依赖

两种配置log4j的方式：

一定要新建一个log4j.properties文件

在yaml中直接配置  
在mybatis-config中配置

mapper-locations 貌似不管用依旧需要加注解[@Mapper][Mapper]

mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE configuration
            PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
            "http://mybatis.org/dtd/mybatis-3-config.dtd">
    <configuration>
    
        <settings>
            
            <setting name="logImpl" value="LOG4J"/>
    
            
            <setting name="cacheEnabled" value="true"/>
        </settings>
    
    </configuration>

log4j.properties文件

#将等级为DEBUG的日志信息输出到console和file这两个目的地，console和file的定义在下面的代码
    log4j.rootLogger=DEBUG,console,file
    
    #控制台输出的相关设置 fhadmin.cn
    log4j.appender.console = org.apache.log4j.ConsoleAppender
    log4j.appender.console.Target = System.out
    log4j.appender.console.Threshold=DEBUG
    log4j.appender.console.layout = org.apache.log4j.PatternLayout
    log4j.appender.console.layout.ConversionPattern=[%c]-%m%n
    
    
    #文件输出的相关设置 fhadmin.cn
    log4j.appender.file = org.apache.log4j.RollingFileAppender
    log4j.appender.file.File=./log/kai.log
    log4j.appender.file.MaxFileSize=10mb
    log4j.appender.file.Threshold=DEBUG
    log4j.appender.file.layout=org.apache.log4j.PatternLayout
    log4j.appender.file.layout.ConversionPattern=[%p][%d{yy-MM-dd}][%c]%m%n
    
    #日志输出级别 fhadmin.cn
    log4j.logger.org.mybatis=DEBUG
    log4j.logger.java.sql=DEBUG
    log4j.logger.java.sql.Statement=DEBUG
    log4j.logger.java.sql.ResultSet=DEBUG
    log4j.logger.java.sql.PreparedStatement=DEBUG

如果编译后找不到这两个文件

在pom.xml中加入：

<resources>
                
                <resource>
                    <directory>src/main/java</directory>
                    <includes>
                        <include>**/*.xml</include>
                    </includes>
                    <filtering>true</filtering>
                </resource>
    
                <resource>
                    <directory>src/main/resources</directory>
                    <includes>
                        <include>**/*.xml</include>
                        <include>**/*.properties</include>
                        <include>**/*.yaml</include>
                    </includes>
                    <filtering>true</filtering>
                </resource>
    
            </resources>
