我一直在尝试使用 Roo 1.3.1 当前版本设置 DRBE 项目。我还在最新 Eclipse 版本的 STS 最新版本中设置了项目，所有全新安装以避免冲突。然后我通过 Roo shell 设置 JPA、用户、数据库和密码，然后尝试获取数据库模式。Roo 抱怨没有正确的 jdbc 驱动程序并建议下载它。我这样做了，但不幸的是，由于 slf4j-nop 和 slf4j-api 的一些未满足的依赖关系，Roo 无法安装它。
我也尝试单独安装依赖项，但它们都相互之间存在循环依赖关系，因此无法安装 jdbc 驱动程序（至少目前如此）
roo> jpa setup --provider HIBERNATE --database MYSQL
roo> database properties set --key database.url --value jdbc:mysql://localhost:3306/dbdb
roo> database properties set --key database.password --value $$$$
roo> database properties set --key database.username --value uuuu

但它确实没有部署任何东西或解决依赖关系。我处于一个循环中，每次我尝试对数据库进行逆向工程时，它都会要求我安装 jdbc 包。它要求我安装捆绑包。我愿意。它说它已经部署了捆绑包，但它没有。我重试...等等。
如果我启动一个旧的 1.2.5.RELEASE Roo shell，我碰巧已经安装了它，甚至没有要求我在 Roo 上安装任何包（我想我在过去的某个时候已经做过）
我也试过用osgi安装
roo> osgi obr url add --url http://spring-roo-repository.springsource.org/repository.xml
roo> osgi obr start --bundleSymbolicName org.springframework.roo.wrapping.mysql-connector-java
但它引发了我抱怨 MalformedURLException 的异常，因为捆绑名称上没有协议......

我还尝试清理 .m2 文件夹，以防万一 maven 本地 repo 损坏了某些东西的版本……但没有运气。它现在发布了 Roo shell 抱怨并要求发布 1.6.1 的这些 slf4j 库的 1.7.5 版
我在过去的项目中使用 Springsource 和 Roo 来加快我的开发速度，但这并没有让我加快速度......
提前感谢任何愿意阅读本文的人:)
注意：我可以让它工作的唯一方法是从MySQL 的网站手动下载 jdbc 驱动程序，解压缩并通过 osgi 将其推送到 Roo shell。
roo> osgi start --url file:///Users/..../Downloads/mysql-connector-java-5.1.35/mysql-connector-java-5.1.35-bin.jar
是的，我现在可以工作了，但是 Spring 和 Spring Roo 不就是一个可以加快我们的开发周期的框架和工具吗？我是不是搞错了什么？jdbc 连接这么少见吗？
我仍然想知道是否有更好/更简单/自动的方法来做到这一点。
