log4j2 日志未记录在日志文件夹下的自动生成的日志文件中

Question

这里我试图将执行期间生成的日志保存在日志文件中我使用 lo4j2.properties 和 Testng 侦听器来保存我的日志，我的 log4j2.properties 如下

log4j2.properties

name=PropertiesConfig
property.filename = logs
appenders = console, file

appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = [%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n

appender.file.type = File
appender.file.name = LOGFILE
appender.file.fileName=${filename}/automationLogs.log
appender.file.layout.type=PatternLayout
appender.file.layout.pattern=[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
appender.file.append=true

loggers=file
logger.file.name=Demo
logger.file.level = debug
logger.file.appenderRefs = file
logger.file.appenderRef.file.ref = LOGFILE

rootLogger.level = debug
rootLogger.appenderRefs = stdout
rootLogger.appenderRef.stdout.ref = STDOUT

TestListeners.java file 文件有以下代码

TestListeners.java

package Listners;

import java.util.List;
import java.util.Map;
import java.util.Map.Entry;

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.testng.ITestContext;
import org.testng.ITestListener;
import org.testng.ITestResult;

import RecallAgreementPojo.RecallAgreementPayload;
import io.restassured.response.Response;
import utils.ConvertJSON;


public class TestListeners implements ITestListener{

    private static Logger logger = LogManager.getLogger(TestListeners.class);
    Response  response = null;  
    public void onTestStart(ITestResult result) {

        logger.info("********* Test started **********" + result.getName());

    }

    public void onTestSuccess(ITestResult result) {
        logger.info("********* Test Success **********");
    }

    public void onTestFailure(ITestResult result) {
        ITestContext context = result.getTestContext();
        response = (Response) context.getAttribute("Response");
        if(response != null)
            logger.error("********* Test Failed **********" + response.prettyPrint());

    }

    public void onTestSkipped(ITestResult result) {

        logger.warn("********* Test Skipped **********" + result.getName());

    }

    public void onTestFailedButWithinSuccessPercentage(ITestResult result) {
//      logger.warn("********* Test passed partially with  **********" + result.SUCCESS_PERCENTAGE_FAILURE);

    }

    public void onStart(ITestContext context) {
        logger.info("=========== onStart :-" + context.getName() + "===============");
    }

    public void onFinish(ITestContext context) {
        logger.info("********* Test Completed **********" + context.getName());
        Map<String,List> newAgreementDetails =  (Map<String, List>) context.getAttribute("AgreementDetails");
        Map<String,RecallAgreementPayload> newAgreementsMap = (Map<String, RecallAgreementPayload>) context.getAttribute("AgreementRequests");
        for(Entry<String, List> entry : newAgreementDetails.entrySet()) {
            logger.info(entry.getKey() + " : " +  entry.getValue());
        }

        for(Entry<String, RecallAgreementPayload> entry : newAgreementsMap.entrySet()) {
            logger.info(entry.getKey() + " : " );
            ConvertJSON.JSONConverter(entry.getValue());
        }
    }

}

但是我得到的是空文件 automationLogs.log

Answer 1

log4j2.properties 中的记录器名为 Demo。

logger.file.name=Demo              <<-- logger name
logger.file.appenderRef.file.ref = LOGFILE    <<-- reference to the appender that will write to file

为了写入文件，您需要提供 LogManager 记录器的名称 (Demo) 以便 LogManager 使用它。 LogManager.getLogger("<logger name>").

附加程序 LOGFILE，记录器 Demo 正在引用，然后会将日志写入文件 automationLogs.log.

换句话说，改变这个：

private static Logger logger = LogManager.getLogger(TestListeners.class);

对此：

private static Logger logger = LogManager.getLogger("Demo");

如果这不是您期望的行为，并且确实对将 TestListeners.class 传递给 LogManager 更感兴趣，那么使用 RollingFile 可能更适合您的需要。

虽然我没有在您的配置上测试以下内容，但我的想法是这样的：

appender.rolling.type = RollingFile
appender.rolling.name = fileLogger
appender.rolling.fileName= ${filename}/automationLogs.log
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern =[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
appender.rolling.policies.type = Policies

并使用根记录器引用它：

rootLogger.appenderRef.rolling.ref = fileLogger

希望这对您有所帮助:)
