对 Mule Studio 中的属性应用 maven 过滤器

Question

我有一个 mule studio 项目，为此我为不同环境的属性定义了 maven 过滤器。

但是，mule studio 无法为默认环境（本地）应用属性，因此应用程序在启动时失败并出现以下错误。

[02-18 20:24:32] ERROR DefaultMuleApplication [main]: null

有没有人在 MuleStudio 中成功使用过过滤器，或者使用过其他方法来解决这个问题？

Answer 1

如果您在 pom.xml 中定义了一个配置文件（或者如果您喜欢在 settings.xml 中）并提到应该为您加载具有特定环境所需过滤器属性的构建标签，您可以在运行 mvn package 时验证这一点并在 jar 内部查看以检查属性文件是否已打包。因此，在下面为您提供帮助的是个人资料部分

 <profiles>
  <profile> 
    <id>dev</id>
      <activation>
        <activeByDefault>true</activeByDefault>
      </activation>
      <build>
        <filters>
           <filter>src/main/resources/build/dev.properties</filter>
           </filters>
           <resources>
            <resource>
             <filtering>true</filtering>
             <directory>src/main/resources</directory>
             <includes>
              <include>**/*.xml</include>
              <include>*.properties</include>
             </includes>
            </resource>
           </resources>
          </build>
  </profile>
 <profiles>
</project>

您还需要在 src/main/resources 中有一个属性文件，该文件将具有动态值，并且基于在 maven 构建期间传递的 env 参数，它将占用 src/main/resources/build 文件夹中的相应属性文件。
