             Summary: MongoDb3 Appender not working when using a Connection Factory
                 Key: LOG4J2-2534
                 URL: https://issues.apache.org/jira/browse/LOG4J2-2534
             Project: Log4j 2
          Issue Type: Bug
          Components: Appenders, MongoDB
    Affects Versions: 2.11.1
            Reporter: Alex Donate


When using log4j-mongodb3 appender with a connection factory , receiving exception

2019-01-20 21:33:02,438 main ERROR Unable to write to database [noSqlManager\{ description=databaseAppender, bufferSize=0, provider=mongoDb{ database=logger } }] for appender [databaseAppender]. org.bson.codecs.configuration.CodecConfigurationException: *Can't find a codec for class org.apache.logging.log4j.Level.*

Here is my log4j2.xml for the nosql appender

 

<NoSql name="databaseAppender">
 <MongoDb3 databaseName="logger" collectionName="applicationLog" factoryClassName="logger.ConnectionFactory"
 factoryMethodName="getNewMongoClient" />
 </NoSql>



Here is my ConnectionFactory

 

public class ConnectionFactory {

public static MongoClient getNewMongoClient () {
 
 MongoClientURI uri = new MongoClientURI("mongodb://localhost:27017/logger"); 
 MongoClient client = new MongoClient(uri);
 
 return client;
 }
}

 

Work around solution was to add on the Connection Factory my own MongoClient Options, to add the Logger Codec

 

public static MongoClient getNewMongoClient () {
 
 MongoClientOptions.Builder optionsBuilder = MongoClientOptions.builder()
 .codecRegistry(CodecRegistries.fromRegistries(
 CodecRegistries.fromCodecs(new LevelCodec()),
 MongoClient.getDefaultCodecRegistry()));
 
 MongoClientURI uri = new MongoClientURI("mongodb://localhost:27017/logger",optionsBuilder);


 MongoClient client = new MongoClient(uri);
 
 return client;
 }

 

I feel this should be added as part of the MongoDbProvider .java, when using a Connection Factory to also set the Codec.
