自定mvc之新增，下架以及上架
2021/9/24 23:13:31
本文主要是介绍自定mvc之新增，下架以及上架，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
一.书籍类别下拉框
1.下拉框的实体类
package com.zking.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 + "]";
}
}
2.dao方法
package com.zking.dao;
import java.util.Date;
import java.util.List;
import com.zking.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> {
/**
* 查询
* @param book
* @param pageBean
* @return
* @throws Exception
*/
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);
}
/**
* 修改
* @param book
* @param attrs
* @throws Exception
*/
public void edit( Book book) throws Exception {
String sql="update t_easyui_book set name=?,pinyin=?,cid=?,image=?,state=?,sales=? where id=?";
super.executeUpdate(sql, book, new String[] {"name","pinyin","cid","image","state","sales","id"});
}
/**
* 增加
* @param book
* @param attrs
* @throws Exception
*/
public void add( Book book) throws Exception {
String sql="insert into t_easyui_book(name,pinyin,cid,author,price,image,publishing,description,state,deployTime,sales) values(?,?,?,?,?,?,?,?,?,?,?)";
//增加拼音
book.setPinyin(PinYinUtil.getAllPingYin(book.getName()));
//增加时间
book.setDeployTime(new Date());
super.executeUpdate(sql, book, new String[] {"name","pinyin","cid","author","price","image","publishing","description","state","deployTime","sales"});
}
//上架
public void editStatus(Book book) throws Exception {
String sql="update t_easyui_book set state=? where id=?";
super.executeUpdate(sql, book, new String[] {"state","id"});
}
}
3.CategoryAction
package com.zking.web;
import com.zking.dao.CategoryDao;
import com.zking.entity.Category;
import com.zking.framework.ActionSupport;
import com.zking.framework.ModelDriver;
import com.zking.util.ResponseUtil;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.List;
public class CategoryAction extends ActionSupport implements ModelDriver<Category> {
private Category category = new Category();
private CategoryDao categoryDao = new CategoryDao();
/**
* 加载书籍类别下拉框
* @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;
}
@Override
public Category getModel() {
return category;
}
}
4.配置mvc.xml文件
<action type="com.zking.web.CategoryAction" path="/Category"> </action>
5.新增下拉框組
$(function () {
$('#cid').combobox({
url:'${pageContext.request.contextPath}/category.action?methodName=combobox',
valueField:'id',
textField:'name'
});
});
6.运行效果
二、新增书籍
1.增加书籍的jsp界面

</div>
</div>
<script>
$(function () {
$('#cid').combobox({
url:'${pageContext.request.contextPath}/Category.action?methodName=combobox',
valueField:'id',
textField:'name'
});
});
function submitForm() {
$('#ff').form('submit',{
success:function(data){
if(data=1){
$('#ff').form('clear');
}
}
});
}
function clearForm() {
$('#ff').form('clear');
}
</script>
</body>
</html>
2.书籍的实体类
package com.zking.entity;
import java.util.Date;
import com.fasterxml.jackson.annotation.JsonFormat;
public class Book {
// id bigint
// name varchar 书籍名称
// pinyin varchar 拼音
// cid bigint 书籍类别

public String getPinyin() {
return pinyin;

+ ", price=" + price + ", image=" + image + ", publishing=" + publishing + ", description="
+ description + ", state=" + state + ", deployTime=" + deployTime + ", sales=" + sales + "]";
}
}
3.dao方法
package com.zking.dao;
import java.util.Date;
import java.util.List;
import com.zking.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> {
/**
* 查询
* @param book
* @param pageBean
* @return
* @throws Exception
*/
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);
}
/**

* @throws Exception
*/
public void edit( Book book) throws Exception {
String sql="update t_easyui_book set name=?,pinyin=?,cid=?,image=?,state=?,sales=? where id=?";
super.executeUpdate(sql, book, new String[] {"name","pinyin","cid","image","state","sales","id"});

}
//上架
public void editStatus(Book book) throws Exception {
String sql="update t_easyui_book set state=? where id=?";
super.executeUpdate(sql, book, new String[] {"state","id"});
}
}
3.BookAction（调用add方法）
package com.zking.web;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.zking.dao.BookDao;
import com.zking.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();
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 e2) {
e.printStackTrace();
}
}
}
/**
* 如果上架，书籍的状态改为2
* 如果下架，书籍的状态改为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 e2) {
e.printStackTrace();
}
}
}
//上架
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();
}
}
}
}
4.mvc.xml配置
<action type="com.zking.web.BookAction" path="/book"> </action>
5.新增界面（addBook.jsp）
function submitForm() {
$('#ff').form('submit',{
url:'${pageContext.request.contextPath}/book.action?methodName=add',
success:function(data){
if(data=1){
$('#ff').form('clear');
}
}
});
}
6.运行效果:
三.书籍上架
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) {
}
})
}
}
});
}
