SpringBoot项目集成maven-shade-plugin

因为项目是基于springboot搭建的，按springboot的教程，打包只需要在pom添加以下即可：

<plugin>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-maven-plugin</artifactId>
</plugin>

但需要用到maven-shade-plugin插件打包，在maven-shade-plugin的dependencies添加spring-boot-maven-plugin即可，集成如下：

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <version>2.1.5.RELEASE</version>
    </dependency>
</dependencies>
<configuration>
    <keepDependenciesWithProvidedScope>true</keepDependenciesWithProvidedScope>
    <createDependencyReducedPom>true</createDependencyReducedPom>
    <filters>
        <filter>
            <artifact>*:*</artifact>
            <excludes>
                <exclude>META-INF/*.SF</exclude>
                <exclude>META-INF/*.DSA</exclude>
                <exclude>META-INF/*.RSA</exclude>
            </excludes>
        </filter>
    </filters>
</configuration>
<executions>
    <execution>
        <phase>package</phase>
        <goals>
            <goal>shade</goal>
        </goals>
        <configuration>
            <transformers>
                <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                    <resource>META-INF/spring.handlers</resource>
                </transformer>
                <transformer implementation="org.springframework.boot.maven.PropertiesMergingResourceTransformer">
                    <resource>META-INF/spring.factories</resource>
                </transformer>
                <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                    <resource>META-INF/spring.schemas</resource>
                </transformer>
                <transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"/>
                <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                    <mainClass>com.xxx.App</mainClass>
                </transformer>
            </transformers>
        </configuration>
    </execution>
</executions>
</plugin>
