Log4j should be more familiar to you. Log4j2 is a relatively large upgrade of log4j. The bottom layer uses disruptor rewriting to optimize the asynchronous output log, which greatly improves the performance. The author has made performance comparison among log4j, logback and log4j2, and log4j2 does show absolute advantages. Not much to say, the ...

1. This paper mainly introduces how to use logback + slf4j to log in spring boot project. logback consists of three main components: Loggers, Appenders and Layouts. slf4j: Like jdbc, it defines a set of interfaces, which is a log facade, and enables fast switching between multiple log systems (by modifying configuration files) logback: and l ...

1. Background Recently, due to the needs of the project, we have migrated all versions of log4j 1.x to the version of log4j 2.x, and the subsequent slf4j integration log4j configuration (the perfect solution for building a project log system using Slf4j integration Log4j2) and log4j2 configuration file details require a good chat.This article i ...

Spring Basic Explanation Spring Basic Concepts This article only focuses on IoC and AOP. IoC (Control Inversion) Inversion of Control (IoC), also known as Dependency Injection, is a design concept in object-oriented programming to reduce the coupling between program codes.

Preface mybatis officially recommends using the mapper proxy method to develop the mapper interface. Programmers do not need to write mapper interface implementation classes. When using the mapper proxy method, the input parameters can use pojo wrapper object or map object to ensure the universality of dao. Traditional dao layer development ...

To add log4j to the existing engineering code and record the log information without destroying the original code structure, we need to download the package on the official website first. I downloaded apache-log4j-2.12.0-bin, download address: https://logging.apache.org/log4j/2.x/download.html 1. Fi ...
