    今天我打开我的SAP UI5应用,激活support assistant后,发现一条警告信息:ResponsiveLayout should not be used any longer because of UX requirements

    这条信息的提示字段resolution告诉了我正确做法:Use the ResponsiveGridLayout instead

    并给出参考链接:https://sapui5.hana.ondemand.com/#/api/sap.ui.layout.form.ResponsiveLayout

    The ResponsiveLayout renders a Form with a responsive layout. Internally the ResponsiveFlowLayout is used. The responsiveness of this layout tries to best use the available space. This means that the order of the FormContainers, labels and fields depends on the available space.

    ResponsiveLayout将form渲染成响应式布局,内部实现采用了ResponsiveFlowLayout,这种类型的布局将试图最大化地利用可用页面空间,意味着FormContainers,标签和字段的顺序依赖于可用空间。

    On the FormContainers, FormElements, labels and content fields, ResponsiveFlowLayoutData can be used to change the default rendering.

    We suggest using the ResponsiveGridLayout instead of this layout because this is easier to consume and brings more stable responsive output.

    现在SAP推荐使用ResponsiveGridLayout来替代ResponsiveLayout,因为前者能产生更稳定的响应式布局。

    而ResponsiveGridLayout内部使用的是Grid控件。

    这个错误是如何被检测出来的呢?

    代码如下:

    	check: function (oIssueManager, oCoreFacade, oScope) {
    				oScope.getElementsByClassName("sap.ui.layout.form.Form")
    					.forEach(function (oForm) {
    						var oLayout = oForm.getLayout();
    						if (oLayout && oLayout.isA("sap.ui.layout.form.ResponsiveLayout")) {
    							var oParent = oForm.getParent();
    							var sId;
    							var sName = "Form";
    	
    							if (isSimpleForm(oParent)) {
    								sId = oParent.getId();
    								sName = "SimpleForm";
    							} else if (isSmartForm(oParent)) {
    								// for SmartForm don't check on Form level
    								return;
    							} else {
    								sId = oForm.getId();
    							}
    	
    							oIssueManager.addIssue({
    								severity: Severity.Medium,
    								details: sName + " " + sId + " uses ResponsiveLayout.",
    								context: {
    									id: sId
    								}
    							});
    						}
    					});
    			},
    

    首先用JavaScript原生DOM API oScope.getElementsByClassName(“sap.ui.layout.form.Form”)拿到所有类为sap.ui.layout.form.Form的标签,然后忽略SmartForm的检测,最后获得form的ID,打印到support Assistant上。

    maven中mirror和reposity的区别

     <!-- mirrors

    An Intent is something that is used right now; a PendingIntent is something that may create an Intent in the future. You will use a PendingIntent with Notifications, AlarmManager, etc.

    Notification n = new Notification(R.drawable.face_1, "Service启动", System.currentTimeMillis());  
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, TServiceHolder.class), 0);  
    n.setLatestEventInfo(this, "任务标题", "任务内容", contentIntent);  
    nManager.notify(NOTIFICATION_ID, n); // 任务栏启动  

     

    String msg ="你好,美女";  
    String number = "187****5477";  
    SmsManager sms = SmsManager.getDefault();  
      
    PendingIntent pi = PendingIntent.getBroadcast(SmsActivity.this,0,new Intent(...),0);  
    sms.sendTextMessage(number, null, msg, pi, null);  //短信发送成功后要把intent广播出去
    Toast.makeText(SmsActivity.this,"发送成功",Toast.LENGHT_LONG).show();  

     

    By giving a PendingIntent to another application, you are granting it the right to perform the operation you have specified as if the other application was yourself,就相当于PendingIntent代表了Intent

    函数SmsManager.sendTextMessage(String destinationAddress, String scAddress, String text, PendingIntent sentIntent, PendingIntent deliveryIntent)中参数解释:
          1)PendingIntent sentIntent:当短信发出时,成功的话sendIntent会把其内部的描述的intent广播出去,否则产生错误代码并通过android.app.PendingIntent.OnFinished进行回调,这个参数最好不为空,否则会存在资源浪费的潜在问题;
          2)PendingIntent deliveryIntent:是当消息已经传递给收信人后所进行的PendingIntent广播。
          查看PendingIntent 类可以看到许多的Send函数,就是PendingIntent在进行被赋予的相关的操作。

     

    ==============================================================================

    Intent 表示一个目的,第一个参数表示所在类,第二个参数表示目标类
    PendingIntent 即是一个Intent的描述
    PendingIntent和Intent的区别:
    PendingIntent就是一个Intent的描述,我们可以把这个描述交给别的程序,别的程序根据这个描述在后面的别的时间做你安排做的事情
    换种说法Intent 字面意思是意图,即我们的目的,我们想要做的事情,在activity中,我们可以立即执行它
    PendingIntent 相当于对intent执行了包装,我们不一定一定要马上执行它,我们将其包装后,传递给其他activity或application
    这时,获取到PendingIntent  的application 能够根据里面的intent 来得知发出者的意图,选择拦击或者继续传递或者执行

    过滤器和拦截器

    Difference:
    A Servlet Filter is used in the web layer only, you can’t use it outside of a
    web context. Interceptors can be used anywhere. That’s the main difference.

    In my opinion one of the biggest difference between Filters and Interceptors is:

    Filter works only in J2EE web applications, you can not use outside of the application servers, Interceptors can work in different components and not depends on the web layer, in summary interceptor have a wide field than filters. If you are planning to move some component outside the container, you should consider use interceptors.

    Filters work more in the request/response domain, in the other hand interceptor act more in the method execution domain.

    If you need to do something that could affect the request or response to your application such as logging, security, audit, or you will affect the data coming on them, your option is filter, don’t forget the plug ability that those provides.

    Interceptors are used in conjunction with Java EE managed classes to allow developers to invoke interceptor methods on an associated target class, in conjunction with method invocations or lifecycle events.

    • Filter基于回调函数,我们需要实现的filter接口中doFilter方法就是回调函数,而interceptor则基于java本身的反射机制,这是两者最本质的区别。
    • Filter是依赖于servlet容器的,即只能在servlet容器中执行,很显然没有servlet容器就无法来回调doFilter方法。而interceptor与servlet容器无关。
    • Filter的过滤范围比Interceptor大,Filter除了过滤请求外通过通配符可以保护页面,图片,文件等等,而Interceptor只能过滤请求。
    • Filter的过滤例外一般是在加载的时候在init方法声明,而Interceptor可以通过在xml声明是guest请求还是user请求来辨别是否过滤

    ####综上所述
    一个简单的数据流程,请求过来进入到 Filter pre —>dispatcher—>preHandle–>controller–>postHandle—>afterCompletion—>Filter After
