MongoTemplate.getCollectionNames和MongoTemplate,co

Question

我正在尝试获取数据库上的集合列表。我的应用程序使用spring-boot 2.4.1和Azure Cosmos DB。下面是代码块。

String uri= "mongodb://<username>:<password>@<hostname.documents.azure.com>:<port>/?ssl=true";
String dbName= "databaseName";
MongoClient mongoClient = MongoClients.create(uri);
SimpleMongoClientDatabaseFactory mongoDbFactory  = 
new SimpleMongoClientDatabaseFactory(mongoClient, dbName);
MongoTemplate mongoTemplate = new MongoTemplate(mongoDbFactory);
System.out.println(mongoTemplate.getCollectionNames());

代码抛出一个非常奇怪的StringIndexOutOfBoundsException。

异常堆栈:

Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: -4
at java.lang.String.substring(String.java:1931)

当我连接到一个mongo实例，运行在我的本地与连接字符串"mongodb://localhost:27017"上面的代码工作正常。

和我的pom.xml的相关部分

对这个错误有什么想法吗?

Answer 1

您确定您的连接uri正确吗?

i can see password part your uri

像这样添加密码部分uri

String uri= "mongodb://<username>:<password>@...
