Question

I am getting this error when i try to run my code. The error :

Exception in thread "main" com.sun.xml.internal.ws.spi.db.DatabindingException: com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions

        } catch (Exception e) {
            e.printStackTrace();
        }

    }

}

Can anyone help me out in fixing these errors.

在接口和实现类中将List更改为ArrayList，则可以解决您的异常
