jsonb–Spring搜索

如何运行查询

从数据->>'inn'如“%12%”的公司中选择*

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

我找到了解决办法

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%")
    }

}

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%")
    }

}
