问题 I am working on a Coupon form in which I have some optional fields. Introduction: All the form field values are received as JSON and mapped into a Golang structure.

I did so to make it easier to scale both droplets in the future, and other applications may be connecting to the DB in the future, both on Ubuntu 18.04.

问题 I am trying to build mongo-cxx-driver in a CMake based project. This project is supposed to build on Windows, macOS and in an ubuntu container and I want to ensure that my software on all these platforms will use the same driver version so I cannot afford installing the driver and its dependencies via apt-get , brew etc. So I am left with one option: ExternalProject_Add . But I am having difficulty making that work given how libmongoc is setup. Below is the CMake module I currently have.

问题 Is there a way to find the query that was run against the database in spring data mongodb? I know this is possible in case of JPA. So was just wondering if there was something similar in Spring data MongoDB? 回答1: The easiest way is to set the log level to DEBUG for org.springframework.data.mongodb . 回答2: logging: level: org.springframework.data.mongodb.core.MongoTemplate: DEBUG To clarify Oliver's answer add that to the application.yml file or properties file. 来源： https://stackoverflow.com
