使用Maven创建支持Eclipse导入的Web项目

maven创建web项目的命令

mvn archetype:generate -DgroupId={packaging.path} -DartifactId={project-id}
-DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false

P.S 替换 “{packaging.path}” 和“{project-id}” 的值为你想要的值

以下是一个具体的实例

1. mvn archetype:generate

首先在命令行下切换到你想要创建项目的目录，执行以下命令：

N:\>cd workshop

N:\workshop> mvn archetype:generate -DgroupId=net.cublog.jersey -DartifactId=helloworldjersey  -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false

你会看到如下输出：

N:\workshop> mvn archetype:generate -DgroupId=net.cublog.jersey -DartifactId=hel
loworldjersey  -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=fa

2. Maven生成的Web项目的结构

Maven 会生成“Maven Standard Web Application Directory Layout“. See following diagram :

A new super clean “web.xml” file is created under “N:\workshop\helloworldjersey\src\main\webapp\WEB-INF” folder.

File : web.xml

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>
</web-app>

 3. pom.xml

Refer to the generated pom.xml file, the tag “packaging” is “war“, when build with Maven, this project will group it into a war file for deployment.

File : pom.xml

<project xmlns=""
  xmlns:xsi=""
  xsi:schemaLocation="
  ">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.mkyong.core</groupId>
  <artifactId>mkyongweb-core</artifactId>
  <packaging>war</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>mkyongweb-core 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>mkyongweb-core</finalName>
  </build>
</project>

Done. Maven generated a standard web application project structure and a simple web.xml file.

4. mvn eclipse:eclipse -Dwtpversion=2.0

将maven生成的java项目转化为支持eclipse的java项目只需要执行以下命令 :

mvn eclipse:eclipse

对于web项目，你需要额外的参数才能够让它支持Eclipse’s wtp, 所以为了将maven生成的web项目转化为支持eclipse的项目，需要执行以下命令 :

mvn eclipse:eclipse -Dwtpversion=2.0

5. Eclipse WTP

Standard Eclipse’s “.classpath” and “.project” files are created. And you will noticed a new “.setting” folder is created and inside contains “org.eclipse.wst.common.component” and “org.eclipse.wst.common.project.facet.core.xml“, both files for WTP or Faces support in Eclipse.


6. Import into Eclipse IDE

Now, you have everything what a Eclipse web application want, so, you can start import your Maven based web application into Eclipse IDE.

Steps :
In Eclipse IDE, menu bar , File -> Import… -> General -> Existing Projects into Workspace -> select root directory (select your project folder) -> Done.

------------------------------------------------------------------------------
导入后需要右击项目--maven--enable maven dependence
有可能由于eclipse，wtp的版本不一样，在项目名前面显示一个红叉。
可以通过eclipse创建一个动态网站项目，然后将.setting文件夹中的文件进行替换。
