spring 学习jpetstore整理(-)

最近学习玩了基于spring的jpetstore的代码,把自己在学习当中的一些心得整理出来

大家可以在csdn下载漠块中,下载到有关的代码,大家利用以写好的ant build.xml进行war包的生成,放到tomcat的webapps目录下,就可运行

这个框架是基于spring+struts+ibta

那么我们首先来看web.xml的配置

 <!--
   - Loads the root application context of this web app at startup,
   - by default from "/WEB-INF/applicationContext.xml".
  - Note that it is preferable to use ContextLoaderListener in a servlet container
  - that follows the Servlet 2.4 initialization order (most Servlet 2.3 containers do).
  -
   - Use WebApplicationContextUtils.getWebApplicationContext(servletContext)
   - to access it anywhere in the web application, outside of the framework.
   -
   - The root context is the parent of all servlet-specific contexts.
   - This means that its beans are automatically available in these child contexts,
   - both for getBean(name) calls and (external) bean references.
