Good Morning. Can someone help me please?
I followed this tutorial https://www.knowledgefactory.net/2021/09/spring-boot-webflux-video-streaming.html to create a video streaming app. Inside the resources folder there is a subfolder which has two MP4 files inside.
The problem happens when I hit the getVideo inside the next class:
package net.javaguides.springboot.implementations;
import org.springframework.core.io.Resource;
import org.springframework.core.io.ResourceLoader;
import org.springframework.stereotype.Service;
import reactor.core.publisher.Mono;
#Service
public class StreamingService {
private static final String FORMAT = "classpath:videos/%s.mp4";
private ResourceLoader resourceLoader;
public Mono<Resource> getVideo(String title) {
return Mono.fromSupplier(() -> resourceLoader.getResource(String.format(FORMAT, title)));
}
}
The controller uses a configuration bean which is as follows:
package net.javaguides.springboot.config;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.Resource;
import org.springframework.http.MediaType;
import org.springframework.web.reactive.function.server.RouterFunction;
import org.springframework.web.reactive.function.server.RouterFunctions;
import org.springframework.web.reactive.function.server.ServerRequest;
import org.springframework.web.reactive.function.server.ServerResponse;
import net.javaguides.springboot.implementations.StreamingService;
import reactor.core.publisher.Mono;
#Configuration
public class EndPointConfig {
#Autowired
private StreamingService service;
#Bean
public RouterFunction<ServerResponse> router() {
return RouterFunctions.route().GET("video/{title}", this::videoHandler).build();
}
private Mono<ServerResponse> videoHandler(ServerRequest serverRequest) {
String title = serverRequest.pathVariable("title");
return ServerResponse.ok().contentType(MediaType.valueOf("video/mp4")).body(service.getVideo(title),
Resource.class);
}
}
And Controller endpoint that retrieves video stream is as follows:
#Controller
#AllArgsConstructor
public class VideoController {
private StreamingService streamingService;
#GetMapping(value = "video/{title}", produces = "video/mp4")
#ResponseBody
public Mono<Resource> getVideos(#PathVariable String title, #RequestHeader("Range") String range) {
System.out.println("Range in bytes = " + range);
return streamingService.getVideo(title);
}
#GetMapping("show")
public String show() {
return "video";
}
}
And finally, the application has an html file that has a video tag whose src attribute points to the show method of the controller to display the player as follows:
<!DOCTYPE html>

</html>
After running the application, in the url i type http://localhost:8082/show
From that Url, the video player shows up. When I hit the play button, i get 500 Error saying this:
java.lang.NullPointerException: null
at net.javaguides.springboot.implementations.StreamingService.lambda$0(StreamingService.java:17)
This is third day i tried to spot where is the error with no success.
Can someone tell me where I'm getting things wrong.
I highly thank in advance anybody that will take time to help me.
Regards,
You have a not initialized ResourceLoader.
Change this line of code
private ResourceLoader resourceLoader;
in these ones:
#Autowired
private ResourceLoader resourceLoader;
This will tell Spring Context to inject an instance of ResourceLoader in your attribute.

Hi I'm building a skeleton of a car renting webapp and I'm trying to create a view that shows some details like location name, car name etc.
View code- car-list.html
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.w3.org/1999/xhtml">
<head>
<meta charset="UTF-8">
<title>Vehicle List</title>
<h2 th:text="${location1}">Locations</h2>
<table class="table table-stripped">
<thead>
<td th:text="${vehicle1Name}">Vehicle Name</td>
</tr>
</thead>
<td th:text="${vehicle2Name}">Vehicle Name</td>
</tr>
</table>
</head>
<body>
</body>
</html>
And heres my controller
package com.project.CS4125.controller;
import com.project.CS4125.model.*;
import com.project.CS4125.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.ArrayList;
import java.util.List;
#Controller
#RequestMapping("/car-list")
public class VehicleController {
#GetMapping("/car-list")
public String carList(Model model){
Vehicle VWGolf = new BasicCar();
Vehicle Duster = new SUVDecorator(new BasicCar());
Location limerick= new Location("Limerick");
model.addAttribute("location1", limerick.getLocationName());
model.addAttribute("vehicle1Name", "Volkswagen Golf");
model.addAttribute("vehicle2Name", "Dacia Duster");
return "index";
}
}
My problem is the view comes up completely empty, any help appreciated.
EDIT
Before this page I have a register and login page
index.html (register page
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.w3.org/1999/xhtml">
<head>
<meta charset="UTF-8">

