springmvc配置日志

1：maven项目添加的依赖

<dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>${slf4j.version}</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>log4j-over-slf4j</artifactId>
            <version>${slf4j.version}</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>jcl-over-slf4j</artifactId>
            <version>${slf4j.version}</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <version>${slf4j.version}</version>
        </dependency>
        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
            <version>1.2.17</version>
        </dependency>

2：配置日志文件log4j.propertites

log4j.rootLogger=debug, stdout, logfile
 
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
#log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n
log4j.appender.stdout.layout.ConversionPattern=- %m%n
 
log4j.appender.logfile=org.apache.log4j.RollingFileAppender
log4j.appender.logfile.File=d:\\reward\\reward.log
log4j.appender.logfile.MaxFileSize=10240KB
# Keep three backup files.
log4j.appender.logfile.MaxBackupIndex=3
# Pattern to output: date priority [category] - message
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%n
 
log4j.logger.com.opensymphony.xwork2=ERROR
 
# Control logging for other open source packages
log4j.logger.org.springframework=ERROR
log4j.logger.org.quartz=ERROR
log4j.logger.net.sf.ehcache=ERROR
log4j.logger.net.sf.navigator=ERROR
log4j.logger.org.apache.commons=ERROR
log4j.logger.org.apache.struts=ERROR
 
# Struts OgnlUtil issues unimportant warnings
log4j.logger.com.opensymphony.xwork2.util.OgnlUtil=error
log4j.logger.com.opensymphony.xwork2.ognl.OgnlValueStack=error
 
log4j.logger.org.apache=INFO
log4j.logger.java.sql.ResultSet=INFO
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG

3:整合在springmvc框架

在web.xml文件里加上

<!-- 日志记录 -->
    <context-param>
        <!-- 日志配置文件路径 -->
        <param-name>log4jConfigLocation</param-name>
        <param-value>classpath:log4j.properties</param-value>
    </context-param>
    <!-- 日志页面的刷新间隔 -->
    <context-param>
        <param-name>log4jRefreshInterval</param-name>
        <param-value>6000</param-value>
    </context-param>

<listener>
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
 </listener>

4:使用

final Logger logger = LoggerFactory.getLogger(UserInfoService.class);

logger.info(“成功了配置过程！！！");
