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>
<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.iteye.com/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
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>classpath:log4j.properties</param-value> </context-param> <filter> <filter-name>struts2</filter-name> <filter-class> org.apache.struts2.dispatcher.FilterDispatcher </filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 加载数据连接池及监控数据连接池功能 --> <!-- 由于已经通过tomcat的jndi来加载了数据连接,所以这样里以不需要了 <servlet> <servlet-name>ServletConfigurator</servlet-name> <servlet-class> org.logicalcobwebs.proxool.configuration.ServletConfigurator </servlet-class> <init-param> <param-name>propertyFile</param-name> <param-value> WEB-INF\classes\proxool.properties </param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> --> <servlet> <servlet-name>Admin</servlet-name> <servlet-class> org.logicalcobwebs.proxool.admin.servlet.AdminServlet </servlet-class> </servlet> <servlet-mapping> <servlet-name>Admin</servlet-name> <url-pattern>/proxool.admin</url-pattern> </servlet-mapping> <!-- 加载spring文件 --> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext.xml</param-value> </context-param> </web-app>

以上配置基本解决了启动方面的问题.
