一、添加依赖（pom.xml）

<properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><project.build-version>1.0.0-BUILD-SNAPSHOT</project.build-version><java-version>1.6</java-version><org.springframework-version>4.1.6.RELEASE</org.springframework-version><org.slf4j-version>1.7.20</org.slf4j-version></properties><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-api</artifactId><version>${org.slf4j-version}</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>${org.slf4j-version}</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>jcl-over-slf4j</artifactId><version>${org.slf4j-version}</version></dependency>

二、在项目根目录下添加日志文件（log4j.xml）

1、文件概要例示

log4j.rootLogger=info,Console,Filelog4j.appender.Console=org.apache.log4j.ConsoleAppenderlog4j.appender.Console.Target=System.outlog4j.appender.Console.layout=org.apache.log4j.PatternLayoutlog4j.appender.Console.layout.ConversionPattern=[%c]%m%nlog4j.appender.File=org.apache.log4j.RollingFileAppender log4j.appender.File.File=F:/mybatis.loglog4j.appender.File.MaxFileSize=10MBlog4j.appender.File.Threshold=ALLlog4j.appender.File.layout=org.apache.log4j.PatternLayoutlog4j.appender.File.layout.ConversionPattern=[%p][%d{yyyy-MM-dd HH\:mm\:ss,SSS}][%c]%m%n

2、类似打印样例

[DEBUG][2016-04-04 10:28:02,183][org.springframework.core.env.StandardEnvironment]Adding [systemEnvironment] PropertySource with lowest search precedence
