Spring Boot Ambiguous mapping. Cannot map method

I have 2 REST controllers in my Spring Boot application with simple CRUD operations.

REST controller, that is mapped to "/json/currency"

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);
    }
}

and REST controller, that is mapped to "/json/account"

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);
    }

}

While I start my application I have an exception and I do not understand why it happens.

Process finished with exit code 1

After I remove one of the REST controllers the application runs successfully. What should I do to solve this issue?

@RestController("/json/currency") is different from

@RestController @RequestMapping("/json/currency")

Read @RestController documentation here https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/bind/annotation/RestController.html

change your declaration like this

@RestController @RequestMapping("......") in both the classes. It should work
