Spring mvc jquery esayui tree使用概要

最近、tree表示エリア機能を作成し、jquery esayui Treeを使用して、後で自分で参考にします.
jsは変数タイプalert(typeof(a))を表示します.

spring Controller

	//       
	@RequestMapping(value = "getRegion",method=RequestMethod.POST)
	public @ResponseBody List<Region> getRegion(
			@RequestParam(value = "id", required = false) String id,
			Model model) {
		List<Region> regions=null;
		//    id  esayui tree            
		//         esayui tree        null   ,        
		if("".equals(id)||id==null){
			regions=permissionService.getRegions(null);
		}else{
			regions=permissionService.getRegions(id);
		}	
		for (Region r : regions) {
			//         
			//entity  state   @Transient，                   tree  
			if(r.getChildren().size()>0)
				
				r.setState("closed");
			else
				r.setState("open");
			r.setChildren(null);
		}
		return regions;

Entityエンティティクラス、主にgetParent()およびgetChildren()の@JsonIgnore寸法とgetState()の@Transient寸法に注目
