用 BTrace 查看 Java 进程，如果方法参数和返回类型是自定义类型怎么办？

譬如下面，参数类型和返回类型是基本类型 int，但是如果是自定义类型怎么办？

@BTrace(unsafe = true)
public class BtraceTest {
@OnMethod(clazz = "Demo", method = "getResult", location = @Location(Kind.RETURN))
public static void getParamAndResultByBtrace(int param1, int param2, @Return int result) {

  System.out.println("===========BTrace begin==================");
  System.out.println("the first param:" + param1);
  System.out.println("the second param:" + param2);
  System.out.println("result: " + result);
  System.out.println("===========BTrace end====================");
  }

}
