Question

JSON api错误的堆栈跟踪不显示我的代码的行号。由于可能的原因，搜索我的所有文件都很费时间......

我也读过this - 这很有用，但这只是关于行号的线程。

堆栈跟踪看起来像：

play.api.Application$$anon$1: Execution exception[[JsResultException: JsResultException(errors:List((,List(ValidationError(validate.error.expected.jsarray,WrappedArray())))))]]
at play.api.Application$class.handleError(Application.scala:289) ~[play_2.10.jar:2.1.3]

我没有一个优雅的解决方案，但详细的堆栈跟踪可以在logs\application.log中找到 - 它在这种情况下帮助我
