我的Spring Boot应用程序中有2个REST控制器，只有简单的CRUD操作。
REST控制器，映射到＆＃34; / json / currency＆＃34;
package ua.alekstar.moneysaver.rest;
import org.springframework.web.bind.annotation.*;
import ua.alekstar.moneysaver.rest.currency.Currencies;
import ua.alekstar.moneysaver.rest.currency.Currency;
import ua.alekstar.moneysaver.service.CurrencyService;
import java.util.Collections;
@RestController("/json/currency")
public class CurrencyJsonRestController {
private final CurrencyService currencyService;
public CurrencyJsonRestController(CurrencyService currencyService) {
this.currencyService = currencyService;
}
@GetMapping
@ResponseBody
public Currencies get(@RequestParam(required = false) Long id) {
if (id == null) {
return readAll();
}
return read(id);
}
private Currencies read(Long id) {
return new Currencies(Collections.singletonList(currencyService.read(id)));
}
private Currencies readAll() {
return new Currencies(currencyService.readAll());
}
@PostMapping
public void post(@RequestBody Currency currency) {
currencyService.create(currency.toEntity());
}
@PutMapping
public void put(@RequestBody Currency currency) {
currencyService.update(currency.toEntity());
}
@DeleteMapping
public void delete(@RequestParam Long id) {
currencyService.delete(id);
}
}
和REST控制器，映射到＆＃34; / json / account＆＃34;
package ua.alekstar.moneysaver.rest;
import org.springframework.web.bind.annotation.*;
import ua.alekstar.moneysaver.dao.entities.Currency;
import ua.alekstar.moneysaver.rest.account.Account;
import ua.alekstar.moneysaver.rest.account.Accounts;
import ua.alekstar.moneysaver.service.AccountService;
import ua.alekstar.moneysaver.service.CurrencyService;
import java.util.Collections;
@RestController("/json/account")
public class AccountJsonRestController {
private final AccountService accountService;
private final CurrencyService currencyService;
public AccountJsonRestController(AccountService accountService, CurrencyService currencyService) {
this.accountService = accountService;
this.currencyService = currencyService;
}
@GetMapping
@ResponseBody
public Accounts get(@RequestParam(required = false) Long id) {
if (id == null) {
return readAll();
}
return read(id);
}
private Accounts read(Long id) {
return new Accounts(Collections.singletonList(accountService.read(id)));
}
private Accounts readAll() {
return new Accounts(accountService.readAll());
}
@PostMapping
public void post(@RequestBody Account account) {
accountService.create(toEntity(account));
}
private ua.alekstar.moneysaver.dao.entities.Account toEntity(Account account) {
final Currency currency = currencyService.readByIsoCode(account.getCurrency());
return new ua.alekstar.moneysaver.dao.entities.Account(account.getId(), account.getName(), currency);
}
@PutMapping
public void put(@RequestBody Account account) {
accountService.update(toEntity(account));
}
@DeleteMapping
public void delete(@RequestParam Long id) {
accountService.delete(id);
}
}
当我启动我的应用程序时，我有一个例外，我不明白它为什么会发生。