<p>Password <input type="password" name="password"></p>
<button type="submit">Login</button>
</form>
<button>Register Here</button>
</body>
</html>
And heres the controller for these
#Controller
#RequestMapping("/")
public class IndexController {
#Autowired
private UserService userService;
#Autowired
private CustomerFactory userFactory;
#PostMapping("/register")
public String registerUser(#ModelAttribute User user){
User u = userFactory.createUser(user.getName(), user.getPassword());
userService.saveUser(u);
return "login";
}
#GetMapping("/login")
public String login(){
return "login";
}
#PostMapping("/login")
public String loginUser(#ModelAttribute User user){
User authenticatedUser = userService.authenticate(user.getName(), user.getPassword());
System.out.println(authenticatedUser.toString());
return "car-list";
}
}
Even after adding the code from the answer below I'm still getting an empty page, after submitting the login form moving to the car list page its still empty.
I also noticed in the answer the URL is http://localhost:8080/car-list but when I try it its http://localhost:8080/login
I've just tested your code and you have two problems.
The first one is at your:
#Controller
#RequestMapping("/car-list")
public class VehicleController {
#GetMapping("/car-list")
In this GetMapping you're saying that you want to access your template at /car-list/car-list.
The seccond one is with your template name. You're returning "index" when you should return "car-list", at this you're returning the template name.
So, editting your code like this:
#Controller
#RequestMapping("/car-list")
public class VehicleController {
#GetMapping
public String carList(Model model){
model.addAttribute("location1", "Answer");
model.addAttribute("vehicle1Name", "Volkswagen Golf");
model.addAttribute("vehicle2Name", "Dacia Duster");
return "car-list";
}
}
I got:
Template working and returning
I'm learnig how Spring boot + MVC works. I can display a message on the screen, but I can not modifying the style. The js e css file don't map with Spring.

I try to upload file from page using axios and can't get it on my controller.
In fromt-end I use Vue.js with axios, and at the back end Spring MVC Controller. It seems that my controller can`t convert FormData() to MultipartFile in spring. I read a lot of questions but have no answer. here is my code:
<!DOCTYPE html>

#ResponseBody
#PostMapping(value="/single-file", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
public ResponseEntity<?> uploadSingle(
#RequestParam(name="file", required = false) MultipartFile file
) {
System.out.println("uploaded");
System.out.println(file);
return ResponseEntity.ok().build();
}
}
I will be very grateful for the advice.
P.S.
when I use #RequestParam(name="file", required=true) MultipartFile file I get error POST http://localhost:8080/single-file 400 (Bad Request), It looks like spring cannot get MultipartFile file from FormData. At back end I don't get any errors, only MultipartFile file = null
After two days, that I spent to solve my promlem I fount a couple of working projects, compare all files and found, that my problem was in dependencies,
I used dependency:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
And when I change dependency:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
Now it's working exactly how I need.

Hibernate validator doesn't work.
my code run properly but doesn't show any error
I am attaching file structure
following libraries are being used
hibernate version 6.0.2
spring version 5.0.6
The code looks fine. Reading your question, it seems that you might be a little confused between these two:
Hibernate ORM: Implementation of JPA
Hibernate Validator: Implementation of Bean Validation
So, for Bean Validation to work, you need to add Hibernate Validator in classpath. Means simply add it in dependencies of your build.gradle/pom.xml i.e. the build script of your build tool.

there is one solution by removing the initialization on the directions list from the method inscription_fournisseur() on the contact_ bean class, and make it in the default constructor of the organisation_ bean class, in this case it works, but I don't prefer this solution, I prefer the first scenario, please help me.
youre using the wrong namespace <f:ajax> should be <p:ajax>
Instead u should change update to update what you want and set the selected value in a method defined by the listener to change your other selectMenu's data
