BeanIO 是否需要我提供 setter
Does BeanIO require I provide a setter
BeanIO 似乎要求我为我的字段提供设置器。这是必要的吗？我创建了一个 BeanIO 编写器，我只打算编写文件，并且每个字段都有 getter - 为什么我需要 setter？
如果您的 bean 仅打算 序列化 （即由 BeanWriter 使用），您可以将流声明为 mode="write"。这将导致 BeanIO 查找 getter 而不是 setter。
reference guide 指出：
By default, a stream mapping can be used for both reading input streams and writing output streams, called readwrite mode. Setting mode to read orwrite instead, respectively restricts usage to a BeanReader or a BeanWriter only, but relaxes some validations on the mapping configuration.
When mode is set to read, a bean class does not require getter methods.
When mode is set to write, a bean class may be abstract or an interface, and does not require setter methods.
