【问题描述】:
我想运行以下命令来使用 MongoDB Java Driver 创建一个用户,
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);
但是发生了以下异常:
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)
看看roles字段是一个数组导致这个问题,能不能看看这个问题?谢谢
【问题讨论】:
-
看起来我发现了问题,createUserCommand.put("roles", new String[]{"userAdmin", "read", "readWrite", "dbAdmin", "dbOwner"}) ;数据库.runCommand(createUserCommand);应该是 List
角色 = new ArrayList (); roles.add("userAdmin); ... createUserCommand.put("roles", roles); database.runCommand(createUserCommand); 貌似支持List,不支持Array,真的很丑。 -
将其发布为答案。它也帮助了我。
