是 InitSqlSessionListener implements ServletContextListener
类里面的方法执行之后出现警告
public void contextDestroyed(ServletContextEvent sce) {
System.out.println("容器销毁中.....");
// 关闭SqlSessionFactoty对象 并将threadlocal释放
SqlSessionFactoryUtils.close();
}
这个是SqlSessionFactoryUtils的close方法
public static void close() {
SqlSession session = threadLocal.get();
if (session != null) {
session.close();
threadLocal.set(null);
}
}
容器销毁中.....
