Question

我为现有的jhipster实体添加了liquibase类型时间戳的新字段，后端是mysql。

<changeSet author="mnkb" id="20151008151559">
       <addColumn schemaName="sample"
            tableName="invoice">       
         <column name="bill_date" type="timestamp"/>
    </addColumn>
</changeSet>

从我的角度js前端请求如下：

{"accountNumber":"AC6434364","invoiceNumber":"IN67347643","invoiceAmount":326,"status":"open","ediNumber":"6565EDI","billDate":"2012-05-02T17:07:00.000Z","id":null}

我的REST调用Debug日志如下：

[DEBUG] com.sample.aop.logging.LoggingAspect - Enter: com.sample.web.rest.InvoiceResource.create() with argument[s] = [Invoice{id=null, accountNumber='AC6434364', invoiceNumber='IN67347643', invoiceAmount='326.0', ediNumber='6565EDI', status='open', billDate='2012-05-02T22:37:00.000+05:30'}]

由于此错误，此特定记录未插入，之前当我没有billDate CRUD操作正常工作时。

在Invoce.java中，我有

import org.hibernate.annotations.Cache;
import org.hibernate.annotations.CacheConcurrencyStrategy;
import org.joda.time.DateTime;

import javax.persistence.*;
import java.io.Serializable;
import java.util.HashSet;
import java.util.Set;
import java.util.Objects;

 @Column(name = "bill_date")
    private DateTime billDate;


        public DateTime getBillDate() {
            return billDate;
        }

        public void setBillDate(DateTime billDate) {
            this.billDate = billDate;
        }

@Override
    public String toString() {
        return "Invoice{" +
                "id=" + id +
                ", accountNumber='" + accountNumber + "'" +
                ", invoiceNumber='" + invoiceNumber + "'" +
                ", invoiceAmount='" + invoiceAmount + "'" +
                ", ediNumber='" + ediNumber + "'" +
                ", status='" + status + "'" +
                ", billDate='" + billDate + "'" +
                '}';
    }

以下内容显示在我的浏览器控制台中。

POST http://localhost:8080/api/invoices?cacheBuster=1444330431628 500 (Internal Server Error)

timestamp: 1444330431767, status: 500, error: "Internal Server Error",…}

任何人都可以帮我解决这个billDate插入失败问题吗？

您需要添加注释：@Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTime")和@JsonSerialize(using = DateTimeSerializer.class)，如：

@Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTime")
@JsonSerialize(using = DateTimeSerializer.class)
@Column(name = "bill_date")
private DateTime billDate;

// Getter and setter...
