为什么我在运行Whiteable错误时找不到状态= 404

问题描述

您好，很抱歉造成所有麻烦，我一直在关注本教程THIS TUTORIAL

这引起了很多麻烦，我已经修复过pom，maven，甚至还无法“清理并构建”它，我已经尝试了Internet上的东西，一直在搜索。 但是这个问题我无法解决，也不知道。

所以我在运行代码时使用的URL 

http://localhost:8282/flight.xhtml

和

http://localhost:8282/index.html

index.html将重定向到flight.xhtml

这是我的index.html 

<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <title>TEST</title>
        <Meta http-equiv="refresh" content="0; URL=static.flight.xhtml" />
    </head>
</html>

我正在使用netbeans 8.2 RC 这就是我的结构

structure

这是我的控制器

    package com.example.demo.controller;

import com.example.demo.model.Flight;
import com.example.demo.repository.FlightRepository;
import org.springframework.beans.factory.annotation.Autowired;

import javax.faces.view.ViewScoped;
import javax.inject.Named;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import org.springframework.stereotype.Controller;


@Named
@ViewScoped
@Controller
public class FlightController implements Serializable {

    private Flight flight = new Flight();

    private List<Flight> flights = new ArrayList<>();

    @Autowired
    private FlightRepository flightRepository;

    public void fetchAll() {
        flights = flightRepository.findAll();
    }

    public void save() {
        flightRepository.save(flight);
        flight = new Flight();
        flights = flightRepository.findAll();
    }

    public void edit(Flight flight) {
        this.flight = flight;
    }

    public void refresh() {
        flight = new Flight();
    }

    public List<Flight> getFlights() {
        return flights;
    }

    public void setFlights(List<Flight> flights) {
        this.flights = flights;
    }

    public Flight getFlight() {
        return flight;
    }

    public void setFlight(Flight flight) {
        this.flight = flight;
    }
    
}

这是我的主要课程

package com.example.demo;



import com.sun.faces.config.ConfigureListener;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletContextinitializer;
import org.springframework.boot.web.servlet.ServletListenerRegistrationBean;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;

import javax.faces.webapp.FacesServlet;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class,args);
    }

    @Bean
    public ServletRegistrationBean facesServletRegistration() {
        ServletRegistrationBean registration = new ServletRegistrationBean<>(new FacesServlet(),"*.xhtml");
        registration.setLoadOnStartup(1);
        return registration;
    }

    @Bean
    public ServletContextinitializer servletContextinitializer() {
        return servletContext -> {
            servletContext.setinitParameter("com.sun.faces.forceLoadConfiguration",Boolean.TRUE.toString());
            servletContext.setinitParameter("primefaces.THEME","nova-light");
        };
    }

    @Bean
    public ServletListenerRegistrationBean<ConfigureListener> jsfConfigureListener() {
        return new ServletListenerRegistrationBean<>(new ConfigureListener());
    }

}

如果您需要看我的pom
