Question

我的应用程序在glassfish中运行。我没有看到任何h：message或h：messages（或者，primefaces消息）......有没有配置，我必须在web.xml或faces-config.xml中指定？目前我无法查看是否有任何验证失败，甚至，required =“true”with requiredMessages =“Some Value”不起作用..

<强> JSF

咆哮 - ＆gt; ID = “咆哮”

commandButton - ＆gt;更新= “咆哮”

<?xml version='1.0' encoding='UTF-8' ?>

    </h:head>
    <h:body>
        <h:form>
            <p:growl id="growl" showDetail="false" sticky="true" />  

            <p:commandButton value="Update" update="growl" actionListener="#{userPageBacking.updateUser}"/> 
        </h:form>
    </h:body>
</html>

支持Bean

import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.event.ComponentSystemEvent;

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */
/**

 * @author ezehrt
 */
@ManagedBean
@RequestScoped
public class UserPageBacking {

    public void updateUser() {
        FacesContext fc = FacesContext.getCurrentInstance();

        if (fc.isValidationFailed()) {
            return;
        }


        FacesMessage msg = new FacesMessage("fehlermeldung", "fehlermeldung");

        msg.setSeverity(FacesMessage.SEVERITY_ERROR);

        fc.addMessage("fehlermeldung", msg);

        fc.renderResponse();
    }
}

JSF h：message或p：message不起作用
