- 注解方式语义清晰，适合终端系统对报文进行处理；
- YAML/XML文件具有动态加载功能，工具包提供在线刷新方法，可手动触发或与第三方配置中心服务集成，可以做到配置热更新； 所以YAML/XML方式适合交易转发类应用，修改配置无需重启；
- 相对与YAML，XML可以通过schema增强校验，减少配置出错的概率；
- 数据库配置方式同YAML/XML文件配置方式优势基本相同，但数据库方式语义更强，配置更灵活；可以同后台管理系统集成，通过页面进行维护。
注：四种配置方式可以同时使用，针对同一报文配置项，先加载会被后加载的覆盖。
YAML/XML/数据库配置方式通过调用MessageDefinitionBuilder#refresh()方法，实现配置在线刷新；注解方式不支持在线刷新。
注：在线刷新时可能会导致报文解析过程出现中间状态，建议通过应用层面解决（比如灰度发布），后续版本考虑优化该问题。
前文提到YAML/XML方式对应自定义容器MessageHolder，注解方式对应其配置POJO；以上为默认映射关系，特殊场景下可手动进行变换。
alatka.messages:
remark: 明细查询
type: fixed
group: "0395"
code: 3116
holder:
request: com.xxx.yyy.POJO1
response: com.xxx.yyy.POJO2
subPayload:
F13: com.xxx.yyy.POJO3
.....<request clazz="com.xxx.yyy.POJO1">
......
</request>
<response clazz="com.xxx.yyy.POJO2">
......
</response>
<subPayload domain="F13" clazz="com.xxx.yyy.POJO3">
......
</subPayload>ALK_MESSAGE_DEFINITION
| M_ID | M_TYPE | M_GROUP | M_CODE | M_KIND | M_DOMAIN | M_USAGE | M_DOMAIN_TYPE | M_HOLDER | M_CHARSET | M_REMARK |
|---|---|---|---|---|---|---|---|---|---|---|
| 3 | fixed | 0395 | 3116 | request | NONE | com.xxx.yyy.POJO1 | GB18030 | 明细查询请求报文 | ||
| 4 | fixed | 0395 | 3116 | response | NONE | com.xxx.yyy.POJO2 | GB18030 | 明细查询应答报文 | ||
| 5 | fixed | 0395 | 3116 | subPayload | F13 | NONE | com.xxx.yyy.POJO3 | GB18030 | 明细查询应答分页子域 |
注：POJO字段名称及java类型需要与YAML/XML/数据库配置中一一对应。
@MessageMeta(
type = MessageDefinition.Type.fixed,
group = "0395",
code = "3116",
kind = MessageDefinition.Kind.response,
customize = true, // true: MessageHolder, false: 当前POJO
remark = "明细查询")
public class Fixed3006Res extends FixedHeader {
@FixedFieldMeta(domainNo = 8, length = 19, remark = "卡号")
private String cardNbr;
// getter setter
}前置类系统转发交易数据，一般只需解析个别域，大部分域是不处理原样转发；
针对无需解析的域，一般的处理方式是将该域的class属性配置为byte[]，这样可以省去java类型映射转换的操作，但变长域的场景下，仍然需要对长度域进行处理；
如果变长域也不需要处理，可以配置该域的status属性为RAW；注：配置status = RAW后该域的class属性不再生效，域值将以byte[]形式进行存储。
对接外卡组织的前置系统，一般涉及到EBCDIC码、BCD码、ASCII码、HEX相互转换；以对接JCB为例，该场景下可做如下配置：
对接外卡组织jcb.common.iso.ymlYAML文件：
......
- { "domainNo": 2, "name": "pan", "fixed": false, "length": 1, "maxLength": 10, "remark": "主账号", "clazz": "java.lang.String", "parseType": "BCD" }
- { "domainNo": 3, "name": "processingCode", "fixed": true, "length": 3, "remark": "交易处理码", "clazz": "java.lang.String", "parseType": "BCD" }
- { "domainNo": 4, "name": "amtTrans", "fixed": true, "length": 6, "remark": "交易金额", "clazz": "java.math.BigDecimal", "parseType": "BCD" }
......
