Java NonuniqueBeandDefinitionException：没有类型为'；AppProperties'；可用：需要单个匹配bean，但找到3个

我正在尝试从application.properties文件加载api键值，下面是类文件。我无法启动应用程序，因为它无法找到唯一的bean。不知道我错过了什么。有人能帮忙吗

这是我们的AppProperties.java

@Component
@PropertySource("classpath:application.properties")
@ConfigurationProperties(prefix = AppProperties.APP_PROPERTIES_PREFIX)
public class AppProperties {

    public static final String APP_PROPERTIES_PREFIX = "bi";

    private String accessTokenUri;
    private String clientId;
    private String clientSecret;
    private String basicAuth;
    private String apiKey;
    //getters and setters
    }
    

@Component
@PropertySource("classpath:application.properties")
@ConfigurationProperties(prefix = "bi")
public class DiagnosticProperties extends AppProperties {
    private String diagnosisUrl;
//getters and setters 
}

@Component
@PropertySource("classpath:application.properties")
@ConfigurationProperties(prefix = "bi")
public class ObservationProperties extends AppProperties {
    private String observationUrl;
//getters and setters
}

这是我们的DiagnosticProperties.java

@Component
@PropertySource("classpath:application.properties")
@ConfigurationProperties(prefix = AppProperties.APP_PROPERTIES_PREFIX)
public class AppProperties {

    public static final String APP_PROPERTIES_PREFIX = "bi";

    private String accessTokenUri;
    private String clientId;
    private String clientSecret;
    private String basicAuth;
    private String apiKey;
    //getters and setters
    }
    

@Component
@PropertySource("classpath:application.properties")
@ConfigurationProperties(prefix = "bi")
public class DiagnosticProperties extends AppProperties {
    private String diagnosisUrl;
//getters and setters 
}

@Component
@PropertySource("classpath:application.properties")
@ConfigurationProperties(prefix = "bi")
public class ObservationProperties extends AppProperties {
    private String observationUrl;
//getters and setters
}

这是我们的ObservationProperties.java

@Component
@PropertySource("classpath:application.properties")
@ConfigurationProperties(prefix = AppProperties.APP_PROPERTIES_PREFIX)
public class AppProperties {

    public static final String APP_PROPERTIES_PREFIX = "bi";

    private String accessTokenUri;
    private String clientId;
    private String clientSecret;
    private String basicAuth;
    private String apiKey;
    //getters and setters
    }
    

@Component
@PropertySource("classpath:application.properties")
@ConfigurationProperties(prefix = "bi")
public class DiagnosticProperties extends AppProperties {
    private String diagnosisUrl;
//getters and setters 
}

@Component
@PropertySource("classpath:application.properties")
@ConfigurationProperties(prefix = "bi")
public class ObservationProperties extends AppProperties {
    private String observationUrl;
//getters and setters
}

这是我们的DiagnosticServiceImpl.java

@Service
public class DiagnosticServiceImpl implements DiagnosticService {
    private static final Logger LOGGER = 
          LoggerFactory.getLogger(ObservationServiceImpl.class);

    private final WebClient webClient;
    private final DiagnosticProperties diagnosticProperties;

    public DiagnosticServiceImpl(final WebClient webClient,final DiagnosticProperties 
                  diagnosticProperties) {
        this.webClient = webClient;
        this.diagnosticProperties = diagnosticProperties;
    }

    @Override
    public Mono<DiagnosticResponse> getPatientDiagnosticDetails(final String uri) {
        return diagnosticDetails(uri);
    }

@服务
公共类DiagnosticServiceImpl实现DiagnosticsService{

您不应该在

AppProperties

上添加任何注释（这可能是一个抽象类）。从它继承的类只需要

@ConfigurationProperties（前缀=“…”）

和

@组件

，或者也可以使用另一个配置类中的

@EnableConfigurationProperties

启用它们

当您注入时-指定要注入的配置属性-可以像您在示例中那样指定类型，也可以向注入点上的参数添加

@Qualifier（“bean name”）

Spring Boot开箱即用配置

应用程序.properties
