Question

我正在使用Hibernate和Java网络应用程序，我想将限制设置为SQL Server 2005连接池大小。据我所知，我必须使用连接字符串。我可以在hibernate.properties或hibernate.cfg.xml中指定吗？是否有必填字段，或者我可以指定Max Pool Size？

修改我想重现一个来自生产机器的错误：

如果您使用例如c3p0，则可以按maxPoolSize属性配置池大小，例如：

<bean id="datasource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
    <property name="driverClass" value="...." />
    <property name="jdbcUrl" value="..."/>
    <property name="maxPoolSize" value="..." />
</bean>
