错误：
java.lang.IllegalArgumentException: state should be: databaseName does not contain ' '
意味着您尝试在MongoDB中创建带有空格的数据库名称。
MongoDB对数据库名称有一些规则。首先，数据库名称不区分大小写，因此名称不能仅因字符的大小写而异。数据库名称不能为空，并且必须少于 64 个字符。
如果您在Windows中运行MongoDB，则数据库名称不能包含以下任何字符，包括空格或空字符：
/. "$*<>:|?
如果您在Linux中运行MongoDB，则数据库名称不能包含以下任何字符，包括空格或空字符：
/. "$
