maven之SpringBoot如何打包呢?
下文笔者讲述maven项目打包的方法及示例分享,如下所示
配置项目启动类
将当前项目java目录下除了java文件打进jar包呢
maven打包-我们需借助相应build插件,即可实现maven打包，如下所示
maven-compiler-plugin:负责编译源码 spring-boot-maven-plugin:负责编译springbootjar maven-jar-plugin:负责将项目依赖的jar写到MANIFEST.MF文件 maven-dependency-plugin:负责导出项目依赖的jar maven-resources-plugin:负责导出项目配置文件例:
springboot全量打包项目为jar包pom配置
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<!--设置为true，以便把本地的system的jar也包括进来-->
<includeSystemScope>true</includeSystemScope>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
springboot打包项目为jar包和lib包分离的pom配置(其他的配置文件resources还是在jar包)
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<!--项目的启动类-->
<mainClass>org.jeecg.JeecgApplication</mainClass>
<!--layout 是为了 springboot jar简化后能够加载第三方jar包目录，如果没加入这句话，在待会儿启动时，会报错-->
<layout>ZIP</layout>
<!--解决windows命令行窗口中文乱码-->
<jvmArguments>-Dfile.encoding=UTF-8</jvmArguments>
<!--不包含任何jar包-->
<includes>
<include>
<groupId>nothing</groupId>
<artifactId>nothing</artifactId>
</include>
</includes>
</configuration>
<!--idea打jar包，提示 jar包中没有主清单属性 - 解决办法
1.是 <goal>repackage</goal>起了作用，内容如下：-->
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
配置项目启动类
关联lib包下面的jar包
启动项目后才能关联找到
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<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 -->
<!-- MANIFEST.MF 中 Class-Path 各个依赖加入前缀 -->
<classpathPrefix>lib/</classpathPrefix>
<!--指定jar程序入口-->
<mainClass>org.jeecg.JeecgApplication</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
Maven打包jar与lib依赖包分离
addClasspath：表示需要加入到类构建路径
classpathPrefix：指定生成的Manifest文件中Class-Path依赖lib前面都加上该前缀路径，构建出lib/xx.jar
mainClass：表示项目的启动类。
<build>
<finalName>${project.artifactId}</finalName>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<!-- 是否要把第三方jar加入到类构建路径 -->
<addClasspath>true</addClasspath>
<!-- 外部依赖jar包的最终位置 -->
<!-- MANIFEST.MF 中 Class-Path 各个依赖加入前缀 -->
<classpathPrefix>lib/</classpathPrefix>
<!--指定jar程序入口-->
<mainClass>com.baidu.test.App</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
<!--拷贝依赖到jar外面的lib目录-->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>prepare-package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<!-- 拷贝项目依赖包到lib/目录下 -->
<outputDirectory>${project.build.directory}/lib</outputDirectory>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>false</overWriteSnapshots>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
拷贝项目依赖的jar包到target目录下lib中
<build>
<plugins>
<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>
拷贝项目resource包下的内容到target目录下resource中
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<executions>
<!-- 复制配置文件 -->
<execution>
<id>copy-resources</id>
<phase>package</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<resources>
<resource>
<directory>src/main/resources</directory>
<!--<includes>-->
<!--<include>*.properties</include>-->
<!--<include>*.yml</include>-->
<!--<include>*/*.properties</include>-->
<!--<include>*/*.properties</include>-->
<!--</includes>-->
</resource>
</resources>
<outputDirectory>${project.build.directory}/resource/</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
pom.xml文件完整瘦身配置
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<!-- 剔除配置文件 -->
<excludes>
<exclude>*.properties</exclude>
<exclude>*.yml</exclude>
<exclude>*/*.properties</exclude>
<exclude>*/*.yml</exclude>
<exclude>*/*.ftl</exclude>
</excludes>
<archive>
<manifest>
<!-- 是否要把第三方jar加入到类构建路径 -->
<addClasspath>true</addClasspath>
<!-- 外部依赖jar包的最终位置 -->
<classpathPrefix>lib/</classpathPrefix>
<!--指定jar程序入口-->
<mainClass>org.jeecg.JeecgApplication</mainClass>
</manifest>
<manifestEntries>
<!--MANIFEST.MF 中 Class-Path 加入自定义路径，多个路径用空格隔开，
此处是加入resource资源访问路径-->
<!--此处resources文件夹的内容，需要maven-resources-plugin插件补充上-->
<Class-Path>./resources/</Class-Path>
<!--类似引入第三方包，加入 lib/example-1.0.jar lib/jna-1.0.jar 注意需要有空格，
如果不想这样加入第三方包的引用，就直接将第三方包打包到本地仓库，然后dependency依赖进来-->
<!--<Class-Path>./resources/ lib/example-1.0.jar lib/jna-1.0.jar</Class-Path>-->
</manifestEntries>
</archive>
<outputDirectory>${project.build.directory}</outputDirectory>
</configuration>
</plugin>
<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>
<!-- 拷贝项目依赖包到lib/目录下 -->
<outputDirectory>${project.build.directory}/lib</outputDirectory>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>false</overWriteSnapshots>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</execution>
</executions>
</plugin>
<plugin>

<!--</includes>-->
</resource>
</resources>
<outputDirectory>${project.build.directory}/resources/</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
将当前项目java目录下除了java文件打进jar包呢
在build和plugins之间先设置策略如下
<build>
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>true</filtering>
</resource>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.yml</include>
<include>**/*.xml</include>
</includes>
<filtering>true</filtering>
</resource>
</resources>
<finalName>poi</finalName>
<plugins>
注意事项:
**:表示多级目录
*:表示一级目录
