SpringCloud maven-assembly-plugin SpringCloud maven-assembly-plugin 多级目录打包的实现
Mr-Wanter 人气:01、spring-boot-maven-plugin
springboot默认打包工具为spring-boot-maven-plugin
pom配置:
<plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <mainClass>com.gsafety.bg.enterprise.EnterpriseApplication</mainClass> <layout>ZIP</layout> <!-- 打增量包时需要includes部分, 要打全量包删除includes --> <includes> <include> <groupId>com.gsafety.bg</groupId> <artifactId>enterprise-controller</artifactId> </include> <include> <groupId>com.gsafety.bg</groupId> <artifactId>enterprise-service</artifactId> </include> <include> <groupId>com.gsafety.bg</groupId> <artifactId>enterprise-dao</artifactId> </include> </includes> </configuration> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin>
打包后的目录结构:
BOOT-INF内包含目录:lib(enterprise-service-1.0.0.jar、enterprise-dao-1.0.0.jar、enterprise-controller-1.0.0.jar)、classes、classpath.idx
2、maven-assembly-plugin
maven-assembly-plugin 插件的主要作用是允许用户将项目输出与它的依赖项、模块、站点文档、和其他文件一起组装成一个可分发的归档文件,简单的说,就是自定义打包的工具,有自己的配置文件(Assembly描述符文件)。微服务使用这个插件的概率比较高,平时普通的项目不需要这样的实现方式。
pom配置:
<plugin> <artifactId>maven-assembly-plugin</artifactId> <version>2.4.1</version> <configuration> <finalName>enterprise</finalName> <encoding>utf-8</encoding> <descriptors> <descriptor>src/main/assembly/assembly.xml</descriptor> </descriptors> </configuration> <executions> <execution> <id>make-assembly</id> <phase>package</phase> <goals> <goal>single</goal> </goals> </execution> </executions> </plugin>
assembly.xml
全部可设置节点可参考官网:http://maven.apache.org/plugins/maven-assembly-plugin/assembly.html
<assembly> <id>1.0</id> <formats> <format>tar.gz</format> </formats> <includeBaseDirectory>true</includeBaseDirectory> <!-- 项目所需lib包--> <!-- <dependencySets>--> <!-- <!–把依赖都打包进libs文件夹–>--> <!-- <dependencySet>--> <!-- <useProjectArtifact>true</useProjectArtifact>--> <!-- <outputDirectory>libs</outputDirectory>--> <!-- <scope>runtime</scope>--> <!-- </dependencySet>--> <!-- </dependencySets>--> <fileSets> <!--打包启动文件到deploy目录--> <fileSet> <!--需要打包的文件所在目录 即start.sh--> <directory>src/main/assembly/bin</directory> <!--要打包到的地址--> <outputDirectory>deploy</outputDirectory> <!--linux权限--> <fileMode>0755</fileMode> </fileSet> <!--打包可执行jar到application-server目录--> <fileSet> <directory>target</directory> <outputDirectory>application-server</outputDirectory> <includes> <include>*.jar</include> </includes> </fileSet> <!--打包src/main/resources到logs/enterprise目录--> <fileSet> <directory>src/main/resources</directory> <outputDirectory>logs/enterprise</outputDirectory> <fileMode>0755</fileMode> <!--打包不包含src/main/resources所有文件,即生成logs/enterprise空目录--> <excludes> <exclude>**/*</exclude> </excludes> </fileSet> </fileSets> </assembly>
打包后的目录结构:
查看application-server文件夹内可执行文件解压目录:
发现与spring-boot-maven-plugin打包后的目录不一致,明显缺少lib内的三个jar和其他一些文件
3、maven-assembly-plugin打包后的可执行文件缺失lib问题
修改pom文件:
<build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <mainClass>com.gsafety.bg.enterprise.EnterpriseApplication</mainClass> <layout>ZIP</layout> <!-- 打增量包时需要includes部分, 要打全量包删除includes --> <includes> <include> <groupId>com.gsafety.bg</groupId> <artifactId>enterprise-controller</artifactId> </include> <include> <groupId>com.gsafety.bg</groupId> <artifactId>enterprise-service</artifactId> </include> <include> <groupId>com.gsafety.bg</groupId> <artifactId>enterprise-dao</artifactId> </include> </includes> </configuration> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin> <!-- 生成项目依赖到lib本地,并设置需要排除的jar--> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <executions> <execution> <id>copy-dependencies</id> <phase>prepare-package</phase> <goals> <goal>copy-dependencies</goal> </goals> <configuration> <outputDirectory>../../../lib</outputDirectory> <!-- 需要排除的jar的 groupId --> <excludeArtifactIds> enterprise-controller,enterprise-service,enterprise-dao </excludeArtifactIds> </configuration> </execution> </executions> </plugin> <plugin> <artifactId>maven-assembly-plugin</artifactId> <version>2.4.1</version> <configuration> <finalName>enterprise</finalName> <encoding>utf-8</encoding> <descriptors> <descriptor>src/main/assembly/assembly.xml</descriptor> </descriptors> </configuration> <executions> <execution> <id>make-assembly</id> <phase>package</phase> <goals> <goal>single</goal> </goals> </execution> </executions> </plugin> </plugins> </build>
即plugins先引用spring-boot-maven-plugin 后引用maven-assembly-plugin,这样spring-boot-maven-plugin会将enterprise-service-1.0.0.jar、enterprise-dao-1.0.0.jar、enterprise-controller-1.0.0.jar三个jar打包到lib中,打包后maven-assembly-plugin就会将其打包进enterprise-1.0.tar.gz。
这样enterprise-1.0.tar.gz内就包含了启动文件(deploy)、可执行文件(application-server/enterprise-main-1.0.0.jar)、日志目录(logs/enterprise),符合目前项目部署的目录结构。
