Spring framework: If I try to use the same class in two otherclasses, a huge loop of loading starts

@QuestionBody
I am using Spring framework. I have a TestNG dataprovider class that creates and sets up the Selenium Webdriver objects Driver and Wait. I want to use its attributes in two other classes

This is the data provider class


public class DataProviderClass {
public static WebDriver driver;
public static WebDriverWait wait;
public static ArrayList<ArrayList<String>> array;
final static String FILE_PATH = "src/test/resources/250.csv";

@DataProvider(name="standardTestData")
public static Object[][] setUp() throws Exception {

//prepare variables here


//pass the data to the test case
Object[][] setUp = new Object[1][3];
setUp[0][0] = driver;
setUp[0][1] = wait;
setUp[0][2] = array;
//setUp[0][3] = array2;
return setUp;
}

And in the test class I use some custom made methods that I get from another class
In the test class I inject the data provider class and the method class like so:

public class AppTest3 {

public static DataProviderClass appdata;
public static WebDriverCustomMethods w;

public AppTest3 () {
ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");
appdata = (DataProviderClass) context.getBean("data");
w = (WebDriverCustomMethods) context.getBean("wdcm");
}

But the method class doesnt recognise "Driver" and "Wait" objects, so I want to inject the Dataprovider class there as well:

public class WebDriverCustomMethods{

public static DataProviderClass appdata;
public WebDriver driver;
public WebDriverWait wait;

public WebDriverCustomMethods () {
ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");
appdata = (DataProviderClass) context.getBean("data");
}


//close the firefox instance after testing or on error
public void quit() {
driver.quit();
}

And when I start the test class, a huge loop of spring loading happens and It stops working at the end:

//this is only a small part of the console output

I am using Spring framework. I have a TestNG dataprovider class that creates and sets up the Selenium Webdriver objects Driver and Wait. I want to use its attributes in two other classes

I am not at all familiar with Spring, but I have seen this same issue with
other injection frameworks, and the usual solution is not to use direct
injection of the needed classes, but to use producers instead, which then
inject an instance later, when it is first needed. Maybe Spring provides a
similar mechanism.

Liebe Gruesse,
