microservice seems to work, but there's no data displayed - postgresql

Question

I have a simple app that's supposed to connect to postgres and display content of one of the tables.
I installed postgres, created a table and inserted a row, but nothing is shown when I run it.
This are my application.properties
spring.datasource.url=jdbc:postgresql://localhost:5432/postgres
spring.datasource.username=name
spring.datasource.password=pass
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
spring.jpa.hibernate.ddl-auto = update
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true
and this is repository interface
#Repository
public interface TaxonRepository extends CrudRepository<Taxon, Long> {
}
and the model
#Entity
#Table(name = "dim_taxon")
public class Taxon{
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Getter #Setter
private Long id;
#Getter #Setter
private String name;
#Getter #Setter
private String value;
#Getter #Setter
private String reserve;
#Getter #Setter
private String source;
}
My service
#Service
public class TaxonService implements TaxonServiceI{
#Autowired
private TaxonRepository repository;
#Override
public List<Taxon> findAll() {
return (List<Taxon>) repository.findAll();
}
}
and controller
#Controller
public class TaxonController {
#Autowired
private TaxonServiceI taxonService;
#RequestMapping(value="/showTaxons")
public String homePage(Model model){
List<Taxon> taxons = taxonService.findAll();
model.addAttribute("taxons", taxons);
return "index";
}
}
I tried to add an object manually to check if there was a problem with the html or smth
List<Taxon> taxons = new ArrayList<>();
Taxon taxon1 = new Taxon();
taxon1.setName("a");
taxon1.setReserve("a");
taxon1.setSource("a");
taxon1.setValue("a");
taxons.add(taxon1);
model.addAttribute("taxons", taxons);
but html is fine. Seems like this
List<Taxon> taxons = taxonService.findAll();
doesn't work. What's the problem here? There aren't actually any errors.
My table and the data.

Answer 1

You are not adding your loaded List<Taxon> to the model.
#RequestMapping(value="/showTaxons")
public String homePage(Model model){
List<Taxon> taxons = taxonService.findAll();
return "index";
}
Just returns the page to render, without modifying the model.
So this should work
#RequestMapping(value="/showTaxons")
public String homePage(Model model){
model.add(taxonService.findAll());
return "index";
}

Answer 2

In the end I added a few more anotations
#Data
#NoArgsConstructor
#AllArgsConstructor
#Validated
#Entity
#Table(name = "table name")
And explicit mapping for columns
#Column(name = "column_name")
this helped
