<!-- 3.结构定制化的打包,打包规则定义到一个xml文件中 -->

<configuration>
<descriptors>
<!-- 描述文件路径 -->
<descriptor>src/main/resources/package.xml</descriptor>
</descriptors>
<!-- 打包解压后的目录名:${project.artifactId}是指:项目的artifactId -->
<finalName>${project.artifactId}</finalName>
<!-- 打包压缩包位置 -->
<outputDirectory>${project.build.directory}/</outputDirectory>
</configuration>
<!-- 加上下面这一段,使用 maven package命令,不加则使用mvn assembly-->
<executions>
<execution>
<id>make-assembly</id><!--名字任意 -->
<phase>package</phase><!-- 绑定到package生命周期阶段上 -->
<goals>

例如:
<build>
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
<includes>
<include>application.properties</include>
</includes>
</resource>
<resource>
<directory>src/main/resources</directory>
<filtering>false</filtering>
<excludes>
<exclude>application.properties</exclude>
</excludes>
</resource>
<!-- 最后是取两个配置分别过滤的文件集合的并集。 -->
</resources>
</build>
标签 <directory>
指定资源文件目录;
标签 <include>
指定资源文件目录中,哪些文件被打包。(包含)
标签 <excludes>
指定资源文件目录中,哪些文件不被打包。(排除)
标签 <filtering>
指配置文件中是否需要用变量进行替换实际的值。
# application.properties
application.user=${username111}
application.password=${password222}
文件中使用${keyword}
占位符来标识变量。这时候可以在pom.xml
文件中定义变量的取值:如下
<properties>
<username111>mysql</username111>
<password222>password123</password222>
</properties>
