Weblogic12c部署EJB模糊错误

Question

我试图在Weblogic 12c中部署应用程序。在部署过程中，我得到以下错误

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应用程序项目中调用EJB：

ClientClass.java

public class ClientClass{ ....

@EJB(beanName = "BeanClassService")

private IBeanClassService beanclass;

..... }

代码在weblogic10中运行良好，但现在在weblogic 12中出现异常。请帮助解决这个问题。

Answer 1

BeanClass不是IBeanClassService，因此即使按照基本的java约定，也不能将IBeanClass对象分配给该变量，更不用说将EJB注入到该位置了。你应该做的是

  @EJB(beanName = "BeanClass")

  private IBeanClass beanclass;

Answer 2

我也有同样的问题--解决办法是：

<dependency>
    <groupId>bo.sigep.modulo</groupId>
    <artifactId>moduloSigep-ejb</artifactId>
    <version>1.0-SNAPSHOT</version>
<scope>provided</scope>
</dependency>
