先简单说下前三种方式：

DOM方式：个人理解类似.net的XmlDocument，解析的时候效率不高，占用内存，不适合大XML的解析；

SAX方式：基于事件的解析，当解析到xml的某个部分的时候，会触发特定事件，可以在自定义的解析类中定义当事件触发时要做得事情；个人感觉一种很另类的方式，不知道.Net体系下是否有没有类似的方式？

StAX方式：个人理解类似.net的XmlReader方式，效率高，占用内存少，适用大XML的解析；

不过SAX方式之前也用过，本文主要介绍JAXB，这里只贴下主要代码：import java.util.ArrayList;

import java.util.List;

} else if (currentConfigSection.equalsIgnoreCase("InterfaceConfigItems")) {

interfaceConfigList.add(new InterfaceConfigItem(attributes));

}

}import java.lang.reflect.Field;

}

} catch (IllegalArgumentException e) {

break;

}

Field[] fields = cls.getDeclaredFields();

} catch (IllegalArgumentException e) {

e.printStackTrace();

} catch (IllegalAccessException e) {

e.printStackTrace();

}

}

return result;

}

/**

}

下面重点介绍一下最方便的:JAXB(Java Architecture for XML Binding)

这里用比较复杂的移动BatchSyncOrderRelationReq接口XML做为示例(感觉能解这个大家基本上够用了)，报文格式如下(SvcCont里的CDATA内容是报文体，太恶心了)：<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
