弹簧数据为嵌套列表对象查找

Question

I am trying to write a findBy in the spring data where I want All employees where employees first department status is ACTIVE. Is it possible using spring data method name, without using custom query?

something like List findByDepartmentFirstStatusIsActive();

I tried few, but none are working so I guess No!!!

Answer 1

You can use under score character _ in order to separate nested property. For example:

findByDepartment_FirstStatus(Status status);

I assume that you have a property with name firstStatus of type Status in Department class, and obviously a field with name department of type Department in your Employee class (for example!).
