我有一个具有多租户设置的 grails 项目，但无法正常工作 项目配置
grailsVersion=5.0.0
grailsGradlePluginVersion=5.0.0
groovyVersion=3.0.7
gormVersion=7.1.0
如果在 BootStrap 中添加了 hibernastore，一切正常
class BootStrap {
HibernateDatastore hibernateDatastore
DatabaseProvisioningService databaseProvisioningService
def init = { servletContext ->
def databaseConfiguration = databaseProvisioningService.findDatabaseConfiguration("dbName")
hibernateDatastore.getConnectionSources().addConnectionSource(databaseConfiguration.dataSourceName, databaseConfiguration.configuration)
}
def destroy = {
}
}
但是如果在用户登录时在运行时调用相同的代码
class AuthenticationController
{
static scope="session"
HibernateDatastore hibernateDatastore
AuthenticationService authenticationService
DatabaseProvisioningService databaseProvisioningService
def index() {}
def login()
{
def loginId = params.get("loginId")
def password = params.get("password")
if (loginId != null && password != null)
{
def user = authenticationService.login(loginId, password)
if(user)
{
session.user = user
session.setAttribute(SessionTenantResolver.ATTRIBUTE, "dbName_" + user.tenant.id)
if(!hibernateDatastore.getConnectionSources().getConnectionSource("dbName_" + user.tenant.id))
{
def databaseConfiguration = databaseProvisioningService.findDatabaseConfiguration("dbName_" + user.tenant.id)
hibernateDatastore.getConnectionSources().addConnectionSource(databaseConfiguration.dataSourceName, databaseConfiguration.configuration)
}
}
}
redirect(controller: "user", action: "index")
}
}
一些方法开始失败时没有实体错误 失败的方法是
User.count()
User.save()
工作方法是
User.findById()
User.findByName()
错误堆栈

注意：在这种情况下正确添加了数据存储，它显示在使用调试模式检查时，但域类功能抛出上述错误
尝试添加代码以在 Bootstrap 类中添加数据存储，一切都开始工作
