Question

我有一个SpringBoot应用程序。这个类用来在我的本地主机环境中伪造邮件发件人

@Service
@Profile("local")
@Qualifier("emailSender")
public class FackeEmailSender {
private static final Logger logger = LoggerFactory.getLogger(FackeEmailSender.class);

和其他

@Service
@Profile("prod")
public class EmailSender {
    private static final Logger logger = LoggerFactory.getLogger(EmailSender.class);

尽管如此，当我启动该应用程序时。使用此配置文件：

spring.profiles.active=local

我收到此错误

Description:

Parameter 0 of method setEmailSender in com.tdk.jms.EmailQueueListener required a bean of type 'com.tdk.services.EmailSender' that could not be found.


Action:

Consider defining a bean of type 'com.tdk.services.EmailSender' in your configuration.

和

@Component
class EmailQueueListener implements QueueListener {


    private EmailSender emailSender;


    @Autowired
    void setEmailSender(EmailSender emailSender) {
        this.emailSender = emailSender;
    }
..
}

Answer 1

您的EmailSender和FackeEmailSender没有实现任何接口。您可以提取EmailSender接口，然后为两个bean实施该接口

Answer 2

您可以尝试使用

@自动连线私人EmailSender emailSender;

代替在setEmailSender上使用
