编写测试类

import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;

@Path("/echo")
public class Echo {
	@GET
	@Path("/getDistrict")
	//@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
	//@Produces("application/json")
	public District[] getDistrict(){
		District[] arrD = new District[7];
		District d = new District();
		
		d.id = "jn";
		d.name = "济南";
		arrD[0] = d;
		d = new District();

dojo页面

第一种加载方式，编程：

require([
	"dojo/store/JsonRest",
	"dijit/Tree",
	"dijit/tree/ObjectStoreModel",
	"dojo/domReady!",
	"dijit/form/Select",
     "dijit/form/FilteringSelect",
	"dojox/data/JsonRestStore",
	"dojo/data/ObjectStore"
], function(){
	var objectStore  = new dojo.store.JsonRest({
		target: "/dojo/rest/echo/getDistrict"
	});
	var dataStore = new dojo.data.ObjectStore({objectStore: objectStore});
	var dt = new dijit.form.Select({  
		 store: dataStore,
		 labelAttr:'name'
        },  
        "dtSelect");  
	dt.startup();
});

<div id = "dtSelect"></div>

第二种加载方式，声明：

<div data-dojo-type="dojo/store/JsonRest" data-dojo-id="restData" data-dojo-props='target: "/dojo/rest/echo/getDistrict"'></div>
<div data-dojo-type="dojo/data/ObjectStore" data-dojo-id="restStore" data-dojo-props="objectStore: restData"></div>
<div data-dojo-id="corpSelect" data-dojo-type="dijit/form/Select" data-dojo-props='store: restStore, labelAttr:"name"'></div>
