Is there any way to change a properties file that is in my classpath?

阅读更多关于 Is there any way to change a properties file that is in my classpath?

问题 I have a properties file that is in my classpath. My requirement is to change some properties in this file based on some inputs I get from arguments. The nature of arguments decide whether I need to change the properties and if yes which properties to change. The problem is that all classpath entries are loaded at the application startup time, so changing from within my application would not have any effect. How do I overcome this problem? One possible solution I can think of is to not add

Create path from javascript object property

阅读更多关于 Create path from javascript object property

问题 Let's say I've got the following javascript object var obj = { a:{ b:"value", c:{ d:"value2" } } } What function would, when input with the "d" object (for example, function getPath(obj, d) ), output the "a.c.d" string? I've tried various things including object-path, but it doesn't seem to be designed for that 回答1: You could use an iterative and recursive approach. function getPath(object, key) { function iter(o, p) { if (typeof o === 'object') { return Object.keys(o).some(function (k) {

IDEA开发spring boot应用时 application.yml 或 application.properties 自定义属性提示

阅读更多关于 IDEA开发spring boot应用时 application.yml 或 application.properties 自定义属性提示

/*--> */ /*--> */ 在使用spring boot开发过程中，经常会定义一些应用自己的属性，直接写到application配置文件中使用@Value注解进行使用，这样使用也没有什么问题。不过我认为更优雅的方式是定义自己的属性类统一管理，这样在idea中，既能自动提示，又能对配置进行分类管理，显得有条不紊，下面是具体的配置步骤。第一步：添加依赖（分为maven和gradle两种方式） 1.1 如果你使用的是maven 增加依赖 <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-configuration-processor</artifactId> </dependency> 1.2 如果你使用的是gradle 增加依赖并且配置annotationProcessor compileOnly 'org.springframework.boot:spring-boot-configuration-processor' annotationProcessor ‘org.springframework.boot:spring-boot-configuration-processor’ 第二步：创建配置属性类 @Data

How to mock a property setter on a PartialMock using Rhino Mocks

阅读更多关于 How to mock a property setter on a PartialMock using Rhino Mocks

问题 I'd like to prevent the real setter code being invoked on a property on a partial class. What is the syntax for this? My current code to stub out the getter (I'd like to also stub out the setter): var user = MockRepository.GeneratePartialMock<User>(ctor params...); user.MyProperty = "blah"; Something like this? user.Stub(u => u.MyProperty).Do(null); 回答1: Here's a 3.5 sample that does what you need (I think your syntax above is 3.1 or 3.2). First, I have a delegate for the property setter call

Preventing breeze.js from creating observables properties on array objects

阅读更多关于 Preventing breeze.js from creating observables properties on array objects

问题 I must be missing something simple, but can't figure it out. I'm retrieving a bunch of lookup tables in 1 Web API call. return EntityQuery.from('Lookups') .noTracking(true) .using(manager).execute() .then(processLookups); In processLookups I'm calling getLocal for each array that was returned. Example: State table datacontext.lookups = { state: getLocal('States', orderBy.state, true), .... } function getLocal(resource, ordering, includeNullos) { var query = EntityQuery.from(resource) .orderBy

Should we declare properties' ivars or let the compiler do it for us? What about weak properties?

阅读更多关于 Should we declare properties' ivars or let the compiler do it for us? What about weak properties?

问题 I'd like to understand if there is any advantage in declaring properties ivars instead of letting the compiler do it for us, considering only to build code for IOS5.. I think that the best practice should be not to declare them, otherwise you should remember of things like declaring ivars as __weak if the corresponding property is declared as weak.. it is necessary to do that, right? Otherwise the weak property is assigned to a strong ivar by default and it is no more weak... 回答1: I usually

What is correct syntax for using vertical bar in CSS?

阅读更多关于 What is correct syntax for using vertical bar in CSS?

问题 I didn't write this CSS and I don't know what to do with this code. #r_constraint{ float:left; height:40px; | height:42px; overflow:hidden; margin:0 27px; width:698px; I'm getting an error on this property " | height:42px; ". Warning: Expected declaration but found '|'. Skipped to next declaration. I looked stackoverflow - what does pipe mean... but wasn't really what I was looking for. So I tried 6.1.1. Type selectors and namespaces, but it appears to be describing using the vertical bar for

Custom Property Default Value & .NET Designer

阅读更多关于 Custom Property Default Value & .NET Designer

问题 What's the best way to avoid (or control) the initialisation by the designer of a heavy custom property in .NET? Sometimes it is important to have a property set to something initially without that setting being acted upon when initially set. In the imaginary example below, I want to achieve the flexibility of having something like UpdateSetting as a property, but not the inconvenience of having the database set to zero every time the application starts up. All I can think of is another
