有人可以帮我解决我在JSF上的新问题。每当我加载我的页面并提交表单时，我都会收到此错误： 这是我的代码：
@ManagedBean
@ApplicationScoped
public class CommandeController extends JSFActions {
final static Logger LOGGER = LoggerFactory.getLogger( CommandeController.class );
@ManagedProperty( value = "#{commandeBean}")
private CommandeBean commandeBean;
@ManagedProperty( value = "#{clientBean}")
private ClientBean clientBean;
@ManagedProperty( value = "#{etablissementBean}")
private EtablissementBean etablissementBean;
@ManagedProperty( value = "#{commandeFacade}")
private ICommandeFacade commandeFacade;
和我的xhtml文件看起来像
<h:outputText value="#{lbl.postRef}" />
<p:selectOneMenu value="#{commandeBean.idPoste}">
<f:selectItem itemLabel="Choisissez le poste" itemValue="-1"/>
<f:selectItems value="#{jFActions.postes.entrySet()}" var="post"
itemValue="#{post.key}" itemLabel="#{post.value}"/>
</p:selectOneMenu>
<h:outputText value="#{lbl.langUse}" />
<p:selectOneMenu value="#{commandeBean.langUtilise}">
<f:selectItem itemLabel="Choisissez la langue" itemValue="-1"/>
<f:selectItem itemValue="ar" itemLabel="Arabe"/>
<f:selectItem itemValue="en" itemLabel="Enlish"/>
<f:selectItem itemValue="fr" itemLabel="Frensh"/>
</p:selectOneMenu>
<h:outputText value="#{lbl.nbJ}" />
<p:inputText id="txtNbrJour" value="#{commandeBean.nbJour}" converterMessage="#{msg.nbrInvalid}" >
<f:convertNumber type="number" integerOnly="true" />
</p:inputText>
<h:outputText value="#{lbl.nbjMax}" />
<p:inputText id="txtNJAut" value="#{etablissementBean.nbJourAutorise}" readonly="true" />

任何帮助??

您正在使用NumberConverter转换对象。请改用自定义转换器。
答案 1 :(得分：0)
在我的情况下，它发生了，因为我正在记录JSON {"":{}}输出，以及系统生成此异常的原因。 JSON在LogDebug方法中像字符串一样对待。
使用vlogDebug("my log {0}",jsonObject)。它现在可以在参数{0}中使用。
