查了很多资料，应该是jetty的一个bug，jetty版本jetty-9.4.6.v20170531。

原因还不是特别清楚，但是通过错误能够看出来与SLF4J有关，而且通过查资料能够看出和日志级别有关，原logback.xml 如下

<?xml version="1.0" encoding="UTF-8"?>
<configuration><appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"><layout class="ch.qos.logback.classic.PatternLayout"><Pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg\n</Pattern></layout><filter class="ch.qos.logback.classic.filter.ThresholdFilter"><level>INFO</level></filter></appender><root level="DEBUG"><appender-ref ref="STDOUT" /></root>
</configuration>

将<root level="DEBUG">改为<root level="INFO">可解决上面问题。具体原因有待验证。
