一个日志包装类(包装了log4j)

import org.apache.log4j.Logger;

public class LoggerPack<T> {

private Logger logger;

public void debug(Object message, Class<T> t){
try{
logger = Logger.getLogger(t.getName());
logger.debug(message);
}catch(Exception ex){
ex.printStackTrace();
}
}

public void info(Object message, Class<T> t){
try{
logger = Logger.getLogger(t.getName());
logger.info(message);
}catch(Exception ex){
ex.printStackTrace();
}
}

public void error(Object message, Class<T> t){
try{
logger = Logger.getLogger(t.getName());
logger.error(message);
}catch(Exception ex){
ex.printStackTrace();
}
}
}

测试类:

public class TestLogger {

public static void main(String[] args) {
// TODO Auto-generated method stub

LoggerPack<TestLogger> lp = new LoggerPack<TestLogger>();

lp.debug("hello world", TestLogger.class);
}

}
