There is a easy way to do this? 回答1: The usually approach to updating the UI without a complete page refresh is through Grails AJAX calls. However based on the limited information you have provided, I think you would need to implement some sort of polling

问题 Java 8 gives the java.time API. I am using a grails application, I want to use java.time for properties of my domain classes. I need to map for instance the LocalDateTime to the DATE/DATETIME on GORM which is built on top of Hibernate. How can I persist my mappings?

In short, you can not use session scoped
