🥳🥳Welcome Huihui's Code World ! !🥳🥳

一.导读

二.详细操作步骤 

 1.右击项目处，点击import

 2.选择所要导入的项目所在路径

 3.导入项目完毕之后，需要检查是否有错误

 4.若报错，则检查配置的文件是否出现了问题

 5.将报错的文件移除掉

 6.重新配置一个文件（注意版本）

 7.项目不报错之后，我们来看一下数据库辅助类​编辑

 8.核对账号密码的信息

 9.再选择需要导入的对应数据库脚本

10.选择运行的jsp界面即可，若成功运行，则没有问题

11.我们再参照这个项目中的代码，完成一个简单的增删改查

entity

dao

servlet

运行结果

一.导读

上篇我们已经详细介绍了开发工具eclipse，也说明了eclipse的基本使用，那么我们这篇来详细讲述一下怎么导入项目

entity

package com.wh.entity;public class Cat {
int cid;
String cname;
int age;public Cat() {// TODO Auto-generated constructor stub
}public Cat(int cid, String cname, int age) {super();this.cid = cid;this.cname = cname;this.age = age;
}public int getCid() {return cid;
}public void setCid(int cid) {this.cid = cid;
}public String getCname() {return cname;
}public void setCname(String cname) {this.cname = cname;
}public int getAge() {return age;
}public void setAge(int age) {this.age = age;
}@Override
public String toString() {return "Cat [cid=" + cid + ", cname=" + cname + ", age=" + age + "]";
}}

dao

package com.wh.dao;import java.util.List;import com.zking.util.BaseDao;
import com.zking.util.PageBean;
import com.zking.util.StringUtils;public class CatDao extends BaseDao<Cat>{public List<Cat> list(Cat cat,PageBean pageBean) throws Exception{String sql = "select * from t_mvc_cat where 1 =1 ";String title = cat.getCname();int id = cat.getCid();if(StringUtils.isNotBlank(title)) {sql += " and title like '%"+title+"%'";}if(id != 0) {sql += " and cid = "+id;}return super.executeQuery(sql, Cat.class, pageBean);}public void add(Cat cat) throws Exception {String sql = "insert into t_mvc_cat(cid,cname,age) values(?,?,?)";super.executeUpdate(sql, cat, new String[] {"cid","cname","age"});}public void delete(Cat cat) throws Exception {String sql = "delete from t_mvc_cat where cid = ?";super.executeUpdate(sql, cat, new String[] {"cid"});}public void edit(Cat cat) throws Exception {String sql = "update t_mvc_cat set cname = ?,age = ? where cid = ?";super.executeUpdate(sql, cat, new String[] {"cname","age","cid"});}
}

servlet

package com.wh.web;import java.util.List;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;import com.wh.dao.CatDao;
import com.zking.entity.Cat;
import com.zking.framework.ActionSupport;
import com.zking.framework.ModelDriver;
import com.zking.util.PageBean;public class CatAction extends ActionSupport implements ModelDriver<Cat>{public Cat cat = new Cat();public CatDao catDao = new CatDao();@Overridepublic Cat getModel() {return cat;}public String list(HttpServletRequest req, HttpServletResponse resp) {
//		查数据库的PageBean pageBean = new PageBean();pageBean.setRequest(req);try {List<Cat> list = catDao.list(cat, pageBean);req.setAttribute("cats", list);req.setAttribute("pageBean", pageBean);} catch (Exception e) {e.printStackTrace();}return "list";}public String add(HttpServletRequest req, HttpServletResponse resp) {try {catDao.add(cat);} catch (Exception e) {e.printStackTrace();}return "toList";}public String delete(HttpServletRequest req, HttpServletResponse resp) {try {catDao.delete(cat);} catch (Exception e) {e.printStackTrace();}return "toList";}public String edit(HttpServletRequest req, HttpServletResponse resp) {try {catDao.edit(cat);} catch (Exception e) {e.printStackTrace();}return "toList";}public String toEdit(HttpServletRequest req, HttpServletResponse resp) {if(cat.getCid()!= 0) {try {List<Cat> list = catDao.list(cat, null);req.setAttribute("c", list.get(0));} catch (Exception e) {e.printStackTrace();}}return "toEdit";}
}
