使用 SpringBoot 读取资源文件夹中可用的文件

我将读取 Springboot 应用程序中资源文件夹中可用的文件.我已经使用 ResourceLoader 来做到这一点.但是当我尝试执行我的应用程序时，我收到了 FileNotFoundException.

I am going to read a file available in resources folder in my Springboot application. I have used ResourceLoader to do it. But I get a FileNotFoundException when I try to execute my application.

Error creating bean with name 'demoController': Invocation of init method failed; nested exception is java.io.FileNotFoundException: class path resource [schema.graphql] cannot be resolved to absolute file path because it does not reside in the file system: jar:file:/home/dilan/Projects/demo/target/demo.jar!/BOOT-INF/classes!/schema.graphql

下面是我的代码

 @Autowired
private ResourceLoader resourceLoader;

final Resource fileResource = resourceLoader.getResource("classpath:schema.graphql");
File schemaFile = fileResource.getFile();
TypeDefinitionRegistry definitionRegistry = new SchemaParser().parse(schemaFile);
RuntimeWiring wiring = buildRuntimeWiring();

谁能帮我解决这个问题
