grails - grails mybatis-plugin验证位置

Question

我从mybatis插件文档中引用:

"When working with MyBatis plugin your "Domain" classes should be located in src/groovy and not in grails-app/domain. This is necessary to avoid conflict with GROM since MyBatis plugin can coexist with existing GORM Domain classes."

所以，当我想在MyBatis插件上使用grails时，应该将验证和约束放在哪里？

Answer 1

您可以在Grails中的任何Groovy类中添加@Validateable批注，然后便可以对其进行验证...该插件当前不检查任何验证错误，因此您必须自己实现该代码。

从Grails官方文档中:

Classes which define the static constraints property and are annotated with @Validateable can be made validateable by the framework

http://grails.org/doc/2.1.0/guide/validation.html#validationNonDomainAndCommandObjectClasses

您甚至可以编写一个自定义的MyBatis拦截器(请参阅https://github.com/fzilic/Grails-MyBatis/blob/master/src/groovy/org/grails/plugins/mybatis/locking/OptimisticLockingInterceptor.groovy)并在创建SqlSession之后注册它。

当前，MyBatis插件不支持在其配置中注册自定义拦截器，但可以将其添加到拦截器链中

def factory = GrailsApplication.mainContext.getBean("sqlSessionFactoryBean_dataSource") 

factory.configuration.interceptorChain.addInterceptor(Interceptor)

将来的版本中可能会添加对此功能的支持。
