开发环境，经常需要发布，由于依赖已经固定了，所以可以采取分离打包的形式。

首先，更改pom.xml的build

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <fork>true</fork>
                <finalName>${project.build.finalName}</finalName>
                <!--解决windows命令行窗口中文乱码-->
                <jvmArguments>-Dfile.encoding=UTF-8</jvmArguments>
                <layout>ZIP</layout>
                <includes>
                    <!--这里是填写需要包含进去的jar，
                        必须项目中的某些模块，会经常变动，那么就应该将其坐标写进来
                        如果没有则non-exists ，表示不打包依赖
                    -->
                    <include>
                        <groupId>non-exists</groupId>
                        <artifactId>non-exists</artifactId>
                    </include>
                </includes>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
        <!--此插件用于将依赖包抽出-->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <executions>
                <execution>
                    <id>copy-dependencies</id>
                    <phase>package</phase>
                    <goals>
                        <goal>copy-dependencies</goal>
                    </goals>
                    <configuration>
                        <outputDirectory>${project.build.directory}/lib</outputDirectory>
                        <excludeTransitive>false</excludeTransitive>
                        <stripVersion>false</stripVersion>
                        <includeScope>runtime</includeScope>
                    </configuration>
                </execution>
            </executions>
        </plugin>
        <plugin>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
                <skip>true</skip>
            </configuration>
        </plugin>
    </plugins>
</build>

执行mvn clean package后的效果如下

之后，就可以启动了。启动命令需要带上依赖

java -Dloader.path=./lib -jar xxx.jar
