This article mainly explains "how Maven filters different environment profiles". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let Xiaobian take you to learn "Maven how to filter different environment configuration files"!

background introduction

There are at least three environments for development, testing and production, and the configuration information required is definitely different, so you can specify which configuration file to use when packaging.

If the test environment uses: mvn package -P test, then the value of ${env} is test. When packaging, the placeholder ${xx.xx} of the configuration file under src/main/resources will be replaced by the xx.xx position corresponding to test.properties.

uses examples

First add pom.xml configuration information, filter specifies environment configuration file directory, resources specifies resource file directory to replace, profiles specifies matching files corresponding to different environments.

For example, spring-beans.xml is a resource configuration file in which test.name is replaced by placeholders during packaging.

test.properties content is: test.name=hi,test, other files are similar.

The entire maven structure

So when I finish packing mvn package -P test, I go to check the contents of spring-beans.xml in the packed package, and it will become the following replacement completed.

In this way, the configuration of different environment resources is realized, and it is determined at the packaging compilation time.

If the development environment uses: mvn package -P dev, the placeholder ${xx.xx} of the configuration file under src/main/resources will be replaced by the xx.xx position corresponding to dev.properties.

At this point, I believe everyone has a deeper understanding of "how Maven filters different environment profiles," so let's actually operate it! Here is the website, more related content can enter the relevant channels for inquiry, pay attention to us, continue to learn!
