Question

Whitelabel Error Page

    This application has no explicit mapping for /error, so you are seeing this as a fallback.

您可以通过使用

exclude = { ErrorMvcAutoConfiguration.class } 

在@SpringBootApplication注释中

即

 @SpringBootApplication(scanBasePackages = { "com.myapp.app" }, exclude = { ErrorMvcAutoConfiguration.class })

@EnableAutoConfiguration( exclude = { ErrorMvcAutoConfiguration.class })
