我在密码验证方面遇到了一些问题，@BalusC 帮我解决了，here . 但是在我的表单中插入验证代码之后，当我调用 Controller 方法时，没有任何反应。 这是我的 JSF 页面: 注册.xhtml

<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，没有任何反应，甚至没有任何异常启动。
密码 validator (感谢 BalusC 伙伴):
@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"));
}
}
}
我觉得这个问题很奇怪，我真的不知道这里发生了什么。 谢谢大家。
最佳答案
您在成功匹配时抛出了 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"));
}
这会导致 JSF 阻止表单提交。严重程度无关紧要。 validator 异常是 validator 异常。表示验证失败。
宁可使用FacesContext#addMessage()相反。
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"));
}
关于java - 由于 FacesValidator，ManageBean 方法不再有效？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/7536328/
