situations, you can delegate to the static SpringApplication.run     
method, as shown in the following example:

SpringApplication类提供了一个非常便捷的方式通过main（）方法去启动Spring应用。在大多数情况下，您可以通过委托给静态方法SpringApplication.run（）去启动，如下：

By default, INFO logging messages are shown, including some     
relevant startup details, such as the user that launched the     
application. If you need a log level other than INFO, you can     
set it, as described in Section 26.4, “Log Levels”,

默认情况下，INFO级别的日志将会展示出来，包括一些相应的启动细节，诸如启动程序的用户等。如果您需要展示不仅仅是INFO级别的日志，您可以设置它，详情参照26.4章节“Log Levels”。
