Eclipslink - 未知实体类型

发布于 2024-11-01 18:18:37 字数 11537 浏览 1 评论 0原文

我正在使用 Netbeans 生成的一些实体。一代之后我测试了它们，它们工作得很好。因此，我必须继续下一步，并将它们与我的 JAXB 对象结合起来。与 JAXB 对象结合后，我可以毫无问题地解组我的 XML 流。但是，当我尝试将这些类中的任何一个用于任何与实体相关的内容时，我会收到一些错误。

我现在又回到了测试阶段，这就是我所拥有的。我有一个测试类只是从一个简单的 main 方法运行。我最初用来测试实体的设置相同。下面您将看到测试类、类实体、导致问题 JoinAssetToSku 和错误的实体。我遗漏了实体的大部分 setter 和 getter。有谁知道这个 JoinAssetToSku.findByTs 查询有什么问题。我不明白它是如何导致该错误的，它没有自我意识！？

进行测试的代码：

public void testClassEntity(){
        testClass = new Classes(1);
        testClass.setClassId("12");
        testClass.setDescription("The First Class");
        testClass.setTs(new java.sql.Timestamp(new Date().getTime()));
        ClassesJpaController cc = new ClassesJpaController();
            try {
                cc.create(testClass);
            } catch (PreexistingEntityException ex) {
                Logger.getLogger(EntityTest.class.getName()).log(Level.SEVERE, null, ex);
            } catch (Exception ex) {
                Logger.getLogger(EntityTest.class.getName()).log(Level.SEVERE, null, ex);
            }
    }

原文

I am using some entities generated by Netbeans. After generation I tested them and they were working fine. So then I had to move to my next step and combine those with my JAXB objects. After combining with the JAXB objects I am able to unmarshall my XML stream with no problem. But when I try to use any of those classes for anything entity related I get some errors.

I am back at the testing phase again now and here is what I have. I have a test class just running from a simple main method. The same setup I used to test the entities originally. Below you will see that test class, the Classes entity, The entity causing the issues JoinAssetToSku and the error. I have left out the majority of the setters and getters of the entities. Does anyone know what is wrong with this JoinAssetToSku.findByTs query. I do not understand how it causes that error, it is not self aware!?

The code to do the testing:

public void testClassEntity(){
        testClass = new Classes(1);
        testClass.setClassId("12");
        testClass.setDescription("The First Class");
        testClass.setTs(new java.sql.Timestamp(new Date().getTime()));
        ClassesJpaController cc = new ClassesJpaController();
            try {
                cc.create(testClass);
            } catch (PreexistingEntityException ex) {
                Logger.getLogger(EntityTest.class.getName()).log(Level.SEVERE, null, ex);
            } catch (Exception ex) {
                Logger.getLogger(EntityTest.class.getName()).log(Level.SEVERE, null, ex);
            }
    }

这是我的一个错误，组合生成的实体和生成的 JAXB 类导致我发现一些命名不正确的类。

类名称应为 JoinAssetToSku 以匹配命名查询。或者，我可以将类名称保留为 JoinAssetToSKU 并更改命名查询。

我选择更改班级名称。

This was an error on my part, Combining the generated entities and generated JAXB classes led me to some classes named improperly.

The class name should be JoinAssetToSku to match the named query. Or I could leave the class name as JoinAssetToSKU and change the named query.

I chose to change the class name.
