03-Implementing AOP based on annotations
Using Spring’s AOP AspectJ is a framework organized by Eclipse that supports AOP. It is a framework independent of the Spring framework. Spring’s implementation of AOP includes several methods The first way (commonly used): AOP implemented by the Spring framework combined with the AspectJ framework based annotation method The second method (commonly used): Spring framework […]

IOC and AOP of Spring system
Foreword Spring is a lightweight Inversion of Control (IoC) and Aspect-Oriented (AOP) container framework. IOC 1. Concept of IOC Inversion of Control (IoC=Inversion of Control) IoC, in vernacular terms, means that the container controls the (dependency) relationship between programs, instead of being directly controlled by program code in traditional implementations. This is the so-called “inversion […]
AOP and MDC implement log tracking
Foreword In actual development, log output is very important. In a production environment, if the logs are well typed, problems can be quickly checked. In order to better view the logs, we need to connect these logs in series, which will make the troubleshooting problems easier. Got to be more relaxed. It just so happens […]
