Question

SpringApplication.run（DemoApp.class，args）发生了BeanCreationException，但它没有打印日志。为什么？（我可以让它运行，但为什么没有日志）

以下是我在调试时复制的异常

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.mybatis.spring.mapper.MapperScannerConfigurer#0' defined in class path resource [dao/spring-dao.xml]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [dao/spring-dao.xml]: Cannot create inner bean 'com.github.pagehelper.PageHelper#654c1a54' of type [com.github.pagehelper.PageHelper] while setting bean property 'plugins' with key [0]; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.github.pagehelper.PageHelper] for bean with name 'com.github.pagehelper.PageHelper#654c1a54' defined in class path resource [dao/spring-dao.xml]; nested exception is java.lang.ClassNotFoundException: com.github.pagehelper.PageHelper

这是源代码位置。

public ConfigurableApplicationContext run(String... args) {
    try{
       ......
    }catch (Throwable ex) {
        handleRunFailure(context, listeners, analyzers, ex);-------//stuck in here
        throw new IllegalStateException(ex);
    }
}


private void handleRunFailure(ConfigurableApplicationContext context,SpringApplicationRunListeners listeners, FailureAnalyzers analyzers,Throwable exception) {
    try {
        ......
    }catch (Exception ex) {
        logger.warn("Unable to close ApplicationContext", ex);
    }
    ReflectionUtils.rethrowRuntimeException(exception);-------//stuck in here
}


public static void rethrowRuntimeException(Throwable ex) {
    if (ex instanceof RuntimeException) {
        throw (RuntimeException) ex; --------//stuck in here and then all stopped
    }
    if (ex instanceof Error) {
        throw (Error) ex;
    }
    throw new UndeclaredThrowableException(ex);
}

我的项目使用rpc framework-dubbo进行了整合，并且发生了这种情况。我开始一个新项目，它工作正常。

springboot无法启动，但是没有打印异常日志？为什么呢？
