xmlBean学习二

由上一遍的准备工作完成后,可以很简单的就进行对xml文件的操作,

package com;

import java.io.File;
import java.io.IOException; import org.apache.xmlbeans.XmlException; import sample.xmlbean.AddressType;
import sample.xmlbean.BillingAddressType;
import sample.xmlbean.CustomerType;
import sample.xmlbean.CustomersDocument;
import sample.xmlbean.CustomersDocument.Customers;
import sample.xmlbean.PrimaryAddressType; public class CustomerXMLBean { private String fileName=null;
public CustomerXMLBean(String fileName){
this.fileName=fileName;
}
/**
* 读取xml文件
*/
public void customerReader(){
File file = new File(fileName);
try {
CustomersDocument document = CustomersDocument.Factory.parse(file);
Customers customers = document.getCustomers();
//System.out.println(customers);
CustomerType[] types = document.getCustomers().getCustomerArray();
for(CustomerType customer:types){
System.out.println(customer.getId());
System.out.println(customer.getGender());
System.out.println(customer.getFirstname()+" "+customer.getLastname());
System.out.println(customer.getPhoneNumber());
AddressType address = customer.getAddress();
//System.out.println(address);
PrimaryAddressType primaryAddress = address.getPrimaryAddress();
BillingAddressType billingAddress = address.getBillingAddress();
System.out.println("---------primaryAddress----------");
System.out.println(primaryAddress.getAddressLine1());
System.out.println(primaryAddress.getAddressLine2());
System.out.println(primaryAddress.getPostalCode());
System.out.println("---------billingAddress----------");
System.out.println(billingAddress.getReceiver());
System.out.println(billingAddress.getPostalCode());
System.out.println(billingAddress.getAddressLine1());
}
} catch (XmlException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
/**

/*//创建document
CustomersDocument doc = CustomersDocument.Factory.newInstance();
//添加customer
CustomerType customer = doc.addNewCustomers().addNewCustomer();
customer.setId(3);

try{
// Create Document<br />

// set customer info<br />

/**

public void addNewCustomer() {

System.out.println(customer.documentProperties()+"~~~~~~~~~");

primaryAddress.setAddressLine2("302");
//保存
doc.save(xmlFile);
} catch (Exception ex) {
ex.printStackTrace();
}
} /**

public void deleteCustomer(){
File file = new File(fileName);
try {
CustomersDocument doc = CustomersDocument.Factory.parse(file);
CustomerType[] customers = doc.getCustomers().getCustomerArray();
for (int i = 0; i < customers.length; i++) {
CustomerType customer = customers[i];
if(customer.getId()==3){
customer.setNil() ;
break;
}
}
doc.save(file);
} catch (XmlException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} }
public static void main(String[] args) {
// TODO Auto-generated method stub
CustomerXMLBean b = new CustomerXMLBean("E:\\code\\workspace\\XmlBean\\customers.xml");
CustomerXMLBean b1 = new CustomerXMLBean("E:\\code\\workspace\\XmlBean\\customers1.xml");
b1.createCustomer();
//b.addNewCustomer();
b.deleteCustomer();
b1.customerReader();
b.customerReader(); }

以上代码除了删除的以外都可以运行出来,唯独删除,出错,报了以下异常:

Exception in thread "main" org.apache.xmlbeans.impl.values.XmlValueNotNillableException
at org.apache.xmlbeans.impl.values.XmlObjectBase.setNil(XmlObjectBase.java:624)
at com.CustomerXMLBean.deleteCustomer(CustomerXMLBean.java:167)
at com.CustomerXMLBean.main(CustomerXMLBean.java:187)

经过我反编译通过上篇使用scomp生成的jar包,发现接口中定义的setNil()方法并没有被实现重写,暂时没有想出问题出在哪,或许可能因为使用的xmlBean的版本太低导致,假如有读者也遇到问题,可以联系我,讨论一下,找出解决方法。
