使用log4j.xml时java-log4j警告消息

我正在尝试将我的log4j.properties转换为log4j.xml,因为我需要使用一些过滤器功能.当我启动应用程序时,我收到一堆警告,我不确定如何解决它们：

log4j:WARN Continuable parsing error 4 and column 69
log4j:WARN Attribute "threshold" for element type "log4j:configuration" has a default value and must be specified in a standalone document.
log4j:WARN Continuable parsing error 4 and column 69
log4j:WARN Attribute "debug" for element type "log4j:configuration" has a default value and must be specified in a standalone document.
log4j:WARN Continuable parsing error 4 and column 69
log4j:WARN Attribute "reset" for element type "log4j:configuration" has a default value and must be specified in a standalone document.
log4j:WARN Continuable parsing error 20 and column 23
log4j:WARN The content of element type "log4j:configuration" must match "(renderer*,appender*,plugin*,(category|logger)*,root?,(categoryFactory|loggerFactory)?)".
log4j:WARN Unrecognized element param

我只是尝试使用一个非常简单的log4j.xml文件：

figuration SYstem "log4j.dtd">
figuration xmlns:log4j="http://jakarta.apache.org/log4j/">
    aram name="Threshold" value="INFO"/>
        aram name="ConversionPattern" value="%-5p | %d{MM-dd-yyyy HH:mm:ss.SSS} | %t | %c(%L) - %m%n"/>
        figuration>

我在这里错过了什么？谢谢！

最佳答案

粗略地说,独立属性声明信息集不受文档外的任何内容的影响.但是,在这种情况下,情况并非如此,因为属性具有在外部DTD中指定的默认值.
