Eclipse下Maven插件配置

要做一个基于C/S架构的汽车租赁系统，由于在实习期间接触过一些Java和SpringMVC，Spring，Hibernate的东西，所以决定使用这个框架组合来完成这个项目。

首先是Maven的配置，为啥要用Maven呢？"Maven 除了以程序构建能力为特色之外，还提供高级项目管理工具。由于 Maven 的缺省构建规则有较高的可重用性，所以常常用两三行 Maven 构建脚本就可以构建简单的项目。由于 Maven 的面向项目的方法，许多 Apache Jakarta 项目发文时使用 Maven，而且公司项目采用 Maven 的比例在持续增长。"所以了解一下Maven是极好的。

我用的Maven是Eclipse插件。Eclipse是J2EE，Version: Luna Service Release 2 (4.4.2)），插件地址：http://m2eclipse.sonatype.org/sites/m2e

一、创建一个Dynamic Web Project

File->new->Dynamic Web Project,然后填上项目名称，绑定Apache Tomcat 服务器。如果不是新建的Dynamic Web Project的话，就要修改工程的Project Facets，选中项目右键点击Properties,在Project Facets中选择Dynamic Web Module 和 Jave（只有经过上述两步操作才能在Tomcat中发布），如果修改此处后还是无法在Apace的tomcat service中Add此项目，就可以查看org.eclipse.wst.common.project.facet.core.xml的文件，里面配 置有各种版本信息。

二、配置输出（Deployment Assembly）

右键项目文件，选择Properties，然后可以看到弹出的模态对话框中的Deployment Assembly项，点击，修改相应的Source和Deploy Path，它们表示发布项目的源文件，和编译之后的class的目录。这里要加上Maven包，只有这样Maven管理的包才能发布过去。或者可以直接修改修改.settings（在Navigation视图中）文件夹下的org.eclipse.wst.common.component文件中的配置，此配置是配置发布后对应的路径。

<?xml version="1.0" encoding="UTF-8"?><project-modules id="moduleCoreId" project-version="1.5.0">

<wb-module deploy-name="carrental">

<wb-resource deploy-path="/" source-path="/target/m2e-wtp/web-resources"/>

<wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/config"/>

<wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/java"/>

<wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/webapp" tag="defaultRootSource"/>

<wb-resource deploy-path="/WEB-INF/classes" source-path="/src/test"/>

<property name="java-output-path" value="/carrental/build/classes"/>

<property name="context-root" value="accounts"/>

</wb-module>

</project-modules>

三、配置Java Build Path

同样还是在项目的Properties面板下，可以看到Deployment Assembly项下有Java Build Path一项，点进去，可以看到Libraries一项下面增加了Maven dependencies。如果没有的话就说明Deployment Assembly没有配置好，重复检查一下。我们要做的呢就是在Java Build Path 的Order and Export中配置 Build Path，勾上Maven的管理包，如果Java jdk没有勾上，也要勾上。另外也可以修改.classpath文件，在其中加入包的依赖，这样在发布时可以将由Maven管理的包直接发布过去。如：

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

<classpath>

<classpathentry kind="src" path="src/test"/>

<classpathentry kind="src" path="src/main/config"/>

<classpathentry kind="src" output="target/classes" path="src/main/java">

<attributes>

<attribute name="optional" value="true"/>

<attribute name="maven.pomderived" value="true"/>

</attributes>

</classpathentry>

<classpathentry exported="true" kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">

<attributes>

<attribute name="maven.pomderived" value="true"/>

<attribute name="org.eclipse.jst.component.dependency" value="/WEB-INF/lib"/>

</attributes>

</classpathentry>

<classpathentry exported="true" kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/jdk1.8.0_40"/>

<classpathentry kind="output" path="target/classes"/>

</classpath>

以上的文件如果找不到的话，选中Window->show view->Navigator，切换到Navigator视图下就可以了。

四、为Maven添加依赖的包

经过以上的步骤呢，基本的Maven管理包环境已经搭建好了，可以打开Pom.xml文件添加需要的包了，关于更多Pom.xml的信息可以参考这个blog：http://blog.csdn.net/zhuxinhua/article/details/5788546，它的几个重要视图作用分别是：

Overview:显示maven项目的一些基本信息.
Dependencies:添加jar包的页面
Plugins:添加maven插件的页面.比如tomcat-maven-plugin等.
Dependency Hierarchy:用于显示jar包的依赖关系.没事的时候可以看看jar包的依赖关系.
Effective POM:显示maven的编译路径,plugin之类的.也可以无视.
pom.xml:导入jar包的信息,可以在其中进行修改.重要

添加依赖的包就是在Dependencies视图下，把需要添加的包和其版本输入进去就可以了。当然也可以直接编辑pom.xml文件。

我这里添加了SpringMVC，Spring，Hibernate，Mysql connector等的包，相应的项目添加就行了。我的pom.xml文件如下：
