红帽全球峰会289.12. 使用 Salesforce Composite API 提交多个链请求
复合 操作允许提交最多 25 个请求，这些请求可以串联在一起，以便在后续请求中使用之前生成的实例标识符。单个请求和响应与提供的 参考链接。
注意
复合 API 仅支持 JSON 有效负载。
注意
与批处理 API 一样，结果可能会因 API 而异，因此请求的结果会被指定为 java.lang.Object。在大多数情况下，结果将是 java.util.Map，带有字符串键和值或其他 java.util.Map 作为值。以 JSON 格式发出的请求保存了一些类型信息（即，知道哪个值是字符串以及哪些值是数字），因此通常它们会更友好。
让我们来看一个示例：
SObjectComposite composite = new SObjectComposite("38.0", true);
// first insert operation via an external id
final Account updateAccount = new TestAccount();
updateAccount.setName("Salesforce");
updateAccount.setBillingStreet("Landmark @ 1 Market Street");
updateAccount.setBillingCity("San Francisco");
updateAccount.setBillingState("California");
updateAccount.setIndustry(Account_IndustryEnum.TECHNOLOGY);
composite.addUpdate("Account", "001xx000003DIpcAAG", updateAccount, "UpdatedAccount");
final Contact newContact = new TestContact();
newContact.setLastName("John Doe");
newContact.setPhone("1234567890");
composite.addCreate(newContact, "NewContact");
final AccountContactJunction__c junction = new AccountContactJunction__c();
junction.setAccount__c("001xx000003DIpcAAG");
junction.setContactId__c("@{NewContact.id}");
composite.addCreate(junction, "JunctionRecord");
final SObjectCompositeResponse response = template.requestBody("salesforce:composite?format=JSON", composite, SObjectCompositeResponse.class);
final List<SObjectCompositeResult> results = response.getCompositeResponse();
final SObjectCompositeResult accountUpdateResult = results.stream().filter(r -> "UpdatedAccount".equals(r.getReferenceId())).findFirst().get()
final int statusCode = accountUpdateResult.getHttpStatusCode(); // should be 200
final Map<String, ?> accountUpdateBody = accountUpdateResult.getBody();
final SObjectCompositeResult contactCreationResult = results.stream().filter(r -> "JunctionRecord".equals(r.getReferenceId())).findFirst().get()
SObjectComposite composite = new SObjectComposite("38.0", true);
// first insert operation via an external id
final Account updateAccount = new TestAccount();
updateAccount.setName("Salesforce");
updateAccount.setBillingStreet("Landmark @ 1 Market Street");
updateAccount.setBillingCity("San Francisco");

updateAccount.setIndustry(Account_IndustryEnum.TECHNOLOGY);
composite.addUpdate("Account", "001xx000003DIpcAAG", updateAccount, "UpdatedAccount");
