（转）使⽤jdk的xjc命令由schema⽂件⽣成相应的实体类背景：在webrvice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 ⽣成的包名衔接
2. eg： xjc catalog.xsd -d d: \test -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schema\info -p szfs.ity.info.billchange
xjc szfs.tws.biz.info.billchange.xsd:

1.2 扩展
⾸先确保计算机已经安装了jdk，且在环境变量中配置了jdk路径。
我的计算机安装的是1.7，就以这个为例吧！
1.进⼊dos窗⼝
1.指定某⼀个xsd⽂件⽣成指定名称的类
进⼊xsd⽂件所在⽬录，我的在D盘，所以我 D：进⼊D盘
然后开始执⾏下⾯语法（xxxxx.xsd 为要⽣成的xsd⽂件 xxxxx为⽬录）xjc xxxxx.xsd -p xxxxx.bean;
2.将所有的xsd⽂件⽣成，并指定⽣成⽬录
xjc *.xsd -p com.cpp.interconnection.bean
然后完毕后，⽬录和类已经全部⽣成，⼤功搞成。1
