如何搜索以开头的字段？

Question

具有过滤功能的Jhipster实体产生api，例如：     http://localhost:8080/api/general-addresses?postalCode.contains=41

which execute sql: ............. postalCode LIKE '%41%'
http://localhost:8080/api/general-addresses?postalCode.contains=
which execute sql: ............. postalCode LIKE '%%'

Is it possible to make request with sql: LIKE '41%'  ?

Answer 1

您可以通过将此值添加为新条件并编写自定义规范来实现。例如，添加条件：

private String postalCodeLike;

请注意，我使用的是String而不是StringFilter。

并添加自定义规范：

if (criteria.getPostalCodeLike() != null) {
      specification = specification.and((root, criteriaQuery, criteriaBuilder) ->
                    criteriaBuilder.like(criteriaBuilder.upper(root.join(FirstRelationedEntity_.fieldName, JoinType.INNER).join(SecondRelationedEntity_.fieldName, JoinType.INNER)
                 .get(Product_.postalCode)),  criteria.getPostalCodeLike().toUpperCase() + "%"));
}
