springboot打jar包【我】

如果打好的jar包在linux上无法运行，找不到main入口，可以改下pom文件，在下面增加build信息：|

 </dependencies>
    <build>
        <!--<plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <includeSystemScope>true</includeSystemScope>
                </configuration>
            </plugin>
        </plugins>-->
        <plugins>
            <!-- 指定启动类，将依赖打成外部jar包 -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <configuration>
                    <archive>
                        <!-- 生成的jar中，不要包含pom.xml和pom.properties这两个文件 -->
                        <addMavenDescriptor>false</addMavenDescriptor>
                        <manifest>
                            <!-- 是否要把第三方jar加入到类构建路径 -->
                            <addClasspath>true</addClasspath>
                            <!-- 外部依赖jar包的最终位置 -->
                            <classpathPrefix>lib/</classpathPrefix>
                            <!-- 项目启动类 -->
                            <mainClass>com.yourstartclass.YourServiceApplication</mainClass>
                        </manifest>
                        <!--<manifestEntries>
                            <Class-Path>${basedir}/../../tydic-ctsku-cloud-tools/tydic-ctsku-cloud-ctcache/lib/*.jar</Class-Path>
                        </manifestEntries>-->
                    </archive>
                </configuration>
            </plugin>
            <!--拷贝依赖到jar外面的lib目录-->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-dependency-plugin</artifactId>
                <executions>
                    <execution>
                        <id>copy-lib</id>
                        <phase>package</phase>
                        <goals>
                            <goal>copy-dependencies</goal>
                        </goals>
                        <configuration>
                            <outputDirectory>target/lib</outputDirectory>
                            <excludeTransitive>false</excludeTransitive>
                            <stripVersion>false</stripVersion>
                            <includeScope>runtime</includeScope>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

然后部署的时候记得把target下生成的 lib目录和jar放到同一个目录下，直接启动jar就可以了。

否则可能出现如下错误：
