Spring Boot：MongoDb：异常：NoSuchMethodError：com.mongodb.client.MongoCollection.insertOne(java.lang.Object)

Question

序幕：

我从 * 的答案中研究了这个主题。所有答案都指向依赖冲突，在我的情况下这似乎不是真的。 （如果我没有遗漏任何东西）

问题：

当我使用MongoTemplate 实现save 或insert 时，我在运行时 遇到此异常

mongoTemplate.save(saveObject, COLLECTION)
mongoTemplate.insert(insertObject, COLLECTION)

没有构建问题或编译问题。 对于我的用例，save 或 insert 方法在内部调用 MongoCollection<TDocument>.insertOne(TDocument doc)。如果我像下面这样实现它，它工作正常：

MongoCollection<Document> collection = mongoTemplate.getCollection(COLLECTION);
collection.insertOne(docToSave);

调试：

另外，如果我将调试点放在org.springframework.data.mongodb.core.MongoTemplate

collectionToUse.insertOne(dbDoc);//exception is thrown from here

并从调试器手动执行它，它可以工作！

因此不可能缺少实现，从gradle dependencies映射来看，似乎也没有冲突。

这是我的依赖结构：

Answer 1

删除spring-integration-mongodb 和mongo-java-driver 并仅使用spring-boot-starter-data-mongodb 解决了这个问题！我认为可以安全地假设 spring 正在寻找兼容的org.mongodb:mongo-driver-sync 实现。不过，我想听听其他人对此的看法。

仅供参考， spring-boot-starter-data-mongodb 降低了项目所需的所有实现，包括来自 org.mongodb:mongo-java-driver 的实现为 org.mongodb:mongo-driver-sync。

更改后的build.gradle：
