MyEclipse中spring MVC的配置

---恢复内容开始---

web.xml配置：

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	xmlns="http://java.sun.com/xml/ns/javaee"

	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

        http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"

	id="WebApp_ID" version="3.0">

	<display-name>Face</display-name>

	<welcome-file-list>

		<welcome-file>index.html</welcome-file>

		<welcome-file>index.htm</welcome-file>

		<welcome-file>index.jsp</welcome-file>

		<welcome-file>default.html</welcome-file>

		<welcome-file>default.htm</welcome-file>

		<welcome-file>default.jsp</welcome-file>

	</welcome-file-list>

	<servlet>

                <!--servlet名称无关紧要-->

		<servlet-name>springMvc</servlet-name>

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

                <!--init-param为servlet的参数初始化，这里用来初始化servlet配置文件的路径-->

		<init-param>

			<param-name>contextConfigLocation</param-name>

			<param-value>/WEB-INF/applicationContext.xml</param-value>

		</init-param>

	</servlet>

	<servlet-mapping>

		<servlet-name>springMvc</servlet-name>

		<url-pattern>/</url-pattern>

	</servlet-mapping>

</web-app>

　　servlet配置文件(applicationContext.xml):

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
　　<!--添加下面这条context名称空间-->

   xmlns:context="http://www.springframework.org/schema/context"

   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

   xsi:schemaLocation="

       http://www.springframework.org/schema/beans

       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

       http://www.springframework.org/schema/context

       http://www.springframework.org/schema/context/spring-context-3.0.xsd">

  　<!--扫描的包-->

    <context:component-scan base-package="你的包名" />  

    <bean

        class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <property name="prefix">

                        <!-- 这个配置是配置JSP页面的路径，按照你自己的配置来配 -->

            <value>/WEB-INF/jsp/</value>

        </property>

        <property name="suffix">

            <value>.jsp</value>

        </property>

    </bean>  

</beans>

　　在相应包中建一个java文件进行测试：

package 包名;

import org.springframework.stereotype.Controller;

import org.springframework.ui.ModelMap;

import org.springframework.web.bind.annotation.RequestMapping;

@Controller

@RequestMapping("/hello")

public class TestHello{

	@RequestMapping("mvc")

	public String printWelcome(ModelMap model){

		return "hello"; //表示返回hello.jsp模板

	}

}

　　hello.jsp：

<body>

    Hello. <br>

  </body>
