测试了一下就是卡在executeBatch ( )那句话了，已经标出来了，求助

不知道你的未执行是什么意思，不过从代码上猜测可能是抛异常了，建议你在各种catch中将异常信息的log输出，看看是断在那个环节了。

con.setAutoCommit ( false );这句话是什么意思。
这是开启或关闭自动提交模式：

con.setAutoCommit(false) ;
 con.setAutoCommit(true) ;  
一旦关闭了自动提交，除非通过调用 commit() 显式地告诉它提交语句，否则无法提交 SQL 语句（即，数据库将不会被持久地更新）。在提交之前的任何时间，我们都可以调用 rollback() 回滚事务，并恢复最近的提交值（在尝试更新之前）。

给的建议是把这个con.setAutoCommit(false) 改为con.setAutoCommit(true);
