java - Spring Roo 2.0.0.M2 问题 Pizzashop 示例问题 2 - 选项 'class' 对此命令不可用

Question

下载并尝试了新的 2.0.0.M2 版本并运行了 Pizzashop 示例，但出现了此错误

field string --fieldName shopCountry --class ~.domain.PizzaOrderPk
Option 'class' is not available for this command when the focus is set to one class.

来自示例目录的代码，但注释了第一行:

Answer 1

您好，感谢您的报告。

我刚刚在 Spring Roo JIRA 上创建了一个与此问题相关的新问题问题跟踪器用于查看 Spring Roo 发行版上提供的 .roo 脚本。

https://jira.spring.io/browse/ROO-3752

回答您的问题，在 Spring Roo 2.0.0.M2 版本中，字段命令已准备好用于当前实体和 DTO 的 future 实现。根据焦点类、实体或 dto 的类型，某些命令参数将可用或不可用。因此，如果您已经将焦点集中在某个类中，则无法使用 --class 参数指示另一个不同的类，以防止您更改为其他类型并对所选类型使用无效参数。

但是，也许这不是处理该问题的最佳方法，因此我们正在分析这种行为。

作为解决方法，您可以在执行字段命令之前执行以下命令来更改焦点类:

focus --class ~.domain.PizzaOrderPk

希望这有帮助。
