我想将一个External id字段添加到一个尚未拥有它的对象中。
我需要什么：
我需要做什么：
以下代码用于连接salesforce org：
ConnectorConfig PartnerCfg = new ConnectorConfig();
PartnerCfg.setUsername(USERNAME);
PartnerCfg.setPassword(PASSWORD);
try {
myConnection = com.sforce.soap.partner.Connector.newConnection(PartnerCfg);
} catch (ConnectionException e) {
System.out.println("An error occured while connecting to the org.");
}
假设“Fields”是每个对象的字段数组，EXT_ID__C是包含“Ext_Id__c”字符串的常量。
这是我到目前为止所做的代码：
customFieldExists = false;
for (int j = 0; j < fields.length; j++) {
Field field = fields[j];
if ("customField__c".equals(field.getName())) {
customFieldExists = true;
}
// If field is the last of the object
if (j == fields.length - 1) {
if (customFieldExists == false) {
CustomField customField = new CustomField();
customField.setFullName(EXT_ID__C);
customField.setLabel("Ext_Id");
customField.setType(FieldType.Text);
customField.setExternalId(true);
customField.setLength(18);
// Here Should come the code to upload the field and its properties
// To salesforce org current object.
System.out.println("Created customField__c field in object " + ObjectName);
}
}
}
如何将extId自定义字段推送到我的组织？

经过多次尝试并失败后，我终于回答了我的问题。
在连接try / catch中，更新以下代码：
try {
myConnection = com.sforce.soap.partner.Connector.newConnection(PartnerCfg);
metadataCfg.setSessionId(trgtConnection.getSessionHeader().getSessionId());
metadataConnection = com.sforce.soap.metadata.Connector.newConnection(metadataCfg);
} catch (ConnectionException e) {
System.out.println("An error occured while connecting to the org.");
}
然后，以下代码遍历每个对象以检查我们正在寻找的字段是否存在，如果不存在，则创建它。假设sObjects变量是一个sObjects数组。
DescribeSObjectResult[] objects = myConnection.describeSObjects(sObjects);
for (int i = 0; i < objects.length; i++) {
// object #i is stored in desObj variable.
DescribeSObjectResult desObj = objects[i];
// Get the name of the sObject
String objectName = desObj.getName();
boolean customFieldExists = false;
// Iterate through the fields to get properties of each field
for (int j = 0; j < fields.length; j++) {
Field field = fields[j];
if ("customField__c".equals(field.getName())) {
extIdExists = true;
}
// If field is the last of the object
if (j == fields.length - 1) {
// Create a new custom field
CustomField customField = new CustomField();
// Add its properties to the custom field
customField.setFullName(objectName + "." + customField__c);
customField.setLabel("customField");
customField.setType(FieldType.Text);
customField.setExternalId(true);
customField.setLength(18);
// Push it to the object
metadataConnection.create(new Metadata[] {customField});
System.out.println("Created customField__c field in object " + objectName);
}
}
}
这样，我们就为组织中的对象创建一个自定义字段（如果它尚不存在）。
可以根据用例以各种方式修改和使用它来创建多个自定义字段。希望它可以提供帮助。
