hibernate配置：连接在应用程序端不活动时超时

时间：2017-08-11 16:24:22

标签： java hibernate configuration connection

我正在使用hibernate进行数据库事务。我们的应用程序每次第一次执行流程时都会出错，我们每天都会遇到错误，并发布我们停止解决这些问题。

所以我的第一个疑问仍然是我们以某种方式使用已经超时的空闲连接。很公平，我们总是可以使用hibernate.cfg.xml来处理这个部分。

所以我偶然发现了这样做的各种方法，即通过在我们的hibernate配置中添加以下任何参数，我们应该能够解决相同的问题，但是这些都没有解决我在这里避免空闲连接的目的＆＃34;连接超时＆＃34;每天开始时失败：

<property name="hibernate.c3p0.testConnectionOnCheckout">true</property>
<property name="hibernate.c3p0.idle_test_period">30</property>

我得到的错误如下：

这是关于与数据库的连接的建立。您是否尝试增加登录时间？

<property name="hibernate.c3p0.timeout">180</property>
