maven3创建多模块web项目

实现步骤

创建项目目录
进入“工作空间”目录，创建名为treasure的文件夹，切换至控制台，进入该文件夹。

配置模块

生成各个模块

maven-archetype-quickstart

默认的Archetype,基本内容包括：

一个包含junit依赖声明的pom.xml
src/main/java主代码目录及一个名为App的类
src/test/java测试代码目录及一个名为AppTest的测试用例

maven-archetype-webapp

一个最简单的Maven war项目模板，当需要快速创建一个Web应用的时候可以使用它。生成的项目内容包括：

一个packaging为war且带有junit依赖声明的pom.xml
src/main/webapp/目录
src/main/webapp/index.jsp文件
src/main/webapp/WEB-INF/web.xml文件

该步骤会依次生成项目的各个模块，但是生成的模块并没有创建依赖，只是最简单的并且符合maven 要求的项目结构的模块，关于什么是 maven 的标准项目结构，可以参考 maven 官方文档，或者《 maven 权威指南》。

# parent 模块创建

创建parent目录，创建pom文件。

配置项目模块
在treasure根目录下新建一个 pom.xml 配置文件，加入如下内容：

<?xml version="1.0" encoding="UTF-8"?>

<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>

    <parent>

        <groupId>com.mirror</groupId>

        <artifactId>mirror-parent</artifactId>

        <version>1.0.0-SNAPSHOT</version>

        <relativePath>./parent/</relativePath>

    </parent>

    <artifactId>mirror-modules</artifactId>

    <name>mirror::modules</name>

    <packaging>pom</packaging>

    <modules>

        <module>parent</module>

        <module>mirror-client</module>

        <module>mirror-utils</module>

        <module>mirror-core</module>

    <module>mirror-web</module>

  </modules>

</project>

修改配置完成之后，在treasure目录下，执行：

mvn clean install
mvn eclipse:eclipse
生成 Eclipse 项目文件及包引用定义，注意，需确保定义Classpath Variables: M2_REPO，指向本地maven类库目录。

打开Eclipse ，导入工程即可。

控制端cd到mirror-web手动运行mvn -Djetty.port=80 jetty:run

或者配置对应的tomcat进行上传部署，mvn tomcat:run
