SpringMVC日志追踪笔记整理

1. 新建logback-spring.xml

   
   <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%nPattern>
           encoder>
       appender>
       <appender name="ERROR_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
           <file>${PATH}/error.logfile>
           <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
               <FileNamePattern>${PATH}/error.%d{yyyy-MM-dd}.%i.logFileNamePattern>
               <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                   <maxFileSize>10MBmaxFileSize>
               timeBasedFileNamingAndTriggeringPolicy>
           rollingPolicy>
           <layout>
               <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level %-50logger{50}:%-4line %green(%-18X{LOG_ID}) %msg%npattern>
           layout>
           <filter class="ch.qos.logback.classic.filter.LevelFilter">
               <level>ERRORlevel>
               <onMatch>ACCEPTonMatch>
               <onMismatch>DENYonMismatch>
           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 {
       @Override
       public 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 {
      @Resource
      LogInterceptor logInterceptor;
      @Override
      public void addInterceptors(InterceptorRegistry registry) {
          registry.addInterceptor(logInterceptor)
                  .addPathPatterns("/**");
      }
   }
