import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.slf4j.MDC;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;public class SessionInterceptor extends HandlerInterceptorAdapter {    /**     * 会话ID     */    private final static String SESSION_KEY = "sessionId";    @Override    public void afterCompletion(HttpServletRequest arg0,      HttpServletResponse arg1, Object arg2, Exception arg3)      throws Exception {  // 删除  MDC. remove(SESSION_KEY);    }    @Override    public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1,      Object arg2, ModelAndView arg3) throws Exception {    }    @Override    public boolean preHandle(HttpServletRequest request,      HttpServletResponse response, Object handler) throws Exception {  // 放SessionId  String token = TokenUtil. java.util.UUID.randomUUID().toString();  MDC. put(SESSION_KEY, token);  return true;    }}

2.然后在logback相应的配置中加上 seesionId的配置就可以了

<?xml version="1.0" encoding="UTF-8"?><configuration>   <property name="log.base" value="./log/logback" />   <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">     <encoder>       <pattern> %X{sessionId} %date [%thread] %-5level %logger{80} - %msg%n       </pattern>     </encoder>   </appender>   <appender name="logfile"     class="ch.qos.logback.core.rolling.RollingFileAppender">     <File> ${log.base}.log</File >     <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">       <FileNamePattern> ${log.base}.%d{yyyy -MM-dd}.log.zip </FileNamePattern>     </rollingPolicy>     <encoder>       <pattern> %X{sessionId} %date [%thread] %-5level %logger{80} - %msg%n       </pattern>     </encoder>   </appender>   <logger name="com.sample" level="TRACE" />   <root>     <level value="INFO" />     <appender-ref ref="stdout" />     <appender-ref ref="logfile" />   </root></configuration>

3.日志打出的时候就会有可以标识区分不同客户端的请求了,用前面不同的token区分
