Question

我正在将JSF和Primefaces与Spring集成，我想用JSF和ManagedBean作为控制器来处理导航但由于某种原因我无法将请求从JSF视图发送到ManagedBean控制器，我收到错误： “方法'POST'不允许”我想这是因为在Spring上下文中我需要指定@PostMapping但我的控制器是ManagedBean我该如何解决这个问题。提前谢谢。

ManagedBean代码：

import javax.annotation.PostConstruct;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;

@ManagedBean
@SessionScoped
public class UserLoginView {

    private String username;

    private String password;

    public UserLoginView() {
    }

    @PostConstruct
    public void init() {
        this.username = "";
        this.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;
    }

    public String login() {
        System.out.println("beans.backing.UserLoginView.login()->username: " + username + ", password: " + password);
        // FacesMessage message = null;
        if (username != null && username.equals("admin") && password != null && password.equals("admin")) {
            // message = new FacesMessage(FacesMessage.SEVERITY_INFO, "Welcome", username);
            // FacesContext.getCurrentInstance().addMessage(null, message);
            System.out.println("log in success");
            return "indexLogged";
        } else {
            System.out.println("ok es por aqui");
            // message = new FacesMessage(FacesMessage.SEVERITY_WARN, "Loggin Error",
            // "Invalid credentials");
            System.out.println("mensaje instanciado correctamente");
            // FacesContext.getCurrentInstance().addMessage(null, message);
            System.out.println("Faces Context obtenido correctamente");
            return "index";
        }
        // PrimeFaces.current().ajax().addCallbackParam("loggedIn", loggedIn);
    }
}

的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
    version="3.1">

faces-config.xml中
