• 在宿舍摸鱼，连续两天没来实验室。今天一来，打开电脑启动项目，控制台就出现了下列信息。项目启动异常，且控制台相对于啥都没说。

• 正常情况下，手动终止进程，退出代码为“-1”

  

• 试着重启项目、重启IDEA、重启电脑，都没有解决问题。果然重启不是万能的。

• 在网络上查询，并没有【进程已结束，退出代码为1】的文章，显然这不是一个常见错误。

  查询到其他类型的结束异常，IDEA 惊天 bug：进程已结束，退出代码 1073741819。里面介绍该异常是由于开启了其他软件，与IDEA之间存在莫名的联动，所以导致异常。关闭所有其他软件，我的异常仍未解决。

• 由于控制台未输出任何信息，所以根据道友的提示，我对启动项添加了try/catch环绕，在控制台输出异常信息。异常处理——SpringBoot项目启动后直接退出Process finished with exit code 1。

  【添加了try/catch环绕的方法：选中该部分代码，按下Ctrl+Alt+T，选择try/actch环绕】

  输出的错误信息如下：

  又是熟悉的错误，error creating bean with name ’ '。

  但这次不再是unsatisfied dependencies，因此仔细查看错误信息，发现都是关于springframework的问题，因此考虑替换springboot版本。

• 替换spring boot版本为2.3.10.RELEASE，更新maven信息后重启项目，启动成功！

• 不知道2.4.5 版本的spring boot抽啥风了。可能是项目中的一些配置在该版本下存在异常。在spring boot主页下生成一个基于2.4.5的quick start项目，在IDEA中仍能正常启动。
