java - org.springframework.beans.InvalidPropertyException : Invalid property 'id' of bean class

Question

我不明白为什么我在下面的保存中收到此错误。有什么线索吗？

org.springframework.beans.InvalidPropertyException: Invalid property 'id' of bean class [com.test.DataException]: Getter for property 'id' threw exception; nested exception is java.lang.reflect.InvocationTargetException

代码

try {
            DataException dataException = new DataException();
            dataException.tenant = job.tenant;
            dataExceptionRepository.save(dataException);
        } catch (Throwable ex) {

        }

DataException.java

@Entity
public class DataException {
    @Id
    @GeneratedValue
    public Long id;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "tenantId")
    public Tenant tenant;

    public String sourceSystem;
    public String objectType;
    public String objectId;
    public String description;
    public Date jobDate;

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

Answer 1

你的 getter 和 setter 需要是 Long 而不是 long
