To retrieve and display user details from a PostgreSQL database in a Thymeleaf HTML format during the spring season using Java Spring framework, follow these steps:
First, make sure to configure the PostgreSQL database properly in the Spring application context file.
Create a User entity class with appropriate attributes and getters/setters.
Create a UserRepository interface that extends the JpaRepository interface, which provides CRUD operations for the User entity.
Create a UserController class with a method that retrieves all users from the database and passes them to the Thymeleaf template.
@Controller
public class UserController {
@Autowired
private UserRepository userRepository;
@GetMapping("/users")
public String getAllUsers(Model model) {
List<User> users = userRepository.findAll();
model.addAttribute("users", users);
return "user_list";
}
}
