开发环境下，tomcat对热布署的支持还不够全面，致使开发人员浪费大量时间在重起服务上。为了提高开发效率，决定引入Jrebel，它对热布署的支持相对比较全面。虽然Jrebel官方号称使用它不存在内存泄漏问题，但是占用一定的资源是肯定的，因此不考虑在正式环境下使用热布署。Jrebel实际上支持非常多中间件，除了Tomcat还包括Jetty、Resin、Weblogic等等，从理论上来讲，他跟中间件也没什么关系，但实际配置的时候还是会根据中间件有所不同，具体可以上官网查看，本文要讲的是tomcat+ eclipse+ spring+ struts2+ maven的环境-Development environment, the tomcat support hot deployment is not comprehensive enough, resulting in developers wasting a lot of time in re-starting services. In order to improve development efficiency, introduction of Jrebel, deployed in support of its heat is relatively comprehensive. Jrebel official known to use it does not exist memory leak, but is sure to take some resources and therefore do not consider using hot deployment in a formal environment. Actually support very much Jrebel middleware Tomcat also includes Jetty, Resin, Weblogic, etc. theoretically speaking, he with the middleware does not matter, but the actual configuration is different according to the middleware specific can the official website to view this article talk about the tomcat+ eclipse+ spring+ struts2+ maven environment
