Springboot won't load my HTML page using Thymeleaf

Springboot won't load my HTML page using Thymeleaf - java

Already been on these topics but haven't worked for me:
Topic1 No #EnableWebMvc annotation in my project
This is the dependency i used for Thymeleaf:
<!-- https://mvnrepository.com/artifact/org.thymeleaf/thymeleaf -->
<dependency>

My new Controller named ViewController
package myrest.Viewcontroller;
//Imports
#Controller
public class ViewController {
public static String uploadDirectory = System.getProperty("user.dir")+"/uploads";
#RequestMapping("/uploadendpoint")
public String uploadPage(Model model)
{
return "uploadView";
}
}
The HTML named uploadView.html
<!DOCTYPE html>

Whitelabel error page:

It is like M.Deinum said. You are using Spring Boot so get the benefits from using the starter packages. In the spring-boot-starter-thymleaf package are more dependencies included than just in the org.thymeleaf 3.0.11.RELEASE.
Replace this in your pom.xml:
<dependency>
<groupId>org.thymeleaf</groupId>
<artifactId>thymeleaf</artifactId>
<version>3.0.11.RELEASE</version>
</dependency>
with this:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
Then it works like charming.

Add dependency in your pom.xml:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
Add your Html file in src/main/resource/templates/test.html(select any name)
Then add this with html tag:
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org">
Create a Controller to open your html file:
#Controller
public class DemoController {
#GetMapping("/OpenTestFile")
public String OpenTestFile(Model model) {
return "test";
}
}
Open with this Url:
http://localhost:8082/OpenTestFile

Some times the IDE your using like intelliJ community version will not support MVC, please check with your IDE supports the requirements

Output when Get request is made via Postman:
yuty null
screenshot of postman request screenshot of postman headers
I have tested it via Jax-RS Rest and it working fine, the problem is only occurring for Spring-boot. Postman is hitting the backend code successfully but the data is not getting maapped in method paramater. I am sending text/plain from Postman.

Try with this:
#RestController
#RequestMapping("/incident")
public class EncryptJsonString {
#GetMapping("/test/{a}")
public String getTest(#PathVariable("a") String a) {
System.out.println("yuty "+a);
return a;
}
}
and then use http://localhost:8080/incident/test/whatever. It should print yuty whatever.

You have 2 approaches here. One is the one that Alessandro just write. (Thats the best, your method is a GET so you must use PathVariables or QueryParams).
If you're actually trying to send plain text in the body of the request, you should add the #RequestBody annotation to your method argument
Like this:
#GetMapping("/test")
public String getTest(#RequestBody String a) {
System.out.println("yuty "+a);
return a;
}
But remember, you should avoid sending a body if your request is a GET.

Spring Boot Kotlin API returns 404 response for all endpoints

I'm using Spring Boot with Kotlin . The rest controller returns 404 error for all endpoints. In the starting logs the endpoints in the controller are not present. Any endpoint returns the same 404 response.
These are the steps I have tried,
Tried clearing cache/target
Moved all classes into single directory
Tried adding ComponentScan annotation but it is not accepted.
I'm using cmd line to run the project
Same output seen when running java -jar $jarfile
Checked annotations Repository , Service , RestController

I guess your CricketerController is not in a subpackage relative to your main class. So you basically have two options:
Place your main class directly under the package com.example
Add the annotation at the bottom of this answer to your main class.
Using any of these two methods makes the controller class visible for Spring at startup and therefore should create your mappings.
#ComponentScan(basePackages = { "com.example.controller"} )

Springboot executable jar can not access index page

I created an application with springboot, restapi and angularjs. I will turn this project as executable jar. but when i do java -jar patchinit.jar, it does not reload index page. it gives
Whitelabel Error Page (There was an unexpected error (type=Not Found,
status=404 No message available)
Trying to http://localhost:8080/
Am i missing something? I almost tried everything desperately..

Project Structure as an image

Finally I got a solution. I was able to resolve this issue by adding thymeleaf dependency in pom
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
What is Thymeleaf?
Thymeleaf is a Java library. It is an XML/XHTML/HTML5 template engine that is able to apply a set of transformations to template files in order to display data and/or text produced by your applications.
There is one correction required in your html file:
<link rel="stylesheet"
href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css">
<link rel="stylesheet"
href="https://cdnjs.cloudflare.com/ajax/libs/angular-material/1.1.5/angular-material.min.css">
make sure to close this tag <link> with end tag </link>. Otherwise you will get below error
There was an unexpected error (type=Internal Server Error,
status=500). Exception parsing document: template="index", line 12 -
column 3

View not getting detected and throwing whitelabel error (Spring Boot Application)

I just started learning spring boot, and created a small spring mvc application. But I'm getting white label error when I try to access view, but application is working fine if i just return the string using responseBody annotation. I have also added thymeleaf to dependency.

Web App not serving static resources using Spring Boot and Tomcat

Hello I am having troubles 'serving' resources with my web server, while some of my other resources are 'serving.' (graphs.js is loading)
In my browser console:
GET http://localhost:8080/js/app.js [HTTP/1.1 400 Bad Request 2ms]
GET http://localhost:8080/includes/header.html [HTTP/1.1 400 Bad Request 4ms]
GET http://localhost:8080/cs/bootstrap.min.css [HTTP/1.1 400 Bad Request 3ms]
But these files are located in my directory as such:
css/
bootstrap.min.css
includes/
header.html
js/
app.js
controllers/
graphs.js
When my server starts:

You have not stated if you have followed instructions for packaging as a war instead of a JAR and bundling Tomcat in. This does change things a little. Either way, take a look at the documentation here: http://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#boot-features-spring-mvc-static-content
Bascally, out of the box, you can place static content in one of the locations mentioned: /static, /public, /resources or /META-INF/resorces. As for the location of these folders, well either at the root of the servlet context or on the classpath.
You can find a very basic Tomcat application here: https://github.com/mmeany/spring-boot-web-mvc that does the job.
