Estou com o seguinte problema:

Description:

Field repository in br.com.vinicius.lista.config.ConvidadoController required a bean of type 'br.com.vinicius.lista.repository.ConvidadoRepository' that could not be found.


Action:

Consider defining a bean of type 'br.com.vinicius.lista.repository.ConvidadoRepository' in your configuration.

Meu pom.xml

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <version>1.5.4.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
            <version>1.5.4.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
            <version>1.5.4.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.40</version>
        </dependency>


    </dependencies>

Meu Controller

@Controller
public class ConvidadoController {

    @Autowired
    private ConvidadoRepository repository;

    @RequestMapping("/")
    public String index() {
        return "index";
    }

    @RequestMapping("/listaconvidados")
    public String listaConvidados(Model model) {
        Iterable<Convidado> convidados = repository.findAll();
        model.addAttribute("convidadados", convidados);
        return "listaconvidados";
    }

}

Meu arquivo de configuração

@SpringBootApplication
public class Configuracao {

    public static void main(String[] args) {
        SpringApplication.run(Configuracao.class, args);
    }

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("com.mysql.jdbc.Driver");
        dataSource.setUrl("jdbc:mysql://localhost:3306/listavip");
        dataSource.setUsername("root");
        dataSource.setPassword("");

        return dataSource;
    }

}

Utilizando a versão 1.4.2.RELEASE no pom.xml também acontece o mesmo erro.

Utilizando a versão 1.4.1.RELEASE no pom.xml acontece o seguinte erro:

Fala Vinicius, tudo bem ?

Como está sua classe ConvidadoRepository ? Ela está anotada com @Repository ? O problema não é causado pela JPA, mas sim pelo container do Spring que não está conseguindo resolver a dependência do repository no controller. Possivelmente o container do Spring não está encontrando ou não tem controle sobre o objeto cuja implementação é gerada pelo Spring Data.

Exemplo:

//interface do Spring data
import org.springframework.data.repository.Repository;

@org.springframework.stereotype.Repository //para o Spring gerenciar o objeto 
public interface ConvidadoRepository extends Repository<Convidado, Integer> {

    ...
}

Espero ter ajudado. Abraço!

Olá Rafael! Bom e você?

Tentei fazer o que você sugeriu e não deu certo!

Fiz um teste que deu certo mas não sei porque comigo não funcionou e pelo vídeo do instrutor deu certo ... Aparentemente meu projeto não esta conseguindo identificar as classes que não estão no mesmo package do arquivo de configuração.

Com isso eu movi minha classe do do repository que estava dentro do package que eu havia criado br.com.vinicius.lista.repository para o package br.com.vinicius.lista.config em que se encontra o arquivo de configuração e a aplicação subiu sem problemas!

Poderia/saberia me explicar por que acontece isso? E como resolveria sem ter que deixar tudo em um único package? Obrigado!

solução!

Ah entendi. Faz sentido era uma das suspeitas, quando o Spring reclama por não achar um bean ao tentar satisfazer uma injeção de dependência, ou nossa classe não está anotada/registrada como componente/bean do Spring, ou ela pode até estar anotada mas talvez o container não a está encontrando na hora de fazer o scan das classes do projeto.

Em geral esse problema pode ser resolvido colocando a classe de inicialização/configuração (classe Boot do exemplo) no pacote base da aplicação.

package br.com.empresa.projeto;

@SpringBootApplication
public class Boot {

    public static void main(String[] args) {
        SpringApplication.run(Boot.class, args);        
    }
    ...
}

Dessa forma as demais classes ficarão normalmente cada uma em seu correspondente pacote, desde que ele seja um subpacote do pacote base da aplicação, o que é prática comum.

package br.com.empresa.projeto.repositories;

//interface do Spring data
import org.springframework.data.repository.Repository;

@org.springframework.stereotype.Repository //para o Spring gerenciar o objeto 
public interface ConvidadoRepository extends Repository<Convidado, Integer> {

    ...
}
package br.com.empresa.projeto.controllers;
...
@Controller 
public class ConvidadoController {

    @Autowired
    private ConvidadoRepository convidadoRepository;
    ...
}

Perceba que na classe Boot passamos como argumento pra SpringApplication.run a referência à própria classe - Boot.class. O metodo run então vai, entre outras coisas, iniciar o scan das classes do projeto a partir da classe Boot do seu pacote base, lendo assim também todo subpacote. Dessa forma ela vai conseguir achar seus controllers, repositories, services e components que você tenha registrado.

Tente fazer essa organização nos seus pacotes.

Espero ter ajudado. Abraço!
