将Log4J配置为将日志专门输出到每个类实例的唯一文件

Question

我有一个“SomeClass”类，它有自己的log4j记录器。 在我的程序中，我的Someclass实例很少。 如何将Log4j配置为将日志专门输出到我班级的每个实例的唯一文件。

public class SomeClass {
private static Logger logger = Logger.getLogger(SomeClass.class);

private final String name;  
public SomeClass(String name) throws Exception{
    this.name = name;
}

}

public class MainClass{ 
public static void main(String[] args) throws Exception{
    // logs generated by this instance should only go to a file AAA_YYYYMMDD.log
    SomeClass instance1 = new SomeClass("AAA");  
    // logs generated by this instance should only go to a file BBB_YYYYMMDD.log
    SomeClass instance2 = new SomeClass("BBB");
}

}
