jsonb – Spring 搜索

Question

我如何运行查询

select * from companies where data->>'inn' like '%12%'

使用org.springframework.data.jpa.domain.Specification？

class CompanySpecification : Specification<Company>{
    override fun toPredicate(root: Root<Company>, query:CriteriaQuery<*>, criteriaBuilder: CriteriaBuilder): Predicate? {
        return criteriaBuilder.like(root.get("data-->inn"), "%12%")
    }
}

我找到了解决方案

class CompanySpecification : Specification<Company> {

    override fun toPredicate(root: Root<Company>, query: CriteriaQuery<*>, builder: CriteriaBuilder): Predicate {
        return builder.like(builder.function("jsonb_extract_path_text", String::class.java, root.get<String>("data"), builder.literal("inn")), "12%")
    }

}
