用 Spring 初始化 Log4J? [英] Initializing Log4J with Spring?

问题描述

我有一个 Web 应用程序，它使用 Spring 的 Log4jConfigurer 类来初始化我的 Log4J 日志工厂.基本上，它使用类路径之外的配置文件初始化 Log4J.

I have a web app that uses Spring's Log4jConfigurer class to initialize my Log4J log factory. Basically it initializes Log4J with a config file that is off the class path.

这里是配置:

<bean id="log4jInitializer" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean" depends-on="sbeHome">
    <property name="targetClass" value="org.springframework.util.Log4jConfigurer" />
    <property name="targetMethod" value="initLogging" />
    <property name="arguments">
        <list>
            <value>#{ MyAppHome + '/conf/log4j.xml'}</value>
        </list>
    </property>
</bean>

但是我在应用程序启动时收到此错误:

However I get this error at application startup:

log4j:WARN 找不到记录器的附加程序

和大量 Spring 应用程序上下文初始化消息被打印到控制台.我认为这是因为 Spring 在有机会初始化我的记录器之前正在做初始化我的应用程序的工作.以防万一，我在 Log4J 之上使用 SLF4J.

and tons of Spring application context initialization messages are printed to the console. I think this is because Spring is doing work to initialize my application before it has a chance to initialize my logger. In case it matters, I am using SLF4J on top of Log4J.

有什么方法可以让我的 Log4jConfigurer 成为第一个初始化的 bean?或者有其他方法可以解决这个问题吗?

Is there some way I can get my Log4jConfigurer to be the first bean initialized? or is there some other way to solve this?

推荐答案

你可以在 web.xml 而不是 spring-context.xml 中配置你的 Log4j 监听器

You could configure your Log4j listener in the web.xml instead of the spring-context.xml

<context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>/WEB-INF/classes/log4j.web.properties</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

所以它在春天开始之前就结束了.

So it is up before Spring starts.
