我正在学习Typescript,并试图在一段时间内多次打印控制台消息.但在我的测试中,这发生了一次,你知道原因吗？

代码如下:

 class Class {
    private msg: string;
    constructor(msg: string) {
        this.msg = msg;
    }
    private printMsg(): void {
        console.log(this.msg);
    };
    public repeatMsg(): void {
        let intervalo = setInterval(this.printMsg(), 2000);
        setTimeout(function() {
            clearInterval(intervalo);
        }, 40000);
    }
}

let test: Class;
test = new Class("Hello");
test.repeatMsg();

我在一个组件中有一个对象，我想将它传递给另一个组件。问题是这个其他组件将在新选项卡中打开。

我试图使用数据服务策略，但是当标签打开时，数据服务对象未定义。

我考虑过使用查询参数并传入 url。但是对象很复杂

我的数据服务：

  @Injectable({providedIn: 'root'})
  export class DataService {

   private anime: Anime;

   constructor() { }

   setAnime(anime: Anime) {
    this.anime = anime;
   }
   getAnime() {
    return this.anime;
   }
 }

在数据服务中设置对象：

goToDetailsByService(anime: Anime) {
   this.dataService.setAnime(anime);
   //this.router.navigateByUrl('/details');
   window.open('/details');
}

通过服务数据获取动漫对象：

ngOnInit(): void {
  console.log(this.dataService.getAnime());
  this.anime = this.dataService.getAnime()

}

通过导航路由器访问详细信息组件时

我需要帮助来改善图表线上显示的点数。使用当前代码，对于 100000 个点，仅在图形中绘制了 20 个点。

var elements = new Array(100000);

for (i = 0; i < elements.length; i++) {
    elements[i] = i;
}

var myChart = echarts.init(document.getElementById('main'));
var option = {
    title: {
        text: 'ECharts entry example'
    },
    tooltip: {},
    legend: {
        data:['Sales']
    },
    xAxis: {
        data: elements
    },
    yAxis: {},
    series: [{
        name: 'Sales',
        type: 'line',
        data: elements
    }]
};
myChart.setOption(option);

Guys I'm using flyway on a spring boot project.

When I start the application the migration scripts are executed correctly.

My migrations are in the folder:

flyway.locations = db / migration / postgresql

The problem occurs when I try to execute some purpose of fyway plugin maven from a configuration file.

Configuration File:

flyway.password=root
flyway.schemas=public
flyway.url=jdbc:postgresql://localhost:5432/film
flyway.locations=db/migration/postgresql 

Running the maven command:

mvn flyway: repair -Flyway.config File = myFlywayConfig.properties

Returns the error:

Failed to execute goal org.flywaydb:flyway-maven-plugin:6.1.0:repair (default-cli) on project demo-hibernate-envers: …
