Error 404 trying to access html page with RequestMapping

I have a simple Springboot application with thymeleaf. I created a formPaciente.html under src/main/resources/templates/pacientes , and a controller to map the URL, but I get error 404 while trying to access it, I did the same thing for index.html and it works.

project ls -R

ls -R
.:
main  test

./main:
java  resources

./main/java:
com  Controllers  models

./main/java/com:
Laudosapp

./main/java/com/Laudosapp:
laudosapp

./main/java/com/Laudosapp/laudosapp:
indexController.java  LaudosappApplication.java

./main/java/Controllers:
PacienteController.java

./main/java/models:
Paciente.java

./main/resources:
application.properties  static  templates

./main/resources/static:

./main/resources/templates:
index.html  pacientes

./main/resources/templates/pacientes:
formPaciente.html

./test:
java

./test/java:
com

./test/java/com:
Laudosapp

./test/java/com/Laudosapp:
laudosapp

./test/java/com/Laudosapp/laudosapp:
LaudosappApplicationTests.java

formPaciente.html

    <!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h1> Cadastro de pacientes</h1>
<form method="post">
    <input type=""text" value="" name="pacientenome"/>
    <input type=""text" value="" name="pacientesexo"/>
    <input type=""text" value="" name="pacientedatanasc"/>
    <input type=""text" value="" name="pacientedataexame"/>
    <input type=""text" value="" name="medicosolicitante"/>
    <input type=""text" value="" name="specmedica"/>
    <input type=""text" value="" name="hda"/>
    <input type=""text" value="" name="pacienteconvenio"/>

    <button type="submit">Salvar</button>
</form>
</body>
</html>

Controller

package Controllers;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class PacienteController {

    @RequestMapping("/cadastrarpaciente")
    public String form(){

        return "pacientes/formPaciente";
    }
}

Place PacienteController.java to ./main/java/com/Laudosapp/laudosapp: or Add @ComponentScan("Controllers") to Spring main application file.

It seems that you are you have placed your controller different sub package than spring SpringApplication file. So Controller is not accessible from Spring main()

Please add

@SpringBootApplication @ComponentScan("Controllers")

Or Place PacienteController.java to ./main/java/com/Laudosapp/laudosapp:

And for HTML tag error add to application.properties

spring.thymeleaf.mode=LEGACYHTML5

pom.xml
<dependency> <groupId>net.sourceforge.nekohtml</groupId> <artifactId>nekohtml</artifactId> </dependency>

It seems that you are sending an object from the .htm page but not receiving it in the backend controller. So have a look on this link
