Generally your own code is at the beginning of the classpath. Because of this, one way to do it is to create your own org.slf4j.impl.StaticLoggerBinder class:
package org.slf4j.impl;
import org.slf4j.ILoggerFactory;
import org.slf4j.spi.LoggerFactoryBinder;
/**
* Force tests to use JDK14 for logging.
*/
@SuppressWarnings("UnusedDeclaration")
public class StaticLoggerBinder implements LoggerFactoryBinder {
private static final StaticLoggerBinder SINGLETON = new StaticLoggerBinder();
public static String REQUESTED_API_VERSION = "1.6";
public static final StaticLoggerBinder getSingleton() {
return SINGLETON;
}
private StaticLoggerBinder() {
}
@Override
public ILoggerFactory getLoggerFactory() {
return new JDK14LoggerFactory();
}
@Override
public String getLoggerFactoryClassStr() {
return "org.slf4j.impl.JDK14LoggerFactory";
}
}
