Maven打胖包

全部依赖打入jar包中

不需要的可以去除，如指定入口类路径

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-assembly-plugin</artifactId>
                <version>3.1.0</version>
                <configuration>
                    <archive>
                       <manifest>
                           <!-- 指定入口类路径 -->
                          <mainClass>com.xinxing.Test</mainClass> 
                       </manifest>
                    </archive>
                    <descriptorRefs>
                       <!-- jar包后缀 -->
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                </configuration>
                <!-- 添加此项后，可直接使用mvn package | mvn install 否则需使用mvn package assembly:single -->
                <executions>
                    <execution>
                        <id>make-assembly</id>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

只把指定依赖打入jar包

1.不需要打入的dependency加作用域<scope>provided</scope>即可

2.例：不需要把Mysql打入jar包:

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <scope>provided</scope>
        </dependency>
