对于具有多线程的独立 jar(spring 批处理)，我遇到以下配置的关闭连接问题。
堆栈跟踪:

最佳答案
异常表示您有代码不会将 Connection 返回到池中(通过关闭它)。
堆栈跟踪的底部显示了您从池中获取该连接的位置
com.abcd.package.dao.proc.BaseStoredProc.executeStoredProc(BaseStoredProc.java:81) at
也许最终缺少关闭连接？
关于java - 在独立 jvm 上关闭连接 : tomcat data source (org. apache.tomcat.jdbc.pool.DataSource)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34137350/
