maven 命令：clean package -Dmaven.test.skip=true -P deta
1.命令很简单是：清class文件，打包构建，跳过测试，注意最后一个 -P product，-P maven 会激活项目下的pom.xml配置的<profiles>标签下id为deta
<profiles>
<profile>
<!-- 本地开发环境 -->
<id>dev</id>
<properties>
<profiles.active>dev</profiles.active>
</properties>
<activation>
<!-- 设置默认激活这个配置 -->
<activeByDefault>true</activeByDefault>
</activation>
</profile>
<profile>
<!-- 发布环境 -->
<id>release</id>
<properties>
<profiles.active>release</profiles.active>
</properties>
</profile>
<profile>
<!-- 测试环境 -->
<id>beta</id>
<properties>
<profiles.active>beta</profiles.active>
</properties>
</profile>
</profiles>
2.使用占位符上面配置定义的${profiles.active}进行资源过滤
<build>
<resources>
<resource><!--不参与打包和替换的资源文件-->
<directory>src/main/resources</directory>
<filtering>true</filtering>
<includes>
<include>**/*.yml</include>
<include>**/*.yaml</include>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
</resource>
<resource><!--不参与打包和替换的资源文件-->
<directory>src/main/resources</directory>
<filtering>false</filtering>
<excludes>
<exclude>**/*.pdf</exclude>
<exclude>**/*.txt</exclude>
</excludes>
</resource>
</resources>
<filters>
<filter>src/main/resources/config/${profiles.active}/log-profile.properties</filter>
</filters>
需要自定义配置filter插件的分隔符${}。否则默认会使用@作为分隔符。
<plugin><!-- 需要自定义 delimiter-->
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.6</version>
<configuration>
<encoding>UTF-8</encoding>
<delimiters>
<delimiter>${*}</delimiter>
</delimiters>
<useDefaultDelimiters>false</useDefaultDelimiters>
</configuration>
</plugin>
总结
激活profile其实就是激活<profile>标签的id，给properties的属性赋值。
通过filters标签的源文件，对sources 的 input文件集进行内容替换。
注意：需要自定义分隔符。
整个pom配置参考

总结
只替换，不重新编译技巧
最后，排查中还有一个小技巧，不要用mvn install或者mvn package这种操作来重新运行，因为会很慢很耗时，直接用mvn clean resources:resources就可以了，它只复制&替换配置目录下的文件，非常地快
