將BasicDataSource配置爲web.xml中的bean

Question

我試圖將org.apache.commons.dbcp.BasicDataSource配置爲使用tomcat 6的tomcat項目下的web.xml中的bean。（這是使用tomcat的red5，我們可以忽略主服務器實際上是RED5，因爲我實際上運行在端口5080的jsp文件，也不要連接到RED5直接使用RTMP協議）

我的web.xml：

<?xml version="1.0" encoding="ISO-8859-1"?> 
<web-app 
xmlns="http://java.sun.com/xml/ns/j2ee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/ j2ee/web-app_2_4.xsd" 
version="2.4">

<bean id="placeholderConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> 
    <property name="location" value="/WEB-INF/red5-web.properties" /> 
</bean> 

    <bean id="idDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> 
      <property name="driverClassName"><value>${db.driver}</value></property> 
      <property name="url"><value>${db.url}</value></property>

      <property name="maxActive"><value>10</value></property> 
      <property name="maxIdle"><value>10</value></property> 
    </bean> 


</web-app> 

我red5-web.properties ：

webapp.contextPath=/myapp 
webapp.virtualHosts=* 
db.driver=com.mysql.jdbc.Driver 
db.url=jdbc:mysql://127.0.0.1:3306/dbname 
db.username=user 
db.password=pass 

tomcat是否自動搜索WEB-INF/web.xml進行配置？

爲什麼我不會在創建idDataSource時遇到任何相關的錯誤？

我真的沒有任何線索如何查明或調試問題。 任何援助將不勝感激。

謝謝！

我不知道任何關於Red5的，但好像你試圖把Spring bean的直接內web.xml，這是不對的。你可以創建一個單獨的Spring配置文件，該文件將被Springs的ContextLoaderListener選中。首先，添加到您的web.xml：

<listener> 
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
</listener> 

比/WEB-INF下創建applicationContext.xml文件：

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> 

    <bean id="placeholderConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> 
     <property name="location" value="/WEB-INF/red5-web.properties" /> 
    </bean> 

    <bean id="idDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> 
     <property name="driverClassName"><value>${db.driver}</value></property> 
     <property name="url"><value>${db.url}</value></property> 
     <property name="username"><value>${db.username}</value></property> 
     <property name="password"><value>${db.password}</value></property> 
     <property name="poolPreparedStatements"><value>true</value></property> 
     <property name="maxActive"><value>10</value></property> 
     <property name="maxIdle"><value>10</value></property> 
    </bean> 

</beans> 

當然所有<bean/>聲明應該從web.xml消失。

退一步：看着this文件好像Red5的使用名​​爲red5-web.xml文件，請仔細去通過這個文檔。
