TypeScript Dto类触发accessor-pairs错误：已定义Getter仍提示缺失？

ESLint的accessor-pairs规则要求类中定义的setter必须对应同名的getter（这里的“同名”指访问器的属性名一致，而非方法名带set/get前缀）。你当前的写法把setter命名为setEvent、getter命名为getEvent，规则会将二者判定为两个独立的方法，而非同一属性的读写访问器，因此触发错误。另外，setTransaction完全没有对应的getter，这也是报错的原因之一。

修复后的代码示例 #

import { Shop } from "@post-pricing/library/lib/src/orm/typeorm/entity";
import { parse } from "@post-pricing/library/lib/src/utility/date"

export class ShopTransactionsDto {
    private event;
    private shopInfo: Shop;
    private transaction;

    constructor(){
        this.event = null;
        this.shopInfo = null;
        this.transaction = null;
    }

    set event(event) {
        this.event = event;
    }

    get event() {
        return this.event;
    }

    set shopInfo(shopInfo: Shop){
        this.shopInfo = shopInfo;
    }

    get shopInfo() {
        return this.shopInfo;
    }

    set transaction(transaction) {
        this.transaction = transaction;
    }

    get transaction() {
        return this.transaction;
    }
}

说明 #

修改后每个setter都对应了同名的getter，accessor-pairs规则会正确识别这些成对的访问器，错误即可消除。
