我使用此代码下载文件，但它不起作用

FirefoxProfile profile = new FirefoxProfile();

profile.setPreference("browser.download.dir","D:\\WebDriverDownloads");
profile.setPreference("browser.download.folderList", 2);
profile.setPreference("browser.helperApps.neverAsk.saveToDisk","application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;"); 
profile.setPreference( "browser.download.manager.showWhenStarting",false );
profile.setPreference( "pdfjs.disabled",true );


FirefoxDriver driver = new FirefoxDriver(profile);  //Shows error on this line

driver.get("http://toolsqa.com/automation-practice-form/");

driver.findElement(By.linkText("Test File to Download")).click();

Thread.sleep(5000);

它给了我错误

当我删除时

'轮廓'

形成此FirefoxDriver driver = new FirefoxDriver(profile); 代码，然后代码成功运行，但下载文件窗口未关闭，文件也未下载。

我使用机器人代替这个

Robot object=new Robot();
object.keyPress(KeyEvent.VK_DOWN);
object.keyRelease(KeyEvent.VK_DOWN);         
object.keyPress(KeyEvent.VK_ENTER);
object.keyRelease(KeyEvent.VK_ENTER);

它工作正常。但是为什么我上面的代码不起作用？

我在春季启动时使用 MongoDBRepository，当我在数据库中保存一些对象时，一切正常。但是当我通过 id 找到对象时，spring 不允许这样做。

我尝试将 VehicleRoutingProblemSolution 类型更改为 Object 类型，但是 VehicleRoutingProblemSolution 具有其他对象字段 PickupService 并且它没有默认构造函数。是的，这个类是不可变的......我无法创建默认构造函数，我该怎么办？

import com.fasterxml.jackson.annotation.JsonProperty;
import com.graphhopper.jsprit.core.problem.solution.VehicleRoutingProblemSolution;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;

@Document(collection = "vrp_solutions")
public class VrpSolutionHolder {
    // Specifies the solution id
    @Id
    @JsonProperty("id")
    private String id;

    // Specifies the solution id
    @JsonProperty("solution")
    private VehicleRoutingProblemSolution vehicleRoutingProblemSolution;

    // Created at timestamp in millis
    @JsonProperty("created_at")
    private Long created_at = System.currentTimeMillis();


    public VrpSolutionHolder(String id, VehicleRoutingProblemSolution vehicleRoutingProblemSolution) {
        this.id = id;
        this.vehicleRoutingProblemSolution = vehicleRoutingProblemSolution;
    }

    public String getId() {
        return id;
    } …

我使用下面的代码，但它在句子icount = cmd.ExecuteNonQuery上给出了错误

cn.Open()
str = "SELECT [srno],[caste]FROM [SchoolERP].[dbo].[caste] where (caste ='" + (TextBox1.Text) + "')"
cmd = New SqlCommand(str, cn)
dr1 = cmd.ExecuteReader()

If Not dr1.HasRows Then
    str = "INSERT INTO [SchoolERP].[dbo].[caste]([caste])VALUES('" + TextBox1.Text + "')"
    cmd = New SqlCommand(str, cn)
    icount = cmd.ExecuteNonQuery
    MessageBox.Show(icount)

Else
    MsgBox("Record Exists")
    cn.Dispose()
End If
cn.Close()
