port=6379SbootInitializer.java文件 :
该类的作用是为了让spingboot项目可以从我的tomcat服务器启动
package com.sboot.boot;import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;import com.sboot.builder.SbootBuilder;/*** 用于从外部容器启动* * @author * @version [版本号, 2017年12月21日]* @see [相关类/方法]* @since [产品/模块版本]*/
public class SbootInitializer extends SpringBootServletInitializer {@Overrideprotected SpringApplicationBuilder configure(SpringApplicationBuilder application) {return application.sources(SbootBuilder.class);}
}
SbootBuilder.java文件
package com.sboot.builder;import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.ComponentScans;/*** 工程组建类* * @author * @version [版本号, 2017年12月21日]* @see [相关类/方法]* @since [产品/模块版本]*/
@SpringBootApplication
//扫描包，使类中的注解组建生效
@ComponentScan(value = {"com.sboot"})
public class SbootBuilder {}
RedisConfig.java 文件
package com.sboot.redis;import java.util.ArrayList;
import java.util.List;import org.springframework.beans.factory.ObjectProvider;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.data.redis.RedisAutoConfiguration;

} RedisKeyListener.java 文件
package com.sboot.redis;import org.springframework.data.redis.connection.Message;
import org.springframework.data.redis.connection.MessageListener;/*** <一句话功能简述>* <功能详细描述>* * @version [版本号, 2017年12月29日]* @see [相关类/方法]* @since [产品/模块版本]*/
public class RedisKeyListener implements MessageListener{/***当0号库和1号库中的键发生相关改动该函数会被出发* @param message* @param pattern*/@Overridepublic void onMessage(Message message, byte[] pattern) {// TODO Auto-generated method stubSystem.out.println("********hasdfasdf***********");}}

最后修改redis的配置文件
# K Keyspace events, published with __keyspace@<db>__ prefix.
# E Keyevent events, published with __keyevent@<db>__ prefix.
# g Generic commands (non-type specific) like DEL, EXPIRE, RENAME, ...
# $ String commands
# l List commands
# s Set commands
# h Hash commands
# z Sorted set commands
# x Expired events (events generated every time a key expires)
# e Evicted events (events generated when a key is evicted for maxmemory)
# A Alias for g$lshzxe, so that the "AKE" string means all the events.
#
# The "notify-keyspace-events" takes as argument a string that is composed
# of zero or multiple characters. The empty string means that notifications
# are disabled.
#
# Example: to enable list and generic events, from the point of view of the
# event name, use:
#
# notify-keyspace-events Elg
#
# Example 2: to get the stream of the expired keys subscribing to channel
# name __keyevent@0__:expired use:
#
# notify-keyspace-events Ex
#
# By default all notifications are disabled because most users don't need
# this feature and the feature has some overhead. Note that if you don't
# specify at least one of K or E, no events will be delivered.
#notify-keyspace-events ""
notify-keyspace-events Eg$
