In the main method it works, so what's the problem with springboot, I've looked, but nothing solves, does anyone have any idea what may be happening, dependency, spring configuration, hibernate configuration, pom.xml configuration, project configuration, anything?
I added EntityScan but the error continued.
package br.com.api;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
@SpringBootApplication
@EntityScan(basePackages = "br.com.api.entities")
public class ApiApplication {
public static void main(String[] args) {
SpringApplication.run(ApiApplication.class, args);
}
}
api I'm using: https://github.com/Eduardo-Karpinski/hcf
In an attempt to solve the problem, I modified my code to a model closer to what Spring wants, but the error continues.
package br.com.api;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import br.com.hcf.HCFFactory;
@Configuration
@EntityScan(basePackages = "br.com.api.entities")
public class Config {
@Bean
public HCFFactory factory() {
HCFFactory factory = HCFFactory.getInstance();
return factory;
}
}
package br.com.api.controls;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import br.com.api.entities.Persona;
import br.com.hcf.HCFConnection;
import br.com.hcf.HCFFactory;
@RestController
@RequestMapping("api/v1/public")
public class CharacterControl {
@Autowired
HCFFactory factory;
@GetMapping("/characters")
public ResponseEntity<Object> getAll() {
try {
factory.getFactory();
factory.getAnnotatedClasses();
return ResponseEntity.ok(new HCFConnection<>(Persona.class).all());
} catch (Exception e) {
e.printStackTrace();
return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body(e.getMessage());
}
}
}
During the debugging of the MetamodelImpl class I discovered that the error presented to me is impossible because my class that I want to persist is in Map "** jpaEntityTypeMap **".
Value of variables in the debug:
jpaEntityTypeMap ConcurrentHashMap <K, V> (id = 135)
[0] ConcurrentHashMap $ MapEntry <K, V> (id = 252)
key Class <T> (br.com.api.entities.Persona) (id = 156)
value EntityTypeImpl <J> (id = 157)
cls Class <T> (br.com.api.entities.Persona) (id = 244)
I'm starting to think it's a spring boot bug
while running other tests, I realized that when running the following block in the CharacterControl class
public static void main(String[] args) {
HCFFactory.getInstance().getFactory();
HCFFactory.getInstance().getAnnotatedClasses();
new HCFConnection<>(Persona.class).all().forEach(System.out::println);
}
the same error is thrown because the ** jpaEntityTypeMap ** is null, but when I run on the Persona class, there is no error, what does that mean?
With this change the same mistake happened, spring does not like me.

Solution
I tested your Controller code in a project and it works fine, I didn't include spring-boot-starter-data-jpa since you want to build the session factory your self:
