Java Seleniun Hashmap（字符串，WebElement）在传递字符串时不返回WebElement

我编写了一个java类（CustomerHistoryMapping），它包含一个HashMap（String，WebElement），如下所示（代码的第一部分） 我的总体目标是能够使用给定的WebElement，具体取决于传递给HashMap类的字符串

package com.xxxxx.data;

import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import java.util.HashMap;
import java.util.Map;

public class CustomerHistoryMapping {

  @FindBy(xpath = "(//td/span[text()='Preferred Name']/../following-sibling::td[3]/span/span)[1]")
  public WebElement txaNewPreferredNameValue;

  @FindBy(xpath = "(//td/span[text()='Mobile']/../following-sibling::td[3]/span/span)[1]")
  public WebElement txaNewMobileValue;

  @FindBy(xpath = "(//td/span[text()='Email']/../following-sibling::td[3]/span/span)[1]")
  public WebElement txaNewEmailValue;

  @FindBy(xpath = "(//td/span[text()='Mailing Street']/../following-sibling::td[3]/span/span)[1]")
  public WebElement txaNewMailingStreetValue;

  @FindBy(xpath = "(//td/span[text()='Mailing City']/../following-sibling::td[3]/span/span)[1]")
  public WebElement txaNewMailingCityValue;

  @FindBy(xpath = "(//td/span[text()='Mailing Zip/Postal Code']/../following-sibling::td[3]/span/span)[1]")
  public WebElement txaNewMailingPostCodeValue;

  @FindBy(xpath = "(//td/span[text()='Mailing State/Province']/../following-sibling::td[3]/span/span)[1]")
  public WebElement txaNewMailingStateValue;

   Map<String, WebElement> mapping = new HashMap<String, WebElement>();

  public CustomerHistoryMapping() {
    mapping.put("preferredName", txaNewPreferredNameValue);
    mapping.put("mobile", txaNewMobileValue);
    mapping.put("email", txaNewEmailValue);
    mapping.put("address", txaNewMailingStreetValue);
    mapping.put("city", txaNewMailingCityValue);
    mapping.put("postcode", txaNewMailingPostCodeValue);
    mapping.put("state",txaNewMailingStateValue);
  }

  public WebElement getValue(String mapKey) {
    return mapping.get(mapKey);
  }

}

所以HashMap中的WebElement并没有被撤回——知道为什么吗

您应该添加

PageFactory.initElements（…）

，以便使用页面上的元素初始化字段。可以将其添加为构造函数的最后一行

除非您使用了

initelements

，否则所有字段都将引用

null

      objCustomerHistoryMapping = new CustomerHistoryMapping();
      WebElement ele = objCustomerHistoryMapping.getValue("preferredName");
      logger.info("Str is: preferredName, And ele is: " + ele);
