Question

我有一个登录页面，其中按钮提交我希望调用支持bean方法。单击提交按钮时会调用@PostConstruct方法，但不会调用辅助bean（登录方法）中的方法。不会显示任何错误消息，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>

这是我的支持豆：

@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;
}
}

我已将登录记录到跟踪上，点击提交按钮后的输出如下：

任何帮助都会受到赞赏，因为我现在花了很多时间来解决这个问题。感谢

问题是我在web.xml中的配置导致错误并阻止调用beans方法。

我从web.xml中删除了以下内容，并调用了支持bean方法：

<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>

JSF Backing bean没有通过h：commandButton调用，页面只刷新
