angular2 ngOnChanges不适用于多个输入

import { Component, Input, OnChanges, SimpleChanges } from '@angular/core';

@Component({
  selector: 'app-example',
  template: `
    <div>{{ input1 }}</div>
    <div>{{ input2 }}</div>
  `
})
export class ExampleComponent implements OnChanges {
  private _input1: string;
  private _input2: number;

  @Input()
  set input1(value: string) {
    this._input1 = value;
    // 在这里执行input1变化时的逻辑
  }
  get input1(): string {
    return this._input1;
  }

  @Input()
  set input2(value: number) {
    this._input2 = value;
    // 在这里执行input2变化时的逻辑
  }
  get input2(): number {
    return this._input2;
  }

  ngOnChanges(changes: SimpleChanges) {
    // 这里不会被调用，因为ngOnChanges不适用于多个输入属性的情况
  }
}
