[英]Spring cannot find app-config.xml from app-config-text.xml
[英]Cannot reach endpoints in Spring App. XML config
我试图了解 Spring 究竟是如何工作的,所以我制作了一个简单的单控制器应用程序。 可能我在xml配置中忘记了一些东西。
网页.xml:

<bean class="com.example.dogsrestapplication.controller.DogsController"/>
</beans>
狗控制器:
@RestController
@RequestMapping("/dogs")
public class DogsController {
@GetMapping
public Collection<Dog> getAll() {
return DOGS.values();
}
}
我在http://localhost:8080/dogs
得到 404 。
Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
我的配置有什么问题?
想法: run/debug configuration -> Deployement -> Application Context
。 Intellij Idea 在那里插入了一个完整的工件名称。 我在插入后找到了我的端点/
