请求处理失败;嵌套异常是javax.validation.ConstraintViolationException

Question

我遇到了Hibernate验证器的问题，当我点击提交按钮保存我的组件时，其组件的验证注释很少，我正在调整HTTP状态500错误。

这是我的弹簧控制器代码。

         @RequestMapping(value = "/add", method = RequestMethod.POST)
             public String postAdd(@Valid BDMComponent bdmComponent,BindingResult result, Model model) {
                 model.addAttribute("componentAttribute",bdmComponent);
                 if(result.hasErrors()){
                     System.out.println("It has errors");
                     return "components";
                 }
                 componentService.addComponent(bdmComponent);
                 model.addAttribute("listComponents", this.componentService.listOfComponents());
                 model.addAttribute("Success", "Component created Successfully");
              return "components";
             }

这是我的实体代码。

@Table(name="BDM_CYO_COMPONENT")
@Entity
@lombok.Data
public class BDMComponent {

    @Id
    @Column(name = "COMPONENT_ID")
    @GeneratedValue(strategy=GenerationType.AUTO)
    private Long id;

    @NotEmpty(message = "{name.required}")
    @Column(name="COMPONENT_NAME")
    private String componentName;

    @NotNull(message = "User name is required.")
    @NotBlank(message = "User name can't be left blank.")
    @Column(name="COMPONENT_IMAG_URL")
    private String componentImgUrl;
}

这是Hibernate的maven代码和pom.xml

中的javax.validation

                <artifactId>validation-api</artifactId>

            </dependency>
