次の構造を持つ Maven Multi Module プロジェクトがあります。

  • Site-Parent
    -- Site-UI
    -- Site-Entity
    -- Site-Services
    -- Sites-Repository


個人用サイト UI web.xml:

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>com.mysite.app.web.spring</param-value>
`</context-param>


com.mysite.app.web.spring 内の AppConfig.java:

@Configuration
@ImportResource({ "classpath*:contextConfig.xml",
        "classpath*:securityConfig.xml" })
@ComponentScan(basePackages = "com.mysite.app.web.controller")
public class AppConfig
{
    @Bean
    public AnnotationMethodHandlerAdapter annotationMethodHandlerAdapter()
    {
        ...
    }

    @Bean
    public SpringTemplateEngine templateEngine()
    {
        ...
    }

    ...
}


com.mysite.app.web.spring 内の WebConfig.java:

@EnableWebMvc
@ComponentScan({ "com.mysite.app.web.controller" })
@Configuration
public class WebConfig extends WebMvcConfigurerAdapter
{

    public WebConfig()
    {
        super();
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry)
    {
        registry.addResourceHandler("/css/**").addResourceLocations("/css/");
        registry.addResourceHandler("/js/**").addResourceLocations("/js/");
        registry.addResourceHandler("/img/**").addResourceLocations("/img/");
    }

    @Override
    public void addInterceptors(InterceptorRegistry reg)
    {
        reg.addInterceptor(new BaseInterceptor());
        reg.addInterceptor(new SecurityInterceptor());
        //reg.addInterceptor(new AddCardInterceptor());
    }
}


これが私のコントローラーの1つです：

@Controller
public class PurchaseController extends AppController
{
    static Logger logger = LoggerFactory.getLogger(PurchaseController.class);

    @Autowired
    private IPurchaseService purchaseService;

        ...
}


アプリの起動時に次のエラーが表示されます。

サービスがスキャンされていないことが原因であることはわかっています。

サービスモジュールには次のものがあります。

@Configuration
@ComponentScan(basePackages = "com.mysite.services")
public class ServicesConfig
{
}

私が知る必要があるのは、それらをスキャンするようにアプリを構成する方法です。できるだけ多くの構成をコードで維持し、xml ファイルの使用を避けたいと考えています。

ありがとう

解決策を考え出しました。

各モジュールのスプリング構成ファイルのパッケージの場所を指定する必要があります。これは、Site-UI モジュールの web.xml で行います。

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>com.mysite.app.web.spring com.mysite.services.spring com.mysite.persistence.spring</param-value>
</context-param>

これを行うためのより良い方法があるかもしれません。私は提案を受け付けています。
