大家好.

我有班公共汽车

Hello everyone.

I have a problem with convert the object to json. I''m using gson to convert the java object to json string, but i got an error for this. Below is the describe

I have a class Bus

class Bus{
 private int id;
 private Route route;

  //setters and getters
}

class Route{
 private int id;
 private List<Bus> listBus;
 
 //setters and getters
}

当我使用gson将总线对象转换为json时，

When i using gson to convert the bus object to json,

Gson gson = new Gson();
Bus bus = getABus();//get the bus
String json = gson.toJson(bus);

它会产生此错误:
