JSF和Bean验证组

我使用JavaEE7JSF2.2，Bean验证1.1。。。以及WildFly 8.1运行时中的primefaces 5.1

我想根据按下的按钮使用不同的验证组。与少量约束关联的“保存”按钮和与大量约束关联的“提交”按钮

bean验证组似乎正是我所需要的，但我在web界面方面有一些问题

根据验证模式：保存或提交，我不希望无效输入显示为红色

所以我做了3个接口：

public interface LifeCycleValidation {}
public interface Save extends LifeCycleValidation {}
public interface Submit extends Save {}

我在模型对象中使用BeanVal和appropiate组对字段进行注释

@Size(min=3, max = 300, groups = Save.class)
@NotNull(groups = Save.class)
private String title ;

@Size(min = 3, max = 5, groups = Submit.class)
private List<String> keywords ;

并尝试在commandButton的actionListener中设置适当的模式

    <h:form id="bookEditForm">
        <p:messages showDetail="true" showSummary="true"/>
        <p:panelGrid columns="3">

            <p:outputLabel value="title" for="title"/>
            <p:inputText value="#{book.title}" id="title">
                <f:validateBean validationGroups="#{book.validationGroups}"/>
            </p:inputText>
            <p:message showDetail="true" showSummary="true" for="title"/>

            <p:outputLabel value="keywords" for="keywords"/>
            <p:inputText value="#{book.keywords}" id="keywords" converter="converter.ListString">
                <f:validateBean validationGroups="#{book.validationGroups}"/>
            </p:inputText>
            <p:message showDetail="true" showSummary="true" for="keywords"/>

        </p:panelGrid>

        <p:commandButton value="save" action="#{book.save()}" actionListener="#{book.setValidationMode('SAVE')}" update="@form"/>
        <p:commandButton value="submit" action="#{book.submit()}" actionListener="#{book.setValidationMode('SUBMIT')}" update="@form"/>

    </h:form>

但这不起作用

我想写我自己的jsf验证器，但我不知道如何实现验证器来根据正确的组验证字段。我最终发现了一些东西，当onmouseover发生时，我触发setValidationMode，就像在调用action:save或submit之前设置了验证模式一样

        <h:panelGroup layout="span">
            <p:ajax event="mouseover" listener="#{book.setValidationMode('SAVE')}"/>
            <p:commandButton value="save" action="#{book.save()}" update="@form"/>
        </h:panelGroup>            
        <h:panelGroup layout="span">
            <p:ajax event="mouseover" listener="#{book.setValidationMode('SUBMIT')}"/>
            <p:commandButton value="submit" action="#{book.submit()}" update="@form"/>
        </h:panelGroup>

编辑

以下是干净完整的MVC解决方案，progressbar以奖金计算：

观点：

    <h:form id="bookEditForm">

        <p:progressBar value="#{bookBean.progress}" labelTemplate="{value}%" id="progress"/>

        <p:messages showDetail="true" showSummary="true"/>

        <p:panelGrid columns="3">

            <p:outputLabel value="title" for="title"/>
            <p:inputText value="#{bookBean.book.title}" id="title">
                <f:validateBean validationGroups="#{bookBean.validationGroups}"/>
            </p:inputText>
            <p:message showDetail="true" showSummary="true" for="title"/>

            <p:outputLabel value="keywords" for="keywords"/>
            <p:inputText value="#{bookBean.book.keywords}" id="keywords" converter="converter.ListString">
                <f:validateBean validationGroups="#{bookBean.validationGroups}"/>
            </p:inputText>
            <p:message showDetail="true" showSummary="true" for="keywords"/>

        </p:panelGrid>

        <h:panelGroup layout="span">
            <p:ajax event="mouseover" listener="#{bookBean.setValidationMode('SAVE')}"/>
            <p:commandButton value="save" action="#{bookBean.save()}" update="@form"/>
        </h:panelGroup>            
        <h:panelGroup layout="span">
            <p:ajax event="mouseover" listener="#{bookBean.setValidationMode('SUBMIT')}"/>
            <p:commandButton value="submit" action="#{bookBean.submit()}" update="@form"/>
        </h:panelGroup>

    </h:form>

模型：

public class Book implements Serializable {

    @NotNull(groups = Save.class)
    @Size(min=1, max = 140, groups = Save.class)
    private String title ;

    @NotNull(groups = Submit.class)
    @Size(min = 3, max = 5, groups = Submit.class)
    private List<String> keywords ;

    // getters and setters
}

ValidationMode、LifeCycleValidation、Save和Submit与问题中的相同

OmniFaces似乎有一个很好的解决方案：

可能很有趣…

不支持键盘post？尝试在p:commandButton上使用actionListener。actionListener中的setValidationMode不起作用，因为setValidationMode需要更新页面中的所有f:validateBean，这在actionListener和ActionButton之间没有发生，而p:commandButton的onmouseover中的do setValidationMode也不起作用，我不知道为什么。。。
