org.apache.catalina.core.StandardService - Stopping service [Tomcat]

今天在启动springboot项目突然启动失败，但是在测试日志文件，以为是日志出错，下面这个是logback打印的异常信息。

 

2019-05-30 15:09:10.686 [restartedMain] INFO com.alibaba.druid.pool.DruidDataSource - {dataSource-2} inited
2019-05-30 15:09:10.831 [restartedMain] INFO com.alibaba.druid.pool.DruidDataSource - {dataSource-2} closed
2019-05-30 15:09:10.833 [restartedMain] INFO org.apache.catalina.core.StandardService - Stopping service [Tomcat]

但其实错误在使用逆向工程时，重复运行导致mapper.xml文件错误。但是logback打印不出这个错误。闪电logback配置文件之后（当然有备份），springboot的默认日志（部分）：

看我标红的地方，这就指向很清晰了，后来发现是因为我在logback配置文件中加了：

<!-- 控制台输出 -->
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符-->
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
<charset>utf-8</charset>
</encoder>
<!-- 日志级别的配置 -->
<filter class="ch.qos.logback.classic.filter.LevelFilter"><!-- 只打印DEBUG日志 -->
<level>INFO</level>
<onMatch>ACCEPT</onMatch>
<onMismatch>DENY</onMismatch>
</filter>
</appender>

 

日志的配置过滤掉了这个error级别的日志，所以无法显示。

 

因为之前也查了百度上关于这个异常的信息，出错的地方各不相同，所以还是要仔细查看日志。
