Question

我刚接触百里香和春天。我有一个对象SolicitudeCreateForm和一个InputValueCommandmentFormImpl列表，该列表还包含一个CommandmentOutputValue列表。

@InputValue(
    tipo="type",
    listaCommandments="valoresEntradaCom",
    listaOffices="valoresEntradaOf"
)
public class SolicitudeCreateForm extends BaseEntityForm<Solicitude> {

    @NotNull
    private SolicitudeType type;

.....

@Valid
    private List<InputValueCommandmentFormImpl> valoresEntradaCom;

.....


@PeriodDate(
    startDate="startDate", 
    endDate="endDate", 
    canBeEquals=true
)
public class InputValueCommandmentFormImpl extends 
    BaseEntityForm<InputValueCommandment> implements IInputValueCommandmentForm {

    /**
     * the InputValueCommandmentCreateForm commandment sub type
     */
    @NotNull
    private CommandmentSubtype commandSubType;

    /**
     * the InputValueCommandmentCreateForm commandment sub type value
     */
    @NotNull
    private CommandmentSubtypeValue commandSubTypeValue;

    /**
     * the OutputValueCommandmentCreateForm commandment sub type value
     */
    @NotNull
    private List<CommandmentOutputValue> commandOutputTypeValue;

......


@Entity
@Table(name="commandments_sub_type_output_values")
public class CommandmentOutputValue extends ComboSolicitude {

    /**
     * CommandmentOutputValue extends ComboSolicitude class.
     * 
     */


    /**
     * the serialVersionUID constant.
     */
    private static final long serialVersionUID = 1L;


    @Column(name="defecto")
    private Long defecto;

    /** 
     * the Commandment sub type value commandment sub type 
     */ 
    @ManyToOne(fetch=FetchType.EAGER)
    @JoinColumn(name="sub_commandment_id", nullable=false, referencedColumnName="id")
    private CommandmentSubtype commandmentSubtype;


    public Long getDefecto() {
        return defecto;
    }

    public void setDefecto(Long defecto) {
        this.defecto = defecto;
    }

    /**
     * @return the commandmentSubtype
     */
    public CommandmentSubtype getCommandmentSubtype() {
        return commandmentSubtype;
    }

    /**
     * @param commandmentSubtype to set
     */
    public void setCommandmentSubtype(CommandmentSubtype commandmentSubtype) {
        this.commandmentSubtype = commandmentSubtype;
    }
}

在我的模板中，我有一个用ajax填充的选择倍数

<div th:id="'valoresSalidaSelector' + ${iterStatus.index+1}" class="col-lg-12"
                th:classappend="${!#lists.isEmpty(#fields.errors('valoresEntradaCom[__${iterStatus.index}__].commandOutputTypeValue')) ? 'has-error' : ''}">
                <label class="control-label">[[#{solicitude.new.input.valores_salida}]]:</label>
                 <select th:id="'valoresSalida'+${iterStatus.index+1}" multiple="multiple" size="20" class="form-control dualListValoresSalida required"
                  th:name="${solicitude.valoresEntradaCom[__${iterStatus.index}__].commandOutputTypeValue}" 
                    th:field="${solicitude.valoresEntradaCom[__${iterStatus.index}__].commandOutputTypeValue}"
                    th:with="subTypesValues=${enums.commandSubtypeOutputValRepo.findValueByCommandmentSubtype(solicitude.valoresEntradaCom[__${iterStatus.index}__].commandSubType)}"
                  >
                  <option th:each="commandOutputTypeValue : ${subTypesValues}" th:value="${commandOutputTypeValue.id}" th:title="${commandOutputTypeValue.name}">
                         [[${commandOutputTypeValue.name}]] 

                  </option>

                </select>
                <th:block th:replace="fragments/field_errors :: errors ('valoresEntradaCom[__${iterStatus.index}__].commandOutputTypeValue')">
             </div>


$.ajax({
                method: "POST",
                url: baseUrl()+"api/solicitudes/getSubCommandmentTypeOutputValues",
                data: {data:valor},
                dataType: "json",
                success: function(json){

                    var $el = $("#valoresSalidaSelector"+id+ " select");
                    $el.empty();

                    for(var i=0; i < json.commandmentSubTypeOutputValues.length; i++){ 

                        if (json.commandmentSubTypeOutputValues[i].defecto == 1){
                            $el.append($("<option></option>")
                                    .attr("value",json.commandmentSubTypeOutputValues[i]).attr("selected", "selected").text(json.commandmentSubTypeOutputValues[i].name));
                        }
                        else{
                            $el.append($("<option></option>")
                                    .attr("value",json.commandmentSubTypeOutputValues[i]).text(json.commandmentSubTypeOutputValues[i].name));
                        }

                    }               

                    $el.bootstrapDualListbox('refresh');


                }
            });

在浏览器中正确显示，但是当o尝试获取select的选定值时，i出现此错误

错误堆栈跟踪：

org.springframework.validation.BeanPropertyBindingResult：1个错误字段上的对象“请求”中的字段错误 'valoresEntradaCom [0] .commandOutputTypeValue'：拒绝的值[[object 宾语]];码 [typeMismatch.solicitude.valoresEntradaCom [0] .commandOutputTypeValue，typeMismatch.solicitude.valoresEntradaCom.commandOutputTypeValue，typeMismatch.valoresEntradaCom [0] .commandOutputTypeValue，typeMismatch.valoresEntradaCom.commandOutputTypeValue，typeMismatch.vallesEntradaCom; 论点 [org.springframework.context.support.DefaultMessageSourceResolvable：码 [solicitude.valoresEntradaCom [0] .commandOutputTypeValue，valoresEntradaCom [0] .commandOutputTypeValue]; 参数[];预设讯息 [valoresEntradaCom [0] .commandOutputTypeValue]];预设讯息 [无法将类型'java.lang.String'的属性值转换为属性所需的类型'java.util.List' 'valoresEntradaCom [0] .commandOutputTypeValue';嵌套异常为 java.lang.IllegalStateException：无法转换类型的值 'java.lang.String'为必需的类型属性的'com.sopra.sgmj.entities.enums.CommandmentOutputValue' 'commandOutputTypeValue [0]'：没有匹配的编辑器或转换找到策略]

我完全迷路了，我不知道该怎么办。任何人都可以帮助我或给我小费吗？

Thymeleaf + spring从多个选择中获取选择的值
