我不确定我需要在这里展示哪些文件来帮助解决这个问题，请帮忙:(

currentEntityManager为空。

这是显示错误日志的代码部分：

@Out(scope = ScopeType.SESSION)    
    EntityManager currentEntityManager;

1 个答案:

答案 0 :(得分：2)

错误非常明显，Seam正在尝试退出currentEntityManager值但由于变量为null而无法执行此操作。因此，您需要了解原因null（我认为这是因为emf是null或未打开）。

当currentEntityManager为null时（使用注释的required选项），您可以指示Seam不要投诉。但是，如果您不希望它为null，那么您需要检查原因。

@In(required=false)
@Out(scope=ScopeType.SESSION, required=false)
EntityManager currentEntityManager;

此外，您还不清楚为什么要在该函数中返回cem，以及为什么您没有将currentEntityManager设置为cem的值。
