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];

d.id = "jn";

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>
