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: \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.tws.biz.entity.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。