- { "domainNo": 37, "name": "retrivlRefNum", "fixed": true, "length": 12, "remark": "检索参考号", "clazz": "java.lang.String", "parseType": "EBCDIC" }
- { "domainNo": 38, "name": "authrIdResp", "fixed": true, "length": 6, "remark": "授权标识应答码", "clazz": "java.lang.String", "parseType": "EBCDIC" }
......对接行内jcb.bank.iso.ymlYAML文件：
......
- { "domainNo": 2, "name": "pan", "fixed": false, "length": 2, "maxLength": 19, "remark": "主账号", "clazz": "java.lang.String" }
- { "domainNo": 3, "name": "processingCode", "fixed": true, "length": 6, "remark": "交易处理码", "clazz": "java.lang.String" }
- { "domainNo": 4, "name": "amtTrans", "fixed": true, "length": 12, "remark": "交易金额", "clazz": "java.math.BigDecimal" }
......
- { "domainNo": 37, "name": "retrivlRefNum", "fixed": true, "length": 12, "remark": "检索参考号", "clazz": "java.lang.String" }
- { "domainNo": 38, "name": "authrIdResp", "fixed": true, "length": 6, "remark": "授权标识应答码", "clazz": "java.lang.String" }
......jcb发送行内的交易
byte[] unpack = ...; // jcb->前置的交易报文
MessageHolder holder = MessageBuilder.init("iso:jcb:common:payload").unpack(unpack); // 解包为MessageHolder
MessageHolder holder1 = holder.copyOf("iso:jcb:bank:payload"); // MessageHolder复制
byte[] pack = MessageBuilder.init("iso:jcb:bank:payload").pack(holder1); //前置->行内的交易报文打包行内发送jcb的交易
byte[] unpack = ...; // 行内->前置的交易报文
MessageHolder holder = MessageBuilder.init("iso:jcb:bank:payload").unpack(unpack); // 解包为MessageHolder
MessageHolder holder1 = holder.copyOf("iso:jcb:common:payload"); // MessageHolder复制
byte[] pack = MessageBuilder.init("iso:jcb:common:payload").pack(holder1); //前置->jcb的交易报文打包MessageBuilder除了解析完整8583/固定格式报文以外，还可以单独解析8583某一子域；
MessageBuilder.init("iso:cups:common:subPayload:F55").unpack(bytes); // 银联55域
MessageBuilder.init("iso:cups:common:subPayload:F48:IN").unpack(bytes); // 银联48域usage=IN
MessageBuilder.init("iso:cups:common:subPayload:F60_F11").unpack(bytes); // 银联60.11域
MessageBuilder.init("iso:cups:common:subPayload:F59$QR_F3").unpack(bytes); // 银联59域usage=QR F3子域注：不能单独解析分页子域和不定长子域。
工具包提供完善的错误信息日志及跟踪日志，方便线上问题跟踪和线下debug。
针对打包解包功能，提供精确到具体域的报错信息，例如：
- 银联48域未配置子域usage=ON

}针对注解配置，使用POJO作为数据容器的场景，可以使用MessageHolder#fromPojo(Object)方法，将POJO转换为MessageHolder，然后再格式化输出。
alatka-messages及其相关制品已上传至阿里云仓库，如需下载可进行如下配置：
1.设置仓库凭证
在 settings.xml 文件中设置以下仓库的访问凭证。
<servers>
<server>
<id>2448467-release-d4LMO3</id>
<username>661f7b16a0522beff388bd5c</username>
<password>R06ilmt)Ii=j</password>
</server>
</servers>2.配置仓库和包信息
在settings.xml文件节点中加入对应的仓库使用地址。

每个报文域对应一个FieldDefinition对象，随着报文接口的增多，jvm内存开销线性增加；在接口较多的场景下，内存开销问题不容忽视。
TODO
- 报文域类型不支持java原始类型（int/byte/long/short/boolean...）：原始类型有默认值，会影响报文域取值和赋值；
- TODO
