在项目开发中，用到了Material的分页组件，需要对该组件进行汉化。

首先创建自定义汉化类：

import {MatPaginatorIntl} from '@angular/material';export class MatPaginatorIntlCro extends MatPaginatorIntl  {  /** A label for the page size selector. */  itemsPerPageLabel = '每页条数: ';  /** A label for the button that increments the current page. */  nextPageLabel = '下一页';  /** A label for the button that decrements the current page. */  previousPageLabel = '上一页';  /** A label for the button that moves to the first page. */  firstPageLabel = '首页';  /** A label for the button that moves to the last page. */  lastPageLabel = '尾页';  /** A label for the range of items within the current page and the length of the whole list. */  getRangeLabel =  (page: number, pageSize: number, length: number) => {    if (length === 0 || pageSize === 0) {      return '0 od' + length;    }    length = Math.max(length, 0);    const startIndex = page * pageSize;    const endIndex = startIndex < length                      ? Math.min(startIndex + pageSize, length)                      : startIndex + pageSize;    return `第${startIndex + 1}-${endIndex}条, 总共${length}条`;  }}

在app.module.ts中声明该Provider：

providers: [    {provide: MatPaginatorIntl, useClass: MatPaginatorIntlCro }    ]

这样在再使用分页组件时，相关信息将显示中文。
