[英]Spring Data JPA save() return entity
I am using spring boot data jpa as below我正在使用弹簧启动数据 jpa 如下
@Entity
@Table(name = "invoice")
@Getter
@Setter
@ToString
public class Invoice {
@Id
@Column(name = "inv_id")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private BigInteger invId;
@Column(name = "external_id")
private String externalInvoiceId;
@Column(name = "amount")
private double amount;
@JsonIgnore
@JsonIgnoreProperties
@Column(name = "status")
private int status;
@JsonProperty("status")
@Transient
private String invoiceStatus;
public String getInvoiceStatus() {
switch (this.status){
case 1:
return "INITIATED";
case 2:
return "CANCELLED";
case 3:
return "SUCCESS";
case 4:
return "FAILURE";
default:
return "IN PROGRESS";
}
}
@CreationTimestamp
@Temporal(TemporalType.TIMESTAMP)
@Column(name = "created_at")
private Date createdAt;
@UpdateTimestamp
@Temporal(TemporalType.TIMESTAMP)
@Column(name = "updated_at")
private Date updatedAt;
@PostPersist
public void updateExternalID() {
this.externalInvoiceId="G".concat(String.valueOf(this.invId.multiply(BigInteger.valueOf(1000))))
.concat(String.valueOf(Instant.now().getEpochSecond()));
}
}
Am accesing this entiry via repository as below我正在通过存储库访问此条目,如下所示
public interface InvoicesRepository extends JpaRepository<Invoice, BigInteger> {
}
At my @Service
am performing the below operation在我的
@Service
执行以下操作
@Autowired
private InvoicesRepository myInvoicesRepository;
Invoice transactionInvoice = new Invoice();
transactionInvoice.setAmount(200.0);
transactionInvoice.setStatus(1);
Invoice savedInvoice = myInvoicesRepository.save(transactionInvoice);
Am using savedInvoice
and trying to update the status.正在使用
savedInvoice
并尝试更新状态。 Either it is not updating the status properly nor I could not find the record in database too.要么它没有正确更新状态,要么我也找不到数据库中的记录。
There are no rollback present不存在回滚
Below are the logs I could see insert statements are present以下是我可以看到存在插入语句的日志
[XNIO-1 task-1] DEBUG org.hibernate.SQL.logStatement -
/* insert com.min.app.model.Invoice
*/ insert
into
invoice
(amount, created_at, external_inv_id, status, updated_at)
values
(?, ?, ?, ?, ?)
Hibernate:
/* insert com.min.app.model.Invoice
*/ insert
into
invoice
(amount, created_at, external_inv_id, status, updated_at)
values
(?, ?, ?, ?, ?)
After the status updates I tried printing the savedInvoice
could see the below in logs状态更新后,我尝试打印
savedInvoice
可以在日志中看到以下内容
Invoice(invId=58, externalInvoiceId=G580001575271905, amount=185.0 status=4, invoiceStatus=FAILURE, createdAt=Mon Dec 02 13:01:45 IST 2019, updatedAt=Mon Dec 02 13:01:45 IST 2019)
The above record I could not see in the table.上面的记录我在表中看不到。
What am I doing wrong?我究竟做错了什么?
you need to perform transactions in a function call as follows and put your @Autowired repository in Global level ass follows.您需要按如下方式在函数调用中执行事务,并将您的 @Autowired 存储库放在如下全局级别中。
class whatever{
@Autowired
private InvoicesRepository myInvoicesRepository;
//call this function
void doSomething(){
Invoice transactionInvoice = new Invoice();
transactionInvoice.setAmount(200.0);
transactionInvoice.setStatus(1);
Invoice savedInvoice = myInvoicesRepository.save(transactionInvoice);
}
}
