Vaadin Spring 引导 - 尝试导航到“”时出现异常 - NoSuchBeanDefinitionException

Question

I'm using Vaadin and Spring Boot to build webapp used as registration form.

I'm getting an issue when deploying the webapp inside a Tomcat (but never when lauching directly from Intellij IDE).

The Stacktrace is:

2021-06-04 09:27:13.289 ERROR  [reportException] com.vaadin.flow.router.InternalServerError:97 : There was an exception while trying to navigate to ''

My project is basically composed of 2 views and 1 backend service class used to interact with a remote API called "Oktaservice".

Here is the code of my main view causing the issue when reaching the root page:

            this.setStatus(responseEntity.getStatusCode());
            return responseEntity.getBody();
        } catch (HttpClientErrorException e) {
            logger.error(e.getStatusCode());
            return null;
        }
    }

    public String getOktaCustomUrl() {
        return oktaCustomUrl;
    }


    public void setStatus(HttpStatus status) {
        this.status = status;
    }

With some research on this error I added the annotation @Autowired and @Qualifier to OktaService construction but did not change anything.

Thank you !

Answer 1

One potential problem could be with your Java package structure. Spring Boot does by default only look for annotated within the Java package (and it's children) that contains the Application class.

If your OktaService is in a location of your package structure, then it won't be found by default. As an example, if you have Application in com.example.myapp.ui and OktaService in com.example.myapp.service , then it won't work. If this is the case, then you can either change your package structure or set the scanBasePackages property in @SpringBootApplication to define a location that covers the entire application.
