查了很多地方都不对，请高手解决。

Answer 1

我用你的这段连数据库的代码。连上mysql没问题啊。

Answer 2

楼主可以看看这个：
http://topic.csdn.net/u/20080606/15/4f150a8d-c88d-47c0-96a8-9dc4e8f2ec7b.html

Answer 3

再补充一句，这个错在启动tomcat时是没有的，要进页面执行时才会报出来。

Answer 4

<property name="breakAfterAcquireFailure">
<value>true</value>
</property>
设置成false试试另外可能是jar包问题

Answer 5

换个c3p0的JAR包试试，昨天我连上查询数据库都正常的。

Answer 6

好像C3P0   H3就不支持了吧..

Answer 7

<property name="breakAfterAcquireFailure">
<value>true</value>改成false试试。调试看看在哪儿连接失败。

Answer 8

按楼上的改了报的错变成了：

at java.lang.Thread.run(Thread.java:619)我断点进入看是在this.getHibernateTemplate().save(user);这个东西保存时出的异常。

Answer 9

楼上的大大请说清楚，我如用dhcp完全成正，那c3p0又和哪个包冲突呢？
