使用Maven构建企业应用程序

标签： java maven

我正在学习Maven，我需要一些帮助来了解它是如何工作的。

我有一个申请。之前的建筑是使用ANT制作的。现在我正在将它迁移到Maven。我想制作.ear文件。应用程序是WSDL优先的Web服务，因为我使用的是cxf-codegen-plugin Maven插件。代码生成成功，除了如何生成生成源的.jar文件之外，该部分的一切正常。

是否可以使用一个Maven pom.xml文件构建应用程序？或者我需要单独的Maven文件来构建生成源的.jar文件，构建.war文件和其他pom.xml文件以最终构建.ear文件？

我的maven文件如下所示：

当我运行此脚本.ear文件被创建，但没有.war文件。创建工件的顺序应该是：generate-code-from-wsdl，compile-it，make-jar，build-war，build-ear。

如何使用Maven构建该目标序列？

经过一些尝试和测试后，我成功地完成了自己的工作。

我创建了一个名为BizzBu​​zzWSEAR的项目，然后我为它创建了pom.xml文件。它看起来像这样：

<?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/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.groupgti.ws.bizzbuzz</groupId>
    <artifactId>BizzBuzzWSEAR</artifactId>
    <version>1.0</version>
    <modules>
        <module>BizzBuzz-web</module>
        <module>BizzBuzz-ear</module>
        <module>BizzBuzz-cxf</module>
    </modules>
    <packaging>pom</packaging>
    <name>BizzBuzzWSEAR</name>
</project>

然后我创建了另外三个模块：

BizzBu​​zz-web - 用于Web应用程序（Web服务） BizzBu​​zz-ear - 用于企业应用程序 BizzBu​​zz-cxf - 用于wsdl2java .jar文件

BizzBu​​zz-web模块pom.xml如下所示：

然后，当我构建我的项目时，BizzBu​​zzWSEAR pom.xml文件构建所有内容并打包到.ear文件。希望这些信息对某人有用。

答案 1 :(得分：1)

以下是有关您创建的pom的一些提示/建议/改进：

首先，您应该定义版本1.0-SNAPSHOT而不是1.0，因为您的应用正在开发中，尚未发布。

在这种情况下，您有一个多模块构建，在使用时有一些优势。您正在每个模块中定义版本号和组ID，如下所示：

<parent>
    <artifactId>BizzBuzzWSEAR</artifactId>
    <groupId>com.groupgti.ws.bizzbuzz</groupId>
    <version>1.0</version>
</parent>
<artifactId>BizzBuzz-web</artifactId>
<groupId>com.groupgti.ws.bizzbuzz</groupId>
<version>1.0</version>
<packaging>war</packaging>

在您的多模块构建中，您可以将其减少到以下（最佳实践）：

<parent>
    <artifactId>BizzBuzzWSEAR</artifactId>
    <groupId>com.groupgti.ws.bizzbuzz</groupId>
    <version>1.0</version>
</parent>

<artifactId>BizzBuzz-web</artifactId>
<packaging>war</packaging>

groupId和版本将由父级继承到模块，这使得pom变小。

此外，您应该使用属性等全局配置：

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

进入父母pom。除此之外，您还可以为父项中的插件定义默认版本等，以及以下（父）：

  <build>
    <pluginManagement>
      <plugins>
       <plugin>
           <groupId>org.apache.maven.plugins</groupId>
           <artifactId>maven-compiler-plugin</artifactId>
           <version>2.3.2</version>
           <configuration>
              <source>1.6</source>
              <target>1.6</target>
           </configuration>
       </plugin>

       <plugin>
           <groupId>org.apache.maven.plugins</groupId>
           <artifactId>maven-ear-plugin</artifactId>
           <version>2.6</version>
           <configuration>
              <version>6</version>
              <defaultLibBundleDir>lib</defaultLibBundleDir>
           </configuration>
       </plugin>
     ...

将导致以下耳模块pom：

<?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"
