无法生成api-doc当@RestController实现任何接口- springdoc-openapi-ui

Question

我的项目信息:

• 打开Java 11.01
• springdoc-openapi-ui 1.5.2
• 弹簧芯5.1.2.RELEASE
• 春季启动2.1.0.RELEASE

使用这个控制器而不实现这个接口，我可以生成这个API-doc:

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

生成医生:

{"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":{}}

但是使用这个接口:

public interface MissionApi {
ResponseEntity<Void> test();
}

I Have this error:

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)

Caused by: java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 0
at org.springframework.web.method.HandlerMethod$HandlerMethodParameter.getParameterAnnotations(HandlerMethod.java:430)

知道为什么吗?

我尝试将这个Getter注释迁移到接口等，但仍然是相同的错误。

Answer 1

我也有同样的错误

springBootVersion = 2.1.1.RELEASE
springdocVersion = 1.5.9

当我升级到 时，它就解决了

springBootVersion = 2.1.3.RELEASE

所以这可能是Spring Boot错误或者Spring Boot依赖项中的错误
