如何解决Vaadin Spring Boot - 尝试导航到 '' 时出现异常 - NoSuchBeanDefinitionException
我正在使用 Vaadin 和 Spring Boot 构建用作注册表单的 webapp。
我在 Tomcat 中部署 web 应用程序时遇到问题（但从不直接从 Intellij IDE 启动时）。
堆栈跟踪是：

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

});
}
/*------------------------- design functions below -------------------------------------*/
还有我的服务类：
@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 final Logger logger = LogManager.getLogger(OktaService.class);
private RestClient rs;
@Value("${okta.tenant}")
private String oktaTenant;
@Value("${okta.api.token}")
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 @Autowired 和 @Qualifier 注释，但没有改变任何东西。
谢谢！
解决方法
一个潜在的问题可能是您的 Java 包结构。默认情况下，Spring Boot 只会在包含 Application 类的 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 Application 中有 com.example.myapp.ui 而在 OktaService 中有 com.example.myapp.service，那么它将不起作用。如果是这种情况，那么您可以更改您的包结构或在 scanBasePackages 中设置 @SpringBootApplication 属性以定义一个覆盖整个应用程序的位置。
