spring MVC 实战(一)

学习spring也有一段时间了,前一段时间有点事情给耽搁了一下,
现在打算捡起来继续研究(^_^).

下面把自己前一段时间做的一个简单的MVC的例子.
主要完成简单的注册功能,如果该用户名已经被注册,则跳转到fail.jsp
 否则跳转到sucees.jsp

 贴出来望大家指点一下.

配置spring   MVC

首先在 web.xml 文件中配置spring. 如下:

xml 代码

<servlet>
     <servlet-name>Dispatcherservlet-name>
     <servlet-class>
     org.springframework.web.servlet.DispatcherServlet
     servlet-class>
     <init-param>
         <param-name>contextConfigLocationparam-name>
         <param-value>/WEB-INF/applicationContext.xmlparam-value>
     init-param>
  servlet>
  <servlet-mapping>
     <servlet-name>Dispatcherservlet-name>
     <url-pattern>*.dourl-pattern>
  servlet-mapping>

  * 其中 applicationContext.xml 为spring的配置文件  ,如果有多个配置文件时

   中间用","隔开.


下面是spring的配置文件 applicationContext.xml

xml 代码
