从java访问scala对象字段

从java访问scala对象的字段时遇到问题

斯卡拉：

object TestObject {
  val field = 5 
}

爪哇：

错误：

[error] JavaTest.java: cannot find symbol
[error] symbol  : variable field
[error] location: class TestObject
[error]     int i = TestObject.field;

---

Scala字段是私有变量，具有相同名称的getter以保持不变性

public class JavaTest
{
  public static void main(String[] args)
  {
    int i = TestObject.field();
  }
}

---

要查看所有公共成员，请使用：

javap-classpath

。例如

javap-classpath-target/scala-2.9.1.final/classes-TestObject

public class JavaTest
{
  public static void main(String[] args)
  {
    int i = TestObject.field();
  }
}
