旅游管理系统：产品分类信息树状显示

产品分类信息树状形式显示

1.构建产品分类实体ProducType

package cn.tedu.ttms.product.entity;
import java.io.Serializable;
import java.util.Date;
public class ProductType implements Serializable{
private static final long serialVersionUID = 1L;
private Integer id;
private String name;
/**排序号*/
private Integer sort;
/**分类的父类id*/
private Integer parentId;
private String note;
private Date createdTime;
private Date modifiedTime;
private String createdUser;
private String modifiedUser;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getSort() {
return sort;
}
public void setSort(Integer sort) {
this.sort = sort;
}
public Integer getParentId() {
return parentId;
}
public void setParentId(Integer parentId) {
this.parentId = parentId;
}
public String getNote() {
return note;
}
public void setNote(String note) {
this.note = note;
}
public Date getCreatedTime() {
return createdTime;
}
public void setCreatedTime(Date createdTime) {
this.createdTime = createdTime;
}
public Date getModifiedTime() {
return modifiedTime;
}
public void setModifiedTime(Date modifiedTime) {
this.modifiedTime = modifiedTime;
}
public String getCreatedUser() {
return createdUser;
}
public void setCreatedUser(String createdUser) {
this.createdUser = createdUser;
}
public String getModifiedUser() {
return modifiedUser;
}
public void setModifiedUser(String modifiedUser) {
this.modifiedUser = modifiedUser;
}
@Override
public String toString() {
return "ProductType [id=" + id + ", name=" + name + ", sort=" + sort + ", parentId=" + parentId + ", note="
+ note + ", createdTime=" + createdTime + ", modifiedTime=" + modifiedTime + ", createdUser="
+ createdUser + ", modifiedUser=" + modifiedUser + "]";
}

}

2.构建产品分类数据访问层对象ProductTypeDao

public interface ProductTypeDao {
List<Map<String,Object>>
findObjects();
}

<mapper namespace="cn.tedu.ttms.product.dao.ProductTypeDao">
<!-- 查询所有分类及这个分类的父类名称 -->

<select id="findObjects"
resultType="map">
<!-- 方案1 -->
select c.*,p.name parentName
from tms_classes c left join tms_classes p
on c.parentId=p.id
<!--  方案2
select c.*,
(select name parentName
from tms_classes p
where c.parentId=p.id)
from tms_classes c
-->
</select>

</mapper>

3.service实现类

@Service
public class ProductTypeServiceImpl implements ProductTypeService {
@Autowired
private ProductTypeDao productTypeDao;
@Override
public List<Map<String, Object>> findObjects() {
return productTypeDao.findObjects();
}
}

4.构建产品分类控制层对象ProductController

@Controller
@RequestMapping("/type/")
public class ProductTypeController {
@Autowired
private ProductTypeService productTypeService;
@RequestMapping("listUI")
public String listUI(){
return "product/type_list";
}
@RequestMapping("doFindObjects")
@ResponseBody
public JsonResult doFindObjects(){
return new JsonResult(
productTypeService.findObjects());
}
}

5.构建产品分类type_list.js的实现

$(function(){
$("#queryFormId")
.on("click",".btn-search",doQueryObjects);
doGetObjects();
});
function doQueryObjects(){
//1.初始化当前页码
$("#pageId").data("pageCurrent",1);
//2.执行查询操作
doGetObjects();
}
function doGetObjects(){
//初始化url
var url="team/doFindPageObjects.do?t="+Math.random();
//初始化参数对象
var params={name:$("#searchNameId").val()};//object
var pageCurrent=$("#pageId").data("pageCurrent");
if(!pageCurrent)pageCurrent=1;
//params.pageCurrent=pageCurrent;
params['pageCurrent']=pageCurrent;//{page-Current:1}
//发送异步启动获取分页数据
$.post(url,params,function(result){//JsonResult
if(result.state==1){
//1.tbodyId对应位置显示team信息
setTableBodyRows(result.data.list)
//2.设置分页信息
setPagination(result.data.pageObject);
}else{
alert(result.message);
}
});
}
function setTableBodyRows(list){
//1.获得tbodyId对应的对象
var tBody=$("#tbodyId");
tBody.empty();
//2.迭代list集合(多个team记录信息)
for(var i in list){
//2.1 创建 tr 对象
var tr=$("<tr></tr>");
tr.data("id",list[i].id);//可选(看业务)
//2.2 创建tds串
var tds="<td><input type='checkbox' name='checkdId' value='"+list[i].id+"'></td>"+
"<td>"+list[i].name+"</td>"+
"<td>"+list[i].projectName+"</td>"+
"<td>"+(list[i].valid?'启用':'禁用')+"</td>"+
"<td><input type='button' class='btn btn-default btn-update' value='修改'></td>";
//2.3将td追加到tr对象
tr.append(tds);
//2.4将tr追加到tBody中
tBody.append(tr);
}
}
