Question

我一直在从事jhipster的项目。截至目前，我正努力与rest api来获取currentdate表（约会）的记录。该代码没有错误，但不输出任何东西。（我的表中也有数据）。

`GET / appointmentspending：获取所有待处理状态的约会。

 @param filter the filter of the request
 @return the ResponseEntity with status 200 (OK) and the list of appointments in body
 /
@GetMapping("/searchappointment")
@Timed
public List<Appointment> getAllAppointmentOfToday(@RequestParam(required = false) String filter) {
     //LocalDate localDate = LocalDate.now();
    // System.out.println("localDate");
  log.debug("REST request to get all Appointments with status pending");
          //LocalDate date = '2019-02-06'

    return StreamSupport
            .stream(appointmentRepository.findAll().spliterator(), false)
            .filter(appointment -> appointment.getLastvisited() == LocalDate.now())
            .collect(Collectors.toList());
}`

在Java中，您不能将对象与==进行比较，因为它会比较对象引用，而不是对象的实际值。这类似于比较C和C ++中的两个指针。

为了比较它们的值，请使用对象的equals方法。

所以您的代码现在看起来如下：

@GetMapping("/searchappointment")
@Timed
public List<Appointment> getAllAppointmentOfToday(@RequestParam(required = false) String filter) {
    // LocalDate localDate = LocalDate.now();
    // System.out.println("localDate");
    log.debug("REST request to get all Appointments with status pending");
    // LocalDate date = '2019-02-06'

    return StreamSupport
            .stream(appointmentRepository.findAll().spliterator(), false)
            .filter(appointment -> appointment.getLastvisited().equals(LocalDate.now()))
            .collect(Collectors.toList());
}`

无法在jhipster中获取基于datefield = currentdate的记录
