HarmonyOS 鸿蒙Next各feature之间 如何互相调用方法 如何互相拉起页面

HarmonyOS 鸿蒙Next各feature之间 如何互相调用方法 如何互相拉起页面 可以参考下面demo

// ets
import Want from '@ohos.app.ability.Want';
import StartOptions from '@ohos.app.ability.StartOptions';
import { BusinessError } from '@ohos.base';
import common from '@ohos.app.ability.common';
import router from '@ohos.router'
// 导入类
import {JumpDemoClass} from '../../../../../../featureDemo/src/main/ets/pages/featureJumpResult/JumpTestClass'
// 使用命名路由方式 需要import对应页面
const JumpResult = import('../../../../../../featureDemo/src/main/ets/pages/featureJumpResult/JumpResult')

@Entry
@Component
struct hapJump {

  build() {
    Column(){
      Text('跳转1').onClick(()=>{
        console.info(new JumpDemoClass().title)
        router.pushNamedRoute({
          name: 'JumpResult',
          params: {
            data1: 'message',
            data2: {
              data3: [123, 456, 789]
            }
          }
        })
      })
      Text('跳转2').onClick(()=>{
        this.jump()
      })
    }.width(100).height(100).backgroundColor(0x100FF00)

  }

  // 使用UIAbility跳转
  jump(){
    let want: Want = {
      bundleName: 'com.example.mintask003',
      abilityName: 'FeatureDemoAbility'
    };
    let options: StartOptions = {
      displayId: 0
    };

    try {
      let context = getContext(this) as common.UIAbilityContext;
      context.startAbility(want, options, (err: BusinessError) => {
        if (err.code) {
          // 处理业务逻辑错误
          console.error(`startAbility failed, code is ${err.code}, message is ${err.message}`);
          return;
        }
        // 执行正常业务
        console.info('startAbility succeed');
      });
    } catch (err) {
      // 处理入参错误异常
      let code = (err as BusinessError).code;
      let message = (err as BusinessError).message;
      console.error(`startAbility failed, code is ${code}, message is ${message}`);
    }
  }
}
