jeecg中树形显示的用法

1.GoodsController中显示的方法如下：

@RequestMapping(params = "goodsgrid")
@ResponseBody
public Object goodsgrid(GoodEntity good,HttpServletRequest request, HttpServletResponse response, TreeGrid treegrid) {
CriteriaQuery cq = new CriteriaQuery(GoodEntity.class);
if("yes".equals(request.getParameter("isSearch"))){
treegrid.setId(null);
good.setId(null);
}
if(null != good.getGoodsName()){
org.jeecgframework.core.extend.hqlsearch.HqlGenerateUtil.installHql(cq, good);
}
if (treegrid.getId() != null) {
int c = Integer.parseInt(treegrid.getId());
cq.eq("ggood.id", c);
}
if (treegrid.getId() == null) {
cq.isNull("ggood");
}
cq.add();
List<TreeGrid> goodsList=null;
goodsList =systemService.getListByCriteriaQuery(cq, false);

if(goodsList.size()==0&&good.getGoodsName()!=null){
cq = new CriteriaQuery(GoodEntity.class);
GoodEntity pargood = new GoodEntity();
good.setGgood(pargood);
org.jeecgframework.core.extend.hqlsearch.HqlGenerateUtil.installHql(cq, good);
goodsList =systemService.getListByCriteriaQuery(cq, false);
}
List<TreeGrid> treeGrids = new ArrayList<TreeGrid>();
TreeGridModel treeGridModel = new TreeGridModel();
treeGridModel.setTextField("goodsCode"); 
treeGridModel.setParentText("ggood_goodsName");
treeGridModel.setParentId("ggood_id");
treeGridModel.setSrc("goodsDetail");
treeGridModel.setIdField("id");
treeGridModel.setChildList("goods"); 
Map<String,Object> fieldMap = new HashMap<String, Object>();
fieldMap.put("goodsName", "goodsName");
fieldMap.put("addTime", "addTime");
treeGridModel.setFieldMap(fieldMap);
treeGrids = systemService.treegrid(goodsList, treeGridModel);

JSONArray jsonArray = new JSONArray();
for (TreeGrid treeGrid : treeGrids) {
jsonArray.add(JSON.parse(treeGrid.toJson()));
}
System.out.println(jsonArray);
return jsonArray;
}

父物料下显示子物料的方法

@RequestMapping(params = "setPFunction")
@ResponseBody
public List<ComboTree> setPFunction(HttpServletRequest request, ComboTree comboTree) {
CriteriaQuery cq = new CriteriaQuery(GoodEntity.class);
if(null != request.getParameter("selfId")){
cq.notEq("id", request.getParameter("selfId"));
}
if (comboTree.getId() != null) {
// String fname= jdbcTemplate.queryForObject("select goods_name from t_item where goods_id=?",String.class,comboTree.getId()) ;
cq.eq("ggood.id", comboTree.getId());
}
if (comboTree.getId() == null) {
cq.isNull("ggood");
}
cq.add();
List<GoodEntity> goodsList = systemService.getListByCriteriaQuery(cq, false);
List<ComboTree> comboTrees = new ArrayList<ComboTree>();
ComboTreeModel comboTreeModel = new ComboTreeModel("id", "goodsName", "goods");
comboTrees = systemService.ComboTree(goodsList, comboTreeModel, null, true);
return comboTrees;

}

2.该商品对应的实体类的方法GoodEntity：

@Entity
@Table(name = "wsc_goods", schema = "")
@DynamicUpdate(true)
@DynamicInsert(true)
@SuppressWarnings("serial")
public class GoodEntity implements java.io.Serializable {

/**上级类目*/
private GoodEntity ggood;
/**下级类目*/
private List<GoodEntity> goods = new ArrayList<GoodEntity>();
/**商品代码*/
private java.lang.Integer id;
/**商品名称*/
private java.lang.String goodsName;
/**商品图片*/
private java.lang.String goodsImg;
/**goodsSpe*/
private java.lang.String goodsSpe;
/**商品单价*/
private java.math.BigDecimal goodsPrice;
/**商品详情*/
private java.lang.String goodsDetail;
/**goodsNum*/
private java.lang.Integer goodsNum;
/**添加时间*/

/**物料代码*/

/**单位*/
private java.lang.String goodsUnit;

this.addTime = addTime;
}

@Column(name ="GOODS_NUM",nullable=true,length=255)
public java.lang.Integer getGoodsNum(){
return this.goodsNum;
}

/**

*@param: java.lang.String goodsNum
*/
public void setGoodsNum(java.lang.Integer goodsNum){
this.goodsNum = goodsNum;
}

/**

*@return: java.lang.Integer 订单状态
*/
@Column(name ="STATUS",nullable=true)
public java.lang.Integer getStatus(){
return this.status;
}

/**

*/
public void setStatus(java.lang.Integer status){
this.status = status;
}

@Column(name ="goods_detail",nullable=true)
public java.lang.String getGoodsDetail() {
return goodsDetail;
}

public void setGoodsDetail(java.lang.String goodsDetail) {
this.goodsDetail = goodsDetail;
}

@Column(name ="ctg_id",nullable=true)
public java.lang.Integer getCtgId() {
return ctgId;

public java.lang.String getGoodsUnit() {
return goodsUnit;
}

public void setGoodsUnit(java.lang.String goodsUnit) {

}

}

要注意的是id和parentid的1对多的关系。

3.前端jsp页面的显示页面  goodsList.jsp

url : 'goodsController.do?setPFunction&selfId=${good.id}',
width: 155,
onSelect : function(node) {
// alert(node.text);
// changeOrgType();
}
});
})
/* function changeOrgType() { // 处理组织类型，不显示公司选择项
var orgTypeSelect = $("#orgType");
var optionNum = orgTypeSelect.get(0).options.length;
if(optionNum == 1) {
$("#orgType option:first").remove();
var bumen = '<option value="2" <c:if test="${orgType=='2'}">selected="selected"</c:if>><t:mutiLang langKey="common.goodment"/></option>';
var gangwei = '<option value="3" <c:if test="${orgType=='3'}">selected="selected"</c:if>><t:mutiLang langKey="common.position"/></option>';
