Angular 2材料datepicker更改日期格式不起作用

Question

i有一个Angular 4项目，该项目使用了Angular 2材料datePicker。我已将其中的日期格式更改为DD/mm/yyyy。我已经将代码移至NPM软件包中并发布了它。当我测试包装时，正确的日期格式正在工作，但是当它与另一个项目集成时，材料datePicker选择默认格式(mm/dd/yyyy(。

import {MomentDateAdapter} from '@angular/material-moment-adapter';
import {DateAdapter, MAT_DATE_FORMATS, MAT_DATE_LOCALE} from '@angular/material/core';
import * as _moment from 'moment';
/*Create date format DD/MM/YY */
const moment =  _moment;
export const MY_FORMATS = {
  parse: {
    dateInput: 'D/MM/YYYY'
  },
  display: {
    dateInput: 'DD/MM/YYYY',
    monthYearLabel: 'MMMM Y',
    dateA11yLabel: 'LL',
    monthYearA11yLabel: 'MMMM Y'
  },
};
export class SomeModule {
  static forRoot(): ModuleWithProviders{
    return {
      ngModule: SomeModule ,
      providers: [
        ReportingDashboardService,
        {provide: DateAdapter, useClass: MomentDateAdapter, deps: [MAT_DATE_LOCALE]},
        {provide: MAT_DATE_FORMATS, useValue: MY_FORMATS},
      ]
    }
  }
}

尝试此

import { DateAdapter } from '@angular/material';
constructor(private dateAdapter: DateAdapter<Date>) {
    this.dateAdapter.setLocale('your locale name');
}
