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

我想運行下面的命令來創建一個用戶用MongoDB的Java驅動程序，org.bson.codecs.configuration.CodecConfigurationException：找不到類[Ljava.lang.String;

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);

但以下異常：

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:45) 
    at org.bson.codecs.BsonDocumentWrapperCodec.encode(BsonDocumentWrapperCodec.java:63)

看起來角色字段，它是一個數組導致這個問題，有人可以看看這個問題嗎？由於

看起來像我想通了這個問題， createUserCommand.put（「角色」，new String [] {「userAdmin」，「read」，「readWrite」，「dbAdmin」，「dbOwner」}）; database.runCommand（createUserCommand）; 應該是列表 roles = new ArrayList （）; roles.add（「userAdmin）; ... createUserCommand.put（」角色」，角色）; database.runCommand（createUserCommand）; 看起來它支持列表，而不是數組，這實在是太醜了 – Tom

。發佈它作爲答案，它也幫助我。 – Jimmy

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

應該

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

看起來它支持列表，而不是數組，這實在是UGL
