java - Weblogic12c部署EJB不明确错误

Question

我正在尝试在 Weblogic 12c 中部署该应用程序。在部署过程中，我收到以下错误

weblogic.management.DeploymentException: weblogic.application.naming.ReferenceResolutionException: [J2EE:160092]Error: The ejb-link "BeanClass" declared in the ejb-ref or ejb-local-ref "...BeanClassService/beanClass" in the module "....EJB.jar" is ambiguous. Qualify this ejb-link to remove the ambiguity.

代码:

IBeanClass.java

@Local

public interface IBeanClass {}

BeanClass.java

@Stateless(name = "BeanClass")

@PermitAll

public class BeanClass implements IBeanClass { ...... }

IBeanClassService.java

@Local

public interface IBeanClassService { ......... }

BeanClassService.java

@Stateless(name = "BeanClassService")

public class BeanClassService implements IBeanClassService {

@EJB(beanName = "BeanClass")

private IBeanClassService beanclass;

... }

我正在从 Web 应用程序项目调用 EJB:

ClientClass.java

public class ClientClass{ ....

@EJB(beanName = "BeanClassService")

private IBeanClassService beanclass;

..... }

代码在 weblogic10 中工作正常，但现在在 weblogic 12 中出现异常。请帮助解决此问题。

Answer 1

BeanClass 不是 IBeanClassService，因此即使按照基本的 java 约定，您也无法将 IBeanClass 对象分配给该变量，更不用说将 EJB 注入(inject)到该位置了。你应该拥有的是

  @EJB(beanName = "BeanClass")

  private IBeanClass beanclass;
