spring-loaded の jar をダウンロードして、アプリケーションのルート カタログに入れました。したがって、-javaagent:springloaded-1.3.0.BUILD-20210404.024037-2.jar -noverify のパラメーターを持つスプリング ブート アプリケーションを実行します。クラス ファイルを再構築するために ctrl+f9 のコマンドを入力すると、次のようなメッセージが表示されます。 :
Reloading: JVMPlugin: warning: unable to clear BEANINFO_CACHE, cant find field
私の単純な *.java は次のとおりです。
@RestController
@RequestMapping("/")
public class Chief {
private String user = "222222";
@RequestMapping("/welcome")
public String wwwwww() {
return user;
}
}
その後、再度 URL にアクセスすると、次のようなエラーが表示されます。
