如何从spring boot jar中排除资源文件？ [英] How to exclude resource file from spring boot jar?

问题描述

我正在使用 maven-spring-boot 插件来生成jar。我有多个配置资源文件（ application-production.yml，application-test.yml，application-development.yml ）。

I am using maven-spring-boot plugin for jar generating. I have multiple resource files with configuration (application-production.yml, application-test.yml, application-development.yml).

事实上，当我为客户生成版本时，我想排除开发和测试文件。是否可以在 maven-spring-boot 插件中排除资源文件？

Thing is, when I generate the release for our customers, I would like to exclude development and test files. Is it possible to exclude resource file in maven-spring-boot plugin?

我试过这个：

        <build>
            <resources>
                <resource>
                    <directory>src/main/resources</directory>
                    <excludes>
                        <exclude>application-dev*</exclude>
                        <exclude>application-test*</exclude>
                    </excludes>
                </resource>
            </resources>
        </build>

但maven插件使用自己的脚本进行资源管理（例如@ val @ replacement等）如果将它添加到pom中，则在打包期间失败：

but the maven plugin uses its own scripts for resource management (for example @val@ replacing etc.) and it fails during packaging if it is added to pom:

Caused by: org.yaml.snakeyaml.scanner.ScannerException: while scanning for the next token
found character @ '@' that cannot start any token. (Do not use @ for indentation)
 in 'reader', line 4, column 18:
    project.version: @project.version@

没有它，它运作正常。

推荐答案

而不是使用maven-spring-boot插件使用maven-resource插件和maven配置文件：

Instead of using maven-spring-boot plugin use maven-resource plugin and maven profiles:

<profiles>
  <profile>
    <id>prod</id>
    <build>
      <resources>
        <resource>
          <filtering>true</filtering>
          <directory>[your directory]</directory>
          <excludes>
            <exclude>[non-resource file #1]</exclude>
            <exclude>[non-resource file #2]</exclude>
            <exclude>[non-resource file #3]</exclude>
            ...
            <exclude>[non-resource file #n]</exclude>
          </excludes>
        </resource>
      </resources>
    </build>
  </profile>
</profiles>

确保指定< filtering> true< / filtering> 选项。

为每个环境创建一个配置文件并过滤这些文件。

Create one profile for each environment and filter those files.

确保使用正确的配置文件执行maven：

Make sure to execute maven with the proper profile:

mvn clean install -P prod
