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
mybatis-config.xml
-
<?xml version="1.0" encoding="UTF-8" ?>
-
<!DOCTYPE configuration
-
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
-
"">
-
<configuration>
-
-
<settings>
-
<!--配置日志格式fhadmin.cn-->
-
<setting name="logImpl" value="LOG4J"/>
-
-
<!--开启二级缓存fhadmin.cn-->
-
<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>
-
<!-- 防止找不到mybatis的mapper.xml文件fhadmin.cn,在项目启动时候就导入进去-->
-
<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>
