Question

我做了一个简单的项目来测试EJB3的实现。

使用maven我分别在项目3模块中创建了＆＃34; MyEjb＆＃34; EJB，＆＃34; MyWeb＆＃34; 战争<强大的＆＃34; MyWeb2＆＃34; 另一场战争。 war模块是EJB的客户端。

问题在于，当我部署EAR时，控制台说每个模块创建一个3个EJB上下文。模块MyEjb的EJB上下文不在war模块之间共享，每个模块都从每个MyEjb依赖项中获取数据。

我必须在单独的JAR中创建EJB接口？我使用Jboss作为应用程序服务器。

这里是控制台：

您需要过滤掉应该进入ejb-client模块的内容，而不是。如果您没有指定，那么客户端jar将与普通jar完全相同。实现此目的的一种简单方法是将您的接口放在名为api的包中，并在客户端jar中包含与之匹配的内容。

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-ejb-plugin</artifactId>
    <version>2.3</version>
    <configuration>
         <!--ejbVersion>3.1</ejbVersion-->
         <generateClient>true</generateClient>
         <clientIncludes>
            <clientInclude>**/api/*</clientInclude>
         </clientIncludes>
    </configuration>
</plugin>

如何只将EJB3的接口导入客户端？
