#### 问题描述:maven项目出现如下错误

解决方案:
首先,将webapp下的web.xml文件
1 <?xml version="1.0" encoding="UTF-8"?>
2 <!-- <!DOCTYPE web-app
3 PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
4 "http://java.sun.com/dtd/web-app_2_3.dtd">
替换为
按 Ctrl+C 复制代码
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">
<display-name>Archetype Created Web Application</display-name>
</web-app>
按 Ctrl+C 复制代码
然后,关闭Eclipse,改项目下的.settings\org.eclipse.wst.common.project.facet.core.xml,将 版本改成为3.0,将成后是<installed facet="jst.web" version="3.0"/>,再启动Eclipse.
最后,在Problems View的出错提示右键选Quick Fix,再按提示确定就OK;或者,右键项目->Maven->Update Project
=====================
此时,问题一般解决。如还不能解决,尝试在pom.xml中加入如下代码:
复制代码
