Spring Boot - infinite loop service

由 做~自己de王妃 提交于 2019-12-21 05:11:07
问题 I want to build a headless application which will query the DB in infinite loop and perform some operations in certain conditions (e.g. fetch records with specific values and when found launch e-mail sending procedure for each message). I want to use Spring Boot as a base (especially because of Actuator to allow expose health-checks), but for now I used Spring Boot for building REST web-services. Is there any best practices or patterns to follow when building infinite loop applications ? Does

问题 I'm writing some watir test cases: browser.goto "http://egauge2592.egaug.es/" browser.link(:href,"/settings.html").click browser.text_field(:index,4).set("some text") browser.button(:id,"save_button").click then a 'Authentication Required' dialogue opens, asking for username and password .

由 旧街凉风 提交于 2019-12-20 06:43:36
问题 The main difference is, execution on GUI bases and non GUI bases(Headless). I am looking for difference between all Headless browsers with each other, But unfortunately I didn't find any.

Serverless 实战——使用 Rendertron 搭建 Headless Chrome 渲染解决方案

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 为什么需要 Rendertron？ 传统的 Web 页面，通常是服务端渲染的，而随着 SPA（Single-Page Application） 尤其是 React、Vue、Angular 为代表的前端框架的流行，越来越多的 Web App 使用的是客户端渲染。 使用客户端渲染有着诸多优势，比如节省后端资源、局部刷新、前后端分离等等，但也带来了一些挑战，比如本文要解决的 SEO 问题。 对于服务端渲染的页面，服务端可以直接将内容通过 HTML 的形式返回，搜索引擎爬虫可以轻易的获取页面内容，而对于客户端渲染的应用，客户端必须执行服务器返回的 Javascript 才能得到正确的网页内容。目前，除 Google、Bing 支持 Javascript 外（也会有一些限制），其他的大部分搜索引擎都不支持 Javascript，也就无法获取正确的网页内容。 Google 推出的 Rendertron 就是为了解决这样场景的一款工具。通过使用 Rendertron，SPA 也能够被不支持执行 Javascript 的搜索引擎爬取渲染后的内容。其原理主要是通过使用 Headless Chrome 在内存中执行 Javascript，并在得到完整内容后，将内容返回给客户端。 Rendertron 原理介绍 通常会将

问题 While reading the QTKit Application Programming Guide I came across the term 'headless environments' - what does this mean? Here is the passage: ...including applications with a GUI and tools intended to run in a “headless” environment. For example, you can use the framework to write command-line tools that manipulate QuickTime movie files. 回答1: "Headless" in this context simply means without a graphical display. (i.e.: Console based.) Many servers are "headless" and are administered over SSH
