我想使用搜索框架通过过滤器实现搜索实现:
@GetMapping("find")
public Page<MerchantUserDTO> getAllBySpecification(
@And({
@Spec(path = "name", spec = LikeIgnoreCase.class),
@Spec(path = "login", spec = LikeIgnoreCase.class),
@Spec(path = "email", spec = LikeIgnoreCase.class),
}) Specification<Users> specification,
@SortDefault(sort = "login", direction = Sort.Direction.DESC) Pageable pageable
) {
return merchantUserService.getAllBySpecification(specification, pageable)
.map(g -> MerchantUserDTO.builder()
.id(g.getId())
.login(g.getLogin())
.build()
);
}
@Override
public Page<Users> getAllBySpecification(Specification<Users> specification, Pageable pageable) {
return dao.findAllByTypeIn(specification, pageable, "MerchantUser");
}
存储库:
@Repository
public interface MerchantUserRepository extends JpaRepository<Users, Integer>, JpaSpecificationExecutor<Users> {
Page<Users> findAllByTypeIn(Pageable page, String... types);
Page<Users> findAllByTypeIn(Specification<Users> specification, Pageable pageable, String... types);
}
但是我得到了例外:
Caused by: java.lang.IllegalArgumentException: At least 2 parameter(s) provided but only 1 parameter(s) present in query.
您知道在定义了规范后如何解决此问题?
