异常文本说“没有为类型找到属性fid”（原文如此！），我试图谷歌但却没有得到任何东西。可能它代表“功能ID”，但我不知道它是怎么回事。我如何解决它？我班上有什么问题吗？
我的属性类：
@Entity
@Table(name = "LAB3_ATTRIBUTES")
public class Attribute {
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE)
@Column(name = "ATTR_ID", length = 10, nullable = false)
private Integer id;
@Column(name = "NAME")
private String name;
@ManyToOne
@JoinColumn(name = "OBJECT_TYPE_ID", referencedColumnName = "OBJECT_TYPE_ID")
private ObjectType objectType;
@OneToMany(mappedBy = "attribute", cascade = CascadeType.ALL)
private List<Parameter> parameters;
public Attribute() {
}
public Attribute(String name, ObjectType objectType) {
this.name = name;
this.objectType = objectType;
}
public Integer getId() {
return id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public ObjectType getObjectType() {
return objectType;
}
public void setObjectType(ObjectType objectType) {
this.objectType = objectType;
}
public List<Parameter> getParameters() {
return parameters;
}
public void setParameters(List<Parameter> parameters) {
this.parameters = parameters;
}
}
我的AttributeRepository接口：
public interface AttributeRepository extends JpaRepository<Attribute, Integer > {
Attribute findById(int id);
List<Attribute> findByName(String name);
List<Attribute> fidByObjectType(ObjectType objectType);
}
我的AttributeService接口：
public interface AttributeService {
void save(Attribute attribute);
Attribute findById(int id);
List<Attribute> findByName(String name);
List<Attribute> findByObjectType(ObjectType objectType);
}
我的AttributeServiceImpl类：
@Service
public class AttributeServiceImpl implements AttributeService {
@Autowired
private AttributeRepository attributeRepository;
public void save(Attribute attribute) {
attributeRepository.save(attribute);
}
public Attribute findById(int id) {
return attributeRepository.findById(id);
}
public List<Attribute> findByName(String name) {
return attributeRepository.findByName(name);
}
public List<Attribute> findByObjectType(ObjectType objectType) {
return attributeRepository.fidByObjectType(objectType);
}
}

答案 0 :(得分：1)
你在这一行有一个错字：
List<Attribute> fidByObjectType(ObjectType objectType);
应该是
List<Attribute> findByObjectType(ObjectType objectType);
由于拼写错误，Spring Data正在寻找一个名为“fid”的属性，当然不存在。
