MAVEN转web项目

新建普通maven项目

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>
