spring mvc 项目配置

本文介绍的spring mvc 项目配置要达到的目标是当访问网站静态资源的时候直接返回。

本项目视图选择原始的HTML，使用ajax访问后台控制器。

1、首先在src下面创建controller包，主要用来放控制器，看名字就知道了。

2、在网站根目录下面（web）创建static文件夹，主要是用来放静态文件（html，css，js，image等）。

3、web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1">
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>

4、applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <context:component-scan base-package="controller"></context:component-scan>
<mvc:annotation-driven></mvc:annotation-driven>
<mvc:resources mapping="/static/**" location="/static/"/>
</beans>

5、dispatcher-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <context:component-scan base-package="controller"></context:component-scan>
<mvc:annotation-driven></mvc:annotation-driven>
<mvc:resources mapping="/static/**" location="/static/"/>
</beans>

6、在controller下面添加 root.java 文件，指定一下访问网站跟目录时要打开那一个页面。当用户访问http://localhost:8080/ 或者 http://localhost:8080/index 时会打开index.html。

package controller;

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

/**
* Created by zhengjiang on 2016/2/18.
*/
//标记为控制器，控制器URL前缀是：/。
@Controller
@RequestMapping("/")
public class root {
//标记该action的访问路径
@RequestMapping("/")
public Object start()
{
return "/static/index.html";
}

@RequestMapping("/index")
public Object index(){ return "/static/index.html";}
}

7、在static下创建名为index的HTML文件，在页面输入Holle Word，点击运行看效果，你就可以看到你亲爱的Holle Word了。
