Log4j nosql appender无法对MongoDB服务器进行身份验证

Question

我正在尝试使用Apache Log4J NoSQL appender。我已将其配置为连接到我的MongoDB实例，但在使用Maven Install运行项目时，我似乎遇到了身份验证错误：

ERROR Failed to authenticate against MongoDB server. Unknown error.

我正在使用MongoDB 3.0.4并使用以下命令创建了以下用户：

use test
db.createUser({
    user:"logUser",
    pwd:"pwd",
    roles:["readWrite","dbAdmin"]
})

我已经检查过我可以使用以下方式连接：

mongo -u logUser -p pwd

我的log4j2.xml：

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="debug">
    <Appenders>
        <NoSql name="databaseAppender">
            <MongoDb databaseName="test" collectionName="logging" server = "localhost"
            port="27017" username = "logUser" password = "pwd"/>
        </NoSql>
    </Appenders>
    <Loggers>
        <Root level="debug">
            <AppenderRef ref="databaseAppender"/>
        </Root>
    </Loggers>
</Configuration>

以下是我的POM.xml配置更改：
