Question

我是Maven的新手并且也在学习它。我在eclipse中有两个项目，一个是包含UI东西的零售产品，另一个项目是ejb项目零售服务。我为这两个项目编写了单独的pom文件，并能够生成war和jar文件。我要做的是。

a）我必须在war文件中配置jar文件，因为jar文件包含webappliction所需的ejb内容 b）创建war文件后，我必须创建ear文件，该文件将包含war文件。

我该怎么办呢。

我在这里提供了两个pom.xmls。

Answer 1

在构建包含WAR和EJB模块的Java EE 5.0应用程序时，通常有3个Maven模块定义：

网络应用
的EJB
EAR

您有前两个但没有EAR模块。看起来应该是这样的：

<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>Retail</groupId>
    <artifactId>RetailEAR</artifactId>
    <packaging>ear</packaging>
    <version>0.0.1-SNAPSHOT</version>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-ear-plugin</artifactId>
                <version>2.8</version>
                <configuration>
                    <defaultLibBundleDir>lib</defaultLibBundleDir>
                    <skinnyWars>true</skinnyWars>
                    <version>5</version>
                </configuration>
            </plugin>
        </plugins>
    </build>

    <dependencies>
        <dependency>
            <groupId>RetailService</groupId>
            <artifactId>RetailService</artifactId>
            <type>ejb</type>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>RetailProducts</groupId>
            <artifactId>RetailProducts</artifactId>
            <type>war</type>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>
    </dependencies>

</project>

然后，当您打包EAR模块时，它会处理Web应用程序的依赖项。参数skinnyWars控制是否应在WAR内部复制依赖项。通常你不希望它们在WAR中，因为它们可以从EAR本身访问Web应用程序。
