搭个ssh环境搭了三天，终于搭好了（下）

1 dao文件夹下

IImgDao.java

package dao;

import java.util.List;

import bean.Img;

public interface IImgDao {
public boolean saveNewImg(Img img);
public List findAll();
public Img findByImgId(Integer id);
public void removeImg(Img img);
}

ImgDAO.java

package dao;

import java.util.ArrayList;
import java.util.List;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import bean.Img;
import dao.IImgDao;

public class ImgDAO extends HibernateDaoSupport implements IImgDao {

public List findAll() {
try {
return this.getHibernateTemplate().find("from Img img");
} catch (Exception ex) {
return new ArrayList();
}
}

public Img findByImgId(Integer id) {
return (Img) this.getHibernateTemplate().get(Img.class, id);
}

public void removeImg(Img img) {

this.getHibernateTemplate().delete(img);
}

public boolean saveNewImg(Img img) {
this.getHibernateTemplate().save(img);
return false;
}

}

2 service文件夹下

IImgService.java

package service;

import java.util.List;

import bean.Img;

public interface IImgService {
public abstract boolean saveNewImg(Img img);
public abstract List findAll();
public abstract Img findByImgId(int id);
public abstract void removeImg(Img img);
}

ImgService.java

package service;

import java.util.List;
import dao.IImgDao;
import bean.Img;
import service.IImgService;

public class ImgService implements IImgService{

public IImgDao imgDAO;

public IImgDao getImgDAO() {
return imgDAO;
}

public void setImgDAO(IImgDao imgDAO) {
this.imgDAO = imgDAO;
}

public List findAll() {
return this.getImgDAO().findAll();
}

public Img findByImgId(int id) {
return this.getImgDAO().findByImgId(new Integer(id));
}

public void removeImg(Img img) {
this.getImgDAO().removeImg(img);
}

public boolean saveNewImg(Img img) {

return this.getImgDAO().saveNewImg(img);
}

}

3 action文件夹下

SaveImgAction.java

package action;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts2.ServletActionContext;

import service.ImgService;

import bean.Img;

import com.opensymphony.xwork2.ActionSupport;

public class SaveImgAction extends ActionSupport{
public	ImgService imgService;
public String execute() {
HttpServletRequest request = ServletActionContext.getRequest();
request.setAttribute("imgpath", "9896648");
Img img=new Img();
img.setImgPath("dongshen");
imgService.saveNewImg(img);
return SUCCESS;

}

public ImgService getImgService() {
return imgService;
}
public void setImgService(ImgService imgService) {
this.imgService = imgService;
}
}

4 bean

Img.java

package bean;

public class Img {
public int id;
public String imgPath;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getImgPath() {
return imgPath;
}
public void setImgPath(String imgPath) {
this.imgPath = imgPath;
}
}
