Fluent Validator .Net Core 注入依赖不起作用

Question

我正在尝试验证派生类，并且我还想验证基类。这是代码，我在 EmployeeValidator 构造函数上有以下错误：

没有给出与“PersonValidator.PersonValidator”所需的形参“personRepository”相对应的参数

    public class Person
    {
        public string FullName { get; set; }
        public int IDCard  { get; set; }
    }

    public class Employee : Person
    {
        public string Position { get; set; }
        public int EmployeeRecord { get; set; }

    }

    public class PersonValidator<T> : AbstractValidator<T> where T : Person
    {
        public PersonValidator(IPersonRepository personRepository)
        {
            RuleFor(b => b.FullName).NotNull();

            RuleFor(x => x)
            .Must(x => !personRepository.ExistsIDCard(x.IDCard))
            .WithErrorCode("IDCardAlreadyExist");
        }
    }

    public class EmployeeValidator : PersonValidator<Employee>
    {
        public EmployeeValidator(IEmployeeRepository employeeRepository)
        {
            RuleFor(d => d.Position).NotNull();

            RuleFor(x => x)
            .Must(x => !employeeRepository.ExistsEmployeeRecord(x.EmployeeRecord))
            .WithErrorCode("EmployeeRecordAlreadyExist");
        }
    }

使用 FluentValidation 框架验证 EmployeeValidator 而不为基类（Person）的字段复制规则的适当方法是什么？

Answer 1

您可以调用base 构造函数并将IPersonRepository 传递给它

public class EmployeeValidator : PersonValidator<Employee>
{
    public EmployeeValidator(IEmployeeRepository employeeRepository, IPersonRepository personRepository) 
        : base(personRepository)
    {
        RuleFor(d => d.Position).NotNull();

        RuleFor(x => x)
        .Must(x => !employeeRepository.ExistsEmployeeRecord(x.EmployeeRecord))
        .WithErrorCode("EmployeeRecordAlreadyExist");
    }
}
