Question

我正在尝试为RestController设置单元测试，但是对于post方法，我总是获取状态400而不是201。我看不出有什么问题。其余服务使用curl可以正常工作。另外，传递的JSON与传递给原始服务的JSON相同，但是以某种方式我的单元测试无法正常工作。

我得到的错误：

java.lang.AssertionError: Status 
Expected :201
Actual   :400

RestController中的方法：

  @PostMapping("/timesheets")
    public ResponseEntity<Object> createTimesheetEntry(@RequestBody Timesheet timesheet) {

        Timesheet savedTimesheet = timeRepo.save(timesheet);

        URI location = ServletUriComponentsBuilder.fromCurrentRequest().path("/{id}")
                .buildAndExpand(savedTimesheet.getId()).toUri();

        return ResponseEntity.created(location).build();
    }

在这里，我的单元测试方法createTimeSheet无法正常工作。

所以我找到了解决方法：

我从时间表实体中删除了@JsonDeserialize（使用= SqlTimeDeserializer.class）批注，现在我的单元测试成功了，并且我收到HTTP状态201。我并没有真正了解它，但是现在它可以了。感谢您的帮助和建议，以检查生成的JSON。
