Spring数据Mongodb使用@Query处理日期

Question

您能帮助我在Spring Data Mongodb中使用@Query查找使用日期的数据吗？

我在下面提供了我的代码：

存储库类：

public interface CustomerRepository extends MongoRepository<Customer, String> {
    @Query("{ 'createdDateTime' : { $gt: ?0 } }")
    List<Customer> findAllCustomersByCreatedDate(Date date);
}

ServiceImpl类：

@Service("CustomerService")
public class CustomerServiceImpl implements CustomerService {
    public List<Customer> findAllCustomersByCreatedDate(String createdDate) throws ParseException {
        return customerRepository.findAllCustomersByCreatedDate(new SimpleDateFormat("YYYY-MM-DD").parse(createdDate));
    }
}

RestController类：

@RestController
@RequestMapping("customers")
public CustomerController {

    @Autowired
    private CustomerService customerService;

    @RequestMapping(value = "/byCreatedDate", method = RequestMethod.GET, produces = { "application/json;charset=UTF-8" })
    public ResponseEntity<List<Customer>> findAllCustomersByCreatedDate(@RequestParam String createdDate)
            throws BusinessException, ParseException {

        List<Customer> customers = customerService.findAllCustomersByCreatedDate(createdDate);
        return ResponseEntity.status(HttpStatus.OK).body(customers);
    }
}

Mongo数据库内的数据供客户收集：

{ "_id" : ObjectId("57851d1ee59782560e77ac3f"), 
  "_class" : "com.myproject.models.Customer", 
  "name" : "Rob",
  "createdBy" : "John", 
  "createdDateTime" : ISODate("2016-07-12T16:38:54.439Z")
}

{ "_id" : ObjectId("5786222b29b42251b16b5233"), 
  "_class" : "com.myproject.models.Customer", 
  "name" : "Sara",
  "createdBy" : "John", 
  "createdDateTime" : ISODate("2016-07-13T08:38:52.116Z")
}

如果我用日期字符串“2016-07-19T14:38:54.439Z”调用下面的URL，即使数据库中没有2016-07-19之后创建的记录，它仍然会返回2个结果（以上2个文档）。

http://localhost:8080/projects/byCreatedDate?createdDate=2016-07-19T14： 38:54.439Z

我上面的代码有什么问题？你能帮忙吗？

如何更正上面的代码来处理Mongodb的日期？

Answer 1

另一种方式-

DateTimeFormatter dtf = DateTimeFormat.forPattern("yyyy-MM-dd");
LocalDate localDate = dtf.parseLocalDate(createdDate);    
Date dt = Date.from(localDate.atStartOfDay().toInstant(ZoneOffset.UTC));
return customerRepository.findAllCustomersByCreatedDate(dt);

Answer 2

我发现了日期格式不正确的问题，并更改了ServiceImpl类代码，如下所示，现在文档按预期获取：

return customerRepository.findAllCustomersByCreatedDate(
    new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'").parse(createdDate)
);
