Log接口的從新封裝

閒來沒事，看見當前的項目的日誌形式有點冗餘，每一個類都須要聲明確實有點繁瑣，

所以從新將logback從新封裝一下，供整個工程共享使用，版本是1.0.9。

代碼以下：

import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;

import org.slf4j.Marker;
import ch.qos.logback.classic.Level;
public final class Logger {

    private static ch.qos.logback.classic.Logger innerLogger;

    private static final String FQCN = Logger.class.getName();

    private static Method innerMethod;

    public static int load(ch.qos.logback.classic.Logger logger) {
        innerLogger = logger;
        try {
            innerMethod = innerLogger.getClass().getDeclaredMethod("filterAndLog_0_Or3Plus", String.class, Marker.class, Level.class, String.class, Object[].class, Throwable.class);
            innerMethod.setAccessible(true);
        } catch (NoSuchMethodException | SecurityException e) {
            innerLogger.error("load failed, Exception:" + e);
            return -1;
        }
        return 0;
    }

    public static void debug(String msg) {
        innerLogMethod(FQCN, null, Level.DEBUG, msg, null, null);
    }

    public static void error(String msg) {
        innerLogMethod(FQCN, null, Level.ERROR, msg, null, null);
    }
    
    public static void info(String msg) {
        innerLogMethod(FQCN, null, Level.INFO, msg, null, null);
    }
    
    public static void warn(String msg) {
        innerLogMethod(FQCN, null, Level.WARN, msg, null, null);
    }
    
    private static void innerLogMethod(String localFQCN, Marker marker, Level level, String msg, Object[] params, Throwable t)
    {
        try {
            innerMethod.invoke(innerLogger, localFQCN, marker, level, msg, params, t);
        } catch (SecurityException | IllegalAccessException | IllegalArgumentException | InvocationTargetException e) {
            innerLogger.error("execute innerMethod failed, Exception:" + e);
        }
    }
}

詳細原理隨後再解釋吧：
