jackson处理标签中带属性的xml
用jackson相关包把如下xml转为java bean
<Configuration shutdownHook="disable" packages="org.ironrhino.core.log4j">
<Properties>
<Property name="app.home">/tmp/app</Property>
<Property name="port.http"></Property>
</Properties>
<Appenders>
<Console name="CONSOLE" target="SYSTEM_OUT">
<ThresholdFilter level="${sys:console.logger.level}"/>
<PatternLayout pattern="%style{%d %25.25t %60.60c{1.}}{cyan} %highlight{%p %m%n}" noConsoleNoAnsi="true"/>
</Console>
<File name="DEBUG" fileName="${sys:app.home}/logs/${sys:port.http}/application-debug.log">
<PatternLayout pattern="%d %c %t%X{request}%X{url} %p %m%n%th{10}" charset="UTF-8"/>
</File>
<RollingFile name="APPLICATION" fileName="${sys:app.home}/logs/${sys:port.http}/application.log" filePattern="${sys:app.home}/logs/${sys:port.http}/application.log.%d{yyyy-MM-dd}">
