Mybatis learning 3______ use log4j print log information

(In this case project done in maven test :)

1. leader packet: in pom.xml

        <!-- log4j -->
        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
            <version>1.2.17</version>
        </dependency>

2. log4j.properties file is carried out under the src / resources to write:

### Log4j configuration ### 
### and Spring combined with the need to specify the file location in web.xml, and add listeners ### 
output level and the output destination #define log4j (destination can customize the name, and the following correspondence) 
# [Level], appenderName1, appenderName2 
Log4j.rootLogger = the DEBUG, Console, File

log4j.appender.console = org.apache.log4j.ConsoleAppender tells that 
log4j.appender.console.Target = the System.out 
log4j.appender.console.Threshold the DEBUG = 
#### log flexibility to specify the output format, the following line is designated specific format ### 
# C%: category output log information belongs, is usually the full name of the class where 
#% m: output code specified message, the generated specific information log 
#% n: output a carriage return linefeed, Windows platform "/ r / n", Unix platform "/ n" output log information wrap 
log4j.appender.console.layout = org .apache.log4j.PatternLayout 
log4j.appender.console.layout.ConversionPattern = [% C] -% m% n-

# define the maximum file size 
log4j.appender.file.MaxFileSize = 10MB 
### output log ###

log4j.appender.file.Threshold = ERROR 
log4j.appender.file.layout = Org.apache.log4j.PatternLayout 
log4j.appender.file.layout.ConversionPattern = [P%] [% {D the MM-dd}-YY] [% C]% m% n-

Configure 3.mybatis core file:

  < Settings > 
        < Setting name = "logImpl" value = "LOG4J" /> 
    </ Settings > 
 
(prepared note configuration parameter sequence)
