未找到 Roo 的“数据库”命令（对于 DBRE）

【中文标题】未找到 Roo 的“数据库”命令（对于 DBRE）【英文标题】：Roo's 'database' command not found (for DBRE) 【发布时间】：2018-11-02 11:59:56 【问题描述】：

首先，我是 Spring Roo 新手。

当我尝试使用 Roo 的“数据库”命令从我的数据库中对 bean 进行逆向工程时，Roo 找不到该命令：

roo> database
Command 'database' not found (for assistance press CTRL+SPACE or type "hint" then hit ENTER)
Searching 'database' on installed repositories
0 matches found with 'database' on installed repositories

我正在使用：

Spring Roo 2.0.0.RELEASE STS 3.9.4 Spring IDE Roo 支持 3.9.4.201804120850-RELEASE

我想我可能会错过 DBRE 插件。在查找有关该插件的详细信息时，我在 documentation for Spring Roo 2.0.0.M1 中找到了有关它的信息，但在 documentation for Spring Roo 2.0.0.RELEASE 中没有找到。

DBRE 插件是否从 Spring Roo 2.0.0.RELEASE 中排除？回到 2.0.0.M1 似乎不是正确的解决方案。

这里是我的附加组件列表：

感谢您的帮助。

是的，抱歉，Spring Roo 2.0 不包含 DBRE 插件。

此功能需要从头开始重新创建，并且无法在 2.0.0 RELEASE 中包含它

祝你好运。

【讨论】：

感谢您的回复，@jmvivo。 DBRE 插件可以为我节省大量时间。你建议我怎么做？我想我可以手动包含这个附加组件吗？这个具体的命令是什么样的？谢谢。 对不起，它不包括在内，因为它没有迁移到 2.0 版本（正如我在回答中已经说过的，没有办法轻易做到这一点）。如果您需要 DBRE Roo 2.0 不是您的工具。
