SpringMVC

第一个简单案例：

1）     建一个Web工程

2）     在web.xml中配置

<servlet>

    <servlet-name>springMVC</servlet-name>

    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

    <load-on-startup>1</load-on-startup>

 </servlet>

 <servlet-mapping>

    <servlet-name>springMVC</servlet-name>

    <url-pattern>/</url-pattern>

 </servlet-mapping>

3）     在web-inf下建一个springMVC-servlet.xml文件，配置：

<beanid="viewResolver"class="org.springframework.web.servlet.view.InternalResourceViewResolver">

       <propertyname="prefix"value="/"></property>

       <propertyname="suffix"value=".jsp"></property>

</bean>

4）     建一个HelloController并且继承Controller的class

packagecontroller;

importjavax.servlet.http.HttpServletRequest;

importjavax.servlet.http.HttpServletResponse;

importorg.springframework.web.servlet.ModelAndView;

importorg.springframework.web.servlet.mvc.Controller;

publicclass HelloController implements Controller {

public ModelAndViewhandleRequest(HttpServletRequest arg0,

      HttpServletResponse arg1) throws Exception{

    System.out.println("hello this is firsttest");

    return new ModelAndView("hello");

}

}

5）     然后springMVC-servlet.xml中配置

<beanname="/test/hello"class="controller.HelloController"></bean>

6）      编写hello.jsp页面

最后就可以启动Tomcat，通过项目名加上test/hello访问Hellocontroller并且跳转到helo.jsp
