如上图，每天会生成一个新的日志文件，然后日志进行分类，我这里只对error和info进行分类。
怎么做呢？
首先，在resource目录创建一个新文件，取名logback-spring.xml
<?xml version="1.0" encoding="UTF-8" ?>
<configuration >
<appender name="consoleLog" class="ch.qos.logback.core.ConsoleAppender">
<layout class="ch.qos.logback.classic.PatternLayout">
<pattern>
%d - %msg%n
</pattern>
</layout>
</appender>
<appender name="fileInfoLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>
ERROR
</level>
<onMatch>DENY</onMatch>
<onMismatch>ACCEPT</onMismatch>
</filter>
<encoder>
<pattern>
%msg%n
</pattern>
</encoder>
<!-- 滚动策略-->
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- 路径-->
<fileNamePattern>
/var/log/tomcat/sell/info.%d.log
</fileNamePattern>
</rollingPolicy>
</appender>
<appender name="fileErrorLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>
ERROR
</level>
</filter>
<encoder>
<pattern>
%msg%n
</pattern>
</encoder>
<!-- 滚动策略-->
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- 路径-->
<fileNamePattern>
/var/log/tomcat/sell/error.%d.log
</fileNamePattern>
</rollingPolicy>
</appender>
<root level="info">
<appender-ref ref="consoleLog" />
<appender-ref ref="fileInfoLog" />
<appender-ref ref="fileErrorLog" />
</root>
</configuration>
单例测试：
import lombok.Data;
import lombok.extern.slf4j.Slf4j;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest
@Slf4j
@Data
public class LoggerTest {
@Test
public void test1(){
String name="laomi";
String password="123456";
log.info("debug.....");
log.info("info.....");
log.error("error....");
log.info("name:{}, password:{}",name,password);
}
}
添加依赖：
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<scope>test</scope>
</dependency>
fileNamePattern这个是文件路径，我是在这个项目的同级目录找到新创建的文件夹的
以此文章以后方便二次使用。
