为什么在ORM类中具有某个类的ejb参数会导致找不到类错误？

• 问答

我的Java项目在Wildfly上运行时，情况非常奇怪。

我有一个interface，例如

package com.bc.ejb;

//Some imports

@Local
public interface InventoryItemSessionLocal {
    //Some method declarations
}

及其实现

package com.bc.ejb;

//Some imports

@Stateless
public class InventoryItemSession implements InventoryItemSessionLocal {
    //Some method definitions
}

我还有一个ORM类，其定义如下：

打包com.bc.orm; 

//Some imports

@SuppressWarnings("serial")
@Entity
@Table(name="custom_inventory")
@Inheritance(strategy=InheritanceType.JOINED)
public class CustomInventory extends BaseEntity implements Auditable,Serializable {
    //Some method definitions
}

它有这样一种方法：

public boolean updateImageFromBC(InventoryItemSessionLocal iSession,InventoryItem ii) {
    //Some operations
    iSession.update(ii);
}

其中InventoryItem是另一个ORM类。我所有的测试都进展顺利，无可挑剔，但是，有一个名为BreakClient的子项目只能与VPN访问一起使用，而我对此没有VPN访问，因此只能由非技术人员进行测试。 BreakClient具有BreakClientDao class，例如：

package com.bc.dao;

//Some imports

public class BreakClientDao extends BaseDao {
    //Some methods
}

BaseDao定义为

package com.bc.dao

//Some imports

public class BaseDao <T> {
    //Some method definitions
}

如果使用BreakClientSessionFactory class，看起来像

package com.bc.dao;

//Some imports

public class BreakClientSessionFactory {
    //Some method definitions
}

所有这些，我被告知BreakClient停止工作，最初我没有关于实际问题的任何信息，因此，与一个非技术人员一起，我们共同努力找到了对问题负责。我有能力和知识来处理源代码，并且checkout提交并在测试服务器上进行构建和部署，并且她具有对BreakClient的VPN访问权限。经过数小时的可能分支测试，我们找到了负责的分支。现在，负责的分支自己拥有许多提交，因此我们逐个提交地搜索，直到发现有问题的提交为止。我仍然没有足够的信息，向她询问了日志，直到我们意识到在她的计算机上BreakClient记录了错误。这是错误：

看到这一点，我已将updateImageFromBC更改为如下形式：

public boolean updateImageFromBC(Object iSession,InventoryItem ii) {
    //Some Operations
    ((InventoryItemSessionLocal)iSession).update(ii);
}

进行此更改后，我的同事告诉我BreakClient有效。即使这已经解决了问题，我仍然认为我上面的修复很丑陋，并且想改进这段代码，所以我的问题是：

如何在不破坏BreakClient的情况下更改updateImageFromBC以使其看起来像初始实现？

请注意，由于我无法访问BreakClient才能正常工作所需的VPN，因此很难进行测试。
