带有限定符 @Default 的类型的不满意依赖项

问题描述

我在运行 Java 应用程序时收到 WELD-001440 错误。我在 Servlet 类上有一个简单的用户界面。它的主要功能是添加新用户。我正在尝试在另一个类中实现使用 api 进行电子邮件验证。

EmailValidationApiOdjemalec 是我尝试从中发出 API 请求的类。 JPAServlet 是我从中调用 EmailValidationApiOdjemalec 类的类。

这是 EmailValidationApiOdjemalec 类

package si.fri.prpo.sledilnik.storitve.odjemalci;

import si.fri.prpo.sledilnik.entitete.Uporabnik;
import si.fri.prpo.sledilnik.storitve.zrna.UpravljanjePrehodovZrno;

import javax.annotation.postconstruct;
import javax.inject.Inject;
import javax.print.attribute.standard.Media;
import javax.ws.rs.ProcessingException;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.core.GenericType;
import javax.ws.rs.core.MediaType;
import java.net.http.HttpRequest;
import java.util.logging.Logger;

public class EmailValidationApiOdjemalec {

    private Client httpClient;
    private String baseURl = "https://rapidprod-something something";
    private String key = "my personal key";
    private String host = "host";
    private Logger log = Logger.getLogger(EmailValidationApiOdjemalec.class.getName());


    @postconstruct
    private void init() {
        log.info("Inicializacija zrna " + EmailValidationApiOdjemalec.class.getSimpleName());

        httpClient = ClientBuilder.newClient();
    }

    public boolean imaUstrezenEmail(Uporabnik uporabnik) {

        String email = uporabnik.getEmail();

        try {

            httpClient
                    .target(baseURl)
                    .queryParam("text",email)
                    .request(MediaType.APPLICATION_JSON)
                    .header("x-rapid-host","whoisapi-email-verification-v1.p.rapidapi.com")
                    .header("x-rapid-key","my rapid key ")
                    .get();

        } catch (WebApplicationException | ProcessingException e) {
            System.out.println("Exception");
        }


        log.info(httpClient.toString());

        return true;
    }
}

现在这是一个 JPAServlet 类，我尝试从中注入，然后从 EmailValidationApiOdjemalec 类调用方法。

package si.fri.prpo.sledilnik.servleti;

import si.fri.prpo.sledilnik.entitete.Uporabnik;
import si.fri.prpo.sledilnik.storitve.dto.PrehodDto;

@WebServlet("/servlet")
public class JPAServlet extends HttpServlet {


    @Inject
    private UporabnikiZrno uporabnikiZrno;

    @Inject
    private EmailValidationApiOdjemalec emailValidationApiOdjemalec;

    @Override
    protected void doGet(HttpServletRequest req,HttpServletResponse resp) throws servletexception,IOException {

        Logger log = Logger.getLogger(UporabnikiVir.class.getName());

        Uporabnik zan = new Uporabnik();
        zan.setIme("Zan");
        zan.setPriimek("Debevec");
        zan.setProstor(dnevnaSoba);
        zan.setEmail("[e-mail]");
        if (!emailValidationApiOdjemalec.imaUstrezenEmail(zan)) {
            log.info("Uporabnik nima pravega emaila");
        }
        uporabnikiZrno.dodajUporabnika(zan);
}
}

还有一条错误信息：
