java - 丰富 :listShuttle error when using complex object

Question

工作中:这是我的工作 rich:listShuttle 当源值和目标值是字符串列表时。

<强>1。 JSF 页面

<rich:listShuttle id="companyJurisdictionShutle"
            sourceValue="#{companyAdminAction.statesList}"
            targetValue="#{companyAdminAction.selectedStates}"
            var="item" orderControlsVisible="false" fastOrderControlsVisible="false"
            sourceCaptionLabel="Available"
            targetCaptionLabel="Selected" styleClass="lishShuttle">
                 <rich:column>
                     #{item}
                 </rich:column>
</rich:listShuttle>

<强>2。支持 bean

//sourceValue                    
public List<String> getStatesList() {

    for (DMPJurisdiction dmpJurisdiction: jurisdictionList) {
        if(!statesList.contains(dmpJurisdiction.getJurisName())) {
            statesList.add(dmpJurisdiction.getJurisName());
        }
    }
    return statesList;
}

//targetValue
public List<String> getSelectedStates() {
    return selectedStates;
}

<强>3。值对象

public class DMPJurisdiction implements Serializable {

    /** serial version UID **/
    private final static Long serialVersionUID = 109892748283726L;

    /** jurisdiction id **/
    private Long jurisId;

    /** name **/
    private String jurisName;

    /** description **/
    private String jurisDescription;

    /** code **/
    private String jurisCode;

    //Getters and Setters

} 

不工作:我更改了列表穿梭，以便 sourceValue 和 targetValue 是复杂对象 (DMPJurisdiction) 的列表，而不是像以前那样的字符串列表。我为此编写了一个转换器。

<强>1。 JSF 页面

<rich:listShuttle id="companyJurisdictionShutle"
      sourceValue="#{companyAdminAction.jurisdictionList}"
      targetValue="#{companyAdminAction.targetJurisdictionList}"
      converter="#{dmpJurisdictionConverter}"
      var="item" orderControlsVisible="false" fastOrderControlsVisible="false"
      sourceCaptionLabel="Available"
      targetCaptionLabel="Selected" styleClass="lishShuttle">
             <rich:column>
                #{item.jurisName}
             </rich:column>
 </rich:listShuttle>

<强>2。支持 Bean:现在返回上面列出的复杂对象 DMPJurisdiction 的列表。

//sourceValue
public List<DMPJurisdiction> getJurisdictionList() {
    return jurisdictionList;
}

//targetValue
    public List<DMPJurisdiction> getTargetJurisdictionList() {
    return targetJurisdictionList;
}

<强>3。转换器

public class DmpJurisdictionConverter implements javax.faces.convert.Converter {

      public Object getAsObject(FacesContext facesContext, UIComponent uiComponent, String s) {
          List<DMPJurisdiction> dmpJurisdictionList = Cache.loadAllDmpJurisdictions();
            for (DMPJurisdiction dmpJurisdiction : dmpJurisdictionList) {
                if (dmpJurisdiction.getJurisName().equals(s)) {
                    return dmpJurisdiction;
                }
            }
            return null;
      }

      public String getAsString(FacesContext facesContext, UIComponent uiComponent, Object o) {
          List<DMPJurisdiction> dmpJurisdictionList = Cache.loadAllDmpJurisdictions();
            for (DMPJurisdiction dmpJurisdiction : dmpJurisdictionList) {
                if (((DMPJurisdiction) o).getJurisName().equals(dmpJurisdiction.getJurisName())) {
                    return dmpJurisdiction.getJurisName();
                }
            }
            return null;
      }

}

<强>4。错误: sourceId=accountWorkcaseOpenTabForm:addDmpCompanySubview:companyJurisdictionShutle[severity=(ERROR 2)，summary=(javax.el.PropertyNotFoundException:/html/workcase/type/dmp/admin/AddCompany.xhtml @55,98 sourceValue="#{companyAdminAction.jurisdictionList}":属性“jurisdictionList”不可写在类型 java.util.List 上)，detail=(javax.el.PropertyNotFoundException:/html/workcase/type/dmp/admin/AddCompany.xhtml @55,98 sourceValue="#{companyAdminAction.jurisdictionList}": 属性“jurisdictionList”在类型 java.util.List 上不可写)] ||||

注意:只是附注，我成功地为 selectOneMenu 使用了相同的 dmpJurisdictionConverter，如下所示，在不同的不相关 JSF 页面中。

<h:selectOneMenu value="#{companyAdminAction.dmpJurisdiction}" converter="#{dmpJurisdictionConverter}">
                    <s:selectItems var="item" value="#{companyAdminAction.jurisdictionList}" label="#{item.jurisName}"
                                   hideNoSelectionLabel="true" noSelectionLabel="-- Select Jurisdiction --"/>
                    <a4j:support event="onchange" action="#{companyAdminAction.loadCompanyList()}"
                             reRender="dmpCompanies"/>
            </h:selectOneMenu>

Answer 1

您可以使用接缝标签“<”s:convertEntity/>

它会自动进行转换，但复杂对象必须是实体
