What is Maven environment isolation

As the name implies, Maven environment isolation is to separate the environment under development to facilitate development. This is used quite a lot in the actual project, if your project uses Maven build but does not use environmental isolation, please immediately do environmental isolation of the project, believe me, you will come back to follow me!

Project environment

We are generally divided into the following four categories

Local development environment (Local)

Development environment (Dev)

Test environment (Beta)

Online environment (Prod)

Again, Maven helps us avoid the disadvantages of manual modification, that is, easy to make mistakes, easy to compile in different environments, packaging, deployment and so on.

Maven environment isolation configuration

1. Add under the build node in pom.xml

Src/main/resources.$ {deploy.type} * .jsp src/main/resources

2. Add profiles node to pom.xml

Dev true dev beta beta prod prod

3. According to the profile, we need to create a new resource folder.

4. Add the packaging command when compiling and packaging-P$ {environment identification}

Mvn clean package-Dmaven.test.skip=true-Pdev

After that, you can see the corresponding environment configuration in target. It is important to note that the choice of Profiles under Maven Project is the version at the time of release, that is, the environment parameters when publishing to Tomcat.
