eclipse 使用maven 创建纯spring mvc项目

接着eclipse 使用maven 创建web3.1项目

创建完成后, 讲spring mvc加入到项目中

先修改pom.xml文件

注意红色字部分

然后编辑web.xml文件

如果安装过STS插件的话, 直接按alt + 回车



选择后就出来了, 然后改成如下

1 <?xml version="1.0" encoding="UTF-8"?>
2 <web-app
3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4 xmlns="http://xmlns.jcp.org/xml/ns/javaee"
5 xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" 6 id="WebApp_ID"
7 version="3.1">
8
9   <!-- The front controller of this Spring Web application, responsible for handling all application requests -->
10     <servlet>
11         <servlet-name>springDispatcherServlet</servlet-name>
12         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
13         <init-param>
14             <param-name>contextConfigLocation</param-name>
15             <param-value>classpath:applicationcontext.xml</param-value>
16         </init-param>
17         <load-on-startup>1</load-on-startup>
18     </servlet>
19
20     <!-- Map all requests to the DispatcherServlet for handling -->
21     <servlet-mapping>
22         <servlet-name>springDispatcherServlet</servlet-name>
23         <url-pattern>/</url-pattern>
24     </servlet-mapping>
25
26 </web-app>

红色字体部分是需要修改的,

classpath:applicationcontext.xml  文件名可以修改, 无所谓

按照如图位置创建applicationcontext.xml文件



文件内容如下

1 <?xml version="1.0" encoding="UTF-8"?>
2 <beans xmlns="http://www.springframework.org/schema/beans"
3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
4     xmlns:mvc="http://www.springframework.org/schema/mvc"
5     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd 6         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
7         http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
8
9     <!-- 设置自动扫描的包 -->
10     <context:component-scan base-package="cn.learn.*"></context:component-scan>
要在src/main/java 下创建包为cn.learn, 为了方便就这么写了, 大神别喷我

11     <!-- 开启自动注解支持 -->
12     <mvc:annotation-driven />
13     <!-- 定义静态资源位置 -->
14     <mvc:resources location="/WEB-INF/static/" mapping="/static/**"></mvc:resources>
15
16     <!-- jsp视图处理 start -->
17     <bean
18         class="org.springframework.web.servlet.view.InternalResourceViewResolver">
19         <!-- 视图前缀 -->
20         <property name="prefix" value="/WEB-INF/view/"></property>
21         <!-- 视图后缀 -->
22         <property name="suffix" value=".jsp"></property>
23         <property name="viewClass"
24             value="org.springframework.web.servlet.view.InternalResourceView" />
25         <property name="order" value="1" />
26     </bean>
27     <!-- jsp视图处理 end -->
28
29 </beans>

然后变成这样的目录结构



在cn.learn包下新建一个controller包(这一步不是必须的, 但是一般都要分开, 这东西看项目)

然后在controller包下新建一个类 IndexController

1 package cn.learn.controller;
2
3 import org.springframework.stereotype.Controller;
4 import org.springframework.web.bind.annotation.RequestMapping;
5 import org.springframework.web.servlet.ModelAndView;
6
7 @Controller
8 @RequestMapping("/index")
9 public class IndexController {
10
11     @RequestMapping("/helloword")
12     public ModelAndView hellowordAction(){
13
14         //直接返回到view目录下的 index目录下的helloword.jsp
15         return new ModelAndView("index/helloword");
16     }
17 }

新建文件 在 view/index/helloword.jsp

1 <%@ page language="java" contentType="text/html; charset=ISO-8859-1"
2     pageEncoding="ISO-8859-1"%>
3 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
4 <html>
5 <head>
6 <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
7 <title>helloword</title>
8 </head>
9 <body>
10 this is a helloword page
11 </body>
12 </html>

启动tomcat浏览器访问
http://localhost:8080/createspringmvc/index/helloword


应该注意到在applicationcontext.xml文件中配置过一个静态文件访问

<mvc:resources location="/WEB-INF/static/" mapping="/static/**"></mvc:resources>

把web应用的所有 类似于js css images 等, 不需要走框架的都放到这里

例如



写了一行 alert(1);

在浏览器中访问http://localhost:8080/createspringmvc/static/test.js



如果把这个js在页面中引用的话

在helloword.jsp页面引用<script type="text/javascript" src="${pageContext.request.contextPath}/static/test.js"></script>

再次访问http://localhost:8080/createspringmvc/index/helloword



这样就完成springmvc的最基本的可以访问了
