转载: http://412887952-qq-com.iteye.com/blog/2307104 多环境配置 以上都不是重点,这才是重点,这才是重点,这才是重点,重要的事情说3遍。我们在开发Spring Boot应用时,通常同一套程序会被应用和安装到几个不同的环境,比如:开发、测试、生产等。其中每个环境的数据库地址、服务器端口等等配置都会不同,如果在为不同环境打包时都要频繁修改配置文件的话,那必将是个非常繁琐且容易发生错误的事。 对于多环境的配置,各种项目构建工具或是框架的基本思路是一致的,通过配置多份不同环境的配置文件,再通过打包命令指定需要打包的内容之后进行区分打包,Spring Boot也不例外,或者说更加简单。 在Spring Boot中多环境配置文件名需要满足 application-{profile}.properties 的格式,其中 {profile} 对应你的环境标识,比如: application-dev.properties:开发环境 application-test.properties:测试环境 application-prod.properties:生产环境 至于哪个具体的配置文件会被加载,需要在 application.properties 文件中通过 spring.profiles.active 属性来设置,其值对应 {profile} 值。 如

原文:http://www.importnew.com/29368.html 多环境配置 在开发应用时,常用部署的应用是多个的,比如:开发、测试、联调、生产等不同的应用环境,这些应用环境都对应不同的配置项,比如 swagger 一般上在生产时是关闭的;不同环境数据库地址、端口号等都是不尽相同的,要是没有多环境的自由切换,部署起来是很繁琐也容易出错的。 maven的多环境配置 在没有使用过 springboot 的多环境配置时,原先是利用 maven 的 profile 功能进行多环境配置,这里我简单回顾下。 maven配置 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 <profiles> <profile> <id>dev</id> <activation> <activeByDefault> true </activeByDefault> </activation> <properties> <pom.port> 8080 </pom.port> </properties> </profile> <profile> <id>test</id>

   在我们平常的 java 开发中,会经常使用到很多配制文件( xxx.properties , xxx.xml ),而当我们在本地开发( dev ),测试环境测试( test ),线上生产使用( product )时,需要不停的去修改这些配制文件,次数一多,相当麻烦。现在,利用 maven 的 filter 和 profile 功能,我们可实现在编译阶段简单的指定一个参数就能切换配制,提高效率,还不容易出错 .   profile 可以让我们定义一系列的配置信息,然后指定其激活条件。这样我们就可以定义多个 profile ,然后每个 profile 对应不同的激活条件和配置信息,从而达到不同环境使用不同配置信息的效果 不同环境,工程使用不同端口 pom.xml <profiles> <profile> <id>dev</id> <properties> <port>9105</port> </properties> </profile> <profile> <id>pro</id> <properties> <port>9205</port> </properties> </profile> </profiles> <build> <plugins> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId

Confusion with properties

為{幸葍}努か 提交于 2019-12-29 09:09:38
问题 I am new to using properties, so I put together a simple test as shown below. In my tests, I made two classes "Test1" and "Test2" where each is meant to hold one value. I am attempting to use a property to govern access to the pseudo-hidden "val" attribute. This current test does not restrict any inputs or outputs of the "val" attribute as this program was only meant as a proof of concept. The two test classes shown below yield the same results and are supposed to represent the different

问题 Assume I have a bean DialogBox, with properties for height and width: public class DialogBox { int x; int y; ... } In my applicationContext.xml I would define properties as reasonable defaults: <bean id="dialogbox" class="DialogBox"> <property name="x" value="100"/> <property name="y" value="100"/> </bean> We have multiple clients that use the dialogBox bean, and each wants a custom value for x and y. One route we have discusses is having multiple properties files, one for each client, and

Is it possible to have a getter for a const?

问题 Just curious, is there a way to have a getter for a constant variable? I have a sort of internal version number to ensure that two versions of a library are still speaking the same language, but I'd like the programmer to be able to check what version they're using. Right now I use: private const Int16 protocol_version = 1; public Int16 ProtocolVersion { get { return protocol_version; } } But I'd prefer to do it with just the const if there's a way. 回答1: You could declare a property with only

Possible Duplicate: Properties and Instance Variables in Objective-C 2.0 I'm using properties only for ivars that don't require any real validation when getting or setting a value for a class that I'm authoring.

I use to load properties file using a Property class as described in the URL http://www.exampledepot.com/egs/java.util/Props.html my question is can I use properties within that properties file ? example: test.properties url.main="http://mysite.com" url.games={url.main}/games url.images={url.main}/images . . . is that possible with some other syntax? thanks 回答1: Never seen that before.
