org.bson.codecs.configuration.CodecConfigurationException：找不到类[Ljava.lang.String;

Question

我想运行以下命令来使用 MongoDB Java 驱动程序创建用户，

    client = new MongoClient(mongoClientURI);
    MongoDatabase database = client.getDatabase("db_1");

    Document createUserCommand = new Document();
    createUserCommand.put("createUser", "abc");
    createUserCommand.put("pwd", "abc");
    createUserCommand.put("roles", new String[]{"userAdmin", "read", "readWrite", "dbAdmin", "dbOwner"});         database.runCommand(createUserCommand);

但出现以下异常：

Exception in thread "main" org.bson.codecs.configuration.CodecConfigurationException: Can't find a codec for class [Ljava.lang.String;.
    at org.bson.codecs.configuration.CodecCache.getOrThrow(CodecCache.java:46)
    at org.bson.codecs.configuration.ProvidersCodecRegistry.get(ProvidersCodecRegistry.java:63)
    at org.bson.codecs.configuration.ChildCodecRegistry.get(ChildCodecRegistry.java:51)
    at org.bson.codecs.DocumentCodec.writeValue(DocumentCodec.java:174)
    at org.bson.codecs.DocumentCodec.writeMap(DocumentCodec.java:189)
    at org.bson.codecs.DocumentCodec.encode(DocumentCodec.java:131)
    at org.bson.codecs.DocumentCodec.encode(DocumentCodec.java:45)
    at org.bson.codecs.BsonDocumentWrapperCodec.encode(BsonDocumentWrapperCodec.java:63)

看起来角色字段是一个数组导致这个问题，有人可以看一下这个问题吗？谢谢

Answer 1

createUserCommand.put("roles", new String[]{"userAdmin", "read", "readWrite", "dbAdmin", "dbOwner"});
 database.runCommand(createUserCommand); 

应该是

List<String> roles = new ArrayList<String>(); 
roles.add("userAdmin); ... createUserCommand.put("roles", roles); database.runCommand(createUserCommand);

貌似支持List，不支持Array，真是丑陋

Answer 2

对于任何可能在 Kotlin 中遇到此问题的人：

val roles: List<String> = arrayListOf("role1", "role2")
