【踩坑】SpringBoot启动失败 报错invoke Exception invoking method manageApp

最后通过排查是logback文件配置错误

从SpringMVC项目移植出的logback.xml文件到SpringBoot2.1.3项目中并不兼容

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <!--子节点<contextName>：用来设置上下文名称，每个logger都关联到logger上下文，默认上下文名称为default。但可以使用<contextName>设置成其他名字，用于区分不同应用程序的记录。一旦设置，不能修改。-->
        <contextName>xxxxxxxx</contextName>
        <!-- encoders are by default assigned the type ch.qos.logback.classic.encoder.PatternLayoutEncoder -->
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>

SpringBoot2.1.3中的logback1.2.3不支持该属性

将<contextName>属性删除解决问题
