Spring Repository Bean Not Being Found

Question

我试图用spring在postgres中做一个简单的CRUD，但没有任何原因，我的IoD机制不工作并抛出这样的错误:

Description:
Parameter 0 of constructor in br.com.maptriz.formulario_dinamico.service.FormularioDinamicoService required a bean of type 'br.com.maptriz.formulario_dinamico.repository.FormularioDinamicoRepository' that could not be found.

Action:
Consider defining a bean of type 'br.com.maptriz.formulario_dinamico.repository.FormularioDinamicoRepository' in your configuration.

下面是我的代码:

FormularioDinamicoApplication.java

package br.com.maptriz.formulario_dinamico;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
// @EnableJpaRepositories("br.com.maptriz.formulario_dinamico.repository")
// @EnableScheduling
// @EnableDiscoveryClient
// @ComponentScan
@SpringBootApplication
public class FormularioDinamicoApplication {
public static void main(String[] args) {
SpringApplication.run(FormularioDinamicoApplication.class, args);
}
}

FormularioDinamico

package br.com.maptriz.formulario_dinamico.model;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;
@Entity
@Table(name = "formulario_dinamico")
public class FormularioDinamico {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@ManyToOne
@JoinColumn(name="tipo_tabela")
private Long tabelaId;
private String name;
private String campos;
protected FormularioDinamico() {}

public FormularioDinamico(Long tabelaId, String name, String campos) {
this.tabelaId = tabelaId;
this.name = name;
this.campos = campos;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public Long getTabelaId() {
return this.tabelaId;
}
public void setTabelaId(Long tabelaId) {
this.tabelaId = tabelaId;
} 
public String getName() {
return this.name;
}
public void setObservacao(String name) {
this.name = name;
}
public String getCampos() {
return this.campos;
}
public void setCampos(String campos) {
this.campos = campos;
}
@Override
public String toString() {
return "EntidadeGenerica{" +
"id=" + id +
", dataAtualizacao=" + tabelaId +
", dataCadastro=" + name +
", observacao='" + campos + '}';
}
}

FormlarioDinamicoController.java

package br.com.maptriz.formulario_dinamico.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import br.com.maptriz.formulario_dinamico.model.FormularioDinamico;
import br.com.maptriz.formulario_dinamico.service.FormularioDinamicoService;
@RestController
@RequestMapping
public class FormularioDinamicoController {
private final FormularioDinamicoService service;
@Autowired
public FormularioDinamicoController(FormularioDinamicoService service) {
this.service = service;
}
// @GetMapping
// public List<DynamicForm> getDynamicForm() {
//     return dynamicFormService.getDynamicForm();
// }

@PostMapping("/create")
public void registrarNovoFormularioDinamico(@RequestBody FormularioDinamico formularioDinamico) {
System.out.println("TEST");
service.adicionarNovoFormularioDinamico(formularioDinamico);
}
}

FormularioDinamicoService.java

package br.com.maptriz.formulario_dinamico.service;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import br.com.maptriz.formulario_dinamico.model.FormularioDinamico;
import br.com.maptriz.formulario_dinamico.repository.FormularioDinamicoRepository;
@Service
public class FormularioDinamicoService {

private final FormularioDinamicoRepository repository;
@Autowired
public FormularioDinamicoService(FormularioDinamicoRepository repository) {
this.repository = repository;
}
// public List<DynamicForm> getDynamicForm() {
//  return dynamicFormRepository.findAll();
// }
public void adicionarNovoFormularioDinamico(FormularioDinamico formularioDinamico) {
List<FormularioDinamico> topicos = repository.findAll();
System.out.println("HEREEEE");
System.out.println(topicos);
}
}

最后是FormularioDinamicoRepository.java

package br.com.maptriz.formulario_dinamico.repository;
import java.util.List;
import org.springframework.data.jpa.repository.JpaRepository;
import br.com.maptriz.formulario_dinamico.model.FormularioDinamico;

public interface FormularioDinamicoRepository
extends JpaRepository<FormularioDinamico, Long> {
List<FormularioDinamico> findAll();
}

文件夹结构:

• src
  • 主要
    • java/br/com/maptriz/formulario_dinamico控制器
      • <
      • 库/gh>
      • FormularioDinamicoApplication.java

Answer 1

在接口FormularioDinamicoRepository上添加@Repository注释。它应该可以无缝地工作。

当您添加它时，spring将其识别为bean并创建一个对象，并将bean注入到自动连接的任何地方。
