无法生成api-doc时@restController实现任何接口-springdoc-openapi-ui

Question

有关我的项目的信息：

• Java11.01
• springdoc-openapi-ui 1.5.2
• Spring芯5.1.2。发布
• Spring引导2.1.0。发布

使用此控制器而不实现此接口，我可以生成此API文档：

@RestController
public class MissionApiImpl implements MissionApi {

  @Override
  @GetMapping("/test")
  public ResponseEntity<Void> test() {
    return new ResponseEntity( HttpStatus.OK );
  }
}

生成的单据：

{"openapi":"3.0.1","info":{"title":"OpenAPI definition","version":"v0"},"servers":
[{"url":"http://localhost:9000/mgb/v6.0.0","description":"Generated server url"}],"paths":{"/test":
{"get":{"tags":["mission-api-impl"],"operationId":"test","responses":{"200":
{"description":"OK"}}}}},"components":{}}

但是通过这个接口：

public interface MissionApi {

  ResponseEntity<Void> test();
}

我有一个错误：

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 0
    at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:1006)
    at org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:890)
    at javax.servlet.http.HttpServlet.service(HttpServlet.java:687)
Caused by: java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 0
    at org.springframework.web.method.HandlerMethod$HandlerMethodParameter.getParameterAnnotations(HandlerMethod.java:430)
    a

知道为什么吗？

我试图迁移此Getter注释到接口等，但仍然是相同的错误。

我也犯了同样的错误

springBootVersion = 2.1.1.RELEASE
springdocVersion = 1.5.9

当我升级到

springBootVersion = 2.1.3.RELEASE

所以，这可能是Spring Boot错误或某些Spring Boot依赖项中的错误
