How I Can deploy a SpringBoot Application in WildFly?

How I Can deploy a SpringBoot Application in WildFly? - java

I have a very simple CRUD in Java with SpringBoot, and locally it runs perfectly, but I need to upload the .war to a WildFly server. When I do this, it displays correctly, but when I try to consume a service from postman, or enter the context-root, I get "Forbbiden". What configuration should I do, or how can I call the URL?
REST CONTROLLER:
#RestController
#RequestMapping("/v1/ex-excepciones")
public class ExExcepcionesController {
private final ExExcepcionesService exExcepcionesService;
public ExExcepcionesController(ExExcepcionesService exExcepcionesService) {
this.exExcepcionesService = exExcepcionesService;
}
#GetMapping
public List<ExExcepcionesDto> findAll() {
return exExcepcionesService.findAll();
}
#GetMapping("/{id}")
ResponseEntity<ExExcepcionesDto> findById(#PathVariable long id) {
return new ResponseEntity<>(exExcepcionesService.findById(id), HttpStatus.OK);
}
#PostMapping
ResponseEntity<ExExcepcionesDto> create(#RequestBody ExExcepcionesRequest request) {
return new ResponseEntity<>(exExcepcionesService.save(request), HttpStatus.CREATED);
}
#PatchMapping("/{id}")
ResponseEntity<ExExcepcionesDto> update(#PathVariable Long id ,#RequestBody ExExcepcionesRequest request) {
return new ResponseEntity<>(exExcepcionesService.update(id,request), HttpStatus.OK);
}
Este es el Application:
#SpringBootApplication
public class SdmExcepcionesDeiApplication extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
#Bean
public WebMvcConfigurer corsConfigurer() {
return new WebMvcConfigurer() {
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedMethods("GET", "POST", "PUT", "DELETE", "PATCH", "OPTIONS");
}
};
}
#Override
public void onStartup(ServletContext servletContext) throws ServletException {
}
public static void main(String[] args) {
SpringApplication.run(SdmExcepcionesDeiApplication.class, args);
}
}

Entering the context-root of the wildfly throws this:
https://i.stack.imgur.com/BZTSn.png
https://i.stack.imgur.com/uwkJ5.png
and When trying to build the URL and consume the rest api:
http://127.0.0.1:8080/SDM/v1/ex-excepciones/
For localhost, it's the same.
http://localhost:8080/SDM/v1/ex-excepciones/

Many thanks to anyone who can help me with this.

Then I thought that it could be a problem with the controller that is not returning data or redirecting correctly but I can't think of what it could be
My controller
#RestController
public class PruebaController {
#Autowired
private PersonaService personaService;
#GetMapping(value="/index",produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Object> index(){
return ResponseEntity.ok(this.personaService.findAll());
}
}
The problem is that when I do the command -> "spring-boot:run" and go to the link I get -> Error 404
I am also sure that the connection to the database is made perfectly so I only have to rule out that the service is done wrong but I don't know what it could be
PersonaService.java
public interface PersonaService {
Page<PersonaDTO> findAll();
PersonaDTO findByNSS(String NSS);
PersonaDTO findByNumTarjeta(String numTarjeta);
void save(PersonaDTO paciente);
void saveAll(List<PersonaDTO> pacientes);
void deleteById(Long id);
}
and this is my file
PersonaImpl.java
package Services.Implementation;
import DTO.PersonaDTO;
import Repository.PersonaRepository;
import Services.Interfaces.PersonaService;
import Utils.MHelpers;
import com.example.demo.Persona;
import org.springframework.beans.factory.annotation.Autowired;

import java.util.Optional;
#Component
public class PersonaImpl implements PersonaService {
#Autowired
private PersonaRepository PersonaRepository;
#Override
public Page<PersonaDTO> findAll() {
Page<Persona> personas = this.PersonaRepository.findAll();
return personas.map(this::convertToPersonaDTO);
}
#Override
public PersonaDTO findByNSS(String NSS) {
Optional<Persona> personas = this.PersonaRepository.findByNSS(NSS);
if (!personas.isPresent()){
return null;
}
return MHelpers.modelMapper().map(personas.get(),PersonaDTO.class);
}
#Override
public PersonaDTO findByNumTarjeta(String numTarjeta) {
Optional<Persona> personas = this.PersonaRepository.findByNumTarjeta(numTarjeta);
if (!personas.isPresent()){
return null;
}
return MHelpers.modelMapper().map(personas.get(),PersonaDTO.class);
}
#Override
public void save(PersonaDTO personaDTO) {
Persona persona = MHelpers.modelMapper().map(personaDTO, Persona.class);
this.PersonaRepository.save(persona);
}
#Override
public void saveAll(List<PersonaDTO> personas) {
List<Persona> p = new ArrayList<>();
for (PersonaDTO persona: personas) {
Persona pers = MHelpers.modelMapper().map(persona,Persona.class);
p.add(pers);
}
this.PersonaRepository.saveAll(p);
}
#Override

for(Schema currentSchema: result) {

}
}

The problem you face is ObjectId becomes extended (Deserialized). we make it serialization.Add this dependency in pom
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.11.0.rc1</version>
</dependency>
Add the following method in main class.
#Bean
public Jackson2ObjectMapperBuilderCustomizer customizer()
{
return builder -> builder.serializerByType(ObjectId.class,new ToStringSerializer());
}
This will give you expected output.

In my case, using Kotlin it was so simple as to add a Jackson JSON serializer:
#JsonSerialize(using = ToStringSerializer::class)
val id: ObjectId = ObjectId.get(),
In order to get:
{
"id": "622b34af87c70514f6452363",
...
}
instead of:
{
"id": {
"timestamp": 1646998703,
"date": "2022-03-11T11:38:23.000+00:00"
},
...
}

Change your jasper dependency as

<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>

The dependency should be configured as with scope provided:

It is my understanding that the annotations should pick up the repository and create the bean based off of the #EnableCassandraRepositories annotation. The #Autowired ProductPriceRepository in ProductService.java is always null though when I run this on tomcat. HOWEVER, if I run a junit test against the service call, the bean is properly created, the object is not null, and the tests pass (via #ContextConfiguration annotation).
I've looked at a couple different patterns that I thought might help, but none of them have worked. I can't create an implementation of my interface because Cassandra handles that internally and I'm forced to implement the Cassandra methods.
I feel like something is just slightly off with the annotations somewhere. Any ideas?

The problem is with your pom.xml
For spring-boot Cassandra application, you have to include below dependencies and parent pom in pom.xml
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.5.RELEASE</version>
</parent>

Get a 404 error with simple spring-data-rest project

I'm trying to configure spring-data-rest over my spring-mvc project, but every time I enter the url to access json of my repository-info - it returns 404. Looks like it doesn't see my spring-data-rest annotation/dependency at all

So I enter the next URL "http://localhost:8080/lib-support/books"
and have this.
Could anyone help? Thanks in advance.

Okey guys, I found out what the problem was. I created reporitories classes not for all entity classes, as a result - Spring wasn't able to generate appropriate links for relative entities. For example I have Book entity, that have OneToMany mapping to BookCopy entity class, but BookCopyRepository was not exist.
