maven打包dir目录暴露配置文件

起因

在springboot框架下，打包项目发布最开始打包为整包，然后使用java -jar xxx.jar --spring.profiles.active=w2n的命令来启动。 但是之后更新项目时，都是以全量更新的方式，这样做如果只是修改了一点点代码需要更新的话，也得发一个全量包。如是做法，是不优雅的。所以 特此寻找到maven的打包插件assembly。

主要内容

1.在打包的maven模块pom.xml中，添加如下配置

<resources>
    <!-- 复制资源 -->
    <resource>
        <directory>src/main/resources</directory>
        <includes>
            <include>**/*</include>
        </includes>
    </resource>
</resources>
<plugins>
    <!-- 设置源文件编码方式 -->
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
            <source>1.7</source>
            <target>1.7</target>
            <encoding>UTF-8</encoding>
        </configuration>
    </plugin>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jar-plugin</artifactId>
        <version>2.6</version>
        <!-- The configuration of the plugin -->
        <configuration>
            <!-- Configuration of the archiver -->
            <archive>

                <!--
                    生成的jar中，不要包含pom.xml和pom.properties这两个文件
                -->
                <addMavenDescriptor>false</addMavenDescriptor>

                <!-- Manifest specific configuration -->
                <manifest>
                    <!--
                        是否要把第三方jar放到manifest的classpath中
                    -->
                    <addClasspath>true</addClasspath>
                    <!--
                       生成的manifest中classpath的前缀，因为要把第三方jar放到lib目录下，所以classpath的前缀是lib/
                   -->
                    <classpathPrefix>lib/</classpathPrefix>
                    <!--
                        应用的main class
                    -->
                    <mainClass>com.inspur.proxy.ZscProxyApplication</mainClass>
                </manifest>
                <manifestEntries>
                    <Class-Path>./</Class-Path>
                </manifestEntries>
            </archive>
            <!--
                过滤掉不希望包含在jar中的文件
            -->
            <!--<excludes>-->
            <!--<exclude>${project.basedir}/xml/*</exclude>-->
            <!--</excludes>-->
            <excludes>
                <exclude>config/**</exclude>
                <exclude>spring/**</exclude>
                <exclude>*.properties</exclude>
            </excludes>
        </configuration>
    </plugin>

    <!-- The configuration of maven-assembly-plugin -->
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-assembly-plugin</artifactId>
        <version>2.4</version>
        <!-- The configuration of the plugin -->
        <configuration>
            <!-- Specifies the configuration file of the assembly plugin -->
            <descriptors>
                <descriptor>src/main/resources/assembly/assembly.xml</descriptor>
            </descriptors>
        </configuration>
        <executions>
            <execution>
                <id>make-assembly</id>
                <phase>package</phase>
                <goals>
                    <goal>single</goal>
                </goals>
            </execution>
        </executions>
    </plugin>
</plugins>

2.配置插件的assembly.xml文件

<assembly>
    <id>ga</id>
    <includeBaseDirectory>false</includeBaseDirectory>
    <!-- 最终打包成一个用于发布的zip文件 -->
    <formats>
        <format>dir</format>
    </formats>
    <!-- Adds dependencies to zip package under lib directory -->
    <dependencySets>
        <dependencySet>
            <!--
               不使用项目的artifact，第三方jar不要解压，打包进zip文件的lib目录
           -->
            <useProjectArtifact>false</useProjectArtifact>
            <outputDirectory>lib</outputDirectory>
            <unpack>false</unpack>
        </dependencySet>
    </dependencySets>

    <fileSets>
        <!-- 把项目相关的说明文件，打包进zip文件的根目录 -->
        <!--<fileSet>-->
        <!--<directory>${project.basedir}</directory>-->
        <!--<outputDirectory>/</outputDirectory>-->
        <!--</fileSet>-->

        <!-- 把项目的配置文件，打包进zip文件的config目录 -->
        <fileSet>
            <directory>src/main/resources</directory>
            <outputDirectory>/config</outputDirectory>
            <includes>
                <!--<include>*.xml</include>-->
                <include>*.properties</include>
            </includes>
            <excludes>
                <exclude>log4j.properties</exclude>
            </excludes>
        </fileSet>
        <fileSet>
            <directory>src/main/resources</directory>
            <outputDirectory>/</outputDirectory>
            <includes>
                <!--<include>*.xml</include>-->
                <include>log4j.properties</include>
            </includes>
        </fileSet>
        <!--<fileSet>
            <directory>src/main/resources/spring</directory>
            <outputDirectory>/spring</outputDirectory>
            <includes>
                <include>*</include>
            </includes>
        </fileSet>-->
        <fileSet>
            <directory>src/main/resources/config</directory>
            <outputDirectory>/config</outputDirectory>
            <includes>
                <include>*.properties</include>
            </includes>
        </fileSet>
        <!-- 把项目自己编译出来的jar文件，打包进zip文件的根目录 -->
        <fileSet>
            <directory>${project.build.directory}</directory>
            <outputDirectory></outputDirectory>
            <includes>
                <include>*.jar</include>
            </includes>
        </fileSet>
    </fileSets>
</assembly>
