Question

我在集成spring和extjs时遇到错误。它只是登录页面的简单代码。

错误详情如下

无法加载资源：服务器响应状态为500 （内部服务器错误）ext-all.js：21未捕获的TypeError：无法读取属性'isProvider'未定义

带警告

找不到带URI的HTTP请求的映射 DispatcherServlet中的[/LoginExt_Spring_20-06/services/api.js] 名称'服务'

//This is my controller code

Ext.define('myapp.controller.LoginController',{
		extend:'Ext.app.Controller',
		stores:['LoginStore'],
		Views:['LoginView','HomeView'],
		refs:[
		      { ref:'loginview'},
		      {ref:'homepage'}
		      ],
		 init:function(){
			 this.control({
				 'loginview button[action=login]':{
					 click:'onLogin'
				 },
				 'loginview button[action=cancel]':{
					 click:'onCancel'
				 }
			 });
		 },
		onLogin:function(button){
			var loginForm=button.up('form[name=loginview]');
			var loginValues=loginForm.getValues();
			var login=loginForm.up('container[name=viewport]');
			var home=login.down('grid[name=homepage]');
			//console.log('loginValues are: '+loginValues.username);
			formController.authenticate(loginValues);
			//if(loginValues.username=='admin'&&loginValues.password=='password'){
				Ext.Msg.alert('status','successfull login');
				loginForm.setVisible(false);
				home.setVisible(true);
			//}else Ext.Msg.alert('status','Invalid credentials...');
		},
		
		onCancel:function(){
			var loginForm=button.up('form[name=loginview]');
			this.loginForm.getForm().reset();
		}
	});


//code in Store

Ext.define('myapp.store.LoginStore',{

		autoLoad:true,
		proxy:{

// I included 

Ext.require('Ext.direct.*', function() {
	Ext.direct.Manager.addProvider(Ext.app.REMOTING_API);
