Having null response for a list of objects in REST API call with RestTemplate

由 柔情痞子 提交于 2020-01-06 07:17:30
问题 So I'm working on a REST client that consumes a REST API to get a JSON object using the Spring RestTemplate. So I get an HTTP 200 OK response but the list (equipment) inside the class object is null. But other fields are fetched. When I do the same request using the Postman it works well. What might be the reason for this? The RestTemplate code snippet : RestTemplate restTemplate = new RestTemplate(); HttpHeaders requestHeaders = new HttpHeaders(); requestHeaders.add("Content-Type",

小程序订阅消息推送（含源码）java实现小程序推送，springboot实现微信消息推送

由 雨燕双飞 提交于 2020-01-05 22:19:04
前面写过一篇云开发实现小程序订阅消息（模板消息）推送的文章， 《借助云开发实现小程序订阅消息和模板消息的推送功能》 是有好多同学用的是Java写后台，所以今天就再来写一篇Java后台实现小程序订阅消息推送的文章。 老规矩先看效果图 至于如何创建模板消息，如果获取模板id我这节就不再讲解，不知道的同学可以查看我上篇文章 《借助云开发实现小程序订阅消息和模板消息的推送功能》 里面有详细的讲解。 今天呢就来重点讲下如何在Java后台编写小程序订阅消息推送的知识。 其实我很早之前有写过一篇Java实现模板消息推送的，但是小程序后面用订阅消息替换了模板推送，所以我也会根据最新的知识点不定期的更新文章的。 发送订阅消息三步走 1，拿到用户的openid 2，获取access_token 3，调用小程序消息推送的接口 一，获取用户的openid 关于用户openid的获取，我写过很多篇文章了，也有录过视频出来的，还不知道怎么获取的同学，可以取翻看下我之前的文章，或者看下我录制的零基础入门小程序的视频： 《5小时零基础入门小程序云开发》 所以这一步不是今天的重点。 二，获取access_token 首先来看下access_token是什么，下图是官方给出的 其实通俗的讲，access_token就是小程序官方给我们提供的一个凭证，你要调用小程序官方的接口，就必须先拿到access_token

RestTemplate集成Ribbon超时重试机制

由 本小妞迷上赌 提交于 2020-01-04 01:55:24
简介 之前遇到配置ribbon的超时参数，发现无法让restTemplate生效，因此想要了解RestTemplate相关机制，以及与Ribbon集成时的相关逻辑； RestTemplate类图 RestTemplate继承祖父类HttpAccessor的createRequest方法和父类InterceptingHttpAccessor的getRequestFactory方法；这两个方法决定了每一个Request的创建机制； createRequest方法如下： protected ClientHttpRequest createRequest(URI url, HttpMethod method) throws IOException { ClientHttpRequest request = getRequestFactory().createRequest(url, method);//由子类定义的RequestFactory来进行创建Request if (logger.isDebugEnabled()) { logger.debug("Created " + method.name() + " request for \"" + url + "\""); } return request; } getRequestFactory方法如下： public

Spring RestTemplate (setBufferRequestBody as false) does not like MultiValueMap request body, which contains an InputStream object

由 假如想象 提交于 2020-01-01 12:18:07
问题 I am trying to forward a very large csv formatted file in a service to service manner. So, a user uploads a very large csv file (several GBs) that the backend receives as Spring's MultipartFile abstraction (my version is spring-web-4.3.3.RELEASE ). After that I forward the same MultipartFile through input stream to a different service using RestTemplate . All works fine, if setBufferRequestBody is true in request factory, but as expected, it blows up memory with out of memory error as file
