我有一个需要使用 PlayORM 来完成插入/查询等工作的网络应用程序。我的代码在本地运行没有任何问题，但出现以下警告消息：

com.alvazan.orm.impl.meta.scan.ScannerForClass processIdFieldWorksWARN：我们避免重复扫描一个 class=class com.alvazan.orm.impl.meta.data.MetaClassSingle 一切仍然可以正常工作，但请向我们发送堆栈跟踪，以便我们可以看到为什么会发生这种情况 java.lang.RuntimeException: null at com.alvazan.orm.impl.meta.scan.ScannerForClass.processIdFieldWorks(ScannerForClass.java:234) [playorm-1.4.3.jar:1.4.3 December 13 2012]

但是当我尝试在 JSF 页面上执行该代码时，该代码不起作用。以下是错误信息：

INFO caoimpl.meta.scan.ScannerForClass - 扫描类=类 com.alvazan.orm.api.z8spi.meta.DboColumnMeta java.lang.RuntimeException: 失败扫描类（参见链式异常）=类 com.alvazan.orm.api。 z8spi.meta.DboColumnMeta

有人知道我能做些什么来解决这个问题吗？

好的，确实有两个不同的问题正在发生

  1. 你为什么要进行第二次扫描
  2. NoClassDefFoundError

让我们先解决 NoClassDefFoundError。请不要生气，但我将从基础开始，因为我不知道你的水平，所以你可能已经知道这些东西。

  1. 我们看到 NoClassDefError 或基本上是http://docs.oracle.com/javase/6/docs/api/java/lang/NoClassDefFoundError.html
  2. 我们知道如果缺少 jar 可能会发生这种情况，但是在代码中我们看到它是从另一个应该在同一个 jar 中的类调用的
  3. 另一次我们得到这个错误是我们在某个框架新创建的类加载器中

  4. 在这条线上 com.s1mbi0se.dmp.da.dao.PlayOrmConfiguration.init(PlayOrmConfiguration.java:45) 你应该像这样添加一行

    类 temp = DboColumnMeta.class 类 temp2 = MetaAbstractClass.class temp.getSimpleName(); temp2.​​getSimpleName();

如果您的代码看不到该类，那么这当然是您的代码无法访问它的问题。这是否通过？

让我们跳到问题#1，这不是一个关键问题。在最新版本中，我们添加了 if(log.isDebugEnabled()) savePreviousTrace() 以便我们可以同时获取两个跟踪。如果你有时间，你可以从 git 中检查出来，如果你在 windows 上运行“./gradlew build”或“gradle.bat build”。

让我知道数字 2 的状态，因为如果它在代码下方失败，那么“应该”上面的那些行会失败。

谢谢，院长
