java - 如何使用 Apache Camel REST DSL (Servlet/ReSTLet) 设置 HTTP 状态代码原因

Question

我有一个使用 Spring Boot 和 Apache Camel 构建的 Web 应用程序，并且正在实现 REST 接口(interface)。 目前，使用 Camel 默认 Servlet 或 ReSTLet 组件，我没有在响应中获取 HTTP 状态代码原因。

以下是将 HTTP 状态代码设置为 403 时收到的示例响应:

< HTTP/1.1 403 
< Date: Mon, 19 Feb 2018 10:01:21 GMT
< Server: Restlet-Framework/2.4.0
< Content-Type: application/json
< Content-Length: 75

应该如何:

< HTTP/1.1 403 Forbidden
< Date: Mon, 19 Feb 2018 10:01:21 GMT
< Server: Restlet-Framework/2.4.0
< Content-Type: application/json
< Content-Length: 75

如何配置 Camel/ReSTLet/Servlet 以在 HTTP 状态代码中包含原因？

我当前的配置:

应用程序.java

@SpringBootApplication
public class Application extends SpringBootServletInitializer {
    private static final Logger appLogger = LoggerFactory.getLogger(Application.class);
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
        appLogger.info("--Application Started--");
    }

    @Bean
    public ServletRegistrationBean servletRegistrationBean() {

        SpringServerServlet serverServlet = new SpringServerServlet();
        ServletRegistrationBean regBean = new ServletRegistrationBean(serverServlet, "/*");

        Map<String,String> params = new HashMap<>();
        params.put("org.restlet.component", "restletComponent");

        regBean.setInitParameters(params);

        return regBean;
    }


    @Bean
    public Component restletComponent() {
        return new Component();
    }

    @Bean
    public RestletComponent restletComponentService() {
        return new RestletComponent(restletComponent());
    }

}

路由配置:

@Component
public class RestRouteBuilder extends RouteBuilder {
    private static final Logger appLogger = LoggerFactory.getLogger(RestRouteBuilder.class);
    private Predicate isAuthorizedRequest = header(HttpHeaders.AUTHORIZATION).isNotNull();

    @Override
    public void configure() throws Exception {
        restConfiguration().component("restlet")
                           .contextPath("/overlay")
                           .bindingMode(RestBindingMode.json)
                           .skipBindingOnErrorCode(false)
                           .dataFormatProperty("prettyPrint", "true");

        rest("/")
                .get()
                .route()
                .setHeader(Exchange.HTTP_RESPONSE_CODE, constant(403))
                .setBody(constant("Forbidden"))
                .endRest();
    }
}

我还尝试添加 .setHeader(Exchange.HTTP_RESPONSE_TEXT,constant("Forbidden")) 但结果是相同的。

Answer 1

.setHeader(Exchange.HTTP_RESPONSE_CODE, constant(403))
.setHeader(Exchange.CONTENT_TYPE, constant("text/plain"))
.setBody(constant("Forbidden"))
