SpringBoot打包分离资源文件

        springboot项目打包时，把资源文件，如配置文件，静态资源文件等分离出来，避免为了修改资源文件时重新打包。

1.pom文件

<build>
        <plugins>
            <!--打包jar-->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <configuration>
                    <!--不打包资源文件-->
                    <excludes>
                        <exclude>*.**</exclude>
                        <exclude>*/*.xml</exclude>
                        <exclude>*/*.html</exclude>
                        <exclude>*/*.yml</exclude>
                    </excludes>
                    <archive>
                        <manifest>
                            <addClasspath>true</addClasspath>
                            <!--MANIFEST.MF 中 Class-Path 加入前缀-->
                            <classpathPrefix>lib/</classpathPrefix>
                            <!--jar包不包含唯一版本标识-->
                            <useUniqueVersions>false</useUniqueVersions>
                            <!--指定入口类-->
                            <mainClass>club.jiajiajia.bulider.ProjectBuilderApplication</mainClass>
                        </manifest>
                        <manifestEntries>
                            <!--MANIFEST.MF 中 Class-Path 加入资源文件目录-->
                            <Class-Path>./resources/</Class-Path>
                        </manifestEntries>
                    </archive>
                    <outputDirectory>${project.build.directory}/res</outputDirectory>
                </configuration>
            </plugin>

            <!--拷贝依赖 copy-dependencies-->

                                <resource>
                                    <directory>src/main/resources</directory>
                                </resource>
                            </resources>
                            <outputDirectory>${project.build.directory}/res/resources</outputDirectory>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

            <!--spring boot repackage，依赖 maven-jar-plugin 打包的jar包 重新打包成 spring boot 的jar包-->
            <plugin>
                <groupId>org.springframework.boot</groupId>

                <configuration>

                        </include>
                    </includes>
                    <layout>ZIP</layout>
                    <!--使用外部配置文件，jar包里没有资源文件-->
                    <addResources>true</addResources>
                    <outputDirectory>${project.build.directory}/res</outputDirectory>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                        <configuration>
                            <!--配置jar包特殊标识 配置后，保留原文件，生成新文件 *-run.jar -->
                            <!--配置jar包特殊标识 不配置，原文件命名为 *.jar.original，生成新文件 *.jar -->
                            <!--<classifier>run</classifier>-->
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

注意    指定入口类 

打包执行完成以后在target目录下会有一个res文件夹，这里面就是项目所有需要的文件。

直接执行命令：

java -jar test.jar
