Grails – 多个数据源

首先,让我开始,我已经看了很多网站关于在Grails上配置多个数据源的“正确”方法,其中每一个(使用Grails 2.0及更高版本)指向 docs ,但是在做了文档说我得到的之后这个错误： @H_874_1@Error 2014-03-29 15:48:29,219 [localhost-startStop-1] ERROR context.GrailsContextLoader - Error initializing the application: Error creaTing bean with name 'transactionManager_lookup': CAnnot resolve reference to bean 'sessionFactory_lookup' while setTing bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.beanCreationException: Error creaTing bean with name 'sessionFactory_lookup': CAnnot resolve reference to bean 'transactionManager' while setTing bean property 'transactionManager'; nested exception is org.springframework.beans.factory.beanCreationException: Error creaTing bean with name 'transactionManager': CAnnot resolve reference to bean '$priMarytransactionManager' while setTing constructor argument; nested exception is org.springframework.beans.factory.beanCreationException: Error creaTing bean with name '$priMarytransactionManager': CAnnot resolve reference to bean 'sessionFactory' while setTing bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.beanCreationException: Error creaTing bean with name 'sessionFactory': CAnnot resolve reference to bean 'transactionManager' while setTing bean property 'transactionManager'; nested exception is org.springframework.beans.factory.beanCurrentlyInCreationException: Error creaTing bean with name 'transactionManager': @R_874_10613@ested bean is currently in creation: Is there an unresolvable circular reference? message: Error creaTing bean with name 'transactionManager_lookup': CAnnot resolve reference to bean 'sessionFactory_lookup' while setTing bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.beanCreationException: Error creaTing bean with name 'sessionFactory_lookup': CAnnot resolve reference to bean 'transactionManager' while setTing bean property 'transactionManager'; nested exception is org.springframework.beans.factory.beanCreationException: Error creaTing bean with name 'transactionManager': CAnnot resolve reference to bean '$priMarytransactionManager' while setTing constructor argument; nested exception is org.springframework.beans.factory.beanCreationException: Error creaTing bean with name '$priMarytransactionManager': CAnnot resolve reference to bean 'sessionFactory' while setTing bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.beanCreationException: Error creaTing bean with name 'sessionFactory': CAnnot resolve reference to bean 'transactionManager' while setTing bean property 'transactionManager'; nested exception is org.springframework.beans.factory.beanCurrentlyInCreationException: Error creaTing bean with name 'transactionManager': @R_874_10613@ested bean is currently in creation: Is there an unresolvable circular reference?

我觉得最有趣的是,如果我指定：

@H_874_1@data@R_696_9016@e_lookup

我会得到：

@H_874_1@Error initializing the application: Error creaTing bean with name 'transactionManager_lookup'

如果我将其更改为：

@H_874_1@data@R_696_9016@e_MysqLdb

我明白了：

@H_874_1@Error initializing the application: Error creaTing bean with name 'transactionManager_MysqLdb'

如果我没有指定第二个数据源,一切正常.

我的代码：

@H_874_1@data@R_696_9016@e { logsql = true pooled = true dialect = org.hibernate.dialect.MysqLInnoDBDialect driverClassname = 'com.Mysql.jdbc.Driver' username = 'myuser' password = 'mypass' url = 'jdbc:MysqL://localhost/mydatabase' dbCreate = 'update' } data@R_696_9016@e_MysqL { dialect = org.hibernate.dialect.MysqLInnoDBDialect driverClassname = 'com.Mysql.jdbc.Driver' username = 'myuser' password = 'mypass' url = 'jdbc:MysqL://localhost/mydatabase' dbCreate = 'update' } data@R_696_9016@e_Oracle { dialect = org.hibernate.dialect.Oracle10gDialect driverClassname = 'Oracle.jdbc.driver.OracleDriver' username = 'myuser' password = 'mypass' url = 'jdbc:Oracle:thin:@localhost:1521:mydatabase' dbCreate = 'update' }

我在这做错了什么？ (如前所述,如果我消除了两个辅助data@R_696_9016@es(data@R_696_9016@e_MysqL和data@R_696_9016@e_OraclE),一切正常).

提前致谢.
