我的Java项目无法读取application.properties文件的config，ConfigurationProperties获得null属性。当我使用代码打印类路径时：
@ComponentScan
@EnableCaching
@SpringBootApplication
@EnableAsync
@EnableScheduling
public class Application {
public static void main(String[] args) {
ClassLoader classLoader = ClassLoader.getSystemClassLoader();
URL[] urls = ((URLClassLoader) classLoader).getURLs();
for (URL url : urls) {
System.out.println("classpath:" + url.getFile());
}
//SpringApplication app = new SpringApplication(Application.class);
//app.addListeners(new ApplicationPidFileWriter("app.pid"));
//app.run(args);
}
}
输出为：

Q1：为什么项目类路径中只有2个项目？
Q2：我将src目录标记为源根，当刷新gradle时，源根目录变为灰色（不是源根）！为什么？我的项目问题在哪里？我正在使用Windows 10 + Intellij Idea 2018 + Gradle 3.2.1。这是我的build.gradle：

像这样指定配置文件的绝对路径：
@PropertySource(value = { "file:c:/application.properties" })
