java的原生rabbitmq客户端允许在连接设置上设置心跳,例如:

import com.rabbitmq.client.ConnectionFactory;

...

ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setAutomaticRecoveryEnabled(true);
        connectionFactory.setHost("some://host");
        connectionFactory.setConnectionTimeout(5000);
        connectionFactory.setRequestedHeartbeat(5); // keeps an idle connection alive

Rabbitmq客户端使用心跳设置做什么？它是否向特殊交换/队列发送存根消息或者其他什么？

有人可以详细解释一下吗？

我想要构建的是一个spring-boot(v1.2.3)应用程序,并使用SpringFox(swagger2)v2.0.0公开我的Rest API

我的Swagger Spring配置

@EnableSwagger2
@Configuration
public class SwaggerConfig {

    @Bean
    public Docket myApi() {
        return new Docket(DocumentationType.SWAGGER_2)
            .genericModelSubstitutes(DeferredResult.class)
            .useDefaultResponseMessages(false)
            .forCodeGeneration(false)
            .pathMapping("/my-prj");
    }

}

我需要使用gson将我的pojo转换为json,我这样做:

@Configuration
public class GsonHttpMessageConverterConfig {

    @Bean
    public GsonHttpMessageConverter gsonHttpMessageConverter(Gson gson) {
        GsonHttpMessageConverter converter = new GsonHttpMessageConverter();
        converter.setGson(gson);
        return converter;
    }
}

麻烦的是,如果使用GsonHttpMessageConverter,swagger v2会生成错误的json:

{
"value": "{\"swagger\":\"2.0\",\"info\":{\"description\":\"Api Documentation\",\"version\":\"1.0\",\"title\":\"Api Documentation\",\"termsOfService\":\"urn:tos\",\"contact\":{\"name\":\"Contact Email\"},\"license\":{\"name\":\"Apache 2.0\",\"url\":\"http:
...

JSON以value为前缀,真正的JSON成为转义字符串.

这是如果不使用它应该如何GsonHttpMessageConverter:

{
"swagger": "2.0",
"info": {
"description": "Lorem Ipsum is simply dummy text of the printing and typesetting industry. …
