--默认安装的eclipse Preferences菜单下没有server选项

3、安装wtp工具集

--默认安装的eclipse Preferences菜单下没有Project Facets选项

4、修改JSP默认编辑器

--高亮显示jsp文件内容

eclipse创建maven 普通java项目

1、先创建maven父项目（可选）

File -> New -> Project

2、创建maven module子项目

右键parent-project选择Maven选项，创建新的Maven Module Project

创建测试类

eclipse创建maven java web项目

右键parent-project选择Maven选项，创建新的Maven Module Project

勾选后Next

选择war然后Finish

发现没有web.xml

项目（javaweb-project）右键 ->Properties ->Project Facets

点击Apply and Close，web.xml生成了

创建servlet测试java web项目

1、添加项目到server

2、配置pom.xml文件，添加maven依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.dingyibo.test</groupId>
    <artifactId>parent-project</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>
  <groupId>com.dingyibo.test.javaweb</groupId>
  <artifactId>javaweb-project</artifactId>
  <packaging>war</packaging>
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>
  <dependencies>
  	<dependency>
		<groupId>javax.servlet</groupId>
		<artifactId>javax.servlet-api</artifactId>
		<version>3.0.1</version>
		<scope>provided</scope>
  	</dependency>
  </dependencies>
</project>

3、新建index.jsp文件

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>首页</title>
</head>
<body>
   hi,javaweb
</body></html>

4、创建MavenServlet测试类

package com.dingyibo.test.javaweb.servlet;
import java.io.IOException;
public class MavenServlet extends javax.servlet.http.HttpServlet {
	protected void doPost(javax.servlet.http.HttpServletRequest request, 
			javax.servlet.http.HttpServletResponse response) 
					throws javax.servlet.ServletException, IOException {
		response.getWriter().write("hello maven");
	}
	protected void doGet(javax.servlet.http.HttpServletRequest request, 
			javax.servlet.http.HttpServletResponse response) 
					throws javax.servlet.ServletException, IOException {
		doPost(request,response);
	}}

5、配置web.xml添加servlet配置

<?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="WebApp_ID" version="3.0">
  <display-name>javaweb-project</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
  <servlet>
	    <servlet-name>MavenServlet</servlet-name>
		<servlet-class>com.dingyibo.test.javaweb.servlet.MavenServlet</servlet-class>
  </servlet>
  <servlet-mapping>
		<servlet-name>MavenServlet</servlet-name>
		<url-pattern>/maven-java-web</url-pattern>
  </servlet-mapping>
</web-app>
