package com.hsj.domain;
public class Menu {
private int id; //菜单id
private String name; //菜单名
private String url; //菜单链接的网址
private String checked; //菜单是否被选中
private String icon; //菜单图标
private int parent_id; //当前菜单的父节点id
public Menu(){}
public Menu(int id, String name, String url, String checked, String icon,int parentId) {
this.id = id;

public int getId() {

TreeDTD.java
package com.hsj.domain;
import java.util.HashMap;
import java.util.Map;
public class TreeDTO {
private int id;
private String text;
private String iconCls;
private String checked;
private int parent_id;
private String state;
private Map attributes = new HashMap();
public TreeDTO() {
}
public TreeDTO(int id, String text, String iconCls, String checked,

public int getId() {

+ ", iconCls=" + iconCls + ", id=" + id + ", parent_id="
+ parent_id + ", state=" + state + ", text=" + text + "]";
}
}
4、创建接口DAO
MeunDao.java
package com.hsj.dao;
import java.util.List;
import com.hsj.domain.Menu;
import com.hsj.domain.TreeDTO;
public interface MenuDao{
public List getChildrenByParentId(String parentId);
public Menu findMenuById(int id);
public void save(T t);
public void update(Menu menu);
public void delete(int id);
public void deleteChildrenByParentId(int parentId);
public void deleteChildren(int id);
}
5、实现DAO接口方法Bean
MenuDaoBean.java
package com.hsj.dao.bean;
import java.lang.reflect.Field;
import java.lang.reflect.Method;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import com.hsj.dao.MenuDao;
import com.hsj.domain.Menu;
import com.hsj.domain.TreeDTO;
import com.hsj.utils.JDBCUtils;
public class MenuDaoBean implements MenuDao{
public int getTotalRecord(Class clazz) {
// TODO Auto-generated method stub
return 0;
}
public void save(T t)
{
//1.根据对象得到类模板对象
Class clazz= (Class) t.getClass();
//2.得到当前类中所有字段组成的数组，不管访问权限如何，但不包括父类中的字段
Field[] fields=clazz.getDeclaredFields();
//insert into t_menu(field1,field2,....) values(value1,value2,....)
List key=new ArrayList();//key用来存储字段列表
List
