spring-boot - spring boot 无法读取 application.yml

Question

当我自定义 maven-resources-plugin 配置时，Spring Boot 无法读取 application.yml。因为我想用 pom.xml 中的变量替换 Dockerfile 中的一些字符串，有人知道怎么做吗？非常感谢！

在 dockerfile 我想替换下面的这些字符串

....
ADD ./@project.build.finalName@.jar /root/@project.build.finalName@.jar
ENTRYPOINT ["java", "-jar", "/root/@project.build.finalName@.jar"]

我终于通过这样的配置让它工作了：

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <artifactId>maven-resources-plugin</artifactId>
                <configuration>
                    <!--<outputDirectory>target</outputDirectory>-->
                    <resources>
                        <resource>
                            <directory>src/main/resources</directory>
                            <filtering>true</filtering>
                        </resource>
                        <resource>
                            <directory>k8s</directory>
                            <includes>
                                <include>Dockerfile</include>
                            </includes>
                            <filtering>true</filtering>
                        </resource>
                    </resources>
                </configuration>
            </plugin>
        </plugins>
    </build>

mvn clean package -Dmaven.test.skip=true resources:resources
src/main/resources在 mvn package 时需要
