私はアプリケーションを構築するためのSpring Bootを学んでいます。私は最初のSpring Bootアプリケーションを、アプリケーションとは別のパッケージのコントローラで構築しようとしています。 Tomcatのインスタンスが起動しますが、要求がURIに対して登録されたRestControllerに到達しません。続きSpringBootのRequestMappingが動作しない
は、コントローラクラスです:後
package com.spring.controllers;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class HelloController {
@RequestMapping(value = "/abc")
public String getHi() {
System.out.println("End Point hit");
return "Hi";
}
}
は、アプリケーションクラスである:
package com.spring.boot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication(scanBasePackages = {"com.spring.controllers"})
public class SpringBootMain {
public static void main(String args[]) {
SpringApplication.run(SpringBootMain.class, args);
}
}

私はベースパッケージのスキャンを追加しても、@ComponentScan
アノテーションでみましたが、私はURL(http://localhost:8080/abc)を打ったとき、結果は同じですしている。
予期しないエラー(タイプ=が見つかりませんでした、ステータスは=ありました404)。 メッセージがありません
誰も同じ問題に直面しましたか?これをどうやって解決したかをお教えください。
どのようにコントローラに到達していますか?どのURL? – pvpkiran
私が達するURLはhttp:// localhost:8080/abc – Devil
です。アプリケーションが起動すると、spring-bootはすべてのリクエストマッピングを表示します。マッピングが見えますか? – pvpkiran
