Proxool连接池

proxool.xml

可以配置多个数据源。

<?xml version="1.0" encoding="UTF-8"?>

web.xml

    <!--加载配置文件-->
    <servlet>
        <servlet-name>proxoolServletConfigurator</servlet-name>
        <servlet-class>
            org.logicalcobwebs.proxool.configuration.ServletConfigurator
        </servlet-class>
        <init-param>
            <param-name>xmlFile</param-name>
            <param-value>WEB-INF/classes/jdbcproxool.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <!--proxool监控-->
    <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>/proxoolAdmin</url-pattern>
    </servlet-mapping>

这里org.logicalcobwebs.proxool.configuration.ServletConfigurator加载一定要早于org.springframework.web.context.ContextLoaderListener。

Spring-Dao.xml

spring中使用proxool作为spring jdbc template的数据源。

    <!--spring jdbc template-->
    <!--datasource-->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="org.logicalcobwebs.proxool.ProxoolDriver"/>
        <property name="url" value="proxool.asset"/>
    </bean>
    <!--jdbcTemplate使用datasource-->
    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource" ref="dataSource"/>
    </bean>
    <!--事务-->
    <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>
    <!--事务注解-->
    <tx:annotation-driven transaction-manager="txManager"/>

启动时报错
