本文介绍如何使用Maven创建Web项目，包括配置web.xml、添加依赖及Jetty插件等步骤，实现快速部署。

新建普通maven项目

这里写图片描述

建立webapp/WEB-INF与web.xml

在src/main下建立webapp/WEB-INF
src/main/webapp/WEB-INF下建立web.xml
web.xml

<?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>hello app server</display-name>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

添加依赖

更改为war
<packaging>war</packaging>

<dependency>
            <groupId>com.sun</groupId>
            <artifactId>tools</artifactId>
            <version>1.7</version>
            <scope>system</scope>
            <systemPath>${JAVA_HOME}/lib/tools.jar</systemPath>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.8.2</version>
            <scope>test</scope>
        </dependency>
        <!-- servlet -->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <version>3.1.0</version>
            <scope>provided</scope>
        </dependency>
        <!--jsp -->
        <dependency>
            <groupId>javax.servlet.jsp</groupId>
            <artifactId>jsp-api</artifactId>
            <version>2.2</version>
            <scope>provided</scope>
        </dependency>
        <!-- jstl -->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
            <version>1.2</version>
            <scope>runtime</scope>
        </dependency>

选中项目右键maven-update project configuration这样就变成web项目

（可选）添加jetty插件(tomcat跳过)

<build>
        <finalName>hello</finalName>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.3</version>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
            <!--jetty  -->
            <plugin>
                <groupId>org.mortbay.jetty</groupId>
                <artifactId>jetty-maven-plugin</artifactId>
                <!-- <version>8.1.14.v20131031</version> -->
                <version>8.1.16.v20140903</version>

                <configuration>
                    <scanIntervalSeconds>600</scanIntervalSeconds>
                    <scanTargetPatterns>
                        <scanTargetPattern>
                            <directory>src/main/webapp</directory>
                            <includes>
                                <include>**/*.xml</include>
                                <include>**/*.properties</include>
                                <include>**/*.tld</include>
                            </includes>
                        </scanTargetPattern>
                    </scanTargetPatterns>
                    <webAppConfig>
                        <contextPath>/hello</contextPath>
                    </webAppConfig>
                    <connectors>
                        <connector implementation="org.eclipse.jetty.server.nio.SelectChannelConnector">
                            <port>9090</port>
                            <maxIdleTime>60000</maxIdleTime>
                        </connector>
                    </connectors>
                </configuration>
            </plugin>

        </plugins>
    </build>

完成的pom
