这个问题在这里已经有答案了：

spring数据jpa存储库-实体列名上的下划线（4个答案）
24天前关门。
我遇到抽象类错误，创建名为的bean时出错。
org.springframework.beans.factory.unsatifieddependencyException:创建名为..的bean时出错。。通过字段表示的未满足的依赖关系。。。。。。

我有以下错误：

当您在jpa存储库中编写自定义方法时，spring会尝试在可能的情况下自动实现其中的一些方法。在此阶段，spring检查方法的名称，并尝试将名称与实体字段匹配。
所以如果我们有

@Entity 
   public class MyEntity {

    private MyField1 myCustomField1
   }

  public class MyField1 {
    private String myString;
  }

如果您为 MyEntity 您可以声明以下方法，spring将理解您的意思并自动实现它们。

List<MyEntity>  findByMyCustomField1MyString(String val); //Camel Case seperates entity Fields

 or

 List<MyEntity>  findByMyCustomField1_myString(String val); // _ seperates entity fields

所以在spring的方法名求值过程中，\充当字段分隔符

你的代码有什么问题

在你的 Despache 实体有一个名为 funcionario_resp . 因此，您必须在存储库中声明以下方法

public List<Despache> findByFuncionario_respId(Long funcionario_respId, Pageable page);

我已经解释过了 _ 作为磁场分离器工作。因此，spring对方法名称的理解如下：

1) a field with name funcionario exists
  2) funcionario is a Class that contains a field with name respId

如何修复代码

重构以下字段

@Entity
public class Despache implements Serializable{
@Valid
    private Funcionario_resp funcionario_resp;

     ....

}

到

@Entity
public class Despache implements Serializable{
@Valid
    private Funcionario_resp funcionarioResp;

     ....

}

然后在存储库中重构方法

public List<Despache> findByFuncionario_respId(Long funcionario_respId, Pageable page);

这样地

@Repository
public interface DespacheRepository extends JpaRepository<Despache, Long>{

    public List<Despache> findByFuncionarioRespId(Long funcionario_respId, Pageable page);
     ...  
}
