jpa-spec 灵感来自于Legacy Hibernate Criteria Queries,这个功能在 JAP 出来之后被 Hibernate 废弃了。 但是用起来还是非常简单和高效的。此库构建与 Spring Data JPA 之上并简化了数据库动态查询。 功能 兼容Spring Data JAP 和 JPA 2.1 接口。 Equal/NotEqual/Like/NotLike/In/NotIn 支持多参数, Equal/NotEqual...
接下来,我们可以创建一个Repository接口,该接口继承自JpaRepository,并且可以使用JpaSpecificationExecutor接口来支持Specification查询。例如: importorg.springframework.data.jpa.domain.Specification;importorg.springframework.data.jpa.repository.JpaRepository;importorg.springframework.data.jpa.repository.JpaSpecificationExecut...
