MongoDB retryWrites = true不适用于3.6+版本

Question

我已通读https://docs.mongodb.com/manual/core/retryable-writes/并设置了所有必需的属性以使其正常运行，但到目前为止还算不上成功。

具有3个成员副本，并且程序正在运行以插入记录时，我杀死了主数据库，而在为新的主数据库进行选举时，我的代码中正在发生循环，并且当新成员被选举后，这些记录不会重试写入。

本地MongoDB版本

``
mongo --version
MongoDB shell version v3.6.6
git version: 6405d65b1d6432e138b44c13085d0c2fe235d6bd

Mongo Java驱动程序

``compile group: 'org.mongodb', name: 'mongodb-driver', version: '3.6.4'
compile group: 'org.mongodb', name: 'mongodb-driver-core', version: '3.6.4'
compile group: 'org.mongodb', name: 'bson', version: '3.6.4'``

Mongo连接字符串

``dbUri = "mongodb://localhost:28000,localhost:28001,localhost:28002/test?replicaSet=rs01&retryWrites=true&w=2";``

使用MongoClient创建连接

MongoClient mongoClient = new MongoClient(new MongoClientURI(dbUri));

insert正在使用insertOne如下

``


private static void insertData(MongoClient mongoClient) {
        MongoDatabase db = mongoClient.getDatabase("test");
        MongoCollection<Document> collection = db.getCollection("customer");
//      collection.withWriteConcern(WriteConcern.W2);

        deleteOldDocumets(collection);
        int customerId = 0;

        while (customerId < 1000) {

            ++customerId;
            try {
                Document document = new Document();
                document.put("name", "user" + customerId);
                document.put("age", customerId);
                collection.insertOne(document);

                logger.info("Customer : " + customerId + "  Time is : "
                        + LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS")));
                Thread.sleep(10);
            } catch (Exception e) {
                logger.info("Primary connection closed, starting election in 5 secs");
            }
        }
        mongoClient.close();
    }``

我在Java驱动程序3.6.3中遇到了同样的问题，而我的解决方案是将驱动程序版本升级到3.8.2。请同时检查此错误修复：   https://jira.mongodb.org/browse/JAVA-2859?jql=project%20%3D%20JAVA%20AND%20issuetype%20%3D%20Bug%20AND%20fixVersion%20%3D%203.7.1%20ORDER%20BY%20priority%20DESC
