Repeatedly getting WhiteLabel error page w/ Mapping specification - java

I'm new to Spring. I am currently following a tutorial to the T and ran into the "Whitelabel error page". I've done my research, checking Spring boot - Whitelabel Error Page and Spring Boot Remove Whitelabel Error Page with no luck.
I am trying to reach the page by simply using : http://localhost:8080/hello
Obviously Spring cannot find the page, but I cannot figure out why that is.

Any help is appreciated
EDIT:
answer I was looking is found here - Issue With Spring: There was an unexpected error (type=Not Found, status=404)
Add component scanning for packages that are not in the same package, or in sub-packages, of the main class.


you have to configure viewResolver and internalResourceView Resolvers to serve jsp/html files find the below code snippet go through the link
package com.howtodoinjava.app.controller;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ViewResolverRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;
#Configuration
#EnableWebMvc
#ComponentScan
public class MvcConfiguration extends WebMvcConfigurerAdapter
{
#Override
public void configureViewResolvers(ViewResolverRegistry registry) {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/view/");
resolver.setSuffix(".jsp");
resolver.setViewClass(JstlView.class);
registry.viewResolver(resolver);
}
}

How to fix 404 Error when deploying SpringBoot App to AWS Elastic Beanstalk?

I'm trying to deploy a very basic Spring Boot web app to AWS Elastic Beanstalk, It works fine locally, but each time I try to run it on elastic beanstalk I get a 404 error.
Here is my Controller:
package com.example.springhelloworld;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
#Controller
public class HelloWorldController {
#RequestMapping("/")
public String returnHello(){
return "helloworld";
}
}
Here is my main class:
package com.example.springhelloworld;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
#SpringBootApplication
public class SpringHelloWorldApplication extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(SpringHelloWorldApplication.class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(SpringHelloWorldApplication.class);
}
}
Here is my html template:

Unable to configure a simple Controller in Spring boot project

I see two issues.
You need to add this dependency to your pom file
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
/src/main/resources/static is meant to hold static files such as html and css
Create directory src/webapp/WEB-INF/jsp
Move your jsp into the above directory
Update prefix spring.mvc.view.prefix=/WEB-INF/jsp/
https://hellokoding.com/spring-boot-hello-world-example-with-jsp/

Put samples.jsp in "resources/templates"

You muste enable the mvc configuration. Create a class config :
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
#EnableWebMvc
#Configuration
public class Config {
}

How to read jsp file with spring boot?

I'm trying to read my jsp file using spring-boot so i start the project and when i check my localhost it actually return the actual string "index" but not reading it as index.jsp (as jsp file)
I've created Controller Class "HomeController" and implement a method named homePage which will have #RequestMapping then it will return "index"
HomeController
#RestController
public class HomeController {
#RequestMapping("/showHome")
public String homePage(){
return "index";
}
}
index.jsp file
<!DOCTYPE html>
<%# taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<html lang="en">

spring.mvc.view.suffix=.jsp
project stucture
I've got "index" string in my browser was excpecting the jsp file to load
NB: when i replace #ResController with #Controller i get Whitelabel Error Page.

Remove this two line from application.properties file
spring.mvc.view.prefix=/WEB-INF/views/
spring.mvc.view.suffix=.jsp
and Delete templates folder from resource package.
Then add this class in your com.example.demo package.
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.ViewResolverRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
#Configuration
#EnableWebMvc
#ComponentScan(basePackages= {"com.example"})
public class WebConfig implements WebMvcConfigurer {
public void configureViewResolvers(ViewResolverRegistry registry) {
registry.jsp().prefix("/WEB-INF/views/").suffix(".jsp");
}
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
}
In controller use:
#Controller not #RestController
Like:
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
#Controller
public class TestController {
#RequestMapping(value = "/showHome", method = RequestMethod.GET)
public String homePage() {
return "index";
}
}
Sample Blog site application (git source code ) with Spring Boot and Hibernate you may get help from here.

Had to change my pom.xml file dependecies where i import tomcat-embed and javax.servelet to
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<version>8.5.20</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>

you should use #Controller if you want to return jsp file. #RestController returns a string
#Controller
public class HomeController {
#RequestMapping("/showHome")
public String homePage(){
return "index";
}
}
for configurations create WebConfig.java file and write in these:
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = {
"com.example.demo"
})
public class WebConfig implements WebMvcConfigurer {
#Bean
public InternalResourceViewResolver getInternalResourceViewResolver(){
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".jsp");
return resolver;
}
}

And the result is this: http://imgur.com/a/t0uNv
What exactly have i done wrong? I even have intellisence for the roles, i linked the correct dependecies i link the sec xml tag as well.

