带有依赖注入的Spring boot和Jersey过滤器

Question

问题是，Jersey服务器似乎不能使用Spring的ApplicationContext，我们在这里定义了这种依赖关系。

这里是JerseyConfiguration

@Configuration
public class JerseyConfig extends ResourceConfig {

    private static final String CONTEXT_CONFIG = "contextConfig";

    private static final String RESOURCE_PACKAGE = "presentation.resource";

    public JerseyConfig() {
        ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
        applicationContext.refresh();
        property(CONTEXT_CONFIG, applicationContext);
        register(SpringLifecycleListener.class);
        register(MyFilter.class); //Filter I want to use 
        packages(RESOURCE_PACKAGE);
    }
}

这里是具有@autowire的筛选器

@Priority(40)
@Primary
@Provider
@MyFilter
class MyFilter(@Context var resourceInfo: ResourceInfo) extends ContainerRequestFilter with DefaultRuntime {

  implicit var finagleService: CommonFinagleService = _

  @Primary
  @Autowired(required = false)
  def setHttpFinagleService(@Autowired(required = false)
                            @Primary
                            _finagleService: CommonFinagleService): Unit = {
    finagleService = _finagleService
    finagleService.init(getProperties())
  }

  override def filter(context: ContainerRequestContext): Unit = {
    logger.debug(null, "filter running.....")
  }
}

    }

您需要将Spring选择的myfilter作为Bean,

添加到类级别的@component并确保它是通过组件扫描拾取的，如果您有

请注意，如果使用Spring DI，@provider在这里可能是多余的
