spring+websocket整合

java-websocket的搭建非常之容易,没用框架的童鞋可以在这里下载撸主亲自调教好的java-websocket程序:

Apach Tomcat 8.0.3+MyEclipse+maven+JDK1.7

http://download.csdn.net/detail/up19910522/7719087

 

spring4.0以后加入了对websocket技术的支持,撸主目前的项目用的是SSM(springMVC+spring+MyBatis)框

架,所以肯定要首选spring自带的websocket了,好,现在问题来了,撸主在网上各种狂搜猛找,拼凑了几个自称是

spring websocket的东东,下来一看,废物,其中包括从github上down下来的。举个例子,在搭建过程中有个问题,

撸主上谷歌搜索,总共搜出来三页结果共30条左右,前15条是纯英文的  后15条是韩语和日语,而这30条结果都不能

解决撸主的问题,无奈,只好上官网看全英帮助,在撸主惊人的毅力和不懈奋斗下,纠结了两天的spring+websocket

整合今天算是彻底搭建成功,摸索透彻了。

websocket是目前唯一真正实现全双工通信的服务器向客户端推的互联网技术,与长连接和轮询技术相比,

websocket的优越性不言自明,长连接的连接资源(线程资源)随着连接数量的增多,必会耗尽,客户端轮询会给服

务器造成很大的压力,而websocket是在物理层非网络层建立一条客户端至服务器的长连接,以此来保证服务器向客

户端的即时推送,既不耗费线程资源,又不会不断向服务器轮询请求。

下面言归正传,讲一讲撸主在SSM(springMVC+spring+MyBatis)框架中集成websocket技术的曲折蛋疼直至成功喜悦之路。

 

  • 1 在maven的pom.xml中加入websocket所依赖的jar包,什么,你不知道maven,快去度之或者查看撸主关于maven的博文恶补一下,spring-websocket所依赖的jar包有以下几个:
