maven3 springboot 几种打包构建方法 assembly

1. all in one

<build>
        <finalName>demo</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <fork>true</fork>
                    <mainClass>com.example.demo.DemoApplication</mainClass>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

启动

java -jar demo.jar

2.个性化，配置文件和jar包分离
pom文件

<plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-resources-plugin</artifactId>
                <version>2.7</version>
                <executions>
                    <execution>
                        <id>copy-resources</id>
                        <phase>install</phase>
                        <goals>
                            <goal>copy-resources</goal>
                        </goals>
                        <configuration>
                            <resources>
                                <resource>
                                    <directory>src/main/resources</directory>
                                    <filtering>false</filtering>
                                </resource>
                            </resources>
                            <outputDirectory>${basedir}/target/demo/conf/</outputDirectory>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <version>2.4</version>
                <executions>
                    <execution>
                        <id>distro-assembly</id>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                        <configuration>
                            <descriptors>
                                <descriptor>assembly.xml</descriptor>
                            </descriptors>
                            <outputDirectory>target</outputDirectory>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>

assembly.xml

<assembly>
    <id>distribution</id>
    <formats>
        <format>tar.gz</format>
    </formats>
    <fileSets>
        <fileSet>
            <directory>${basedir}/target/demo/lib</directory>
            <outputDirectory>/lib</outputDirectory>
        </fileSet>
        <fileSet>
            <directory>${basedir}/src/main/resources</directory>
            <excludes>
                <exclude>package</exclude>
            </excludes>
            <outputDirectory>/conf</outputDirectory>
        </fileSet>
    </fileSets>
    <!-- jar -->
    <dependencySets>
        <dependencySet>
            <useProjectArtifact>true</useProjectArtifact>
            <outputDirectory>lib</outputDirectory>
            <scope>runtime</scope>
        </dependencySet>
    </dependencySets>
</assembly>

linux下启动

java -server -cp conf:.:lib/* com.example.demo.DemoApplication

小窍门，可通过如下命令拼依赖的jar包，可调整jar包依赖顺序

echo *.jar | tr ' ' ':'
