思维导图

自定义mvc02

 先给界面中添加Tabs选项卡

$(function() {
	$("#bookMenus").tree({
		url:$("#ctx").val()+"/permission.action?methodName=tree",
		onClick: function(node){
			var exists=$("#bookTabs").tabs('exists',node.text);
			if(exists){
				$("#bookTabs").tabs('select',node.text);
			}else{
				$('#bookTabs').tabs('add',{    
				    title:node.text,    
				    content:'<iframe width="100%" height="100%" src="'+$("#ctx").val()+node.attributes.self.url+'"/>',    
				    closable:true
				});  

			}
		}
	});
})

一.书籍类别下拉框

①实体类，dao包以及web包

package com.lsy.entity;

public class Category {
	private long id;
	private String name;
	public long getId() {
		return id;
	}
	public void setId(long id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	@Override
	public String toString() {
		return "Category [id=" + id + ", name=" + name + "]";
	}
	
}

dao包（查出所有类别）

package com.lsy.dao;

import java.util.List;

import com.lsy.entity.Category;
import com.zking.util.BaseDao;
import com.zking.util.PageBean;

public class CategoryDao extends BaseDao<Category>{
	
	public List<Category> list(Category category, PageBean pageBean) throws Exception {
		String sql="select * from t_easyui_category";
		return super.executeQuery(sql, Category.class, pageBean);
	}
}

web包

package com.lsy.web;

import java.util.List;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.lsy.dao.CategoryDao;
import com.lsy.entity.Category;
import com.zking.framework.ActionSupport;
import com.zking.framework.ModelDriver;
import com.zking.util.ResponseUtil;

public class CategoryAction extends ActionSupport implements ModelDriver<Category>{
	private Category category=new Category();
	private CategoryDao categoryDao=new CategoryDao();
	
	@Override
	public Category getModel() {
		return category;
	}
	
	/**
	 * 书籍类别下拉框
	 * @param req
	 * @param resp
	 * @return
	 */
	public String combobox(HttpServletRequest req, HttpServletResponse resp) {
		try {
			List<Category> list = categoryDao.list(category, null);
			ResponseUtil.writeJson(resp, list);
		} catch (Exception e) {
			e.printStackTrace();
		}
		return null;
	}
	
}

配置xml文件

<action path=”/category” type=”com.lsy.web.CategoryAction”>
    </action>

addBook.jsp界面代码

 $(function () {
        $(‘#cid’).combobox({

 二.新增书籍与修改书籍

书籍实体类，dao包，web包

①实体类

设置时间格式（这是东八区的时间段，北京时间）

@JsonFormat(pattern=”yyyy-MM-dd HH:mm:ss”,timezone = “GMT+8”)

package com.lsy.entity;

import java.util.Date;

import com.fasterxml.jackson.annotation.JsonFormat;

public class Book {
	private long id;
	private String name;
	private String pinyin;
	private long cid;
	private String author;
	private float price;
	private String image;
	private String publishing;
	private String description;
	private int state;
	@JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone = "GMT+8")
	private Date deployTime;
	private int sales;
	public long getId() {
		return id;
	}
	public void setId(long id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getPinyin() {
		return pinyin;
	}
	public void setPinyin(String pinyin) {
		this.pinyin = pinyin;
	}
	public long getCid() {
		return cid;
	}
	public void setCid(long cid) {
		this.cid = cid;
	}
	public String getAuthor() {
		return author;
	}
	public void setAuthor(String author) {
		this.author = author;
	}
	public float getPrice() {
		return price;
	}
	public void setPrice(float price) {
		this.price = price;
	}
	public String getImage() {
		return image;
	}
	public void setImage(String image) {
		this.image = image;
	}
	public String getPublishing() {
		return publishing;
	}
	public void setPublishing(String publishing) {
		this.publishing = publishing;
	}
	public String getDescription() {
		return description;
	}
	public void setDescription(String description) {
		this.description = description;
	}
	public int getState() {
		return state;
	}
	public void setState(int state) {
		this.state = state;
	}
	public Date getDeployTime() {
		return deployTime;
	}
	public void setDeployTime(Date deployTime) {
		this.deployTime = deployTime;
	}
	public int getSales() {
		return sales;
	}
	public void setSales(int sales) {
		this.sales = sales;
	}
	@Override
	public String toString() {
		return "Book [id=" + id + ", name=" + name + ", pinyin=" + pinyin + ", cid=" + cid + ", author=" + author
				+ ", price=" + price + ", image=" + image + ", publishing=" + publishing + ", description="
				+ description + ", state=" + state + ", deployTime=" + deployTime + ", sales=" + sales + "]";
	}
	
