java EJB注入错误
我有一个EAR文件(JEE6),其中包含一个EJBJAR(示例ejb)文件和一个war文件(示例web)。 结构如下:
sample-ear
|----sample-ejb.jar
| |---TestEjb.java (@Singleton)
|
|----sample-web
|---StartupEjb.java (@Singleton,@Startup)
|---TestListener.java (@WebListener)
当我想将TestEjb注入StartupEjb或TestListener时:
@EJB
private TestEjb testEjb;
我发现以下错误:
玻璃鱼:
Caused by: com.sun.enterprise.container.common.spi.util.InjectionException: Exception attempting to inject Remote ejb-ref name=com.sample.StartupEjb/testEjb,Remote 3.x interface =com.sample.TestEjb,ejb-link=null,lookup=,mappedName=,jndi-name=com.sample.TestEjb,refType=Session into class com.sample.StartupEjb: Lookup failed for 'java:comp/env/com.sample.StartupEjb/testEjb' in SerialContext[myEnv={java.naming.factory.initial=com.sun.enterprise.naming.impl.SerialInitContextFactory, java.naming.factory.state=com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl, java.naming.factory.url.pkgs=com.sun.enterprise.naming}
weblogic:
Caused By: weblogic.application.naming.ReferenceResolutionException: [J2EE:160200]Error resolving ejb-ref "com.sample.StartupEjb/testEjb" from module "sample-web-1.0-SNAPSHOT.war" of application "com.sample_sample-ear_ear_1.0-SNAPSHOT". The ejb-ref does not have an ejb-link and the JNDI name of the target bean has not been specified. Attempts to automatically link the ejb-ref to its target bean failed because no EJBs in the application were found to implement the "com.sample.TestEjb" interface. Link or map this ejb-ref to its target EJB and ensure the interfaces declared in the ejb-ref are correct.
Glassfish和Weblogic都找不到TestEjb
顺便说一句,当我为TestEjb创建一个远程接口并将其用于注入时,它工作得很好! 但我不想定义远程接口,我想使用没有接口的EJB。我不认为我必须为这个简单的用例定义一个远程接口

这是一个使用NetBeans创建的简单Maven项目
# 1 楼答案
通常必须定义一个本地接口,例如
如果明确避免使用此接口,则必须将bean标记为@LocalBean:
注:代码未经测试,但应该会有所帮助
