Vaadin Spring 引导 - 尝试导航到“”时出现异常 - NoSuchBeanDefinitionException
Vaadin Spring Boot - There was an exception while trying to navigate to '' - NoSuchBeanDefinitionException
我正在使用 Vaadin 和 Spring Boot 来构建用作注册表单的 webapp。
我在 Tomcat 中部署 webapp 时遇到问题（但从 Intellij IDE 直接启动时从来没有）。

我的项目基本上由 2 个视图和 1 个后端服务 class 组成，用于与名为“Oktaservice”的远程 API 交互。

通过对这个错误的一些研究，我在 OktaService 构造中添加了注释 @Autowired 和 @Qualifier 但没有改变任何东西。
谢谢！
一个潜在的问题可能与您的 Java 包结构有关。 Spring 默认情况下，Boot 仅在包含 Application class.
的 Java 包（及其子包）中查找注释
如果您的 OktaService 位于包结构的某个位置，则默认情况下不会找到它。例如，如果您在 com.example.myapp.ui 中有 Application，在 com.example.myapp.service 中有 OktaService，那么它将不起作用。如果是这种情况，那么您可以更改包结构或在 @SpringBootApplication 中设置 scanBasePackages 属性 以定义覆盖整个应用程序的位置。

我的项目基本上由 2 个视图和 1 个后端服务 class 组成，用于与名为“Oktaservice”的远程 API 交互。
这是我的主视图的代码，导致在到达根页面时出现问题：
注册查看
@PWA(name = "Project", shortName = "Project", enableInstallPrompt = false)
@Route(value = "")
@PageTitle("Project")
@CssImport("./views/widget-view.css")

private final Checkbox privacy_checkbox = new Checkbox();
private final Checkbox conditions_checkbox = new Checkbox();
public RegisterView(@Autowired @Qualifier("OktaService") OktaService oktaService) { this.oktaService = okta服务； addClassName("注册视图");
///////////// For the country selector /////////////
DefaultSchema schema = oktaService.getSchema();
List<OneOfItem> items = schema.getDefinitions().getCustom().getProperties().getCountry().getOneOf();
HashMap<String, String> countries = new HashMap<>();
List<String> values = new ArrayList<>();
for (OneOfItem item : items) {
String title = item.getTitle();
String constant = item.getJsonMemberConst();
countries.put(title, constant);
values.add(title);
}

我的服务 class :
@Service("OktaService")
@PropertySource(value = {"classpath:application.properties"})
public class OktaService {
private HttpHeaders headers;
private HttpStatus status;
private String oktaApiUrl;
private static final String SCHEMAS_API = "/meta/schemas/user/";

private String oktaApiToken;
@Value("${okta.custom.url}")
private String oktaCustomUrl;
public boolean createUser(CreateUser user) {
rs = new RestClient(oktaTenant);
rs.setApiToken(oktaApiToken);
User userCreated = rs.postCreateUser(user, false);
if (rs.getStatus() != null) {
if (!rs.getStatus().toString().startsWith("4")) {
logger.info("POST:CreateUser success : " + userCreated);
} else {
logger.error("POST:CreateUser Error creating user " + user.getProfile().getLogin());
return false;
}
User userActivated = rs.postActivateUser(userCreated.getId(), true);
if (!rs.getStatus().toString().startsWith("4")) {
logger.info("POST:ActivateUser + sendEmail success : " + userCreated);
} else {
logger.error("POST:CreateUser Error creating user " + user.getProfile().getLogin());
return false;
}
} else {
return false;
}
return true;
}
public DefaultSchema getSchema() {
RestTemplate rest = new RestTemplate();
this.headers = new HttpHeaders();
oktaApiUrl = "https://" + oktaTenant + "/api/v1";
headers.add("Content-Type", "application/json");
headers.add("Accept", "*/*");
headers.add("Authorization", "SSWS " + oktaApiToken);
String url = oktaApiUrl + SCHEMAS_API + "default";
HttpEntity<String> requestEntity = new HttpEntity<String>("", headers);
ResponseEntity<DefaultSchema> responseEntity;
try {
responseEntity = rest.exchange(url, HttpMethod.GET, requestEntity, DefaultSchema.class);
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;
}
通过对这个错误的一些研究，我在 OktaService 构造中添加了注释 @Autowired 和 @Qualifier 但没有改变任何东西。
谢谢！
一个潜在的问题可能与您的 Java 包结构有关。 Spring 默认情况下，Boot 仅在包含 Application class.
如果您的 OktaService 位于包结构的某个位置，则默认情况下不会找到它。例如，如果您在 com.example.myapp.ui 中有 Application，在 com.example.myapp.service 中有 OktaService，那么它将不起作用。如果是这种情况，那么您可以更改包结构或在 @SpringBootApplication 中设置 scanBasePackages 属性 以定义覆盖整个应用程序的位置。
