將log4j消息記錄到數據庫中

Question

嗨，我正在開發一個應用程序，它要求將日志消息記錄到數據庫中。 我在log4j屬性文件中使用了EnhancedPattenrLayout將消息記錄到DB中。 但是我在將異常堆棧跟蹤記錄到db中時出錯

“ com.microsoft.sqlserver.jdbc.SQLServerException：字符串或二進制數據將被截斷。”

請注意，我故意給了錯誤的smtp，以檢查它是否將異常堆棧跟蹤記錄到DB中。

請在這方面幫助我。

在這里找到log4j.properties文件

Answer 1

您的列太小而無法容納要記錄的數據，因此它不會引發數據截斷而是拋出異常。 找出問題所在的列並將其擴大。

Answer 2

我遇到了問題，並增加了LOGS1表的THROWABLE列的長度。
