创建简单的Web应用

mvn archetype:create -DgroupId=me.andy.practice -DartifactId=practice -DpackageName=me.andy.practice -DarchetypeArtifactId=maven-archetype-webapp

生成pom.xml文件

<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 http://maven.apache.org/maven-v4_0_0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>me.andy.practice</groupId>  <artifactId>practice</artifactId>  <packaging>war</packaging>  <version>1.0-SNAPSHOT</version>  <name>practice Maven Webapp</name>  <url>http://maven.apache.org</url>  <dependencies>    <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>3.8.1</version>      <scope>test</scope>    </dependency>  </dependencies>  <build>    <finalName>practice</finalName>  </build></project>

packaging元素的值为war，这个项目会打包成war文件，运行mvn package

集成jetty服务器插件

<build>        <finalName>practice</finalName>        <plugins>            <plugin>                <groupId>org.mortbay.jetty</groupId>                <artifactId>maven-jetty-plugin</artifactId>            </plugin>        </plugins>    </build>

运行mvn jetty:run成功后，访问http://localhost:8080/practice/可以看src/main/webapp/index.jsp内容

<html><body><h2>Hello World!</h2></body></html>

添加J2EE依赖

<dependency>            <groupId>javax.servlet</groupId>            <artifactId>javax.servlet-api</artifactId>            <version>3.0.1</version></dependency><dependency>            <groupId>javax</groupId>            <artifactId>javaee-api</artifactId>            <version>6.0</version></dependency>

构建一个父模块

<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 http://maven.apache.org/maven-v4_0_0.xsd">    <modelVersion>4.0.0</modelVersion>    <groupId>me.andy.practice</groupId>    <artifactId>practice-parent</artifactId>    <packaging>pom</packaging>    <version>1.0-SNAPSHOT</version>    <name>practice Parent Project</name>    <url>http://maven.apache.org</url>    <modules>        <module>practice</module>    </modules>    <build>        <pluginManagement>            <plugins>                <plugin>                    <groupId>org.apache.maven.plugins</groupId>                    <artifactId>maven-compiler-plugin</artifactId>                    <configuration>                        <source>1.7</source>                        <target>1.7</target>                    </configuration>                </plugin>            </plugins>        </pluginManagement>    </build>    <dependencies>        <dependency>            <groupId>junit</groupId>            <artifactId>junit</artifactId>            <version>3.8.1</version>            <scope>test</scope>        </dependency>    </dependencies></project>

pom.xml文件

<modules>        <module>practice</module>    </modules>

表示这个父模块下面的子模块

父模块的配置所有子模块都会继承

pluginManagement定义子模块重用的插件

子模块指向父模块

 <parent>        <artifactId>practice-parent</artifactId>        <groupId>me.andy.practice</groupId>        <relativePath>../pom.xml</relativePath>        <version>1.0-SNAPSHOT</version></parent>
