使用Eclipse创建一个web项目Maven工程

一、创建项目

刚建好的工程如果报错：The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path

则通过以下配置解决：

 

二、配置

1、首先创建Maven规定的source folder（如果没有自动创建的话）

src/main/resources
src/main/java
src/test/resources
src/test/java

2、配置build path，设置以上四个文件夹的output folder，对应如下图：

3、设置JRE版本

4、将项目转换成Dynamic Web Project

当Dynamic Web Module选择目前一般用的3.0时，报Cannot change version of project facet Dynamic web module to 3.0

① 首先，把Servlet改成3.0，打开项目的web.xml，修改成：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
	id="schedule-console" version="3.0">
</web-app>

② 修改项目的设置，打开项目.settings目录下的org.eclipse.jdt.core.prefs，将1.5改成1.8

eclipse.preferences.version=1
org.eclipse.jdt.core.compiler.codegen.inlineJsrBytecode=enabled
org.eclipse.jdt.core.compiler.codegen.targetPlatform=1.8
org.eclipse.jdt.core.compiler.compliance=1.8
org.eclipse.jdt.core.compiler.problem.assertIdentifier=error
org.eclipse.jdt.core.compiler.problem.enumIdentifier=error
org.eclipse.jdt.core.compiler.problem.forbiddenReference=warning
org.eclipse.jdt.core.compiler.source=1.8

③ 打开org.eclipse.wst.common.project.facet.core.xml，将1.5改成1.8，2.3改成3.0

<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
  <fixed facet="wst.jsdt.web"/>
  <installed facet="java" version="1.8"/>
  <installed facet="jst.web" version="3.0"/>
  <installed facet="wst.jsdt.web" version="1.0"/>
</faceted-project>

④ 重新刷新工程以后，可以看到Dynamic Web Module和Java已经更改了

5、设置部署程序集

测试用的test不需要部署，因此移除test部分

6、配置工程的pom.xml

假设使用的是Spring+SpringMVC+MyBatis，最终编译成war包部署在Tomcat上

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