}

②dao包

package com.lsy.dao;

import java.util.Date;
import java.util.List;

import com.lsy.entity.Book;
import com.zking.util.BaseDao;
import com.zking.util.PageBean;
import com.zking.util.PinYinUtil;
import com.zking.util.StringUtils;

public class BookDao extends BaseDao<Book>{
	public List<Book> list(Book book, PageBean pageBean) throws Exception {
		String sql="select * from t_easyui_book where 1=1";
		String name=book.getName();
		int state=book.getState();
		if(StringUtils.isNotBlank(name)) {
			sql+= " and name like'%"+name+"%'";
		}
		if(state!=0) {
			sql+=" and state="+state;
		}
		return super.executeQuery(sql, Book.class, pageBean);
	}
	
	public void edit(Book t) throws Exception {
		super.executeUpdate("update t_easyui_book set name=?,pinyin=?,cid=?,image=?,state=?,sales=? where id=?", 
				t, new String[] {"name","pinyin","cid","image","state","sales","id"});
	}
	
	public void add(Book t) throws Exception {
		t.setPinyin(PinYinUtil.getAllPingYin(t.getName()));
		t.setDeployTime(new Date());
		String sql="insert into t_easyui_book(name,pinyin,cid,author,price,image,publishing,description,state,deployTime,sales) values(?,?,?,?,?,?,?,?,?,?,?)";
		super.executeUpdate(sql,
				t, new String[] {"name","pinyin","cid","author","price","image","publishing","description","state","deployTime","sales"});
	}

	public void editStatus(Book t) throws Exception{
		super.executeUpdate("update t_easyui_book set state=? where id=?", 
				t, new String[] {"state","id"});
		
	}
}

③web包

package com.lsy.web;

import java.util.List;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.lsy.dao.BookDao;
import com.lsy.entity.Book;
import com.zking.framework.ActionSupport;
import com.zking.framework.ModelDriver;
import com.zking.util.PageBean;
import com.zking.util.R;
import com.zking.util.ResponseUtil;

public class BookAction extends ActionSupport implements ModelDriver<Book>{
	private Book book=new Book();
	private BookDao bookDao=new BookDao();
	
	@Override
	public Book getModel() {
		return book;
	}
	
	public void list(HttpServletRequest req, HttpServletResponse resp) {
		PageBean pageBean=new PageBean();
		pageBean.setRequest(req);
		try {
			List<Book> list = bookDao.list(book, pageBean);
			ResponseUtil.writeJson(resp, new R()
					.data("total", pageBean.getTotal())
					.data("rows", list));
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
	
	public void add(HttpServletRequest req, HttpServletResponse resp) {
		try {
			bookDao.add(book);
			ResponseUtil.writeJson(resp,1);
		} catch (Exception e) {
			e.printStackTrace();
			try {
				ResponseUtil.writeJson(resp,0);
			} catch (Exception e1) {
				e1.printStackTrace();
			}
		}
	}
	
	/**
	 * 如果上架，书籍的状态改为2
	 * 如果下架，状态改为3
	 * @param req
	 * @param resp
	 */
	public void edit(HttpServletRequest req, HttpServletResponse resp) {
		try {
			bookDao.edit(book);
			ResponseUtil.writeJson(resp,1);
		} catch (Exception e) {
			e.printStackTrace();
			try {
				ResponseUtil.writeJson(resp,0);
			} catch (Exception e1) {
				e1.printStackTrace();
			}
		}
	}
	
	public void editStatus(HttpServletRequest req, HttpServletResponse resp) {
		try {
			bookDao.editStatus(book);
			ResponseUtil.writeJson(resp,1);
		} catch (Exception e) {
			e.printStackTrace();
			try {
				ResponseUtil.writeJson(resp,0);
			} catch (Exception e1) {
				e1.printStackTrace();
			}
		}
		
		
	}
	
	
}

配置xml文件

<action path=”/book” type=”com.lsy.web.BookAction”>
    </action>

addBook.jsp界面书写增加点击事件

function submitForm() {
        $(‘#ff’).form(‘submit’, {    
            url:’${pageContext.request.contextPath}/book.action?methodName=add’,    
            success:function(data){    
                if(data==1){
                    $(‘#ff’).form(‘clear’);            
                }
            }    
        });

 三.书籍的上架与下架功能

BookDao的editStatus方法

public void editStatus(Book t) throws Exception{
        super.executeUpdate(“update t_easyui_book set state=? where id=?”, 
                t, new String[] {“state”,”id”});
        
    }

listBook1.jsp界面中写点击事件

调用editStatus方法

function shangjia() {
        $.messager.confirm(‘确认’,’您确认想要上架此书籍吗？’,function(r){
            if (r){
                var row = $(‘#dg’).datagrid(‘getSelected’);
                if (row){
                    $.ajax({
                        url:’${pageContext.request.contextPath}/book.action?methodName=editStatus&state=2&id=’ + row.id,
                        success:function (data) {
                            
                        }
                    })
                } 
            }
        });

    }
