public class ShowHello {
public static void main(String[] args) {
ApplicationContext ctx=new FileSystemXmlApplicationContext("config.xml");
}
}
一个最简单的读取配置文件语句都会出错
运行以后如下错误
log4j:WARN No appenders could be found for logger (org.springframework.context.support.FileSystemXmlApplicationContext).
log4j:WARN Please initialize the log4j system properly.
