SSH2框架使用(二)

二、编码

SSH2项目的目录如下：

SSH2

  -cn.com.ssh2.action #Struts2版本

     -UserAction.java

  -cn.com.ssh2.bo

     -User.java    用户对象

     -User.hbm.xml 把用户对象转换成数据库中的字段对应的映射关系文件

  -cn.com.ssh2.dao #Hibernate

     -BaseHbnDao.java

     -UserDao.java

  -cn.com.ssh2.service #Spring

     -IuserService.java

     -UserServiceImpl.java

  -struts.xml #Struts2的配置文件

  -web

    -user.jsp

    -WEB-INF 

      -lib

      -applicationContext.xml

      -dispatcher-servlet.xml

      -web.xml

具体各文件内容如下:

1、UserAction.java

/** * AddUserAction.java. */ package cn.com.ssh2.action; import cn.com.ssh2.bo.User; import cn.com.ssh2.service.IUserService; import com.opensymphony.xwork2.Action; import com.opensymphony.xwork2.ActionSupport; /** * <p> * 类描述:. * </p> * * * <p> * 版权所有:**公司(c) 2009. * </p> * * @author jianglq * * @version 4.0 * @data 2009-5-2 * @time 下午04:41:43 */ public class UserAction extends ActionSupport { /** * serialVersionUID. */ private static final long serialVersionUID = 1L; /** * 对用户信息进行操作. */ private IUserService iUserService; private User user=new User(); public String save() { try { iUserService.save(user); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return Action.SUCCESS; } public void setiUserService(IUserService iUserService) { this.iUserService = iUserService; } public User getUser() { return user; } public void setUser(User user) { this.user = user; } }
