Question

Simple WebSevice

@WebService
@Stateless
public class HistoryFormatterWebService implements IHistoryFormatterWebService
{
   @EJB
   private IHistoryFormatter historyFormatter;

   public byte[] formatHistory(final byte[] data)
   {
      System.err.println("hello from service");

      return null;
   }
}

IHistoryFormatter

@Local
public interface IHistoryFormatter
{  
// ..  
}

IHistoryFormatter是来自另一个项目的bean（query-ear.ear），但他也部署在jBoss上。
我的WebService正常部署在jBoss上。而jBoss写道

11:17:09,506 INFO  [JmxKernelAbstraction] installing MBean: jboss.j2ee:ear=wsformatter-ear-1.0-SNAPSHOT.ear,jar=wsformatter-ejb-1.0-SNAPSHOT.jar,name=HistoryFormatterWebService,service=EJB3 with dependencies:
11:17:09,568 INFO  [JmxKernelAbstraction]   jboss.j2ee:ear=query-ear.ear,jar=query-services.jar,name=HistoryFormatter,service=EJB3
11:17:09,568 INFO  [EJBContainer] STARTED EJB: com.wsformatter.HistoryFormatterWebService ejbName: HistoryFormatterWebService

但是当我向它发送请求时（使用SoapUI）我得到了异常

java.lang.RuntimeException: Non matching type for inject of field: private com.softcomputer.softlab.lquery.service.IHistoryFormatter com.softcomputer.wsformatter.HistoryFormatterWebService.historyFormatter for type: $Proxy250 of jndiName env/com.softcomputer.wsformatter.HistoryFormatterWebService/historyFormatter

有人可以帮助我吗？

Answer 1

只是猜测：

java.lang.RuntimeException: Non matching type for inject of field: 
[...] com.softcomputer.softlab.lquery.service.IHistoryFormatter [...] for type: 
[...] of [...] com.softcomputer.softlab.lquery.service.IHistoryFormatter[...]

对我来说，有两个类加载器加载了两个类IHistoryFormatter。即使这些类具有相同的名称，如果它们已被不同的类加载器加载，它们也会被视为不同。

因此，请检查接口类的包装 - 理想情况下，它们应该只在JBoss的一个位置提供。

使用EJB注释的依赖注入
