由Spring管理的c3p0

Question

有人知道如何制作：

com.mchange.v2.c3p0.management.ManagementCoordinator=com.mchange.v2.c3p0.management.NullManagementCoordinator

使用Spring而不是c3p0.properties文件？

Answer 1

您可以定义以下bean：

<bean id="sysProps" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
  <property name="targetClass"><value>java.lang.System</value></property>
  <property name="targetMethod"><value>setProperty</value></property>
  <property name="arguments">
    <list>
      <value>com.mchange.v2.c3p0.management.ManagementCoordinator</value>
      <value>com.mchange.v2.c3p0.management.NullManagementCoordinator</value>
    </list>
  </property>
</bean>

然后，您的数据源bean定义应包含depends-on属性，如下所示：

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close" depends-on="sysProps">
