我在standalone.xml 文件中为具有相同名称的类别定义了两个处理程序，如下所示 

<logger category="ab.cd" use-parent-handlers="false">
            <level name="DEBUG" />
            <handlers>
                <handler name="abDebug" />
            </handlers>
        </logger>
<logger category="ab.cd" use-parent-handlers="true">
                <level name="WARN" />
                <handlers>
                    <handler name="abWarning" />
                </handlers>
            </logger>

但是当我尝试运行 jboss 7 时出现异常

所以，我想知道这可能有两个相同类别的记录器吗？如果不是，那么在这种情况下如何将数据发送到两个不同的处理程序？

您不能定义两个具有相同类别的记录器。记录器如何知道它应该使用哪个级别？您最好使用一个没有设置级别的记录器，并使用处理程序来设置您想要记录的级别。

类似于以下内容：

<file-handler name="abDebug" auto-flush="true">
    <level name="DEBUG"/>
    <file relative-to="jboss.server.log.dir" path="abDebug.log"/>
    <append value="true"/>
</file-handler>
<file-handler name="abWarning" auto-flush="true">
    <level name="WARN"/>
    <file relative-to="jboss.server.log.dir" path="abWarning.log"/>
    <append value="true"/>
</file-handler>

<logger category="ab.cd">
    <handlers>
        <handler name="abDebug" />
        <handler name="abWarning" />
    </handlers>
</logger>
