1、pom文件的配置

   <!--maven构建-->
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <!-- 添加assembly插件 -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-assembly-plugin</artifactId>
                <version>3.1.1</version>
                <configuration>
                    <descriptors>
                        <!-- 指定assembly描述符文件的路径 -->
                        <descriptor>src/assembly/package.xml</descriptor>
                    </descriptors>
                </configuration>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

2、新建assembly的描述文件

<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3 http://maven.apache.org/xsd/assembly-1.1.3.xsd">
    <id>with-dependencies</id>
    <formats>
        <format>jar</format>
    </formats>
    <includeBaseDirectory>false</includeBaseDirectory>
    <dependencySets>
        <dependencySet>
            <!-- 配置依赖如何打包 -->
        </dependencySet>
    </dependencySets>
    <fileSets>
        <fileSet>
            <!-- 配置外部文件夹如何打包 -->
            <directory>filestore</directory>
            <outputDirectory>${file.separator}/filestore</outputDirectory>
        </fileSet>
    </fileSets>
</assembly>

3、maven打包

最终依赖包以及项目jar包和filestore文件夹等都打到了最后一个jar总包里面了。
