Start the print log settings

There are two ways: first planted into the configuration file, the second increase mybatis configuration file code

The first method: the implant profile, properties

 

　　File name: log4j.properties

　　content:

　　　　# Global logging configuration\uff0c\u5efa\u8bae\u5f00\u53d1\u73af\u5883\u4e2d\u8981\u7528debug
　　　　log4j.rootLogger=DEBUG, stdout
　　　　# Console output...
　　　　log4j.appender.stdout=org.apache.log4j.ConsoleAppender
　　　　log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
　　　　log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

Placement:

Into the controller layer -resources, just check out the content can only see, can not see, sql statement is executed

-Resources into the service layer or layers -resources in dao, only to see the sql statement, see the contents to be queried

 

The print more content, more cumbersome relative to the second method, the second method is recommended

 

The second method: Increase xml file code

Code content:

<Settings> 
<-! start print log -> 
<Setting name = "logImpl" value = "STDOUT_LOGGING" /> 
</ Settings> 

placement: 
xml configuration file dao layer
