我应该如何在Angular模块中包含模型类？

我希望能够将它们捆绑到一个模块中(它们将用于其他模块),但是尽管有几个咒语,我仍然会遇到这样的错误：

当我启动我的Angular应用程序(ng服务)时,它编译正常,但在浏览器(Chrome)控制台中我收到错误….

Uncaught Error: Unexpected value 'Accreditation' declared by the module 'ServiceModule'. Please add a @Pipe/@Directive/@Component annotation.

我应该如何将这些类捆绑到一个模块中供其他模块使用？我不介意他们是在我的服务模块中还是在另一个新的’beans’模块中.

给定此模块定义(service.module.ts)：

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import {MemberService} from "./member/member.service";
import { Accreditation } from "./accreditation";
import {Player} from "./player";
import {Club} from "./club";
import {Coach} from "./coach";

@NgModule({
  imports: [CommonModule],declarations: [Accreditation,Club,Player,Coach],exports: [Accreditation,providers: [MemberService]
})
export class ServiceModule { }

accreditation.ts：

export class Accreditation {
    uuid: string;
    name :string;
    lastComplete: Date;
    expires: Date;
    inLast6Months: boolean;
    type: String;
    displayName: String;
    hasCompleted: boolean;
}
