在我看来它正在重复查询。

我该怎么办？

【问题讨论】：

如果没有提供代码就很难追踪。大多数 IDE 都支持使用 xDebug 进行调试，您可以跟踪执行的每一行。 PHPStorm, Eclipse.. 选择你的武器并追踪它:)
您可以在级别 2（所有查询）启用 MongoDB profiler 以确认是否确实存在双重查询，或者这是否只是日志记录异常。我不熟悉 FOSUserBundle，但它可能会执行多个（重复）查询作为其逻辑的一部分。

【解决方案1】：

现在我认为它不会多次查询，它只是它的日志记录方式。在其他查询中，查询的每个部分都有 1 个日志行，但 dev 工具栏显示为 1 个查询，所以它必须是正确的。
