参考 Organization

Result.jsp

1.增加左侧的tree栏目

<div data-options="region:'west',split:true,border:false" style="width: 250px;">
	<div class="TREE_COMMON_BOX_SPLIT_DIV">
			<a id="examTypeTreeReload" href="javascript:void(0)"
				class="easyui-linkbutton" data-options="plain:true"
				iconCls="icon-reload">刷新</a> 
            <a id="examTypeTreeOpenAll" href="javascript:void(0)" 
                class="easyui-linkbutton" data-options="plain:true" 
                iconCls="icon-sitemap">展开</a>
	</div>
	<ul id="examTypeTree"></ul>
</div>
<div class="easyui-layout" data-options="region:'center',border:false">

</div>

2.添加和树相关的javascript

$('#examTypeTree').tree({
	url : 'examtype/examtypeTree.do',
	onSelect : function(node) {
		$('#PARENTID_RULE').val(node.id);
		$('#PARENTTITLE_RULE').val(node.text);
		searchTypeTree.dosearch({
			'ruleText' : searchTypeTree.arrayStr()
		});
	}
});
$('#examTypeTreeReload').bind('click', function() {
	$('#examTypeTree').tree('reload');
});
$('#examTypeTreeOpenAll').bind('click', function() {
	$('#examTypeTree').tree('expandAll');
});

3.增加查询条件中分类缓存表单

<tr>
	<td class="title">上级节点:</td>
	<td>
        <input id="PARENTTITLE_RULE" type="text"
		readonly="readonly" style="background: #F3F3E8"> 
        <input id="PARENTID_RULE" name="PARENTID:=" type="hidden">
    </td>
</tr>

4.在新增方法中添加parentid的参数

//新增
function addDataExamtype() {
	var parentID = $("#PARENTID_RULE").val();
	var url = url_formActionExamtype + '?operateType=' + PAGETYPE.ADD
                  +'&parentId='+parentID;
	$.farm.openWindow({
		id : 'winExamtype',
		width : 600,
		height : 300,
		modal : true,
		url : url,
		title : '新增'
	});
}

<tr>
	<td class="title">上級分类:</td>
	<td><c:if test="${empty parent}">无</c:if>${parent.name}<input
		type="hidden" name="parentid" value="${parent.id}"></td>
	<td class="title"></td>
	<td></td>
</tr>

<td class="title">排序:</td>
<td colspan="3">
		<input type="text" style="width: 120px;" class="easyui-validatebox" data-options="required:true,validType:['integer','maxLength[5]']" id="entity_sort" name="sort" value="${entity.sort}">
</td>

submitFormOrganization.postSubmit(submitEditActionOrganization,function() {
         $.messager.confirm('确认对话框', '数据更新,是否重新加载左侧组织机构树？',function(r) {
         if (r) {
		$('#OrganizationTree').tree('reload');
		}
			});
		return true;
});

在Controller中

if (query.getQueryRule().size() == 0) {
    query.addRule(new DBRule("PARENTID", "NONE", "="));
}

1.增加tree的查询方法

/**
* 组织机构节点
*/
@RequestMapping("/examtypeTree")
@ResponseBody
public Object examtypeTree(String id) {
	try {
		if (id == null) {
			// 如果是未传入id，就是根节点，就构造一个虚拟的上级节点
			id = "NONE";
			List<EasyUiTreeNode> list = new ArrayList<>();
			EasyUiTreeNode nodes = new EasyUiTreeNode("NONE", "考试分类", "open"
                                , "icon-customers");
			nodes.setChildren(EasyUiTreeNode.formatAsyncAjaxTree(
				EasyUiTreeNode.queryTreeNodeOne(id, "SORT", "WTS_EXAM_TYPE", 
                                     "ID", "PARENTID", "NAME", "CTIME").getResultList(),
				EasyUiTreeNode.queryTreeNodeTow(id, "SORT", "WTS_EXAM_TYPE",
                                    "ID", "PARENTID", "NAME", "CTIME")
				     .getResultList(),"PARENTID", "ID", "NAME", "CTIME"));
			list.add(nodes);
			return list;
		}
		return EasyUiTreeNode.formatAsyncAjaxTree(
			EasyUiTreeNode.queryTreeNodeOne(id, "SORT", "WTS_EXAM_TYPE", 
                  "ID", "PARENTID", "NAME", "CTIME").getResultList(),
			EasyUiTreeNode.queryTreeNodeTow(id, "SORT", "WTS_EXAM_TYPE", 
                              "ID", "PARENTID", "NAME", "CTIME").getResultList(),
				"PARENTID", "ID", "NAME", "CTIME");
	} catch (Exception e) {
		log.error(e.getMessage());
		return ViewMode.getInstance().setError(e.getMessage(), e).returnObjMode();
	}
}

2.修改view方法，增加parent参数的返回

/**
* 显示详细信息（修改或浏览时）
*
 * @return
*/
@RequestMapping("/form")
public ModelAndView view(RequestMode pageset, String ids, String parentId) {
	try {
			Examtype parent = null;
			if (StringUtils.isNotBlank(parentId)) {
                parent = projectTypeServiceImpl.getProjecttypeEntity(parentId);
               }
			switch (pageset.getOperateType()) {
			case (1): {// 新增
				return ViewMode.getInstance().putAttr("pageset", pageset)
                                        .putAttr("parent", parent)
					.returnModelAndView("exam/ExamtypeForm");
			}
			...
			return ViewMode.getInstance().returnModelAndView("exam/ExamtypeForm");
	} catch (Exception e) {
		...
	}
}

server

1新增方法处理parentid

if (StringUtils.isBlank(entity.getParentid())) {
	 entity.setParentid("NONE");
}
entity.setTreecode("NONE");
entity = projecttypeDaoImpl.insertEntity(entity);
initTreeCode(entity.getId());
return entity;

private void initTreeCode(String treeNodeId) {
	ProjectType node = getProjecttypeEntity(treeNodeId);
	if (node.getParentid().equals("NONE")) {
		node.setTreecode(node.getId());
	} else {
		node.setTreecode(projecttypeDaoImpl.getEntity(node.getParentid()).getTreecode() + node.getId());
	}
	projecttypeDaoImpl.editEntity(node);
}

@Override
@Transactional
public void deleteProjecttypeEntity(String id, LoginUser user) {
	if (projecttypeDaoImpl.selectEntitys(DBRule.addRule(new ArrayList<DBRule>(), "parentid", id, "=")).size() > 0) 
        {
		throw new RuntimeException("不能删除该节点，请先删除其子节点");
	 }
         projecttypeDaoImpl.deleteEntity(projecttypeDaoImpl.getEntity(id));
}
