Java Spring引导rest控制器未映射

我正在构建简单的testrestapi，基本上当调用/testing时，它将创建一个日志对象并将其发送到另一个api（独立于项目及其运行）。但无论何时去/测试，都不能通过控制器。奇怪的是，它以前是工作的。我在application.properties中包含了logging.level.org.springframework.web=DEBUG。下面是日志和我的源文件

您的

RestController

未被调用，因为您将

@ComponentScan

注释与固定的

basePackages

一起添加到

TestProjectApplication.java

中，它不包括控制器中的包。这意味着Spring将永远不会扫描您的

控制器

包，并且它无法注册任何端点

---

要解决这个问题，只需从您的

TestProjectApplication.java

中删除

@ComponentScan

，默认行为是扫描所有包，这样您的控制器就可以再次访问了。

非常感谢，我真的被这个问题困住了。我无法删除组件扫描，因为我需要它来扫描导入的外部库。所以我添加了这个

@ComponentScan（basePackages={“my.com.cybersolution.skb.eloginglibrary.filter.elogingfilter”，“my.com.cybersolution.skb.testproject”}）

package my.com.cybersolution.skb.testproject.client;

import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;

import my.com.cybersolution.skb.testproject.object.LoggingObject;

@FeignClient(name = "eloggingClient", url = "localhost:9090")
@Component
public interface TestClient {
    @PostMapping("/logging")
    public boolean sendMessage(@RequestBody LoggingObject logging);
}
