我的 Grails 2.1 应用程序在启动时崩溃，当它尝试建立一个名为ServiceParamService. 我对它没有找到事务管理器并不感到惊讶，但我不明白它为什么要寻找一个。
在调试器中四处寻找，看起来它决定了ServiceParamServicea "TypeSpecifyableTransactionProxyFactoryBean"，它本质上接受参数target,proxyTargetClass和。transactionAttributeSourcetransactionManager
奇怪的是，该服务在另一个 Grails 应用程序中实例化得很好，该应用程序也没有定义事务管理器，并且具有相同Config.groovy的BuildConfig.groovy, 和resources.xml. 所以不知何故，运气不好，另一个应用程序解决了这个问题。没有扔掉新应用程序（并通过删除 90% 的旧应用程序重新开始），我如何才能弄清楚旧应用程序正在做什么来绕过这个虚假的事务管理器要求？和/或自己解决？
