spring - GORMless Grails应用程序无法查找丢失的(和不必要的)transactionManager

Question

当我的Grails 2.1应用试图使一个名为ServiceParamService的Grails服务实例化时，它的启动会随着下面的BeanCreationException而启动。我不奇怪没有找到一位交易经理，但我不明白为什么要寻找一位交易经理。

在调试器中四处寻找，似乎已经确定ServiceParamService是一种称为"TypeSpecifyableTransactionProxyFactoryBean"的东西，从本质上讲，它采用参数target，proxyTargetClass，transactionAttributeSource和transactionManager。

奇怪的是，该服务可以在另一个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，并且具有相同的Config.groovy，BuildConfig.groovy和resources.xml。因此，以某种运气，愚蠢的运气，另一个应用程序解决了这个问题。除了不扔掉新应用程序(并通过删除旧应用程序的90％重新开始)之外，我如何才能弄清楚旧应用程序在做什么，以解决这个虚假的交易管理器要求？和/或自己解决它？

默认情况下，服务是事务性的。加

static transactional = false

到您的服务类，以防止将其包装在事务代理中。
