Maven

多环境变量配置

在SpringCloud多模块微服务项目中，在父pom配置profile实现多套环境，同时也要重写build标签，定位要过滤替换环境变量值的配置文件

  1. <profiles>
  2.   <profile>
  3.     <id>dev</id>
  4.     <properties>
  5.       <!--                环境标识，需要与配置文件的名称相对应-->
  6.       <profiles.active>dev</profiles.active>
  7.     </properties>
  8.     <activation>
  9.       <!--                默认环境-->
  10.       <activeByDefault>true</activeByDefault>
  11.     </activation>
  12.   </profile>
  13.   <profile>
  14.     <id>uat</id>
  15.     <properties>
  16.       <!--                环境标识，需要与配置文件的名称相对应-->
  17.       <profiles.active>uat</profiles.active>
  18.     </properties>
  19.   </profile>
  20.   <profile>
  21.     <id>prod</id>
  22.     <properties>
  23.       <!--                环境标识，需要与配置文件的名称相对应-->
  24.       <profiles.active>prod</profiles.active>
  25.     </properties>
  26.   </profile>
  27. </profiles>

配置好该项后可以在IDEA中的Maven中看到对应的环境变量值，选中激活当前的环境变量即可

在配置文件引用Maven环境变量值

  1. spring:
  2.   application:
  3.     name: eureka-server
  4.   profiles:
  5.     active: @profiles.active@
  6. logging:
  7.   level:
  8.     root: info

配置Maven编译时需要替换环境变量值的过滤的文件类型

  1. <build>
  2.   <finalName>${project.name}-${project.version}</finalName>
  3.   <resources>
  4.     <resource>
  5.       <directory>${basedir}/src/main/resources</directory>
  6.       <filtering>true</filtering>
  7.       <includes>
  8.         <include>**/*.xml</include>
  9.         <include>**/*.yml</include>
  10.         <include>**/*.yaml</include>
  11.         <include>**/*.properties</include>
  12.       </includes>
  13.     </resource>
  14.   </resources>
  15. </build>

注意事项

在自定义build标签后，Maven编译时会根据自定义的过滤文件类型，如果不配置忽略过滤的文件，则可能会发生意想不到的后果。

  1. <build>
  2.   <finalName>${project.name}-${project.version}</finalName>
  3.   <resources>
  4.     <resource>
  5.       <directory>src/main/resources</directory>
  6.       <filtering>true</filtering>
  7.       <includes>
  8.         <include>**/*.yml</include>
  9.       </includes>
  10.     </resource>
  11.     <resource>
  12.       <directory>src/main/resources</directory>
  13.       <filtering>false</filtering>
  14.       <includes>
  15.         <include>**/*.xml</include>
  16.         <include>**/*.ttf</include>
  17.         <include>**/*.jpg</include>
  18.         <include>**/*.png</include>
  19.         <include>**/*.ftl</include>
  20.       </includes>
  21.     </resource>
  22.   </resources>
  23.   <plugins>
  24.     <plugin>
  25.       <groupId>org.springframework.boot</groupId>
  26.       <artifactId>spring-boot-maven-plugin</artifactId>
  27.     </plugin>
  28.   </plugins>
  29. </build>

如：

不配置过滤字体文件，编译后的字体文件不能正常使用

双击编译后的字体

在使用itext的项目中具体报错为：
