eclipse maven创建web项目

创建SSM整合项目

一.使用Eclipse中的maven插件创建web项目

　　　2：

　　　　5:maven web项目创建成功。（去掉index.jsp文件重新创建jsp文件，报错消失）

　　8.Eclipse创建一个动态web项目，将其中的web.xml配置文件拷贝到maven项目中，注意修改项目名称。

二、添加xml配置

　　1.web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

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

  </filter>
