Spring MVC Log Configuration

First step: Pom.xml configuration, import the required jar package

<!--log4j log file Management Pack version--
<slf4j.version>1.6.6</slf4j.version>
<log4j.version>1.2.9</log4j.version>

<!--log File Management Pack--
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>${log4j.version}</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>${slf4j.version}</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>${slf4j.version}</version>
</dependency>

Step two: Web. XML configuration

<!--log Records-
<context-param>
<!--log configuration file path--
<param-name>log4jConfigLocation</param-name>
<param-value>classpath:log4j.properties</param-value>
</context-param>
<context-param>
<param-name>log4jExposeWebAppRoot</param-name>
<param-value>false</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

Step three: Log4j.properties (below are some configurations, please add and subtract as needed)

# # # set log levels # # #
Log4j.rootlogger = Debug, info, D, E

# # # Output to the console # # #
Log4j.appender.stdout = Org.apache.log4j.ConsoleAppender
Log4j.appender.stdout.Target = System.out
Log4j.appender.stdout.layout = Org.apache.log4j.PatternLayout
Log4j.appender.stdout.layout.ConversionPattern =%-d{yyyy-mm-dd HH:mm:ss} [%c]-[%p]%m%n
Log4j.logger.com.alibaba.alictf=info,debug,error

# # # Output to the log file # # #
LOG4J.APPENDER.D = Org.apache.log4j.DailyRollingFileAppender
Log4j.appender.d.file = D:/logs/infos/info.log
Log4j.appender.d.append = True
Log4j.appender.d.threshold = Debug,info
Log4j.appender.d.layout = Org.apache.log4j.PatternLayout
Log4j.appender.d.layout.conversionpattern =%-d{yyyy-mm-dd HH:mm:ss} [%t:%r]-[%p]%m%n

# # # Save exception information to separate file # # # #
LOG4J.APPENDER.E = Org.apache.log4j.DailyRollingFileAppender
Log4j.appender.e.file = D:/logs/errors/error.log
Log4j.appender.e.append = True
Log4j.appender.e.threshold = ERROR
Log4j.appender.e.layout = Org.apache.log4j.PatternLayout
Log4j.appender.e.layout.conversionpattern =%-d{yyyy-mm-dd HH:mm:ss} [%t:%r]-[%p]%m%n

Solution: Log4j-1.2.9.jar, Slf4j-api-1.6.6.jar, Slf4j-log4j12-1.6.6.jar (the version number to match the version number in the Pom.xml configuration file) is copied to the Tomcat root directory under the Lib folder, and the problem is resolved.
