spring MVC 配置-优快云博客

本文详细介绍了如何在web.xml中配置Spring Web MVC使用自定义的contextConfigLocation参数来加载golfing-servlet.xml，并通过<mvc:annotation-driven/>确保请求能够正确映射到控制器。同时，展示了如何配置视图解析器、组件扫描以及基本的控制器实现。

web.xml 注意，因为golfing-servlet.xml并不是ContextLoaderListener默认寻找的applicationContext.xml，所以要明确指定contextConfigLocation的参数

If you don't specify the contextConfigLocation context parameter, the ContextLoaderListener will look for a file called /WEB-INF/applicationContext.xml to load.

<web-app>
<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>/WEB-INF/golfing-*.xml</param-value>
</context-param>
    <servlet>
        <servlet-name>golfing</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping> 
        <servlet-name>golfing</servlet-name>
        <url-pattern>/test/*</url-pattern>
    </servlet-mapping>

</web-app>

gofing-servlet.xml 注意：该xml名是根据web.xml的servlet-name写的

With the above servlet configuration in place, you will need to have a file called /WEB-INF/golfing-servlet.xml in your application; this file will contain all of your Spring Web MVC-specific components (beans).

<mvc:annotation-driven/>是要加的，否则无法把你请求的url转向对应的@controller.

This tag registers the DefaultAnnotationHandlerMapping and AnnotationMethodHandlerAdapter beans that are required for Spring MVC to dispatch requests to @Controllers.

    <property name="prefix" value="/WEB-INF/page/"/>
    <property name="suffix" value=".jsp"/>
</bean>
</beans>

controller,注意RequestMapping的value参数"/form"不能写成“/test/form",因为/test已经映射到DispatcherServlet

package com.yuxuan.cotroller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class BaseController {
	@RequestMapping(value="/form",method=RequestMethod.GET)
	public ModelAndView toHelloWorld(){
		return new ModelAndView("/helloworld");
	}
	
}

helloworld.jsp，该/WEB-INF/page/ 里面

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
	hello
</body>
</html>
