开放EJB嵌入式容器的命名约定



我正在使用open-ejb嵌入式容器为javaee应用程序编写测试。该应用程序仅包含一个@Statelessbean并测试

import javax.ejb.embeddable.EJBContainer;
import org.junit.Before;
import org.junit.Test;
public class ProductDaoTest {
private EJBContainer container;
@Before
public void initializeContainerAndDatabase(){
container = EJBContainer.createEJBContainer();
System.out.println(container);
}
@Test
public void test(){
}
}

由于某些原因，嵌入式容器启动的成功与否取决于源代码所在的文件夹名称。我尝试了不同的名字，有些有效，有些无效，模式对我来说似乎是随机的。

hibernate javaee-->不工作
hibernate ejb-->不工作
javaee hibernate-->不工作abc xyz-->工作
hibernate abc xyz def ejb-->不起作用
abc xyz def javaee-->工作
abc xyz def hibernate-->工作

如果失败，异常跟踪为：

org.apache.openejb.OpenEjbContainer$NoModulesFoundException: No modules found to deploy.
1)Maybe descriptors are placed in incorrect location.
Descriptors could go under:
<base-dir>/META-INF or <base-dir>/WEB-INF
but not directly under <base-dir>
Check 'Application Discovery via the Classpath' docs page for more info
2)Maybe no modules are present in the classpath.
Is 'openejb.base' system property pointing to the intended location?

为了确保会话bean在类路径中被发现，我添加了

Enumeration<URL> ejbJars = this.getClass().getClassLoader().getResources("org/ares/hibernate/javaee/dao/ProductDao.class");
while (ejbJars.hasMoreElements()) {
URL url = ejbJars.nextElement();
System.out.println("app = " + url);
}

如本链接中所述。该类在工作和非工作情况下都会被发现。

有没有一个我不知道的命名约定，或者我偶然发现了一个bug？

应用程序的源代码在这里。项目的父目录是abc-def，在运行mvn clean test时，项目将运行。如果父目录名称更改为hibernate-javaee并且应用程序停止工作。

关于命名约定问题，没有。我非常确信你在某个地方(系统属性文件或编程)排除/包括路径。排除/包含允许使用通配符，这就是为什么有些文件夹模式有效，而有些则无效。要不排除任何内容而包含所有内容，请使用以下属性创建EJB容器。

Properties p = new Properties();
p.put("openejb.deployments.classpath.exclude", "");
p.put("openejb.deployments.classpath.include", ".*");
container = EJBContainer.createEJBContainer(p);

请参阅http://tomee.apache.org/application-discovery-via-the-classpath.html以获取进一步的说明。

确保您的EJB将被部署的其他选项。

选项1：应用程序发现

如果不想添加额外的配置文件，则必须确保EJB文件夹是类路径的一部分，并且EJB包含ejb-jar.xml。看见http://tomee.apache.org/application-discovery-via-the-classpath.html以获取进一步的说明。

选项2：配置文件

根据日志，您没有配置配置文件。

INFO - Cannot find the configuration file [conf/openejb.xml].  Will attempt to create one for the beans deployed.

在大多数情况下，这是可以的，自定义配置文件是例外。尝试使用文件夹设置来设置配置文件。看见http://openejb.apache.org/configuration.html以获取进一步的说明。

某些模式会自动从OpenEJB扫描中排除。

请注意，openejb.addition.include=myjarprefix可以允许您将其添加回扫描包含中。它将删除冲突的exclude，因此如果您使用它，请使其尽可能长。它可以在conf/system.properties.中设置
