在这篇文章中 maven配置多个.properties文件，我们利用maven实现了不同环境使用不同的properties文件，但是有时候properties文件并不太适合一些对象性配置，这时候不得不使用yaml文件，那么问题了，不同的环境怎么使用不同的yaml文件呢？

最简单的思路就是使用maven-resource-plugin,根据环境变量将文件拷贝到resource下面即可：

<plugin>
                <artifactId>maven-resources-plugin</artifactId>
                <executions>
                    <execution>
                        <id>dev</id>
                        <phase>validate</phase>
                        <goals>
                            <goal>copy-resources</goal>
                        </goals>
                        <configuration>
                            <outputDirectory>src/main/resources</outputDirectory>
                            <resources>
                                <resource>
                                    <directory>src/main/env/dev/yaml</directory>
                                    <filtering>true</filtering>
                                </resource>
                            </resources>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>

完整的配置文件如下：

<profiles>

        <!-- 开发环境，默认为开发环境 -->
        <profile>
            <id>dev</id>
            <build>
                <filters>
                    <filter>
                        src/main/env/dev/biz.properties
                    </filter>
                </filters>
                <resources>
                    <resource>
                        <directory>src/main/resources</directory>
                        <filtering>true</filtering>
                    </resource>
                </resources>
                <plugins>
                    <plugin>
                        <artifactId>maven-resources-plugin</artifactId>
                        <executions>
                            <execution>
                                <id>dev</id>
                                <phase>validate</phase>
                                <goals>
                                    <goal>copy-resources</goal>
                                </goals>
                                <configuration>
                                    <outputDirectory>src/main/resources</outputDirectory>

                                            <filtering>true</filtering>
