我正在使用JSF 2.这是我的控制器。从控制器获取验证消息
package com.acc.validations;
import java.io.Serializable;
import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
@ManagedBean(name="user")
@SessionScoped
public class Controller implements Serializable{
private static final long serialVersionUID = 1L;
String name;
String password;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
private String checkUser(String name,String password) {
if(("admin".equalsIgnoreCase(name)) && ("admin".equalsIgnoreCase(password))){
return "result";
}else{
/*System.out.println("Enter Valid details");*/
FacesMessage msg = new FacesMessage("Authentication Failed.","Authentication Failed");
msg.setSeverity(FacesMessage.SEVERITY_ERROR);
return null;
}
}
public void execute(){
checkUser(name, password);
}
}
这是我的XHTML页面。

<h1>Custom validator in JSF 2.0</h1>
<h:form >
<h:panelGrid columns="3">
User Name:

我的要求是,如果用户输入用户名和密码为“admin”的控制应该重定向到result.xhtml否则它应该在我写在控制器上FacesContext中显示的信息。 这是我result.xhtml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

xmlns:h="http://java.sun.com/jsf/html">
<h:body>
<h1>Custom validator in JSF 2.0</h1>
<h:panelGrid columns="2">
Welcome to User :
<h:outputText value="#{user.name}" />
</h:panelGrid>
</h:body>
</html>
我不能eventhough呈现result.xhtml我输入admin作为用户名和密码,还我没有得到任何消息,而我也进入错误credentials.And我我没有得到任何错误。请您在这方面帮助我,以便按照我的要求工作。
