java - 加载属性文件时出错(插件 :maven-war-plugin:2. 4:war:default-war:package)

Question

我想根据配置文件(dev 或 prod)配置属性文件，但是属性文件的位置未正确构造。我在 SO 上找到了类似问题的答案，但这些答案都没有帮助解决这个问题。

我收到的错误如下:

Error loading property file 'E:\Development\CodeSource\GitHub\myproject\profiles\dev\mongo.properties' (org.apache.maven.plugins:maven-war-plugin:2.4:war:default-war:package)

属性文件的实际位置是:

E:\Development\CodeSource\GitHub\myproject\src\main\resources\profiles\dev\mongo.properties

所以我将资源位置设置如下:

<resources>
    <resource>
        <filtering>true</filtering>
        <directory>src/main/resources</directory>
    </resource>
</resources>

尽管如此，它仍然找不到属性文件。

这是整个 pom 文件:

过滤器文件的路径是 relative to the project root, not to src/main/resources 。因此，您需要像这样配置它:

<filters>
    <filter>src/main/resources/profiles/${build.profile.id}/mongo.properties</filter>
</filters>
