在action中调用 this.render() 开始模版渲染流程。如果在模版中调用 {% render "index:child %} 会渲染子模版，并返回渲染后的HTML。注意{% render "index:child %}不仅仅只是将其渲染后的HTML包含进来，它会执行完整的 action !. 上面完成了view.html模版的渲染后，还不能直接返回给浏览器，他不是完整的HTML。下面还要渲染 Layout 布局模版，{{ view}} 会替换为上面的 view.html渲染后的内容，这样 view.html 和 layout.html拼接起来才是一个完整的HTML 页面。. 布局模版 顾名思义，即定义一个HTML的基本结构。如一个网站的头部、尾部每个页面基本相同，只是中间内容在发生变化，这些公用的部分就应该放在__布局模版__中，以减少重复代码，主模版就只是中间变化的这部分内容。 布局模版默认是开启的，如果你的主模版(如上面的view.html)已经包含完整的HTML，不想拼接布局模版，通过设置this.render 第二个参数 layout = null 来关闭布局模式。即 this.render(data, {layout: null})。.

QUESTION
I have a service that is responsible to execute a httpClient.get every x seconds, using a timer. I need this timer to start running whenever the service is up, so the timer is defined in the service constructor. According to my understanding, the subscription should be registered in the timer scope as seen below (I don't want to change it if there's no need, unless it is incorrect).
The all system is working fine as long as there are no errors\exceptions\error 500 exception from the backend server. Now, I need 2 things:
- I would like to catchError whenever there is a problem in the backend server.
- I would like the observer to keep running according to the timer times (to the next tick), even if there is an exception. My final result should be reaching the popUpAlert in the component whenever there is exception See my code - this the webapi controller:

CatchErroroperator allows to handle error, but doesn't change nature of observable - error is terminal condition to given observable so emission will stop.CatchErrorallows to emit desires value when it occurs instead of raising observer's error callback (metasong).
You might want to handle errors in inner Observable (i.e. inside switchMap), so errors raised there, will not bubble up to main stream, that way the main stream continues after an error occurs, as demonstrated below:

QUESTION
I have a bare metal cluster with 3 servers which are publicly available but each one has a totally different ip address. I have my DNS entry to point to all 3 hosts - so traffic can received by any host. I have all of them connected via a vlan. Now I would like that traffic coming from internet is forwarded to the k8s node, where the service is running:
...ANSWER
Answered 2019-Aug-21 at 14:38Your environment is not a good fit for MetalLB - you would need IPs that can be assigned to any node (floating IP / service IP). For your situation a reverse proxy, which is called Ingress in Kubernetes, would be a better solution.
QUESTION
I have a Servlet Filter within my Spring Boot (2.0.1) application that I'm registering with FilterRegistrationBean which I need it to be executed first (order of one) along the filter chain. The application is deployed to JBoss 7.2. This filter also has a dependency that is injected with @Autowired (see below):
ANSWER
Answered 2019-Aug-16 at 20:18If you create an object by yourself, using new, and this object is not returned by a @Bean-annotated method, then it's not a Spring bean, and Spring will thus not inject anything in it.
You can just add an @Bean-annotated method returning new MyFilter(), and call that method from myFilter() to get the bean, or add a MyFilter as argument to myFilter().
Example:
QUESTION
I have a Java Spring Boot application which has a Scheduler which calls a async task from a Service The task takes a few minutes (usually 3-5mins) to complete.
The same async method from the Service can also be called trough a UI Application, by calling the API from the Spring Boot Controller.
Code:
Scheduler
...ANSWER
Answered 2019-May-17 at 03:36In your particular case , you need to reset the database after application deployment, so the best way for you to do that is to use the Spring CommandLineRunner .
Spring boot provides a CommanLineRunner interface with a callback run() method which can be invoked at application startup after the Spring application context is instantiated.
CommandLineRunner beans can be defined within the same application context and can be ordered using the @Ordered interface or @Order annotation.

QUESTION
I have two machines. On both I have WAS 8.5.5.x ND. So I want create on Computer1 an app server and on Computer2 a cluster for this server.
I've created on Computer1 Development manager(Dmgr01), nodeagent(node - hostnameNode01, cell - hostnameCell01) and server (mysrv at the same cell and node). And it works fine. But how can I create an external node/custom profile with another host(Computer2 hostname) to create a cluster for hostnameCell01 on Computer2 using Dmgr01?
...ANSWER
Answered 2017-Feb-07 at 13:35Create a standalone application server on computer2, and follow these steps to federate it into the cell: https://www.ibm.com/support/knowledgecenter/en/SSAW57_8.5.5/com.ibm.websphere.nd.doc/ae/tagt_svr_conf_nodes.html They'll show you how to use the administrative console on the deployment manager to add the new node.
If you want to do it from computer2 instead, you can use the addNode command: https://www.ibm.com/support/knowledgecenter/en/SSAW57_8.5.5/com.ibm.websphere.nd.doc/ae/rxml_addnode.html If you go that route, make sure when you create the standalone application server profile that you give it a different cell name than the cell you actually intend it to be federated to. There's a list of best practices for addNode here: https://www.ibm.com/support/knowledgecenter/SSAW57_8.5.5/com.ibm.websphere.nd.doc/ae/rxml_nodetips.html

Answered 2017-Nov-28 at 15:24Turns out my problem was that I'm using SQL server 2005, and Scaffold-Dbcontext has errors with dbo.sysdiagrams on that version. Had to go back to an older version of .NET.
These weren't just warnings, because I wasn't able to scaffold my model before I resolved this.
