4. 具体代码
UserDao.java
package com.sun.dao;
import com.sun.orm.User;
public interface UserDao {
public User getUserByName(String name);
}
UserDaoImpl.java
package com.sun.dao.impl;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import com.sun.dao.UserDao;
import com.sun.orm.User;
public class UserDaoImpl extends HibernateDaoSupport implements UserDao{
public User getUserByName(String name) {
// TODO Auto-generated method stub
String hql = "from User as u where u.name=?";
return (User) getHibernateTemplate().find(hql,name).get(0);
}
}
UserService.java
package com.sun.service;
import com.sun.orm.User;
public interface UserService {
public User getUserByName(String name);
}
UserServiceImpl.java
package com.sun.service.impl;
import com.sun.dao.UserDao;
import com.sun.orm.User;
import com.sun.service.UserService;
public class UserServiceImpl implements UserService{
private UserDao userDao;
public UserDao getUserDao() {
return userDao;
}
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
public User getUserByName(String name) {
// TODO Auto-generated method stub
return userDao.getUserByName(name);
}
}
UserAction.java
package com.sun.action;
import java.util.HashMap;
import java.util.Map;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import net.sf.json.JSONObject;
import org.apache.struts2.ServletActionContext;
import com.opensymphony.xwork2.ActionSupport;
import com.sun.orm.User;
import com.sun.service.UserService;
public class UserAction extends ActionSupport{
private UserService userService;
private String name;
private String password;
private User user;
public UserService getUserService() {
return userService;
}
public void setUserService(UserService userService) {
this.userService = userService;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public String execute(){
System.out.println("name is " + name);
Map map = new HashMap();
user = userService.getUserByName(name);
System.out.println("password is " + user.getPassword());
map.put("result", "true");
return "result";
}
}
其中User.java和User.hbm.xml用MyEclipse可以自动生成,若用Eclipse可以自己编写
MyEclipse自动生成方法:
切换到MyEclispe Database Explore视图,选择要持久化的数据库表
提示:附件EclipseSSH.rar为SSH的一个例子,ssh.rar为ssh所需要的jar包
