如何通過 Mongock 向集合中的所有文檔添加新字段？

Question

我有一個文檔集合，如下所示：

[
    {
        "firstName" : "Foo",
        "phone" : "+1 111 1111",
        "car": "Toyota"
    },
    {
        "firstName" : "Bar",
        "phone" : "+2 222 2222",
        "car": "Honda"
    }
]

我想為這個集合“Persons”中的每個文檔添加一個新字段，我可以在控制台上執行語法，但是由於我需要以某種方式存儲更改，所以我們使用的是 Mongock。 而且我找不到通過MongockTemplate執行update的方法。 文件的{ "key": "value" }是 static，我什至不需要變量來傳遞它們，最終文件應該如下所示：

[
    {
        "firstName" : "Foo",
        "phone" : "+1 111 1111",
        "car": "Toyota",
        "species" : "human"
    },
    {
        "firstName" : "Bar",
        "phone" : "+2 222 2222",
        "car": "Honda",
        "species" : "human"
    }
]

我不知道如何在MongockTemplate中執行如下查詢：

db.getCollection('Persons').update(
  {},
  { $set: {"species": "human"} },
  false,
  true
)

Here's the StackTrace:

Answer 1

任何你可以用普通的 MongoTemplate 做的事情，你也可以用 MongockTemplate 做。

在這種情況下，您可以調整 UpdateOptions 和其他一些東西，但它可以像

       Document updater = new Document()
          .append("$set", new Document().append("species", "human"));
        
       mongockTemplate.getCollection("Persons")
           .updateMany(new Document(), updater);

雖然之前的答案仍然有效，但在您發布錯誤日志后，我想我發現了問題。 您正在使用不兼容版本的 MongoDB Spring 數據和 Mongock 驅動程序。 一方面，您使用Z206E3718AF092F80CAE771CCACASZZZZ 3.0.5.RELEASE以及另一端， mongodb-spring-data-v3正在使用Mongock dripy88 todymymodb mongodb-spring-data-v2 Zpring-deby deby e eyy pe y is istaa-def2 toda toddatadatdatadatdatdatdatdat， mongodb-spring-data-v3代替。

因此，經過多次嘗試后，我找到了以下解決方案：通過 MongockTemplate 獲取 MongoTemplate Impl 的實例並使用它而不是 MongockTemplate。 我仍然不知道它為什么起作用。 如果我弄清楚了，我會更新這個線程。

@ChangeSet(order = "1", id = "updateData", author = "J. Souza")
  public void updateCollectionAddSpecieField(MongockTemplate mongockTemplate) {

    MongoTemplate template = mongockTemplate.getImpl();

    Query query = new Query();
    query.addCriteria(where(SPECIES_FIELD).exists(false));
    Update update = new Update();
    update.set(SPECIES, HUMAN);
    UpdateResult updateResult = template
        .updateMulti(query, update, "Collection-Name");

    log.info("Matched {} | Modified {}",
        updateResult.getMatchedCount(), updateResult.getModifiedCount());
  }
