3.配置logback.xml日志配置文件

<?xml version="1.0" encoding="UTF-8"?><configuration scan="true" scanPeriod="1 seconds">    <contextListenter class="ch.gos.logback.classic.jul.levelChangePropagator">        <resetJUL>true</resetJUL>    </contextListenter>    <jmxConfigurator/>    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">        <encoder>            <pattern>logback: %d{HH:mm:ss.SSS} %logger{36} - %msg%n</pattern>        </encoder>    </appender>    <logger name="org.springframework.web" level="DEBUG"/>    <root level="info">        <appender-ref ref="console" />    </root></configuration>

该配置可以在控制台看到打印如下

logback: 15:11:24.302 o.s.w.s.h.BeanNameUrlHandlerMapping - Rejected bean name 'applicationEventMulticaster': no URL paths identifiedlogback: 15:11:24.320 o.s.w.s.m.m.a.RequestMappingHandlerAdapter - Looking for @ControllerAdvice: WebApplicationContext for namespace 'dispatcher-servlet': startup date [Thu Feb 23 15:11:23 CST 2017]; root of context hierarchylogback: 15:11:24.370 o.s.w.c.s.AnnotationConfigWebApplicationContext - Unable to locate LifecycleProcessor with name 'lifecycleProcessor': using default [org.springframework.context.support.DefaultLifecycleProcessor@94bf0b5]logback: 15:11:24.375 o.s.web.servlet.DispatcherServlet - Unable to locate MultipartResolver with name 'multipartResolver': no multipart request handling providedlogback: 15:11:24.377 o.s.web.servlet.DispatcherServlet - Unable to locate LocaleResolver with name 'localeResolver': using default [org.springframework.web.servlet.i18n.AcceptHeaderLocaleResolver@6f88c31e]logback: 15:11:24.380 o.s.web.servlet.DispatcherServlet - Unable to locate ThemeResolver with name '
