已關閉的連接：獨立jvm上的tomcat數據源（org.apache.tomcat.jdbc.pool.DataSource）

對於具有多線程的獨立jar（spring批處理），我得到了以下配置的關閉連接問題。已關閉的連接：獨立jvm上的tomcat數據源（org.apache.tomcat.jdbc.pool.DataSource）

堆棧跟蹤：

異常說，你有一些代碼不返回連接放回池中（通過關閉它）。

底部堆棧跟蹤的顯示，你把從池

com.abcd.package.dao.proc.BaseStoredProc.executeStoredProc(BaseStoredProc.java:81) at

也許缺少最後關閉連接該連接？
