如何通过从JUnit调用方法从项目中的另一个文件夹中获取文件？

Question

@WebService(name = "ManageSearchDataPortType", targetNamespace = "https://abc/searchData", serviceName = "ManageSearchData", portName = "ManageSearchDataPort", wsdlLocation = "/WEB-INF/wsdl/ManageSearchData.wsdl")
@SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE)
import com.xyz.SearchDataRequest;
import com.xyz.SearchDataResponse;

@XmlSeeAlso({ ObjectFactory.class, com.abc.ObjectFactory.class, com.abc..ObjectFactory.class, com.abc..ObjectFactory.class })
public class ManageSearchDataService {

    @WebResult(name = "searchDataResponse", partName = "searchDataResponse", targetNamespace = "https://abc/searchData")
    @WebMethod(action = "http://example.com/wsdl/ManageABC/2008/10/22#searchData")
    public SearchDataResponse searchData(@WebParam(name = "searchDataRequest", partName = "searchDataRequest", targetNamespace = "https://abc/searchData")
        SearchDataRequest searchDataRequest) {
        ClassLoader loader = ManagePriceLinePortTypeImpl.class.getClassLoader();
        java.io.InputStream stream = loader.getResourceAsStream("logHandling.properties"); // stream as null 
        LoggingFramework.initialise(stream); 
        SearchDataResponse response =new SearchDataResponse();
        response.setErrorCode("OK");
        return response;
    }

     public void test();
     {
     System.out.println("TEST  Method");
     }
    }

在上面的代码片段中，我试图从src位置外部读取属性文件，但由于空流而导致文件未找到异常。

HeaderClass只是普通的调用，它包含getMPLNHeader静态方法。

请有任何人知道如何做到这一点让我知道。

package com.test;
import org.junit.Test;
import org.junit.runner.RunWith;    
import org.mockito.Mock;
import org.mockito.runners.MockitoJUnitRunner;

import com.xyz.SearchDataRequest;
import com.aaa.ManageSearchDataService;

@RunWith(MockitoJUnitRunner.class)
public class JunitTestClass {
    ManageSearchDataService mockObj ;

    @Test
    public void doSomething() {
        SearchDataRequest searchDataRequest= new SearchDataRequest();
        searchDataRequest.setStandardHeader(HeaderClass.getMPLNHeader("ASV"));
        SearchDataResponse respose =mockObj.searchData(searchDataRequest); 
        System.out.println("=== "+respose.getErrorCode());      

    }

    }
