java – 这是一个有效的日期格式 – 2007-12-13 01:00？

是的,请参阅以下链接以获取格式的官方说明：

你的错误

We found out,that we receive the date in such format:
2007-12-13+01:00 and it throws out an exception:
java.lang.NumberFormatException: Invalid date/time

这似乎是Axis中的错误而不是JAXB.

在JAXB中处理此格式

下面是在JAXB中使用此格式的示例.

Java模型

在此示例中,我们将使用Date,Calendar和XMLGregorianCalendar来处理日期：

import java.util.*;
import javax.xml.bind.annotation.*;
import javax.xml.datatype.XMLGregorianCalendar;

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class Foo {

    private Date date;
    private Calendar cal;
    private XMLGregorianCalendar xgc;

}

演示代码

input.xml中

下面是我们将解组的XML文档,请注意所有日期值与您的问题中的相同.

<?xml version="1.0" encoding="UTF-8"?>
<foo>
    <date>2007-12-13+01:00</date>
    <cal>2007-12-13+01:00</cal>
    <xgc>2007-12-13+01:00</xgc>
</foo>

演示

下面是一些演示代码,我们将解组XML文档以填充每个日期字段,然后将对象封送回XML.

import javax.xml.bind.*;
import java.io.File;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance(Foo.class);

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        File xml = new File("input.xml");
        Foo foo = (Foo) unmarshaller.unmarshal(xml);

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT,true);
        marshaller.marshal(foo,System.out);
    }

}

产量

下面是运行演示代码的输出,我们看到所有值都已正确转换.请注意,日期和日历值默认为默认的dateTime表示.您可以使用@XmlSchemaType批注来控制它.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<foo>
    <date>2007-12-12T18:00:00-05:00</date>
    <cal>2007-12-13T00:00:00+01:00</cal>
    <xgc>2007-12-13+01:00</xgc>
</foo>
