Spring Cloud Gateway contains many built-in routing assertion factories. All these assertions can match different attributes of HTTP requests, and multiple routing assertion factories can be combined based on logic and status. 1. After routing […]

Foreword 1. Question Suppose you are developing a logistics management application. The initial version could only handle trucking, so most of […]
[mmdetection] featmap_strides and finest_scale in ROIExtractor
Featmap_strides is wrong and results in no performance When I used FasterRCNN to run my own data set, I found that there was almost no performance (0.8%). Later I found the reason and found that it was: In FasterRCNN, the featmap_strides of the SingleROIExtractor in the second stage is written as [8, 16, 32, 64] […]
Springboot extension point series_BeanFactoryPostProcessor
1. Functional features The execution of BeanFactoryPostProcessor is a very important part of the Spring Bean life cycle; BeanFactory level post-processor, org.springframework.beans.factory.config.BeanFactoryPostProcessor#postProcessBeanFactory will only be executed once during the Spring life cycle; Allows the BeanDefinition data to be read after the container reads the BeanDefinition data and before the bean is instantiated, and can be […]
