我已经处理了这个问题几天了,我无法解决它。我需要的工作设置是:两个独立的数据库,一个用于JUnit测试,另一个用于纯应用程序访问。 我一直在使用MySQL作为应用程序部分,因为我需要完全控制和支持,而我正在考虑的其他数据库是Derby或H2,因为速度在这里是必不可少的。
好的,MySQL数据库正常运行,JUnit测试在我运行时取得了100%的成功 那里没有问题。但是,当我尝试使用第二个数据库配置我的项目时, 出现问题。我一直在寻找答案,我在为spring-roo项目添加额外的数据库时找到了以下设置:
我经常遇到的例外是EntityManager尚未注入。我知道这是一个很难处理的信息,但我只是希望之前得到一些意见,比方说,发布整个代码和文件,以便人们可以看到我是否犯了一些愚蠢的错误(在这一点我相信我没有)或者我错过了一些需要进行的其他更改。
我使用的配置是:最新的spring roo,maven和eclipse 4.2.2
以下是我获得异常的堆栈跟踪:
