利用java开发ASN.1

   最近做电信预付费用户话单（ASN.1格式），由于需求比较急，客户要求尽快搞定。这几天忙的焦头烂额，几乎把google上能查到的asn1相关信息都试了一下，今天终于有了一点成就，并生成了个测试话单……

   初次尝试：

  （Java Asn1 Compiler（JAC））：由于只支持tag值 1-127，所以放弃

  例子：

/**
 * 话单头部
 * @author mizhao
 *
 */
public class HeaderNode extends Sequence {
 
 /**
  * 记录类型
  */
 IA5String recordType = new IA5String("recordType");
 /**
  * 拜访局代码
  */
 IA5String visitBureauCode = new IA5String("visitBureauCode");
 
 /**
  * 归属局代码
  */
 IA5String belongBureauCode = new IA5String("belongBureauCode");
 
 /**
  * 文件序号
  */
 IA5String serialNo = new IA5String("serialNo");
 
 /**
  * 文件产生日期（YYYYMMDDHHMISS）
  */
 IA5String createDate = new IA5String("createDate");
 
 /**
  * 文件版本号
  */
 IA5String versionNo = new IA5String("versionNo");
 
 public HeaderNode(){
  super();
  setUpElements();
 }
 
 public HeaderNode(String name){
  super(name);
  setUpElements();
 }
 
 protected void setUpElements() {
  super.addElement(recordType);
  recordType.setTagClass(Tag.APPLICATION);
  recordType.setTagNumber(ASN1TagConstants.TAG_RECORD_TYPE);
  super.addElement(visitBureauCode);
  visitBureauCode.setTagClass(Tag.APPLICATION);
  visitBureauCode.setTagNumber(ASN1TagConstants.TAG_VISIT_BUREAU_CODE);
  super.addElement(belongBureauCode);
  belongBureauCode.setTagClass(Tag.APPLICATION);
  belongBureauCode.setTagNumber(ASN1TagConstants.TAG_BELONG_BUREAU_CODE);
  super.addElement(serialNo);
  serialNo.setTagClass(Tag.APPLICATION);
  serialNo.setTagNumber(ASN1TagConstants.TAG_SERIAL_NO);
  super.addElement(createDate);
  createDate.setTagClass(Tag.APPLICATION);
  createDate.setTagNumber(ASN1TagConstants.TAG_CREATE_DATE);
  super.addElement(versionNo);
  versionNo.setTagClass(Tag.APPLICATION);
  versionNo.setTagNumber(ASN1TagConstants.TAG_VERSION_NO);
 }

}

测试方法：

//create header
  headerNode.recordType.setValue("10");
  headerNode.visitBureauCode.setValue("46003114");
  headerNode.belongBureauCode.setValue("46003114");
  headerNode.serialNo.setValue("1");
  headerNode.createDate.setValue("20100817142800");
  headerNode.versionNo.setValue("10");

 

  ByteArrayOutputStream stream = new ByteArrayOutputStream();  
  BerOutputStream out = new BerOutputStream(stream);
  headerNode.encode(out);
  byte[] bytes = stream.toByteArray();

   …………

   最终定稿：

   bouncycastle：

 /**

}

  

注：ASN1TagConstants中的常量可以自定义

测试方法：

public static BillingRecord createData(String servedNum,String userType,String callingType,String callingMeans,String callingNum,String calledNum
   ,String callBeginTime,String callStopTime,String callDuration,int createCycleQuantity,String cycleAttr,String spCode
   ,String chargeType,int fee,int discount){
  BillingRecord billingRecord = new BillingRecord(servedNum, userType, callingType, callingMeans, callingNum, calledNum, callBeginTime, callStopTime, callDuration, createCycleQuantity, cycleAttr, spCode, chargeType, fee, discount);
  return billingRecord;
 }

 

public static void main(String[] args) throws Exception {
    //数据信息(功能费)
  BillingRecord billingRecord = createData("13379035182","1","20","1","13379035182","1188913379035182","20100817142800","20100817142800","0",1,"1","10659181","2",5000,0);
  
 
//  ByteArrayOutputStream bOut = new ByteArrayOutputStream();
//  DEROutputStream dOut = new DEROutputStream(bOut);
//  dOut.writeObject(billingRecord );
//  byte[] bytes = bOut.toByteArray();

 }
