spring mvc 配置
一个简单的spring mvc配置实例步骤：
1.添加相关的jar包，spring.jar，jstl.jar,standard.jar
2.在com.demo1.web.controller下，新建，HelloController.java
package com.demo1.web.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
public class HelloController implements Controller {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public ModelAndView handleRequest(HttpServletRequest arg0,
HttpServletResponse arg1) throws Exception {
// TODO Auto-generated method stub
return new ModelAndView("hello", "name", name);
}
}
3.配置web.xml文件，代码如下：
<!-- 配置DispatcherServlet -->
<servlet>
<servlet-name>demo1</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
</servlet>
<!-- 配置DispatcherServlet的映射 -->
<servlet-mapping>
<servlet-name>demo1</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<jsp-config>
<jsp-property-group>
<description>demo 1</description>
<url-pattern>*.jsp</url-pattern>
<el-ignored>false</el-ignored>
<scripting-invalid>false</scripting-invalid>
</jsp-property-group>
</jsp-config>
4.在web-inf下，建立spring 的配置文件，demo1-servlet.xml,这里，demo1与web.xml中servlet-name的名字对应。代码如下：
<!-- 处理器映射器，使用处理器名字作为URL -->
<bean
class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping" />
<!-- 处理器，名字为/hello.html -->
<bean name="/hello.html"
class="com.demo1.web.controller.HelloController">
<property name="name" value="Rod Johnson" />
</bean>
<!-- 视图解析器 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
5.在web-inf下建立一个jsp目录，新建hello.jsp文件，即，spring 调用mvc控制器后，view所返回的页面，代码如下：
<body>
Hello,${name }
</body>
部署到tomcat下，一个helloworld版的spring mvc就OK了。
