Display mybatis query log in logback 1. Configuration file

There are many different implementations. Here is how to output the log to the console.

Mybatis: configuration: log-impl: org.apache.ibatis.logging.stdout.StdOutImpl II. Log of the customized package levellogging: level: # your repository package com.kingboy.repository: debug 3. Through the logback-spring.xml file

Add the following configuration to the file

/ / add this section and change it to your own package path to record the operation database sql in the log file

Springboot+mybatis

Mybatis: # Mark the xml file location of the mapper to be parsed mapper-locations: classpath:mapper/*.xml configuration: # org.apache.ibatis.logging.slf4j.Slf4jImpl log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

The specific implementation is to rewrite the StdOutImpl class

The implementation is as follows:

Package com.emily.infrastructure.datasource.log;import com.emily.infrastructure.logback.factory.LogbackFactory;import org.apache.ibatis.logging.Log / * * @ Description: record the mybatis sql statement in the log file to implement the class, which is a replacement for the org.apache.ibatis.logging.stdout.StdOutImpl class * @ Author: Emily* @ create: 2021/8/22*/public class LogBackImpl implements Log {public LogBackImpl (String clazz) {/ / Do Nothing} @ Override public boolean isDebugEnabled () {return true;} @ Override public boolean isTraceEnabled () {return true } @ Override public void error (String s, Throwable e) {LogbackFactory.module ("database", "database", s); e.printStackTrace (System.err);} @ Override public void error (String s) {LogbackFactory.module ("database", "database", s);} @ Override public void debug (String s) {LogbackFactory.module ("database", "database", s) } @ Override public void trace (String s) {LogbackFactory.module ("database", "database", s);} @ Override public void warn (String s) {LogbackFactory.module ("database", "database", s);}}

For the rewritten implementation class to take effect, replace the configuration with the implementation class, as follows:

Mybatis: # Mark the xml file location of mapper to be parsed mapper-locations: classpath:mapper/*.xml configuration: # org.apache.ibatis.logging.slf4j.Slf4jImpl log-impl: com.emily.infrastructure.datasource.log.LogBackImpl.
