在多租户应用程序中动态添加租户后，带有访问域对象 我正在使用Grails 3.3.18中的每个租户方法开发多租户应用程序。当我动态添加租户时，新的房客模式将成功创建。但是，当我说...

Question

在我的自定义schemahandler（mysqlschemahandler）中，我实现了ResolvesCheManames方法，并且在返回列表中定义的任何模式都可以正确设置并正常工作。仅当我尝试在添加新租户后从动态创建的架构中读取数据时，就会出现问题。 我正在使用Mariadb后端，并为其准备了一个schemahandler，如下所述：

class MySQLSchemaHandler extends DefaultSchemaHandler {

    MySQLSchemaHandler() {
        super("USE `%s`", "CREATE SCHEMA `%s`", "contact_app")
    }

    @Override
    Collection<String> resolveSchemaNames(DataSource dataSource) {
        return ['tenant00']
    }
}

这是注册新租户并为租户创建新架构的代码的片段部分。

    Company save(Company company, Boolean registerTenant = false) {
        company.save(flush: true)
        log.info("company record ${company} was created successfully");

        if(registerTenant) {
            this.registerTenantDatastore(company);
        }

        return company;
    }

    HibernateDatastore registerTenantDatastore(Company company) {
        hibernateDatastore.addTenantForSchema(company.tenantId);
        log.info("tenants=[${company.tenantId}] was added successfully...");
        return hibernateDatastore
    }

我们正在运行一个带有数据库的多租户应用程序。显然可能存在差异。无论如何，在创建新数据库之后，我们既添加了Conection源和听众：

{
    DatabaseConfiguration databaseConfiguration = findDatabaseConfigurationByShortName(shortName)
    hibernateDatastore.connectionSources.addConnectionSource(databaseConfiguration.dataSourceName, databaseConfiguration.configuration)
    addTenantListener(new TenantUserPasswordEncoderListener(getTenantDataStore(databaseConfiguration.dataSourceName)))
}            
                HibernateDatastore getTenantDataStore(String tenantName) {
                    HibernateDatastore tenantDatastore = hibernateDatastore.getDatastoreForConnection(tenantName)
                    log.info("getTenantDataStore($tenantName) == $tenantDatastore")
                    tenantDatastore
                }
                @CompileDynamic
                boolean addTenantListener(AbstractPersistenceEventListener listener) {
                    log.debug("(${listener})")
                    boolean result = false
            
                    getGrailsApplication().mainContext.addApplicationListener(listener)
                    result = true
            
                    log.info("(${listener}) == ${result}")
                    result
                }
        
            DatabaseConfiguration findDatabaseConfigurationByShortName(String shortName) {
                log.trace("findDatabaseConfigurationByShortName(${shortName})")
                DatabaseConfiguration result = new DatabaseConfiguration(dataSourceName: shortName, configuration: configurationByShortName(shortName))
                log.debug("findDatabaseConfigurationByShortName($shortName) .result.url == ${result.configuration.get('url')}")
                result
            }
