如何通过 Mongock 向集合中的所有文档添加新字段？
How to add new field to all documents in a collection trough Mongock?
我有一个文档集合，如下所示：
[
{
"firstName" : "Foo",
"phone" : "+1 111 1111",
"car": "Toyota"
},
{
"firstName" : "Bar",
"phone" : "+2 222 2222",
"car": "Honda"
}
]
而且我想为这个集合“Persons”中的每个文档添加一个新字段，我能够在控制台上执行语法，但由于我需要以某种方式存储更改，所以我们正在使用 Mongock。而且我找不到执行 update 槽 MongockTemplate 的方法。
文档的 { "key" : "value" } 是静态的，我什至不需要变量来传递它们，最终文档应该如下所示：
[
{
"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:
中执行下面的查询
db.getCollection('Persons').update(
{},
{ $set: {"species": "human"} },
false,
true
)
Here's the StackTrace:

Description:
An attempt was made to call a method that does not exist. The attempt was made from the following location:
com.github.cloudyrock.mongock.driver.mongodb.springdata.v2.decorator.impl.MongockTemplate.lambda$updateMulti(MongockTemplate.java:383)
The following method did not exist:
'com.mongodb.client.result.UpdateResult org.springframework.data.mongodb.core.MongoTemplate.updateMulti(org.springframework.data.mongodb.core.query.Query, org.springframework.data.mongodb.core.query.Update, java.lang.String)'
The method's class, org.springframework.data.mongodb.core.MongoTemplate, is available from the following locations:
jar:file:/home/johnnes/.m2/repository/org/springframework/data/spring-data-mongodb/3.0.5.RELEASE/spring-data-mongodb-3.0.5.RELEASE.jar!/org/springframework/data/mongodb/core/MongoTemplate.class
The class hierarchy was loaded from the following locations:

任何你可以用普通 MongoTemplate 做的事情，你也可以用 MongockTemplate 做。
在这种情况下，您可以调整 UpdateOptions 和其他一些东西，但它可以像
一样简单
Document updater = new Document()
.append("$set", new Document().append("species", "human"));
mongockTemplate.getCollection("Persons")
.updateMany(new Document(), updater);
所以，经过多次尝试，我找到了以下解决方案：
通过 MongockTemplate 获取 MongoTemplate Impl 实例，并使用它代替 MongockTemplate。我仍然不知道它为什么起作用。如果我弄明白了，我会更新这个帖子。
@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());
}
虽然之前的答案仍然有效，但在您发布错误日志后，我想我找到了问题所在。您正在使用 MongoDB Spring 数据和 Mongock 驱动程序的不兼容版本。一方面，您正在使用 MongoDB Spring 数据 3.0.5.RELEASE，另一方面，您正在使用 Mongock 驱动程序 mongodb-spring-data-v2，它旨在与 Spring 数据 2. 你应该使用 mongodb-spring-data-v3 而不是 .
更多信息，请查看official documentation。
我有一个文档集合，如下所示：
[
{
"firstName" : "Foo",
"phone" : "+1 111 1111",
"car": "Toyota"
},
{
"firstName" : "Bar",
