Spring 带弹簧的注入式记录器4J

我有一个Spring2.5WebApp，其中包含以下web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

version="2.4">

</servlet-mapping>

    <welcome-file>index.html</welcome-file>
</welcome-file-list>

</web-app>

我希望登录类UserDAO会登录到文件appender，但事实并非如此。文件已创建，但为空。根追加器工作正常。

我做错了什么？

在services-context.xml文件中，尝试将“myLog”bean的“logName”属性设置为“com.bla.database”。这应该与log4j.xml配置文件中定义的记录器名称相匹配。

另一种方法是将日志记录视为一个横切关注点，并使用方面进行处理。您可以声明性地应用标准的Spring拦截器。

也有，我自己也很喜欢Aspect。我想这样做，但我在Spring方面的专业知识还不够。事实上，我甚至不知道我在维基百科上读到的东西有什么不同：）你把commons日志和Log4j混在一起了。Te myLog变量应为org.apache.log4j.Logger类型，并且应为静态变量。这使得Spring很难注入它。。。我不知道是否有办法注入静态变量。

    <bean id="mylog"
    class="org.springframework.beans.factory.config.CommonsLogFactoryBean">
    <property name="logName" value="mylog" />
</bean>

    <bean id="user" class="com.acotel.msp.database.UserDAO" >
    <property name="mylog" ref="mylog" />
    <property name="jsonClient" ref="jsonClient" />
</bean>
