Open-EJB嵌入式容器的命名约定？

时间：2016-06-08 03:48:50

标签： java-ee ejb tomee openejb

我使用open-ejb嵌入式容器为javaee应用程序编写测试。该应用程序只包含一个@Stateless bean和test 

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或失败取决于放置源代码的文件夹名称。我尝试了不同的名字，有些名字也有用，有些名字并没有，而且这个模式对我来说似乎是随机的。

  

hibernate-javaee - ＆gt;没有工作   hibernate-ejb - ＆gt;没有工作   javaee-hibernate - ＆gt;没有工作   abc-xyz - ＆gt;工作
  hibernate-abc-xyz-def - ＆gt;没有工作   abc-xyz-def-ejb - ＆gt;没有工作   abc-xyz-def-javaee - ＆gt;工作
  abc-xyz-def-hibernate - ＆gt;工作

如果失败，则异常跟踪为：

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?

为确保在类路径中发现会话bean，我已添加

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this link中所述。在工作和非工作的情况下都会发现这个课程。

是否存在一个我不知道或者我偶然发现错误的命名约定？

该应用程序的源代码是here。项目的父目录是abc-def，在运行mvn clean test时，项目会运行。如果父目录名称更改为hibernate-javaee并且应用程序停止工作。

3 个答案:

答案 0 :(得分：1)

关于命名约定问题，没有。我很确定你在某处（系统属性文件或以编程方式）排除/包括路径。排除/包括允许使用通配符，这是因为某些文件夹模式有效，有些没有。要排除任何内容并包括所有创建具有以下属性的EJB容器。

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

有关详细说明，请参阅http://tomee.apache.org/application-discovery-via-the-classpath.html。

确保部署EJB的其他选项。

选项1：应用程序发现

如果您不想添加其他配置文件，则必须确保EJB文件夹是类路径的一部分，并且您的EJB包含ejb-jar.xml。有关详细说明，请参阅http://tomee.apache.org/application-discovery-via-the-classpath.html。

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，这很好，自定义配置文件也是例外。尝试使用文件夹设置设置配置文件。有关详细说明，请参阅http://openejb.apache.org/configuration.html。

答案 1 :(得分：0)

某些patterns会自动从OpenEJB扫描中排除。

答案 2 :(得分：0)

请注意，openejb.additional.include = myjarprefix可以允许您将其添加回扫描包含中。它将删除冲突的排除项，因此如果您使用它，请尽可能延长它。它可以在conf / system.properties中设置。
