我已经创建了一个Java项目，并在source文件夹中添加了log4j库和log4j.xml.我已经正确地初始化了它，但是我得到了错误，如log4j:warn No appenders could be for logger（com.restassured.tests.TokenAuthorization）。 log4j:警告请正确初始化log4j系统。 log4j:warn有关详细信息，请参阅http://logging.apache.org/log4j/1.2/faq.html#noconfig。 代码

    package com.restassured.tests;

import java.io.IOException;

import org.apache.log4j.LogManager;
import org.apache.log4j.Logger;
import org.testng.annotations.Test;

import com.restassured.restcalls.RestCalls;
import com.restassured.utils.PayloadConverterToString;
import com.restassured.utils.URL;

import io.restassured.response.Response;

public class tokenAuthorization {

    private static org.apache.log4j.Logger log = LogManager.getLogger(tokenAuthorization.class.getName());

    Response response;

    @Test
    public void getToken() throws IOException {

        log.info("Invoking request of getToken");

        String uri = URL.getResource("/oauth2/token");
        String payload = PayloadConverterToString.generatePayloadString("TokenPayload.txt");
        response = RestCalls.callPost(uri, payload);
        String strResponse = response.getBody().asString();

        log.info("response =" + strResponse);


    }

}