You don't need to use sec: extension for simple Spring Security integration.
Conditional block depending on role:
<div th:if="${#request.isUserInRole('ADMIN')}">
Za Admina
</div>
Print username:
<div th:text="${#request.userPrincipal.name}"></div>

i think it's caused by not having the spring security dialect added to the TemplateEngine. I'm not sure how you set up your WebMvcConfig, but as an example:
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.Ordered;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.thymeleaf.extras.springsecurity4.dialect.SpringSecurityDialect;
import org.thymeleaf.spring4.SpringTemplateEngine;
import org.thymeleaf.spring4.view.ThymeleafViewResolver;
import org.thymeleaf.templateresolver.ClassLoaderTemplateResolver;
import org.thymeleaf.templateresolver.TemplateResolver;
import org.thymeleaf.templateresolver.UrlTemplateResolver;
#Configuration
#EnableScheduling
#EnableTransactionManagement
public class WebMvcConfig extends WebMvcConfigurerAdapter {
#Bean
public TemplateResolver templateResolver() {
TemplateResolver templateResolver = new ClassLoaderTemplateResolver();
templateResolver.setPrefix("views/");
templateResolver.setSuffix(".html");
templateResolver.setTemplateMode("HTML5");
templateResolver.setCacheable(false);
return templateResolver;
}
#Bean
public UrlTemplateResolver urlTemplateResolver() {
return new UrlTemplateResolver();
}
#Bean
public SpringTemplateEngine templateEngine() {
SpringTemplateEngine templateEngine = new SpringTemplateEngine();
templateEngine.addTemplateResolver(templateResolver());
templateEngine.addTemplateResolver(urlTemplateResolver());
templateEngine.addDialect(new SpringSecurityDialect());
return templateEngine;
}
#Bean
public ViewResolver thymeleafViewResolver() {
ThymeleafViewResolver vr = new ThymeleafViewResolver();
vr.setTemplateEngine(templateEngine());
vr.setCharacterEncoding("UTF-8");
vr.setOrder(Ordered.HIGHEST_PRECEDENCE);
return vr;
}
}
Greetings
Marian
#Edit:
I added a complete Example of an WebMvcConfig. For this Example the Views would be located in Resources/views, but you can ofc set it up however you'd like to.

Spring with maven, jar packaging, not displaying welcome.jsp page

Hi I am using Spring boot with maven jar packaging. My project structure looks like this
I am starting my project from command promt with this command:
mvn package && java -jar target/ProjekatNekretnine-0.0.1.jar, and it starts perfect. Than I go to http://127.0.0.1:8080/api/users/home and I do not get my welcome.jsp page. My controller class looks like this:
UserController class:
package com.projekat.nekretnine.controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import com.projekat.nekretnine.Model.Korisnik;
#RestController
#RequestMapping(value="api/users")
public class UserController {
#RequestMapping(value = "/home")
public String welcome(Model model) {
return "welcome";
}
}
I think that my welcome method should return my welcome.jsp file, but instead it writes "welcome" to the page. Why is that so? What am I doing wrong?
My welcome.jsp file looks like this:
<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>Getting Started: Serving Web Content</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<h1>This is working.</h1>
</body>
</html>
So you see that it shouldn't write welcome.

One more thing, when I created maven project, I selected that the packaging should be JAR, not WAR. I don't know if I need now web.xml or other xml files, I think not. Maybe the mistake is where I put my static files, if that's the problem, can you tell me where to put tham?
And I tried to use #Controller, instead of #RestController in my UserController class, and still the same problem.
Thank you in advance.

The behaviour your are experiencing is normal.
This happens because you instructed your controller( specifically your rest-controller ) to return a String object when it hits /api/users/home endpoint.
If you however want to expose a page(view) in this endpoint you should configure your spring-boot to use a InternalResourceViewResolver.
You could take a look at a similar question Configure ViewResolver with Spring Boot and annotations gives No mapping found for HTTP request with URI error. and apply the changes for your controller to return the welcome page.
