DataSource.groovy错误

Question

我是Grails的新手，我正在尝试从“Grails in Action”一书中学习。我有这个例子要求更改DataSource.groovy文件中的dataSource url，当我这样做时，我收到一个错误。以下是更改和错误。谁能帮我吗？提前谢谢，

前面的：

dataSource {
        dbCreate = "update" // one of 'create', 'create-drop', 'update', 'validate', ''
        url = "jdbc:h2:mem:devDb;MVCC=TRUE;LOCK_TIMEOUT=10000"

变更后：

dataSource {
        dbCreate = "update" // one of 'create', 'create-drop', 'update', 'validate', ''
        url = "jdbc:hsqldb:file:devDB;shutdown=true"

错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManagerPostProcessor': 
    Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: 
    Error creating bean with name 'transactionManager':

您已将H2更改为HSQLDB - 您需要向BuildConfig.groovy添加相应的依赖项：

dependencies {
    runtime 'hsqldb:hsqldb:1.8.0.10'
}

在DataSource.groovy中使用以下驱动程序：

driverClassName = "org.hsqldb.jdbcDriver"
