Question

我一直在试图解决这个问题，但是它完全使我逃脱了。现在已经搜寻了几天。

关于stackoverflow的大多数答案都指出我不包含slf4j库。资料来源： Getting Exception org.apache.logging.slf4j.SLF4JLoggerContext cannot be cast to org.apache.logging.log4j.core.LoggerContext ClassCastException: org.slf4j.impl.Log4jLoggerAdapter cannot be cast to ch.qos.logback.classic.Logger

但是，堆栈跟踪没有说明这一点。我假设我在LoggerUtil类中做错了什么，并且在主类中使用它时出现了此错误。

不幸的是，我对Web应用程序没有任何控制权（我假设它是使用log4j构建的）。我正在构建一个插件，它用我解析的响应命中了wsdl。我可以在本地运行，没有任何问题，我创建的2个文件可以正常工作。

创建日志文件并追加的logger util类

package com.idmlogic.sigma.plugin;

import ch.qos.logback.classic.Level;
import ch.qos.logback.classic.Logger;
import ch.qos.logback.classic.LoggerContext;
import ch.qos.logback.classic.encoder.PatternLayoutEncoder;
import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.core.FileAppender;
import org.slf4j.LoggerFactory;

import java.util.HashMap;
import java.util.Map;


/**
 * The <code>LoggerUtil</code> creates log file if the file is not created.
 * */
public class LoggerUtil {

    private static Map<String, Logger> loggerMap = new HashMap<>();

    public static Logger createLoggerFor(String name, String file, String info, String pattern) {
        return loggerMap.computeIfAbsent(name, a -> createLogger(a, file, info, pattern));
    }

    private static Logger createLogger(String name, String file, String info, String pattern) {
        Logger logger = (Logger) LoggerFactory.getLogger(name);
        logger.addAppender(getiLoggingEventFileAppender(file, pattern));
        logger.setLevel(Level.valueOf(info));
        logger.setAdditive(false); /* set to true if root should log too */
        return logger;
    }

    private static FileAppender<ILoggingEvent> getiLoggingEventFileAppender(String file, String pattern) {
        FileAppender<ILoggingEvent> fileAppender = new FileAppender<ILoggingEvent>();
        fileAppender.setFile(file);
        LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();
        fileAppender.setEncoder(getPatternLayoutEncoder(lc, pattern));
        fileAppender.setContext(lc);
        fileAppender.start();
        return fileAppender;
    }

    private static PatternLayoutEncoder getPatternLayoutEncoder(LoggerContext lc, String pattern) {
        PatternLayoutEncoder ple = new PatternLayoutEncoder();
        ple.setPattern(pattern);
        ple.setContext(lc);
        ple.start();
        return ple;
    }

}

我使用记录器并假设有休息的主要课堂是以下方法：

private static Logger cprSearchLog;
    private static Properties properties;
    private static Logger errorLog;
/**
     * Init create an errorlog and a cprSearchLog and reads the CprSoeg.request file
     * @param properties contains all attributes required be the module
     * @throws IllegalArgumentException containing a IOException if the CprSoeg.request file was not found
     */
    void init(Properties properties) {
        this.properties = properties;
        errorLog = LoggerUtil.createLoggerFor("errorLog", (String) Objects.requireNonNull(properties.getProperty("ErrorLog"),"ErrorLog can not be null"), properties.getProperty("ErrorLog.Level","INFO"), properties.getProperty("ErrorLog.Pattern","%date %level [%thread] %logger{10} [%file:%line] %msg%n"));
        cprSearchLog = LoggerUtil.createLoggerFor("cprSearchLog", (String) Objects.requireNonNull(properties.getProperty("CPRSearchLog"), "CPRSearchLog can not be null"), properties.getProperty("CPRSearchLog.Level","INFO"), properties.getProperty("CPRSearchLog.Pattern","%date %level [%thread] %logger{10} [%file:%line] %msg%n"));
        try {
            cprSoegRequest = new String(Files.readAllBytes(Paths.get("CprSoeg.request")), Charset.forName("UTF-8"));
        } catch (IOException e) {
            throw new IllegalArgumentException("CprSoeg.request was not found", e);
        }
    }

我还发现JBoss不能与logback一起很好地工作。再一次，我没有权限使用服务器本身。 Logback and Jboss 7 - don't work together?

另一种选择是使用log4j，但也有点困惑。还没有尝试过。任何建议请非常有用。

Java类强制转换例外：org.slf4j.impl.Slf4jLogger无法强制转换为ch.qos.logback.classic.Logger
