问题 I want to run a maven project lifecycle starting, and ending, with the unit tests. How can I skip recompilation and re-resolution of dependencies and only run the test phase? 回答1: If you start maven by calling a phase it will execute all lifecycle phases up to the one you are calling. For example, when calling mvn test all the phases before the test lifecycle phase will be execute too: the project will be validated, sources and resources will be generated and processed, sources will be

react lifecycle methods understanding

问题 I am a newbie to React.js and I am trying hard to understand several methods in the React lifecycle methods. So far, I have something that confuses me: 1) As far as I understand, the difference between componentWillUpdate and componentWillReceiveProps is that componentWillReceiveProps will be called when the parent changes the props and we can use setState (setState of this child inside componentWillReceiveProps ). for example: react-table-sorter-demo var App = React.createClass({

Simplest Android Activity Lifecycle

问题 I noticed that the Android Developers Activity section has been updated since I started my app, but I am still unclear what the simplest Activity Lifecycle is. As far as I can make out: onCreate, onResume and onPause are the essential ones. The activity may be deleted any time after onPause, so I should save my whole app state to a file onPause and not rely on onStop or onDestroy. Also, onSaveInstanceState is not called before every onPause so is not really worth using. Rather than trying to

If you start maven by calling a phase it will execute all lifecycle phases up to the one you are calling. For example, when calling mvn test all the phases before the test lifecycle phase will be execute too: the project will be validated, sources and resources will be generated and processed, sources will be compiled, the same will happen to test sources and resources and finally unit tests will be run. But you can also

问题 Using React and Redux, imagine you have a component method that sends a request to an external API. import React, { Component } from 'react'; import { connect } from 'react-redux'; class MyComp extends Component { boolUpdate (val) { fetch('http://myapi.com/bool', { val }); } shouldComponentUpdate (nextProps) { return false; } render () { return <h1>Hello</h1>; } } const mapStateToProps = ({ bool }) => ({ bool }); export default connect(mapStateToProps)(MyComp); Now let's say that you want to

How can I map Maven lifecycle phases not covered by the Eclipse m2e plugin?

问题 I’m using Eclipse Kepler on Mac 10.9.5. I have imported a number of Maven projects using the m2e Eclipse plugin. All these projects are children of a parent pom. When I look at the “Overview” in the individual child pom.xml files, I see stuff like this: Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:properties-maven-plugin:1.0-alpha-2:write-project-properties (execution: default, phase: process-resources) I would like Eclipse to execute these lifecycle phases at

What methods are invoked in the Activity Lifecycle in the following cases:

由 风格不统一 提交于 2019-11-29 23:13:41
Let's say I have a Hello World single Activity application. I start this application. What methods are invoked in each case: Home button is pressed: ? Back button is pressed: ? Phone call is received: ? What methods are invoked once the user starts the application again via the app icon (assuming the OS hasn't had a "other apps need memory condition"): Home button was pressed: ? Back button was pressed: ? Phone call was received: ? Thanks all. Edit: Extra Credit: How can the user invoke onPause without invoking onStop ? both pressing home button and receiving a call don't remove the activity

Appropriate lifecycle for repository classes using Castle Windsor

由 微笑、不失礼 提交于 2019-11-29 16:01:16
When I started with Windsor I thought DI would be simple. Now it's causing me more and more confusion. A repository strikes me as a class with a singleton lifecycle. I should have a single instance of a FooRepository to load and save Foos to the database during the application's lifetime. However, each repository holds a reference to a UnitOfWork, which does the dirty checking, works with the database etc. The UnitOfWork has a lifecycle of PerWebRequest - it makes no sense at all for the UnitOfWork to be a singleton, as a singleton instance could (for example) flush the changes made by several

最近在网上看到一篇介绍maven基础知识的文章，觉得对初学Maven的 朋友一定有帮助。水平有限，翻译的不好，请大家见谅。 介绍 在处理WEB应用的时候，最终使用的工程文件是以War包的形式交付。Maven编译系统可以轻松的创建War包。接下来就让我们看看Maven是如何把一个源文件的工程转换成War包的。 Maven 版本 Apache Maven 3.0.4 工程实例 让我们来看看这个非常典型的Maven化的WEB工程 对应的POM.xml如下： <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>mygroup.com</groupId> <artifactId>myprojectname</artifactId> <packaging>war</packaging> <version>1.0-SNAPSHOT</version> <name
