如何将一个xml文件转换为简单的java bean？ 它是一个简单的xml文件，没有任何xsd，它是从我没有访问的java bean生成的。将xml转换为java bean

我尝试使用xmlbeans首先从xml生成xmd，然后从xsd生成类。我有一堆课。我正在寻找一个单独的java bean类。

您可以使用像Castor或JAXB这样的工具将XML映射到java类。 Castor相当容易使用。

JAXB

JAXB（JSR-222）提供了一种简单的方法将对象转换为XML。有此标准的许多开放源代码实现，包括：（包含在Java SE 6的参考实现）

  • EclipseLink JAXB (MOXy)

    JAXB具有Java对象到XML的默认映射。该映射可以通过应用注释来定制。

    import javax.xml.bind.annotation.XmlRootElement; 
import javax.xml.bind.annotation.Element; 

@XmlRootElement 
public class Address { 

    private String street; 

    private String city; 

    private String state; 

    private String country; 

    @XmlElement(name="postal-code") 
    private String postalCode; 

}

    将对应于下面的XML：

    <address> 
    <street>123 A Street</street> 
    <city>Any Town</city> 
    <state>A State</state> 
    <postal-code>12345</postal-code> 
</address>

    的EclipseLink JAXB（MOXY）

    MOXY具有基于XPath映射扩展。这意味着我们可以把我们的同一个Address类，并将其映射到谷歌的地理编码格式：

    import javax.xml.bind.annotation.XmlRootElement; 
import javax.xml.bind.annotation.XmlType; 

import org.eclipse.persistence.oxm.annotations.XmlPath; 

@XmlRootElement(name="kml") 
@XmlType(propOrder={"country", "state", "city", "street", "postalCode"}) 
public class Address { 

    @XmlPath("Response/Placemark/ns:AddressDetails/ns:Country/ns:AdministrativeArea/ns:SubAdministrativeArea/ns:Locality/ns:Thoroughfare/ns:ThoroughfareName/text()") 
    private String street; 

    @XmlPath("Response/Placemark/ns:AddressDetails/ns:Country/ns:AdministrativeArea/ns:SubAdministrativeArea/ns:Locality/ns:LocalityName/text()") 
    private String city; 

    @XmlPath("Response/Placemark/ns:AddressDetails/ns:Country/ns:AdministrativeArea/ns:AdministrativeAreaName/text()") 
    private String state; 

    @XmlPath("Response/Placemark/ns:AddressDetails/ns:Country/ns:CountryNameCode/text()") 
    private String country; 

    @XmlPath("Response/Placemark/ns:AddressDetails/ns:Country/ns:AdministrativeArea/ns:SubAdministrativeArea/ns:Locality/ns:PostalCode/ns:PostalCodeNumber/text()") 
    private String postalCode; 

}

    上面的类对应于以下XML：

    <?xml version="1.0" encoding="UTF-8"?> 
<kml xmlns="http://earth.google.com/kml/2.0" xmlns:ns="urn:oasis:names:tc:ciq:xsdschema:xAL:2.0"> 
    <Response> 
     <Placemark> 
      <ns:AddressDetails> 
       <ns:Country> 
        <ns:CountryNameCode>US</ns:CountryNameCode> 
        <ns:AdministrativeArea> 
         <ns:AdministrativeAreaName>CA</ns:AdministrativeAreaName> 
         <ns:SubAdministrativeArea> 
          <ns:Locality> 
           <ns:LocalityName>Mountain View</ns:LocalityName> 
           <ns:Thoroughfare> 
            <ns:ThoroughfareName>1600 Amphitheatre Pkwy</ns:ThoroughfareName> 
           </ns:Thoroughfare> 
           <ns:PostalCode> 
            <ns:PostalCodeNumber>94043</ns:PostalCodeNumber> 
           </ns:PostalCode> 
          </ns:Locality> 
         </ns:SubAdministrativeArea> 
        </ns:AdministrativeArea> 
       </ns:Country> 
      </ns:AddressDetails> 
     </Placemark> 
    </Response> 
</kml>
