c3p0-config.xml 里边内容的配置

配置如下：

<?xml version="1.0" encoding="UTF-8"?><c3p0-config>     <default-config>         <property name="driverClass">com.mysql.jdbc.Driver</property>          <property name="jdbcUrl">jdbc:mysql://localhost:3306/productStore</property>         <property name="user">root</property>         <property name="password">123456</property>         <property name="initialPoolSize">10</property>         <property name="maxIdleTime">30</property>          <property name="maxPoolSize">100</property>         <property name="minPoolSize">10</property>         <property name="maxStatements">200</property>      </default-config> </c3p0-config>

改一下数据库就行了。
