package no.niths.rest;
// Imports ...
@Controller
@RequestMapping("courses")
public class CourseController implements SimpleREST<Course>{
@Autowired
public CourseService service;
}
そしてrespecticeサービス:
package no.niths.services;
// Imports ...
@Service
public class CourseService {
@Autowired
public ICourse repo;
}
そして最後に、私のapp-config.xml

は何これを引き起こしているとどのような問題が、このオートワイヤリング:ここは、更新されたスタックトレースのですか?
エラーが示すように、コードが正しくコンパイルされません。あなたが最初にそれをコンパイルすることができない場合、アプリケーションを展開するポイントはありません。 – skaffman
最初にコードをコンパイルしないのはなぜですか?私はそこでの思考過程を理解しているかどうかはわかりませ – AHungerArtist
@skaffman私は、Eclipseと何らかの継続的な統合機能を使用しているため、Mavenがビルドした後で、EclipseをSpringFabricサーバーにデプロイしようとしています。 – whirlwin
