我有一个非常简单的 spring 应用程序，但配置错误：
@SpringBootApplication()
public class SimpleApplication implements CommandLineRunner {
public static void main(String[] args) {
var ctx = SpringApplication.run(SimpleApplication.class, args);
System.exit(SpringApplication.exit(ctx));
}
public static class MyObject {}
//Oops - No bean provided!!!
@Autowired MyObject myObject;
@Override public void run(String... args) { }
}我收到以下错误（在 intellij 中）：
...
Consider defining a bean of type 'test.app.SimpleApplication$MyObject' in your configuration.
Process finished with exit code 1这正是我所期望的。
如果我spring-boot-devtools在maven中添加依赖：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<optional>true</optional>
</dependency>然后我得到以下信息：
...
Consider defining a bean of type 'test.app.SimpleApplication$MyObject' in your configuration.
Process finished with exit code 0看来添加这个包会导致spring boot返回错误的代码。
