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：
