如何编写可以看到我的EJB服务的JUnit测试？ [英] how to write a JUnit test that can see my EJB service?

问题描述

我有一个在WebSphere 7上运行的Java EE应用程序（使用IBM RAD 7.5 / Eclipse）。

它基本上是user.JSP - > UserServlet - > @Stateless UserService - > UserDAO - > Oracle

我想为UserService编写一些JUnit测试。

我启动来自Eclipse的应用程序正在WebSphere上运行。我在Eclipse中的一个新的Java项目中进行了一个JUnit测试。我的问题是，我的JUnit测试如何访问UserService的引用？

有没有办法让我像@EJB注释一样做：

  public class UserTests扩展TestCase {
 
 @EJB 
 private UserServiceLocal userService; 
 
 public void test1（）throws Exception {
 Assert.assertTrue（userService is not null，（userService！= null））; 
} 
 
} 
  

这是我的UserService的基本版本：

  @Stateless 
 public class UserService implements UserServiceLocal {
 
 @EJB 
私人UserDAOLocal userDAO; 
 
 / * ... * / 
} 
  

注意：@EJB不注入任何东西。

注意： userService =（UserServiceLocal）new InitiatContext（）。lookup（UserServiceLocal.JNDI） / code>也不行，说：NamingManager.getURLContext找不到此方案的工厂：ejblocal

  @Local 
 public class interface UserServiceLocal {
 
 public static final String JNDI =ejblocal：com.myapp.service.UserServiceLocal; 
 
 / * ... * / 
} 
  

任何建议非常感谢！

解决方案

那天，我的解决方案是我向EJB添加了一个远程EJB接口，我想从JUnit测试。

我创建了一个新的应用程序客户端项目，并将我的JUnit在那里测试我的JUnit测试执行EJB的远程查找。似乎可以正常工作。

但是，使用WebSphere 7时，我不得不使用createEJBStubs命令生成所需的存根。更多细节在这里和这里：

I have a Java EE application running on WebSphere 7 (using IBM RAD 7.5 / Eclipse).

It's basically user.JSP -> UserServlet -> @Stateless UserService -> UserDAO -> Oracle

I want to write some JUnit tests for the UserService.

I launch the application from within Eclipse, it's running on WebSphere. I have a JUnit test in a new Java project in Eclipse. My question is, how can my JUnit test access a reference to UserService?

Is there a way for me to do something like with an @EJB annotation:

public class UserTests extends TestCase {

  @EJB  
  private UserServiceLocal userService;

  public void test1() throws Exception {
    Assert.assertTrue("userService is not null", (userService != null));
  }

}

Here's a basic version of my UserService:

@Stateless
public class UserService implements UserServiceLocal {

  @EJB
  private UserDAOLocal userDAO;

  /* ... */
}

NOTE: @EJB doesn't inject anything.

NOTE: userService = (UserServiceLocal)new InitiatContext().lookup(UserServiceLocal.JNDI); doesn't work either, says, "NamingManager.getURLContext cannot find the factory for this scheme: ejblocal"

@Local
public class interface UserServiceLocal {

  public static final String JNDI = "ejblocal:com.myapp.service.UserServiceLocal";

  /* ... */
}

Any suggestions are greatly appreciated!

解决方案

At the end of the day, my solution was I added a remote EJB interface to the EJBs I want to test from JUnit.

I created a new "Application Client Project" and put my JUnit tests in there. My JUnit tests do a remote lookup of the EJB. Seems to work okay.

However, using WebSphere 7, I had to use the createEJBStubs command to generate the required stubs. More details here and here:
