转载：logback不同业务的日志打印到不同文件
一、logback.xml文件配置如下：
<?xml version="1.0" encoding="UTF-8" ?>
<configuration>
<contextName>nana</contextName>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<Pattern>[%d{HH:mm:ss.SSS}] [%5level] [%thread] %logger{36} %msg%n</Pattern>
<charset>UTF-8</charset>
</encoder>
</appender> <appender name="INFO_NANA" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>../normalInfo.log</file> <encoder>
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} -%msg%n</pattern>
<charset>UTF-8</charset>
</encoder>
<!--过滤器,只打INFO级别的日志-->
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>INFO</level>
<onMatch>ACCEPT</onMatch>
<onMismatch>DENY</onMismatch>
</filter> <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
<fileNamePattern>normalInfo.%i.log</fileNamePattern>
<minIndex>1</minIndex>
<maxIndex>3</maxIndex>
</rollingPolicy> <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<maxFileSize>10MB</maxFileSize>
</triggeringPolicy>
</appender> <appender name="ERROR_NANA" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>../normalError.log</file> <encoder>
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} -%msg%n</pattern>
<charset>UTF-8</charset>
</encoder>
<!--过滤器,只打ERROR级别的日志-->
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>ERROR</level>
<onMatch>ACCEPT</onMatch>
<onMismatch>DENY</onMismatch>
</filter> <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
<fileNamePattern>normalError.%i.log</fileNamePattern>
<minIndex>1</minIndex>
<maxIndex>3</maxIndex>
</rollingPolicy> <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<maxFileSize>10MB</maxFileSize>
</triggeringPolicy>
</appender> <!--不同业务逻辑的日志打印到不同文件-->
<appender name="FIRST_NANA" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>../firstInfo.log</file> <encoder>
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} -%msg%n</pattern>
<charset>UTF-8</charset>
</encoder>
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>INFO</level>
<onMatch>ACCEPT</onMatch>
<onMismatch>DENY</onMismatch>
</filter> <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
<fileNamePattern>firstInfo.%i.log</fileNamePattern>
<minIndex>1</minIndex>
<maxIndex>3</maxIndex>
</rollingPolicy> <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<maxFileSize>10MB</maxFileSize>
</triggeringPolicy>
</appender> <appender name="SECOND_NANA" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>../secondInfo.log</file> <encoder>
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} -%msg%n</pattern>
<charset>UTF-8</charset>
</encoder>
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>INFO</level>
<onMatch>ACCEPT</onMatch>
<onMismatch>DENY</onMismatch>
</filter> <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
<fileNamePattern>secondInfo.%i.log</fileNamePattern>
<minIndex>1</minIndex>
<maxIndex>3</maxIndex>
</rollingPolicy> <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<maxFileSize>10MB</maxFileSize>
</triggeringPolicy>
</appender>
<!-- 不同的业务逻辑日志打印到指定文件夹-->
<logger name="first" level="info" additivity="false">
<appender-ref ref="FIRST_NANA"/>
</logger>
<logger name="second" level="info" additivity="false">
<appender-ref ref="SECOND_NANA"/>
</logger> <!--info和error分开打印-->
<root level="INFO">
<appender-ref ref="STDOUT"/>
<appender-ref ref="INFO_NANA"/>
<appender-ref ref="ERROR_NANA"/>
</root> </configuration>
二、工具类配置：
创建与logback.xml的logger名相对应的对象：
public enum LogFileName {
// 与logback.xml的logger name 相同
FIRST("first"),
SECOND("second");
private String logFileName;
LogFileName(String fileName) {
this.logFileName = fileName;
}
public String getLogFileName() {
return logFileName;
}
public void setLogFileName(String logFileName) {
this.logFileName = logFileName;
}
public static LogFileName getAwardTypeEnum(String value) {
LogFileName[] arr = values();
for(LogFileName item : arr) {
if(null != item && StringUtils.isNotBlank(item.logFileName)) {
return item;
}
}
return null;
}
}
指定logger日志存储路径，工具类：
public class LoggerUtil {
public static <T> Logger logger(Class<T> clazz) {
return LoggerFactory.getLogger(clazz);
}
/**
* 打印到指定的文件下
* @param desc 日志文件名称
* @return
*/
public static Logger logger(LogFileName desc) {
return LoggerFactory.getLogger(desc.getLogFileName());
}
}
测试如下：
@RestController
public class UserController { Logger FIRST_LOG = LoggerUtil.logger(LogFileName.FIRST);
Logger SECOND_LOG = LoggerUtil.logger(LogFileName.SECOND); @RequestMapping("/bb")
public String bb() {
FIRST_LOG.info("firsthaha");
SECOND_LOG.info("secondhaha");
return "bb";
} }
结果如下图：
