我正在使用 spring roo 构建一个简单的应用程序。完成某些工作后，我已经完全删除了 roo。

所以这是我创建新数据的控制器方法..

@RequestMapping(params = "form", produces = "text/html")
public String createForm(Model uiModel) {
    populateEditForm(uiModel, new PatientDetails());
    return "patientdetailses/create";
}

 @RequestMapping(method = RequestMethod.POST, produces = "text/html")
public String create(@Valid PatientDetails patientDetails,
        BindingResult bindingResult, Model uiModel,
        HttpServletRequest httpServletRequest) {

    if (bindingResult.hasErrors()) {
        populateEditForm(uiModel, patientDetails);
        return "patientdetailses/create";
    }
    uiModel.asMap().clear();

    patientDetailsService
            .savePatientDetails(setCurrentUser(patientDetails));
    return "redirect:/patientdetailses/"
            + encodeUrlPathSegment(patientDetails.getId().toString(),
                    httpServletRequest);
}

 void populateEditForm(Model uiModel, PatientDetails patientDetails) {
    uiModel.addAttribute("patientDetails", patientDetails);
    addDateTimeFormatPatterns(uiModel);
    uiModel.addAttribute("sexes", Arrays.asList(Sex.values()));
    uiModel.addAttribute("typeOfPatients",
            typeOfPatientService.findAllTypeOfPatients());
}

我的域名：

 public class PatientDetails {

@NotNull
@NotBlank
@NotEmpty
@Size(max = 40)
private String firstName;

@NotNull
@NotBlank
@NotEmpty
@Size(max = 40)
private String lastName;

@Size(max = 40)
private String middleName;

@Size(max = 200)
@NotNull
@NotBlank
@NotEmpty
private String address;

@NotNull
@NotBlank
@NotEmpty
private String city;

@NotNull
private String province;

@NotNull
@Size(max = 5)
private String postalCode;

@NotNull
@Email
@Size(max = 100)
private String email;

@Size(max = 12)
private String homePhone;

@Size(max = 12)
private String workPhone;

@NotNull
private Sex sex;

@Past
@Temporal(TemporalType.TIMESTAMP)
@DateTimeFormat(style = "M-")
@NotNull
private Date dateOfBirth;

@NotNull
@Size(max = 10)
private String socialSecurityName;

@NotNull
@Size(max = 100)
private String occupation;

@ManyToOne
private TypeOfPatient typeOfPatient;

@ManyToOne
private User users;
   }

我在提交表单时遇到错误 在此处输入图像描述

谁能帮我解决这个问题...

提前致谢。

编辑：

TypeOfPatient 类：

 public class TypeOfPatient {

@NotNull
private String patientTypeName;

@NotNull
@Size(max=1024)
private String decriptions;

@Override
public String toString() {
    return patientTypeName;
}

}

我的转换代码：

  @Autowired
TypeOfPatientService typeOfPatientService;

public Converter<String, TypeOfPatient> getStringToTypeOfPatientConverter() {
    return new Converter<String, TypeOfPatient>() {
        @Override
        public TypeOfPatient convert(String id) {
            return typeOfPatientService.findTypeOfPatient(Long
                    .parseLong(id));
        }
    };
}

您基本上必须提供一个Converter.

编辑：

根据您使用的意见<mvc:annotation-driven conversion-service="applicationConversionService"/>。如果这类似于此类，则下面的代码应该可以工作：

public class ApplicationConversionServiceFactoryBean
    extends FormattingConversionServiceFactoryBean {

  @Autowired
  TypeOfPatientService typeOfPatientService;

  @Override
  protected void installFormatters(FormatterRegistry registry) {
    registry.addConverter(getStringToTypeOfPatientConverter());
    super.installFormatters(registry);
  }

  public Converter<String, TypeOfPatient> getStringToTypeOfPatientConverter() {
    return new Converter<String, TypeOfPatient>() {
      @Override
      public TypeOfPatient convert(String id) {
        return typeOfPatientService.findTypeOfPatient(Long.parseLong(id));
      }
    };
  }
}
