Spring 4和球衣的编程集成

Question

如何在球衣资源中自动装配我的spring bean？

我想凑齐一个使用spring初始化jax-rs资源中的字段的泽西应用程序。从谷歌搜索，似乎可能，但他们总是空。我的bean被创建，但没有被注入。

我的REST资源

@Path ("/clips") 
@Component 
public class ClipStreamService { 

    @Autowired 
    private ClipHandler clipHandler; 

    @GET 
    public Response defaultGet() { 
    Clip clip = clipHandler.getDefault(); <-- ***** throws an NPE ***** 

弹簧WebInitilizer

public class SpringWebInitialiser implements WebApplicationInitializer { 

    @Override 
    public void onStartup(ServletContext container) { 

    // Create the 'root' Spring application context 
    AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext(); 
    rootContext.register(RootConfig.class); 
    rootContext.setServletContext(container); 
    container.addListener(new ContextLoaderListener(rootContext)); 

    // Create the dispatcher servlet's Spring application context 
    AnnotationConfigWebApplicationContext dispatcherContext = new AnnotationConfigWebApplicationContext(); 
    dispatcherContext.register(WebConfig.class); 

    // Register and map the dispatcher servlet 
    ServletRegistration.Dynamic dispatcher = container.addServlet("dispatcher", new DispatcherServlet(dispatcherContext)); 
    dispatcher.setLoadOnStartup(1); 
    dispatcher.addMapping("/"); 
    } 
} 

和bean的配置（注意：我也尝试添加bean来RootConfig）

@Configuration 
@ComponentScan ({ ... }) 
public class WebConfig { 

    @Bean 
    public ClipHandler clipHandler() { 
    return new ClipHandler(); 
    } 
}

你可以在你的球衣资源中手动调用自动装配，如下所示：

@Context 
private ServletContext servletContext; 

@PostConstruct 
public void init() { 
    SpringBeanAutowiringSupport.processInjectionBasedOnServletContext(this, servletContext); 
}
