S2SH+proxool JNDI 数据源

Struts2 Spring2.5 Hibernate3.2 proxool9.1 tomcat6.18配置整合

网上很多朋友讲到了hibernate怎么用proxool

单独的怎么配置proxool,却很少把struts2和spring2还有hibernate整合起来的.花了一天的时候,才把配置整成功,分享出来给大家,希望可以少走弯路吧.

 

这里和大家讲一下,为什么要用tomcat来启动数据库连接池.除了资源控制一块,还有一个很大的原因是因为struts2要求spring的加载方式为<listener>

而spring会整合hibernate,在实例化的时候,会去加载proxool数据链接池.

因为proxool的加载方式是通过<servlet>方式来的,加载顺序在<listener>之后,也就是spring的后面加载.这样加载会不成功.

所以proxool的加载只能是在spring之前加载.网上有一个网友把proxool的加载方式改成了 <listener> 放在spring之前加载,这样太麻烦了,还要改源码.

于是这个方式成本就最低了.

当然,也有网友提到

写道

直接在application.xml配上
<prop key="hibernate.proxool.xml">proxool.xml</prop>

 以上引用,我配置后,并没有作用.估计那位网友使用的版本和我的不同吧.反正我试了半天是没有成功.

 

 

tomcat/conf/context.xml 配置proxool.

加在

</Context>

 元素的前面 proxool的配置元素,就不多讲了,网上有很多详细的介绍.这里给大家一个链接:http://wallimn./blog/486550

<Resource name="jdbc/mysql"
    auth="Container"
    type="javax.sql.DataSource"
    factory="org.logicalcobwebs.proxool.ProxoolDataSource"
    proxool.alias="DBPool"
    user="root"
    password="root"
    delegateProperties="foo=bar"
    proxool.jndi-name="mysqljndi"
    proxool.driver-url="jdbc:mysql://127.0.0.1:3306/webgame?characterEncoding=utf-8"
    proxool.driver-class="com.mysql.jdbc.Driver"
    proxool.house-keeping-sleep-time="40000"
    proxool.house-keeping-test-sql="SELECT ''"
    proxool.maximum-connection-count="100"
    proxool.minimum-connection-count="20"
    proxool.maximum-connection-lifetime="18000000"
    proxool.simultaneous-build-throttle="20"
    proxool.recently-started-threshold="40000"
    proxool.overload-without-refusal-lifetime="50000"
    proxool.maximum-active-time="60000"
    proxool.verbose="true"
    proxool.trace="true"
    proxool.fatal-sql-exception="Fatal error"
    proxool.prototype-count="2"
    proxool.statistics-log-level="ERROR
    />

 现在就不需要单独的来配置proxool.properies 和proxool.xml了.

记得把proxool-0.9.1.jar和proxool-cglib.jar包复制到tomcat/lib文件夹下,否则会报找不到

org.logicalcobwebs.proxool.ProxoolDataSource

错误.把包放到自己项目下的话,会报这个错,但是也可以运行的.

 

接下来是配置web.xml

以上配置基本解决了启动方面的问题.
