目前的專案日誌中經常出現一串日誌會佔用好幾行，目前使用者到所以想不列印這些：

2017-07-08 11:35:39,358 DEBUG SaveLogThread org.springframework.transaction.support.TransactionSynchronizationManager - Removed value [org.springframework.jdbc.datasource.ConnectionHolder@7442c5c3] for key [{

百度了一下沒有找到設定 traceEnabled的地方

• 方法1：
  在配置檔案裡把所有spring日誌全都關閉，應該還可以更具體點

log4j.logger.org.springframework = error

• 方法2：
  通過與其他沒有此類日誌的專案對比，發現加上commons-logging1.1.2jar包就可以了
