springboot打包依賴包和組態檔分離

前言：springboot專案打包使用spring-boot-maven-plugin外掛，預設會將依賴包和組態檔統統打進可執行jar檔案中，使得jar檔案太臃腫，則正式環境修改組態檔較麻煩，因此需要將組態檔和依賴jar包分離。如下：

<!-- 構建設定 -->
<build>
    <finalName>${project.name}</finalName>
    <sourceDirectory>src/main/java</sourceDirectory>
    <!-- 控制資原始檔的拷貝 -->
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
                <include>**/*.yml</include>
            </includes>
            <filtering>false</filtering>
            <!--本地註釋掉，伺服器放開-->
            <targetPath>${project.build.directory}/${project.name}/config</targetPath>
        </resource>
        <resource>
            <directory>src/main/bin</directory>
            <targetPath>${project.build.directory}/${project.name}/bin</targetPath>
        </resource>
        <!--<resource>-->
            <!--<directory>src/main/java</directory>-->
            <!--<includes>-->
                <!--<include>**/*.xml</include>-->
            <!--</includes>-->
        <!--</resource>-->
    </resources>
    <plugins>
        <!-- 指定啓動類，將依賴打成外部jar包 -->

                    <addMavenDescriptor>false</addMavenDescriptor>
                    <manifest>
                        <!-- 是否要把第三方jar加入到類構建路徑 -->
                        <addClasspath>true</addClasspath>
                        <!-- 外部依賴jar包的最終位置 -->
                        <classpathPrefix>${project.name}/lib/</classpathPrefix>
                        <mainClass>com.epri.dcloud.data.LoopcloseriskanalyzeApplication</mainClass>

                    <!-- (組態檔外接目錄) -->
