Я работаю над простым приложением Springboot, оно не работает так, как я намеревался

/ 03 мая 2020

Я работаю над простым приложением Springboot, оно не работает так, как я намеревался. Может кто-нибудь указать мне, что я делаю не так. Если я не использую ломбок, а просто использую старые добрые традиционные методы получения и установки, он работает так, как задумано. Был бы признателен, если бы кто-то указал fl aws в этом коде.

Account. java

    package com.example.accountFetch.model;

    import javax.persistence.Entity;
    import javax.persistence.Id;

    import lombok.AllArgsConstructor;
    import lombok.Data;
    import lombok.NoArgsConstructor;

    @Data
    @AllArgsConstructor
    @NoArgsConstructor
    @Entity
    public class Account {

        @Id
        private int id;
        private long accountNumb;
        private String acType;
}

AccountService. java

package com.example.accountFetch.Service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.web.bind.annotation.RequestBody;

import com.example.accountFetch.model.Account;
import com.example.accountFetch.repo.AccountRepo;

@Service
public class AccountService {

    @Autowired
    AccountRepo accountRepo;

    public Account getAccountDetails(@RequestBody Account accountNumber) {
        return accountRepo.getAccountDetails(accountNumber.getAccountNumb());
    }
}

AccountController. java

package com.example.accountFetch.controller;

@Controller
@RequestMapping("/")
public class AccountController {

    @Autowired
    AccountService accountService;

    @RequestMapping("/{id}")
    public String login() {
        return"Eureka!";
    }

    @RequestMapping("/account/{accountNumb}")
    public Account getAccounts(@PathVariable("accountNumb")Account accountNumber) {

        return accountService.getAccountDetails(accountNumber);
    }

}

AccountRepo. java

package com.example.accountFetch.repo;

import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.CrudRepository;
import org.springframework.data.repository.query.Param;

import com.example.accountFetch.model.Account;

public interface AccountRepo extends CrudRepository<Account, Integer>{

    @Query(value = "SELECT * from Account f WHERE f.ACCOUNT_NUMB = :accNo" , nativeQuery = true)
    public Account getAccountDetails(@Param("accNo") long accNumb);

}

data. sql

insert into account values (1, 'Savings', 100089);

Метод getAccounts вашего контроллера сопоставлен с запросом с /account/{accountNumb} URL. Переменная {accountNumb} соответствует свойству accountNumb POJO вашей учетной записи, и именно так оно устанавливается в свойстве accountNumb. Если вы измените {accountNumb} на {id}, то значение будет установлено в id объекта Account.

POJO не требует никаких дополнительных аннотаций. Он должен иметь список полей, которые соответствуют параметрам запроса, которые будут связаны с HTTP-запросом, стандартными средствами получения / установки и конструктором без аргументов.

Для получения дополнительной информации проверьте эту ссылку Связывание данных параметров запроса пружины
