Project practice: assembly of application services to deferred services
1. Implementation of SAF store and forward
In the domain layer, Payment2SinkService is developed to handle various exceptions such as timeout, failure and success according to the tranMode transaction mode:
@Service
public class Payment2SinkService implements JSONObjectSinkBeanInterface {
@Autowired
private TimeoutCmdExe timeoutCmdExe;
@Autowired
private TimeoutAndFailCmdExe timeoutAndFailCmdExe;
@Autowired
private TimeoutAndSuccessCmdExe timeoutAndSuccessCmdExe;
@Autowired
private SuccessCmdExe successCmdExe;
@Override
public JSONObject process(JSONObject jsonObject) throws BizException {
log.info("incoming message :\n{}", jsonObject.toString());
AbstractSinkBeanCmdExe sinkBeanCmdExe;
String tranMode = (String)jsonObject.get("tranMode");
switch (tranMode) {
case "timeout":
// After receiving the transaction, the timeout is always returned
return timeoutCmdExe.execute(jsonObject);
case "3timeout-fail":
// After receiving the transaction, the first 3 times of return timeout and the fourth time of return failure code
return timeoutAndFailCmdExe.execute(jsonObject);
case "3timeout-success":
// After receiving the transaction, the first three returns timeout, and the fourth successfully returns the original message
return timeoutAndSuccessCmdExe.execute(jsonObject);
default:
//In other cases, the original message is returned successfully
return successCmdExe.execute(jsonObject);
}
}
}
Note that the encapsulation of the Payment2 domain service involves multiple interface calls. The Command Executor is used for each interface. Here, the standard JSONObject data is passed in, so all interface implementations inherit the AbstractSinkBeanCmdExe class:
In the application layer, send2Payment2() and getCustomerAndSaf2Payment2() method interfaces and implementations are added to the original personalapppinterface application layer interface and PersonalAppService service class. Multiple SAF calls to the original send2Payment2() method are realized through the personalAppDelayInterface delay call interface:
@Service
public class PersonalAppService implements PersonalAppInterface {
...
private BizMessageInterface payment2SinkInterface = IntegratorClientFactory
.getSinkClient(BizMessageInterface.class,"payment2-sink");
private PersonalAppInterface personalAppDelayInterface = IntegratorClientFactory
.getDelayBizServiceClient(PersonalAppInterface.class,"app/personal",
0,1000,2000,4000,8000,16000,32000);
...
@Override
public BizMessage send2Payment2(String tranMode, String tranCode, Object message) throws BizException {
JSONObject jsonObject = new JSONObject();
jsonObject.set("tranCode",tranCode);
jsonObject.set("tranMode",tranMode);
jsonObject.set("message",message);
return this.payment2SinkInterface.call(jsonObject);
}
@Override
public Customer getCustomerAndSaf2Payment2(String tranMode,String customerId) throws BizException {
Customer customer = this.customerSinkInterface.getCustomer(customerId);
this.personalAppDelayInterface.send2Payment2(tranMode,"send-customer", customer);
return customer;
}
...
}
The incoming transaction mode is "timeout" (always return timeout after receiving the transaction), which will lead to 7 times of sending, and the final transaction status is failed:
$ curl -H "Content-Type:application/json" -H "Biz-Service-Id:app/personal" -X POST --data '{"methodName":"getCustomerAndSaf2Payment2","params":["timeout","001"]}' http://localhost:8888/api|jq

2. Realization of forward compensation
The forward compensation mechanism means that when there is no response to the transaction, the system will query the original transaction. If the query times out, it will be retried multiple times. If the original transaction succeeds, the subsequent transaction will continue. If the original transaction fails, the transaction compensation will be made to the previous transaction. Forward compensation is generally a solution for the third-party recipient who cannot provide compensation transactions.
In the financial field, this kind of transaction compensation action is often called "reversal".
In the application layer, payoutForward() and payoutForwardCompensate() method interfaces and implementations are added to the original personalapppinterface application layer interface and PersonalAppService service class. Multiple repeated delayed calls to the original payoutForwardCompensate() method are realized through the personalAppDelayInterface delayed call interface:
@Service
public class PersonalAppService implements PersonalAppInterface {
private AccountSinkInterface accountSinkInterface = IntegratorClientFactory
.getSinkClient(AccountSinkInterface.class,"account-sink");
private CustomerSinkInterface customerSinkInterface = IntegratorClientFactory
.getSinkClient(CustomerSinkInterface.class,"customer-sink");
private BizMessageInterface payment1SinkInterface = IntegratorClientFactory
.getSinkClient(BizMessageInterface.class,"payment1-sink");
private BizMessageInterface payment2SinkInterface = IntegratorClientFactory
.getSinkClient(BizMessageInterface.class,"payment2-sink");
private PersonalAppInterface personalAppDelayInterface = IntegratorClientFactory
.getDelayBizServiceClient(PersonalAppInterface.class,"app/personal",
0,1000,2000,4000,8000,16000,32000);
......
@Override
public void payoutForward(String tranMode,String accountId, long amount) throws BizException {
log.info("account Out of gold:{},{}",accountId,amount);
this.accountDomainInterface.payout(accountId,amount);
JSONObject jsonObject = new JSONObject();
jsonObject.set("tranCode","pay");
jsonObject.set("tranMode",tranMode);
jsonObject.set("accountId",accountId);
jsonObject.set("tranAmount",amount);
BizMessage<JSONObject> bizMessage = null;
try {
log.info("payment pay...");
bizMessage = this.payment2SinkInterface.call(jsonObject);
} catch (BizException e) {
if (e.isTimeOutException()) {
log.info("payment Transaction timeout,start payout compensate...");
this.personalAppDelayInterface.payoutForwardCompensate(jsonObject);
return;
}
else {
throw e;
}
}
log.info("payment Payment succeeded!");
log.info("payout success!");
}
@Override
public void payoutForwardCompensate(JSONObject jsonObject) throws BizException{
jsonObject.set("tranCode","pay-query");
BizMessage<JSONObject> bizMessage = null;
try {
log.info("payment Query payment order...");
bizMessage = this.payment2SinkInterface.call(jsonObject);
} catch (BizException e) {
if (e.isTimeOutException()) {
log.info("payment Transaction timeout...");
throw e;
}
else {
log.info("payment Error returned from querying payment order (indicating that the opposite order has not been executed)...");
String accountId = (String)jsonObject.get("accountId");
long amount = (Integer) jsonObject.get("tranAmount");
log.info("account Payment compensation:{},{}",accountId,amount);
this.accountDomainInterface.payoutCompensation(accountId,amount);
return;
}
}
log.info("payment Successful query of payment order (indicating that the opposite order has been executed)");
log.info("payout success!");
}
The incoming transaction mode is "3timeout success" (after receiving the order transaction, the first three times will return timeout, and the fourth time will return simulation that the order has been executed). This will lead to four times of sending, and the final transaction status is success:
$ curl -H "Content-Type:application/json" -H "Biz-Service-Id:app/personal" -X POST --data '{"methodName":"payoutForward","params":["3timeout-success","0001",1]}' http://localhost:8888/api|jq
