我不确定需要在此处显示哪些文件来帮助解决此问题，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;

最佳答案

错误非常明显，Seam 正在尝试输出 currentEntityManager 值，但无法执行此操作，因为变量为 null。因此，您需要了解为什么它是 null (我推测是因为 emf 是 null 或未打开)。

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

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

此外，尚不清楚为什么在该函数中返回 cem，以及为什么不使用 cem 的值设置 currentEntityManager .
