maven-resource-plugin的使用

在這篇文章中 maven配置多個.properties文件，我們利用maven實現了不同環境使用不同的properties文件，但是有時候properties文件並不太適合一些對象性配置，這時候不得不使用yaml文件，那麼問題了，不同的環境怎麼使用不同的yaml文件呢？

最簡單的思路就是使用maven-resource-plugin,根據環境變量將文件拷貝到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>

        <!-- 開發環境，默認爲開發環境 -->
        <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>

                                <goals>
                                    <goal>copy-resources</goal>
                                </goals>
