apache-camel - 如何在 apache camel 中发送空响应以进行休息呼叫

问题描述

我有删除操作的休息服务，实际上什么都不返回。如何在 Apache 骆驼休息服务中返回 nothing()void 响应作为响应

@RequestMapping(value = URI_REMOVE_ACTIVITY_DELETE, method = DELETE)
    public void delete(@PathVariable Long id) {
        super.delete(id, principal);
    } 
    Class<Void> RESULT_URI_REMOVE_ACTIVITY_DELETE = void.class;

标签： apache-camelspring-camel

解决方案

这是一个可以进一步改进的原始实现。

public class MyRouteBuilder extends RouteBuilder {

    public void configure() {

        restConfiguration().component("jetty").host("localhost").port("8080");

        rest().produces("application/json").delete("/something/{id}").to("direct:delete");
        from("direct:delete")
                .log("Delete ${in.header.id}")
                .process(exchange -> {
                    String id = exchange.getIn().getHeader("id",String.class);
                    //doDelete(id);
                })
                .setHeader(Exchange.HTTP_RESPONSE_CODE,constant(200));


    }
}

exchange.getIn().getHeader("id",String.class)是 的粗略等价物@PathVariable。@RequestMapping(value = URI_REMOVE_ACTIVITY_DELETE, method = DELETE)应该成为.delete(URI_REMOVE_ACTIVITY_DELETE)

来自下面服务器的响应 在此处输入图像描述

修改后的代码bindingMode设置为 JSON。

 public void configure() {

    restConfiguration().component("jetty").host("localhost").port("8080").bindingMode(RestBindingMode.json);

    rest().produces("text/plain").delete("/something").to("direct:delete");
    from("direct:delete")
            .process(exchange -> {
                Map<String, Object> requestObject = (Map<String, Object>) exchange.getIn().getBody();
                //doDelete(requestObject.get("id"));
            })
            .setHeader(Exchange.HTTP_RESPONSE_CODE, constant(200));


}
