Hibernate配置连接池大小 [英] Hibernate config connection pool size

问题描述

为什么在连接池的hibernate配置文件中设置10？ size = 1是为size.why需要增加尺寸吗？

 <！DOCTYPE hibernate-configuration PUBLIC 
 -  // Hibernate / Hibernate配置DTD 3.0 // EN
http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd\"> 
 
< hibernate-configuration> 
 
< session-factory> 
 .... 
 
< property name =connection.pool_size> 10< / property> 
 
 .... 
< / session-factory> 
 
< / hibernate-configuration> 
  

解决方案

从 Hibernate API 文档。

然而，Hibernate自己的连接池算法相当简陋。它旨在帮助您开始使用，不适用于生产系统，甚至不适用于性能测试。您应该使用第三方池以获得最佳性能和稳定性。只需将hibernate.connection.pool_size属性替换为连接池特定的设置即可。这将关闭Hibernate的内部池。例如，您可能想使用c3p0。

connection.pool_size 表示连接池的最大数量。所以最好把它保持在逻辑上。这取决于你的应用程序和数据库能处理多少。 10 是一个合理的计数，通常用于大多数情况。

why set 10 in hibernate config file for connection pooling ? size = 1 is built in size.why need to increase size ?

<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

    <session-factory>
     ....

       <property name="connection.pool_size">10</property>

     ....
    </session-factory>

</hibernate-configuration>

解决方案

From the Hibernate API Docs.

Hibernate's own connection pooling algorithm is, however, quite rudimentary. It is intended to help you get started and is not intended for use in a production system, or even for performance testing. You should use a third party pool for best performance and stability. Just replace the hibernate.connection.pool_size property with connection pool specific settings. This will turn off Hibernate's internal pool. For example, you might like to use c3p0.

connection.pool_size indicates the maximum number of pooled connections. So it is better to keep it at a logical count. It depends on your application and DB how much it can handle. 10 is a reasonable count that will typically used as it is sufficient for most cases.
