springboot整合日志

1，排除spring-boot-starter自带的logback依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
            <exclusions>
                <!-- 排除自带的logback依赖 -->
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-logging</artifactId>
                </exclusion>
            </exclusions>
        </dependency>    

2、添加如下依赖：

        <!-- springboot-log4j -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-log4j</artifactId>
        </dependency>

3、创建log4j.properties,并添加相应配置信息

#log4j.rootLogger=CONSOLE,info,error,DEBUG
log4j.rootLogger=info,error,CONSOLE,DEBUG
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm}[%t][%c][%p]-%m%n
log4j.logger.info=info
log4j.appender.info=org.apache.log4j.DailyRollingFileAppender
log4j.appender.info.layout=org.apache.log4j.PatternLayout
log4j.appender.info.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm}[%t][%c][%p]-%m%n
log4j.appender.info.datePattern='.'yyyy-MM-dd
log4j.appender.info.Threshold = info
log4j.appender.info.append=true
#log4j.appender.info.File=/home/admin/pms-api-services/logs/info/api_services_info
log4j.appender.info.File=D://logs/info/api_services_info
log4j.logger.error=error
log4j.appender.error=org.apache.log4j.DailyRollingFileAppender
log4j.appender.error.layout=org.apache.log4j.PatternLayout
log4j.appender.error.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm}[%t][%c][%p]-%m%n
log4j.appender.error.datePattern='.'yyyy-MM-dd
log4j.appender.error.Threshold = error
log4j.appender.error.append=true
#log4j.appender.error.File=/home/admin/pms-api-services/logs/error/api_services_error
log4j.appender.error.File=D://logs/error/api_services_error
log4j.logger.DEBUG=DEBUG
log4j.appender.DEBUG=org.apache.log4j.DailyRollingFileAppender
log4j.appender.DEBUG.layout=org.apache.log4j.PatternLayout
log4j.appender.DEBUG.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm}[%t][%c][%p]-%m%n
log4j.appender.DEBUG.datePattern='.'yyyy-MM-dd
log4j.appender.DEBUG.Threshold = DEBUG
log4j.appender.DEBUG.append=true
#log4j.appender.DEBUG.File=/home/admin/pms-api-services/logs/debug/api_services_debug
log4j.appender.DEBUG.File=D://logs/debug/api_services_debug

4、在主要添加的类内部创建Logger对象，如：private static Logger log = Logger.getLogger(UserController.class);

而后就可以分级别添加日志信息了。

注意：如果不更改依赖，会出现日志文件无法导出的现象！
