使用JaxB解析XML的空響應

Question

我如何使用Jaxb解析XML。

<?xml version="1.0" encoding="utf-8"?> 
    <string xmlns="http://www.xyz.in"><root><Del><NUMBER>13691991</NUMBER><PIECES>2</PIECES><SHEETNO>D1415/001005</SHEETNO></Del></root></string> 

Answer 1

嘗試創建這些類：

類德爾

package jaxb; 
import javax.xml.bind.annotation.XmlAccessType; 
import javax.xml.bind.annotation.XmlAccessorType; 
import javax.xml.bind.annotation.XmlElement; 
import javax.xml.bind.annotation.XmlRootElement; 

@XmlAccessorType(XmlAccessType.FIELD) 
@XmlRootElement(name = "Del") 
public class Del { 
@XmlElement(name = "NUMBER") 
private String number; 
@XmlElement(name = "PIECES") 
private String pieces; 
@XmlElement(name = "SHEETNO") 
private String sheetno; 
public Del() { 
    super(); 
} 

public void setNumber(String number) { 
    this.number = number; 
} 

public String getNumber() { 
    return number; 
} 

public void setPieces(String pieces) { 
    this.pieces = pieces; 
} 

public String getPieces() { 
    return pieces; 
} 

public void setSheetno(String sheetno) { 
    this.sheetno = sheetno; 
} 

public String getSheetno() { 
    return sheetno; 
} 
} 

類MyString的

package jaxb; 
import javax.xml.bind.annotation.XmlAccessType; 
import javax.xml.bind.annotation.XmlAccessorType; 
import javax.xml.bind.annotation.XmlElement; 
import javax.xml.bind.annotation.XmlRootElement; 

@XmlAccessorType(XmlAccessType.FIELD) 
@XmlRootElement(name = "string") 
public class MyString { 
    @XmlElement(name = "root") 
    private Root root; 

    public MyString() { 
     super(); 
    } 

    public void setRoot(Root root) { 
     this.root = root; 
    } 

    public Root getRoot() { 
     return root; 
    } 
} 

的R級OOT

package jaxb; 
import javax.xml.bind.annotation.XmlAccessType; 
import javax.xml.bind.annotation.XmlAccessorType; 
import javax.xml.bind.annotation.XmlElement; 
import javax.xml.bind.annotation.XmlRootElement; 

@XmlAccessorType(XmlAccessType.FIELD) 
@XmlRootElement(name = "root") 
public class Root { 
    @XmlElement(name = "Del") 
    private Del del; 

    public Root() { 
     super(); 
    } 

    public void setDel(Del del) { 
     this.del = del; 
    } 

    public Del getDel() { 
     return del; 
    } 
} 

文件package-info.java

@XmlSchema(namespace="http://www.xyz.in", 
      xmlns={ @XmlNs(prefix = "", namespaceURI = "http://www.xyz.in")}, 
       elementFormDefault = XmlNsForm.QUALIFIED) 

package jaxb; 

import javax.xml.bind.annotation.XmlNs; 
import javax.xml.bind.annotation.XmlNsForm; 
import javax.xml.bind.annotation.XmlSchema; 

**主類測試**

package jaxb; 

import java.io.StringReader; 

import javax.xml.bind.JAXBContext; 
import javax.xml.bind.JAXBException; 
import javax.xml.bind.Unmarshaller; 

public class Main { 

    public static void main(String[] args){ 
     try { 
      String file = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" + 
      "<string xmlns=\"http://www.xyz.in\">\n" + 
      " <root>\n" + 
      "  <Del>\n" + 
      "   <NUMBER>13691991</NUMBER>\n" + 
      "   <PIECES>2</PIECES>\n" + 
      "   <SHEETNO>D1415/001005</SHEETNO>\n" + 
      "  </Del>\n" + 
      " </root>\n" + 
      "</string>"; 
      JAXBContext jaxbContext = JAXBContext.newInstance(MyString.class); 
      Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller(); 
      StringReader reader = new StringReader(file); 
      MyString myString = (MyString)jaxbUnmarshaller.unmarshal(reader); 
      System.out.println(myString); 

     } catch (JAXBException e) { 
      e.printStackTrace(); 
     } 
    } 
}
