如果我在EJB中使用SpringBeanAutowiringInterceptor獲取EJB異常

我在使用SpringBeanAutowiringInterceptor（我正在使用JDK 1.7.0_51和Weblogic12）時收到調用EJB的異常。如果我在EJB中使用SpringBeanAutowiringInterceptor獲取EJB異常

像往常一樣，當我得到這樣的異常，我嘗試創建一個示例應用程序，看看我的應用程序中的任何現有代碼可能有衝突庫。只是爲了從我的主要應用程序隔離它。

所以我來到這裏：

我有一個EJB定義爲（不是我評論@Interceptors(SpringBeanAutowiringInterceptor.class)

package my.company.impl; 

import my.company.client.remote.CalculatorRemote; 
import org.springframework.stereotype.Component; 

import javax.ejb.Remote; 
import javax.ejb.Stateless; 


@Stateless(mappedName = "ejb/MyCalcuatorEJB") 
@Remote(CalculatorRemote.class) 
//@Interceptors(SpringBeanAutowiringInterceptor.class) 
@Component 
public class CalculatorEJB implements CalculatorRemote { 

    private static final long serialVersionUID = 1L; 

    @Override 
    public int add(final int a, final int b) { 
     return a+b; 
    } 
}

而且一個Maven POM

我EAR部署到WebLogic和從IntelliJ我有一個測試類如下

import my.company.client.remote.CalculatorRemote; 

import javax.naming.Context; 
import javax.naming.NamingException; 
import java.util.Hashtable; 

public class TestClient { 

    public static void main(String[] args) { 
     try { 
      testUsingJavaSe(); 
     } catch (final Exception ex) { 
      ex.printStackTrace(); 
     } 
    } 

    private static void testUsingJavaSe() throws NamingException { 
     Hashtable<String, String> env = new Hashtable<String, String>(); 
     env.put("java.naming.provider.url", "t3://127.0.0.1:7002"); 
     System.out.println("creating context"); 
     Context ic = new weblogic.jndi.WLInitialContextFactory().getInitialContext(env); 
     System.out.println("looking up object"); 
     Object object = ic.lookup("ejb/MyCalcuatorEJB#my.company.client.remote.CalculatorRemote"); 

     CalculatorRemote remote = (CalculatorRemote) object; 
     System.out.println(remote); 

     System.out.println("invoking ejb"); 
     int result = remote.add(1, 2); 

     System.out.println("result: " + result); 
    } 

}

現在所有這些工作，當我運行測試類時，我可以看到3被打印到控制檯窗口。

在我的應用程序中，我需要額外的bean在我的EJB中。由於我使用彈簧，我想使用@Autowired。根據我的理解，我需要刪除@Component註釋並將其替換爲@Interceptors(SpringBeanAutowiringInterceptor.class)。

但是爲了使用它，我取消以下依賴性在我的POM

<dependency> 
      <groupId>javax.interceptor</groupId> 
      <artifactId>javax.interceptor-api</artifactId> 
      <scope>provided</scope> 
      <version>1.2</version> 
     </dependency>

這讓我導入@Interceptors(SpringBeanAutowiringInterceptor.class)。

這將允許我啓動可以掃描類和注入bean的Spring Context。

我也有一個beanRefContext.xml，用來啓動我的spring上下文。

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
          http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> 

    <bean id="calculatorService" class="org.springframework.context.support.ClassPathXmlApplicationContext"> 
     <constructor-arg value="classpath*:applicationContext.xml"/> 
    </bean> 
</beans>

指向空applicaitonContext.xml文件

     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

我沒有任何自動裝配還...只是想測試線路和相關工作。

但如果我現在再運行它，我得到以下錯誤

我不知道我在做什麼錯在這裏。任何想法？

'java.lang.ClassNotFoundException：無法加載類 > com.oracle.pitchfork.interfaces.LifecycleCallbackException'這表示jar文件丟失！我想 – VinayVeluri

不知道什麼是正確的解釋是，但我終於得到它通過改變兩兩件事的工作：

  1. 我需要，而不是添加@Interceptors(SpringBeanAutowiringInterceptor.class)到我的班swopping它與@Component又名我既需要。所以，我的EJB類結束看起來像：

    package my.company.impl; 

import my.company.client.remote.CalculatorRemote; 
import org.springframework.stereotype.Component; 

import javax.ejb.Remote; 
import javax.ejb.Stateless; 


@Stateless(mappedName = "ejb/MyCalcuatorEJB") 
@Remote(CalculatorRemote.class) 
@Interceptors(SpringBeanAutowiringInterceptor.class) 
@Component 
public class CalculatorEJB implements CalculatorRemote { 

private static final long serialVersionUID = 1L; 

@Override 
public int add(final int a, final int b) { 
    return a+b; 
}

    }

  2. 我beanRefContext.xml在包src/main/resources/my/company，我搬到了src/main/resources又名現在是在資源文件夾的根。猜測SpringBeanAutowiringInterceptor只會掃描根。

如果任何人可以闡明爲什麼這是請它可能會幫助另一個人。
