是否可以在两个具有不同名称和scala中略有不同字段的案例类之间进行转换(Is it possible to convert between two case class with different name and slightly different field in scala)

例如,我有案例类

case class foo(timestamp:String, epochSecond: Long)

case class bar(epochSecond: Long, timestamp:String)

是否有可能在这两个类的实例之间进行转换?


for example, I have case classes

case class foo(timestamp:String, epochSecond: Long)

and

case class bar(epochSecond: Long, timestamp:String)

Is it possible to make conversion between the instance of these two classes?

最满意答案

您必须从设置PATH的同一命令行运行程序(当然,在设置路径之后)。

如果您尝试从其他地方运行它,则应设置PATH环境。 控制面板中的变量 - >系统优先(*),然后重新启动命令行/ IDE以使新PATH生效

(*)控制面板 - >系统 - >高级系统设置 - > Windows 7上的环境变量


You will have to run your program from the same command line from where you set the PATH(after setting the path, of course).

If you are trying to run it from some other place, you should set the PATH env. variable in the Control Panel -> System first(*), then restart your command line/IDE to have the new PATH in effect

(*) Control Panel -> System -> Advanced System Settings -> Environment Variables on Windows 7
