tomcat与mysql连接隔段时间没有访问总是自动断开解决方法

 

在 hibernate.cfg.xml 中加入如下代码

<property name="hibernate.connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property>
<property name="hibernate.c3p0.min_size">8</property>
<property name="hibernate.c3p0.max_size">200</property>
<property name="hibernate.c3p0.timeout">600</property>
<property name="hibernate.c3p0.max_statements">0</property>
<property name="hibernate.c3p0.idle_test_period">60</property>
<property name="hibernate.c3p0.acquire_increment">2</property>
<property name="hibernate.c3p0.validate">true</property>
