如果可能的话，有人可以指导我朝着正确的方向前进吗？第二个代码（Batch Apex）只是没有编译。目前的错误是，

Error: Compile Error: Invalid type: updateContactOnEmailOptOutChangeScheduler
                      at line 63 column 73

但我认为还有其他问题我似乎无法解决。

在联系人更新时，如果此字段已更新，则触发器会使用“电子邮件退出”的新值更新所有重复的联系人。此外，触发器仅更新具有HasOptedOutOfEmail与正在更新的值不同的值的重复联系人。现在我的任务是将这个需求从触发器（由我的同事编写和测试）转换为 Batch Apex。首先是原始触发器。二是我刚才写的batch apex格式的代码。

原始触发代码

trigger updateContactOnEmailOptOutChange on Contac​t (after update) {                                ​                                                  ​        

//Initialize lists and maps

List<Contact> duplicateContacts = new List<Con​tact>();
Map<String, Contact> contactEmailMap = new Map​&lt;String, Contact>();
Map<Id, Contact> contactIdMap = new Map<Id, Co​ntact>();

//Build a map with contacts to update. Only se​lect the ones that have a different "Email Opt Out​" value from the contact being updated.

for (Integer i = 0; i < Trigger.new.size(); i+​+) {
    if (Trigger.old[i].HasOptedOutOfEmail != T​rigger.new[i].HasOptedOutOfEmail) {
        contactEmailMap.put(Trigger.old[i].ema​il, Trigger.new[i]);
        contactIdMap.put(Trigger.old[i].id, Tr​igger.new[i]);        
    }
}    

//Only go through this process if "Email Opt O​ut" (HasOptedOutofEmail) was updated.

If (contactIdMap.size()>0) {

    //Query the database and look for all cont​acts with a duplicate email address (same email as​ the contact currently being updated).

    for (Contact dupContact : [SELECT Id, Name​, Email, HasOptedOutOfEmail
                               FROM Contact
                               WHERE Email IN ​: contactEmailMap.KeySet()
                               AND Id NOT IN :​ contactIdMap.KeySet()]) {
        Contact contact = contactEmailMap.get(​dupContact.Email);
        If (dupContact.HasOptedOutOfEmail <> c​ontact.HasOptedOutOfEmail) { 
            dupContact.HasOptedOutOfEmail = co​ntact.HasOptedOutOfEmail;   
            duplicateContacts.add(dupContact);
        }
    }    

    //If any duplicate contacts were found, up​date all duplicate contacts with the new HasOptedO​utOfEmail value.

   If (duplicateContacts.size()>0) update dupl​icateContacts;
}
}

您的批处理顶点包括对仅在触发器内有效的 Trigger 类的引用。编译错误消息说第 63 行存在无效类型。检查行号，但这可能指向对触发器的引用
