【问题描述】:
实体类共有三个:User、UserProfile、Country
User 是 OneToOne 映射到 UserProfile UserProfile 是 OneToMany 映射到国家/地区
用户.java
@Entity
@Data
class Users{
@Id
private int id;
@Column(nullable = false)
@NotBlank
private String name;
@OneToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "alumnus_detail_id")
private UserProfile userProfile;
}
下面是 UserProfile.java
@Data
@NoArgsConstructor
@AllArgsConstructor
@Getter
@Setter
@Entity
public class UserProfile {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
@Past(message="You may be a time traveler..")
@NotBlank
private Date dob;
@ManyToOne( cascade = { CascadeType.MERGE,
CascadeType.DETACH,CascadeType.REFRESH} )
@JoinColumn(name="country_id")
@NotBlank
private Country country;
}
下面是country.java
@Data
@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
@Entity
@Table(name="country")
public class Country {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private String phonecode;
private String name;
@JsonIgnore
@UpdateTimestamp //hibernate specific feature
private LocalDateTime lastUpdatedDate;
@JsonIgnore
@CreationTimestamp //hibernate specific feature
private LocalDateTime createdDate;
}
现在,当我想使用 spring:bind 显示国家/地区的验证错误时。显示错误
下面是profile-form.jsp
<form:form action="user-process" method="post" modelAttribute="user">
<spring:bind path="name">
<div class="form-group">
<label for="name">Name</label>
<form:input class="form-control ${status.error ? 'is-invalid' : ''}" id="name" path="name"/>
<form:errors path="name" cssClass="invalid-feedback" />
</div>
</spring:bind>
<spring:bind path="userProfile.country">
<div class="form-group">
<label for="country">Country:*</label>
<form:select class="form-control ${status.error ? 'is-invalid' : ''}" id="country" path="userProfile.country.id">
<form:option value="0">Select </form:option>
<form:options items="${countryList}" itemValue="id" itemLabel="name"/>
</form:select>
<form:errors path="userProfile.country" cssClass="invalid-feedback" />
</div>
</spring:bind>
</form>
下面是用户控制器
@RequestMapping("/user-manage")
public String userUpdate(@ModelAttribute(value = "user") Users user , ModelMap mapData){
mapData.addAttribute("countryList",countryService.findAll());
return "profile-form";
}
但是当包括名称验证在内的其他一切都正常工作时,而不是显示没有验证错误的国家/地区
映射时如何显示验证错误?
