jaxb解组日期

有没有简单的方法可以将日期解组为Java日期

例如，假设我们有以下xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<msg>
<type>SCH</type>
<msgName>SCHEvent</msgName>
<eventName>BST001</eventName>
<startDatetime>2012-09-12 11:00:00</startDatetime>
<endDatetime>2012-09-12 11:30:00</endDatetime>

</hl7msg>

我尝试了上面的解组，发现除了日期之外，所有其他属性都被分配给这个pojo。我认为我们可以使用XmlAdapter解决这个问题，但这需要创建额外的类。有没有简单的方法可以将此xml文本日期转换为Java日期？

实现支持

Java.util.Date

而不使用

XmlAdapter

，只要值与xml架构日期时间格式匹配（请参阅：。您的示例与此格式不匹配，因此需要使用

XmlAdapter

）

示例

如果在包级别使用

@XmlJavaTypeAdapter

注释，那么它将应用于该包中该类型的所有字段/属性

JAXB和容错

在JAXB（JSR-222）中专家组遇到的文档与其对应的XML不匹配的比例很高，因此我们决定默认情况下不会在每次遇到错误时都失败。您可以通过在

解组器上指定
ValidationEventHandler
来访问错误，方法是执行以下操作以查看错误

演示

UM12400173包；
导入java.io.File；
导入javax.xml.bind.*；
公开课演示{
公共静态void main（字符串[]args）引发异常{
JAXBContext jc=JAXBContext.newInstance（SCHEvent.class）；
文件xml=新文件（“src/forum12400173/input.xml”）；
Unmarshaller Unmarshaller=jc.createUnmarshaller（）；
unmarshaller.setEventHandler（新的ValidationEventHandler（）{
@凌驾
公共布尔handleEvent（ValidationEvent事件）{
event.getLinkedException（）.printStackTrace（）；
返回true；
}
});
SCHEvent事件=（SCHEvent）unmarshaller.unmarshal（xml）；
}
}

输出（JAXB-RI）
