SpringBoot 应用打包

单个 Jar 包

全部依赖集成到一个 jar 包中，且 jar 包可以直接执行。

方式一：parent 依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.1.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
  </parent>
  <groupId>geektime.demo</groupId>
  <artifactId>helloworld</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <name>HelloWorld</name>
  <description>Demo project for Spring Boot</description>

  <properties>
    <java.version>1.8</java.version>
  </properties>

  <dependencies>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
      </dependency>
      <dependency>
        <groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-test</artifactId>
	<scope>test</scope>
      </dependency>
  </dependencies>

  <build>
    <plugins>
      <plugin>
	<groupId>org.springframework.boot</groupId>
	  <artifactId>spring-boot-maven-plugin</artifactId>
      </plugin>
    </plugins>
  </build>

</project>
​

方式二：dependencyManagement

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  
  <modelVersion>4.0.0</modelVersion>

  <groupId>geektime.demo</groupId>
  <artifactId>helloworld</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <name>HelloWorld</name>
  <description>Demo project for Spring Boot</description>

  <properties>
    <java.version>1.8</java.version>
  </properties>

  <dependencyManagement>
    <dependencies>
      <dependency>
	<groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-dependencies</artifactId>
	<version>2.1.1.RELEASE</version>
	<type>pom</type>
	<scope>import</scope>
      </dependency>
    </dependencies>
  </dependencyManagement>

  <dependencies>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-test</artifactId>
      <scope>test</scope>
    </dependency>
  </dependencies>

  <build>
    <plugins>
      <plugin>

	<executions>
	  <execution>
	    <goals>
	      <goal>repackage</goal>
	    </goals>
	  </execution>
	</executions>
      </plugin>
    </plugins>
  </build>

</project>

分目录部署包

jar 包，依赖包，配置文件分目录独立部署，修改配置文件无需重新打包。

appassembler-maven-plugin

pom 中配置

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>appassembler-maven-plugin</artifactId>
    <version>1.10</version>
    <configuration>
        <configurationDirectory>conf</configurationDirectory>  
        <configurationSourceDirectory>src/main/resources</configurationSourceDirectory>  
        <copyConfigurationDirectory>true</copyConfigurationDirectory>  
        <includeConfigurationDirectoryInClasspath>true</includeConfigurationDirectoryInClasspath>  
        <assembleDirectory>${project.build.directory}/app</assembleDirectory>  
        <extraJvmArguments>-Xms128m</extraJvmArguments>  
        <binFileExtensions>  
            <unix>.sh</unix>  
        </binFileExtensions>  
        <platforms>
            <platform>windows</platform>
            <platform>unix</platform>
        </platforms>
        <repositoryName>lib</repositoryName>
        <programs>
            <program>
                <id>app</id>
                <mainClass>com.app.Main</mainClass>
                <jvmSettings>
                    <extraArguments>
                        <extraArgument>-server </extraArgument>
                        <extraArgument>-Xmx2G</extraArgument>
                        <extraArgument>-Xms2G</extraArgument>
                    </extraArguments>
                </jvmSettings>
            </program>
        </programs>
    </configuration>
</plugin>
​

maven 命令

mvn package appassembler:assemble
​

这样子就可以自动生成整个依赖文件，配置文件和运行脚本了。

配置说明

• configurationDirectory：生成配置文件路径
• configurationSourceDirectory：配置文件原路径，默认为 src/main/config
• assembleDirectory:整体包目录
• extraJvmArguments：jvm 参数
• binFileExtensions：生成脚本的后缀
• platforms：生成哪几种平台
• repositoryName：依赖包目录，默认 repo
• programs：这个必须参数，启动的主 class
