JSF支持bean未通过H:CommandButton调用，页面刷新



我有一个登录页面，按钮提交我希望调用备用bean方法。单击"提交"按钮时调用@PostConstruct方法，但未调用BAIN BEAN（登录方法）中的方法。没有显示错误消息，并且日志中没有错误。

这是我的login.xhtml页面：

<html xmlns="http://www.w3.org/1999/xhtml" 
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core">
<h:head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <title>Login</title>
</h:head>
<h:body>
    <p />
    <h:form id="login" prependId="false">
        <h:messages globalOnly="true" />
        <h:outputLabel for="username" value="Username" />
        <h:inputText id="username" value="#{user.username}" required="true" />
        <h:message for="username" />
        <br />
        <h:outputLabel for="password" value="Password" />
        <h:inputSecret id="password" value="#{user.password}" required="true" />
        <h:message for="password" />
        <br />
        <h:commandButton value="Sign in" actionListener="#{user.login}" action="#{user.login}" />
    </h:form>
</h:body>
</html>

这是我的背bean：

@ViewScoped
@Named(value = "user")
public class UserController implements Serializable {
    private static final long serialVersionUID = 1L;
    private String username;
    private String password;
    private String originalURL;
    @PostConstruct
    public void init() {
        ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
        originalURL = (String) externalContext.getRequestMap().get(RequestDispatcher.FORWARD_REQUEST_URI);
        if (originalURL != null) {
            String originalQuery = (String) externalContext.getRequestMap().get(RequestDispatcher.FORWARD_QUERY_STRING);
            if (originalQuery != null) {
                originalURL += "?" + originalQuery;
            }
        }
    }
    public void login() throws IOException {
        HttpServletRequest request = WebContext.getRequest();
        try {
            request.login(username, password);
            if (originalURL != null) {
                WebContext.redirect(originalURL);
            } else {
                WebContext.redirect("/index.xhtml");
            }
        } catch (ServletException e) {
            WebContext.addMessage(null, new FacesMessage("Incorrect username or password!"));
        }
    }
public String getUsername() {
    return username;
}
public void setUsername(String username) {
    this.username = username;
}
public String getPassword() {
    return password;
}
public void setPassword(String password) {
    this.password = password;
}
}

我已将登录到跟踪，单击提交按钮后的输出如下：

任何帮助都将不胜感激，因为我现在花了很多时间试图解决这个问题。谢谢

问题是我在Web.xml中的config正在引起误差并阻止beans方法被调用。

我从我的web.xml中删除了以下内容，而背bean方法被调用：

<login-config>
    <auth-method>FORM</auth-method>
    <realm-name>mysqldomain</realm-name>
    <form-login-config>
        <form-login-page>/login.xhtml</form-login-page>
        <form-error-page>/index.xhtml?error=true</form-error-page>
    </form-login-config>
</login-config>
