SpringMVC日志追踪笔记整理

1. 新建logback-spring.xml

   <?xml version="1.0" encoding="UTF-8"?>
   <configuration><property name="PATH" value="./log/business"></property><appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"><encoder><Pattern>%d{mm:ss.SSS} %highlight(%-5level) %blue(%-30logger{30}:%-4line) %thread %green(%-18X{LOG_ID}) %msg%n</Pattern></encoder></appender><appender name="ERROR_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"><file>${PATH}/error.log</file><rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"><FileNamePattern>${PATH}/error.%d{yyyy-MM-dd}.%i.log</FileNamePattern><timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"><maxFileSize>10MB</maxFileSize></timeBasedFileNamingAndTriggeringPolicy></rollingPolicy><layout><pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level %-50logger{50}:%-4line %green(%-18X{LOG_ID}) %msg%n</pattern></layout><filter class="ch.qos.logback.classic.filter.LevelFilter"><level>ERROR</level><onMatch>ACCEPT</onMatch><onMismatch>DENY</onMismatch></filter></appender><root level="ERROR"><appender-ref ref="ERROR_FILE" /></root><root level="INFO"><appender-ref ref="STDOUT" /></root>
   </configuration>
   

2. 编写拦截器

   @Component
   public class LogInterceptor implements HandlerInterceptor {@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {// 增加日志流水号MDC.put("LOG_ID", System.currentTimeMillis() + RandomUtil.randomString(3));return true;}
   }
   

3. 配置拦截器

   @Configuration
   public class SpringMvcConfig implements WebMvcConfigurer {@ResourceLogInterceptor logInterceptor;@Overridepublic void addInterceptors(InterceptorRegistry registry) {registry.addInterceptor(logInterceptor).addPathPatterns("/**");}
   }
