配置log4j使用mongodb

Question

在一個Java項目中，我想將我的日誌條目存儲到像mongoDB這樣的noSQL數據庫中。下面是根據what apache claims to be working我log4j的配置：

<?xml version="1.0" encoding="UTF-8"?> 
<Configuration status="warn"> 
    <Appenders> 
    <NoSql name="databaseAppender"> 
     <MongoDb databaseName="testLogDB" collectionName="applicationLog" server="127.0.0.1" 
       username="user" password="123456" /> 
    </NoSql> 
    </Appenders> 
    <Loggers> 
    <Root level="warn"> 
     <AppenderRef ref="databaseAppender"/> 
    </Root> 
    </Loggers> 
</Configuration> 

和代碼片段來進行測試：

static final Logger logger = LogManager.getLogger(Log4j2Example.class.getName()); 
    public static void main(String[] args) { 
     logger.error("Log4j Example."); 
    } 

我得到這個錯誤：

我已經包含的log4j的NoSQL，蒙戈-java-driver，以及log4jcore和api到我的構建路徑。那麼，我在這裏錯過了什麼？隨意建議替代品。

我可以在你的log4j中找到的是端口號丟失。 樣品log4j的情況如下：

<Appenders> 
    <NoSql name="databaseAppender"> 
     <MongoDb databaseName="DB name" collectionName="collection name" 
      server="localhost:27017" username="user name" password="DB password" /> 
    </NoSql> 
</Appenders> 

<Loggers> 
    <Root level="trace"> 
     <AppenderRef ref="databaseAppender" /> 
    </Root> 

</Loggers> 

你可以在https://github.com/PiyushMittl/logging-wrapper-2x2

參考找到的NoSQL的appender我的示例代碼：https://logging.apache.org/log4j/2.0/manual/appenders.html#NoSQLAppender

注：以上示例使用log4j2。 x api。
