项目实践：客户域和账户域服务在应用层的编排

上面已经分别实现了客户域和账户域服务的开发和部署，在应用层中，能方便地对域服务进行服务编排。
在xbank-app模块中，我们可以在PersonalAppService类中，方便地进行服务编排，代码如下：

@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 CustomerAndAccountList getCustomerAndAccountList(String customerId) {
        Customer customer = this.customerSinkInterface.getCustomer(customerId);
        List<Account> accountList = this.accountSinkInterface.getAccountListByCustomerId(customerId);
        CustomerAndAccountList customerAndAccountList = new CustomerAndAccountList();
        customerAndAccountList.setCustomer(customer);
        customerAndAccountList.setAccountList(accountList);
        return customerAndAccountList;
    }
...
}

在getCustomerAndAccountList()方法中，我们可以同时调用客户域的接口customerSinkInterface，也可以调用账户域的接口accountSinkInterface，从而实现多个域服务的混合编排。
这个聚合服务通过bean-service进行部署：

，分别支持Biz-SIP开放平台接口访问和个性化的PersonController实现的REST接口：

• 通过Biz-SIP开放平台接口测试：

$ curl -H "Content-Type:application/json" -H "Biz-Service-Id:app/personal" -X POST --data '{"methodName":"getCustomerAndAccountList","params":["001"]}' http://localhost:8888/api|jq

{
  "code": 0,
  "message": "success",
  "extMessage": null,
  "traceId": "c3cda0e1b95f449e986dc5ee41e48716",
  "parentTraceId": null,
  "timestamp": 1630760469452,
  "data": {
    "result": {
      "accountList": [
        {
          "accountId": "0001",
          "balance": 100,
          "customerId": "001"
        },
        {
          "accountId": "0002",
          "balance": 200,
          "customerId": "001"
        }
      ],
      "customer": {
        "sex": "1",
        "customerName": "张三",
        "customerId": "001",
        "age": 30
      }
    }
  }
}

• 通过个性化PersonController实现的REST接口，接口测试如下：

$ curl http://localhost:9001/personal/getCustomerAndAccountList\?customerId=001|jq

{
  "customer": {
    "customerId": "001",
    "customerName": "张三",
    "age": 30,
    "sex": "1"
  },
  "accountList": [
    {
      "accountId": "0001",
      "customerId": "001",
      "balance": 100
    },
    {
      "accountId": "0002",
      "customerId": "001",
      "balance": 200
    }
  ]
}
