当我从另一个调用接口方法时，Spring Boot（Java）中出现以下错误

Question

嗨，我想为我的项目编写一个soap web服务。所以我创建了一个模型，接口和接口实现类......但是当我从接口调用对象时，项目解复失败了......

我使用WebServicePermitRepository obj = new WebServiceImpl();从实现类创建一个对象...但是在编译时它会产生很大的错误...

错误

谁能帮我

Answer 1

请在下面找到代码段。另外，阅读有关工厂设计模式以了解相同的内容。

@WebService(serviceName = "customsPermit", endpointInterface = "lk.slsi.repository.WebServicePermitRepository")
public class WebServiceImpl implements WebServicePermitRepository {

    private static WebServicePermitRepository obj ;

public static WebServicePermitRepository getWebServiceRepository(){
if (obj==null){
    obj = new WebServiceImpl();
}
return obj;
}
    @Override
    public List<CustomsPermit> getPermitByDate(String dtIssue) {
        return obj.getPermitByDate(dtIssue);
    }
}
