这个hibernate的c3p0配置：
<property   name= "hibernate.c3p0.max_size "> 3000 </property>

<property   name= "hibernate.c3p0.min_size "> 5 </property>

<property   name= "hibernate.c3p0.timeout "> 300 </property>

<property   name= "hibernate.c3p0.max_statements "> 100 </property>

<property   name= "hibernate.c3p0.idle_test_period "> 120 </property>

<property   name= "hibernate.c3p0.acquire_increment "> 50 </property>
