我在密码验证方面遇到了一些问题,@BalusC可以帮助我here
但是,当我在表单中插入验证代码后,当我调用controller方法时,什么也没有发生。
这是我的JSF页面:
Register.xhtml

    </h:head>

    <h:body>
         <h:form id="form">
            <h:panelGrid columns="3" >

                <h:outputLabel for="name"   value="Nome:" />
                <h:inputText   id="name"    value="#{register.person.name}"  >
                    <f:ajax    event="blur" listener="#{register.validateName}" render="m_name" />
                </h:inputText>
                <rich:message  id="m_name"  for="name"  ajaxRendered="false"/>

                // some fields ..

                <h:outputLabel for="password" value="Password" />
                <h:inputSecret id="password" value="#{register.user.password}">
                    <f:validator validatorId="confirmPasswordValidator" />
                    <f:attribute name="confirm" value="#{confirmPassword.submittedValue}" />
                    <f:ajax event="blur" execute="password confirm" render="m_password" />
                </h:inputSecret>
                <rich:message id="m_password" for="password" />

                <h:outputLabel for="confirm" value="Senha (novamente):" />
                <h:inputSecret id="confirm" binding="#{confirmPassword}" >
                    <f:ajax event="blur" execute="password confirm" render="m_password m_confirm" />
                </h:inputSecret>
                <rich:message id="m_confirm" for="confirm" />

                <h:commandButton value="Register" action="#{register.registerPerson}" >
                    <f:ajax execute="@form" render="@form" />
                </h:commandButton>

                <h:outputText value="#{register.recordStatus}" id="out"  />
                <a4j:status>
                    <f:facet name="start">
                        <h:graphicImage name="loader.gif" library="image"/>
                    </f:facet>
                </a4j:status>
        </h:panelGrid>
    </h:form>
    </h:body>
</html>


因此,当我填写表格并尝试注册时,什么也没有发生,甚至没有任何例外。

密码验证器(感谢BalusC伴侣):

@FacesValidator("confirmPasswordValidator")
public class ConfirmPasswordValidator implements Validator {

    @Override
    public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException {
        String password = (String) value;
        String confirm = (String) component.getAttributes().get("confirm");

        if (password == null || confirm == null) {
            return; // Just ignore and let required="true" do its job.
        }

        if (!password.equals(confirm)) {
            throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_ERROR, null, "password not equal"));
        }else{
            throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_INFO, null, "ok"));
        }
    }

}


我认为这个问题很奇怪,我真的不知道这里发生了什么。
多谢你们。

最佳答案

您在成功的比赛中投了ValidatorException

if (!password.equals(confirm)) {
    throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_ERROR, null, "password not equal"));
} else {
    throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_INFO, null, "ok"));
}


这导致JSF阻止表单提交。严重程度无关紧要。验证程序异常是验证程序异常。它指示验证失败。

而是使用FacesContext#addMessage()代替。

if (!password.equals(confirm)) {
    throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_ERROR, null, "password not equal"));
} else {
    context.addMessage(component.getClientId(), new FacesMessage(FacesMessage.SEVERITY_INFO, null, "ok"));
}
