Log4j->SLF4j->Logback是同一個人開發(fā)的

import lombok.extern.slf4j.Slf4j;
import org.junit.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
public class LoggerTest {// private  final Logger log= LoggerFactory.getLogger(LoggerTest.class);@Testpublic void test1(){log.debug("debug test...");log.info("info test...");log.error("error test...");String name="kelly";String password="123456";log.error("error test...name:{},password:{}",name,password); //占位符使用}}

lombok的使用

IntelliJ IDEA lombok插件的安裝和使用：
https://jingyan.baidu.com/article/0a52e3f4e53ca1bf63ed725c.html
用注解@Slf4j代替private final Logger log= LoggerFactory.getLogger(LoggerTest.class);
使用時直接用log去記錄日志

        <dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency>

Logback的配置

1.application.yml配置

logging:file: D:/logs/test/log.txt

2.logback-spring.xml配置(建議用這種)

<?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><!--該過濾器過濾掉ERROR--><onMatch>DENY</onMatch><onMismatch>ACCEPT</onMismatch></filter><encoder><pattern>%msg%n</pattern></encoder><!--滾動策略--><rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"><!--路徑--><fileNamePattern>d:/logs/test/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><!--滾動策略--><rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"><!--路徑--><fileNamePattern>d:/logs/test/error.%d.log</fileNamePattern></rollingPolicy></appender><root level="debug"><appender-ref ref="consoleLog" /><appender-ref ref="fileInfoLog" /><appender-ref ref="fileErrorLog" /></root>
</configuration>
