（转）使用jdk的xjc命令由schema文件生成相应的实体类

背景：在webservice的开发过程中涉及到这一知识点，又必要来学习一下。

1 根据编写的schema来生成对应的java实体

1.1 实战

xcj命令有schema文件生成Java实体类

1、使用方法
xjc fileName.xsd -d 生成java实体类的目录 -p 生成的包名

2. eg： xjc catalog.xsd -d d: est -p com.xjc.bean

xjc szfs.tws.biz.info.billchange.xsd -d E:Work直连接口改造文档接口直连接口schemainfo -p szfs.tws.biz.entity.info.billchange

xjc szfs.tws.biz.info.billchange.xsd:
