春季-javax.validation.UnexpectedTypeException：HV000030：找不到以下类型的验证器：java.lang.Integer
作者：互联网
我必须分别从表单中获取paper_name和date_of_birth的输入作为int和date数据类型.
下面是代码：
<li> Number:<input type="text" name="paper_number" ></li>
< li>date of birth: <input type="text" name="date_of_birth"></ li>
我在控制器中有paperNumber和dateOfBirth变量分别为int和Date数据类型.
请帮助我将paper_number和date_of_birth的数据类型分别从字符串更改为int和date.
我在stackoverflow上看到了其他答案,他们也使用了jstl,但我无法弄清楚如何在这里应用它.
控制器代码：
@RequestMapping(value = "/student" , params = "add", method = RequestMethod.POST )
public String postAddStudent(
@RequestParam("date_of_birth" ) Date date,
@RequestParam("paper_number" ) int paperNumber)
下面是EntityClass
public class EntityClass extends BaseEntity {
@Column(name = "DATE_OF_BIRTH", nullable = false)
@NotBlank
@DateTimeFormat(pattern = "dd-mm-yyyy")
private Date dateOfBirth;//TODO
@Column(name = "PAPER_NUMBER")
private short paperNumber;
..
}
下面是日志

解决方法:
希望您在休眠状态下使用验证,
@NotBlank
private Date some;
@NotBlank适用于String类型.没有java.util.Date为空的概念.它可以为null或不为null.使用@NotNull代替,
@NotNull
@DateTimeFormat(pattern = "dd-mm-yyyy")
private Date dateOfBirth;
有关更多详细信息,请参见Balus answer和@NotBlank.
更新资料
HTTP Status 400: The request sent by the client was syntactically incorrect.
对于上述Date类型的错误,请尝试添加@DateTimeFormat批注,并提及您输入的日期格式(例如yyyy-mm-dd).像下面一样
@RequestMapping(value="/fetch" , method=RequestMethod.GET)
public @ResponseBody String fetchResult(@RequestParam("from") @DateTimeFormat(pattern="yyyy-MM-dd") Date fromDate) {
//Content goes here
}
