如何使用 Java 将自定义字段添加到 Salesforce 中的现有对象

Question

我想将一个外部 id 字段添加到一个还没有它的对象。

我需要什么：

• 连接到销售团队。
• 获取可用对象。
• 获取每个对象的字段。
• 检查其中一个字段是否是每个对象的外部 ID。

我需要它做什么：

• 如果外部 id 字段不存在：为此对象创建它。
• 在我的进程（迁移进程）结束时删除它的另一种方法。

以下代码用于连接到 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。

这是我目前编写的代码：

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？

Answer 1

经过多次尝试和失败，我终于有了我的问题的答案。

在连接try/catch中，更新如下代码：

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要查找的字段是否存在，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，如果组织中的对象尚不存在，我们就会为它创建一个自定义字段。

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。希望对您有所帮助。
