对 Mule Studio 中的属性应用 maven 筛选器

Question

我有一个骡子工作室项目，我已经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中使用了成功的过滤器，或者使用了解决此问题的替代方法？

Answer 1

如果您在pom中定义配置文件.xml（或者如果您喜欢在settings.xml中）并提及应为您加载具有特定环境所需过滤器属性的构建标记，则可以在运行MVN Package时验证这一点，并在jar内查看以检查属性文件是否已打包。因此，为了帮助您，下面的配置文件部分

 <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>

此外，您需要在 src/main/resources 中拥有一个具有动态值的属性文件，并且根据在 maven 构建期间传递的 env 参数，它将从 src/main/resources/build 文件夹中占用相应的属性文件。
