Spring RestTemplate POST method for Xml Response?

折月煮酒 提交于 2019-12-06 01:09:45
I've tested a POST request via REST API tool and getting the response in an XML format. I'm not sure which method need to use and what should the response type class for the above. Could someone help me with the code snippet for the same? Thanks, Kathir Satish Pandey You need to add xml message converter to covert the xml messages to java objects. See solution Stack Overflow Also you can capture the result in String format and manually handle it then. Example : String xmlData = restTemplate.postForObject(url, parameters, String.class); // pass this string to xml parser and prepare java object

问题 I am trying to consume a restful ws with basic auth. I did not import any cert into my keystore. When I use chrome plugin Advance Rest client to test it (using basic auth with base64 encoded username:pass). I can see the response back. So far so good. But when I develop Java code to consume this ws, I get SSL handsake failure: org.springframework.web.client.ResourceAccessException: I/O error: Received fatal alert: handshake_failure; nested exception is javax.net.ssl.SSLHandshakeException:

I use spring android in a thread dedicated to execute spring android requests. I can't achieve to abort a request launched from spring android (a getForObject for instance). I tried to : reach the underlying input stream to close but it is completely wrapped in springandroid restemplate and can't be accessed from outside interrupt the thread get the request factory of the rest template and call destroy get the connection manager of the factory and call shutdown change the rest template factory's http client change the rest template factory's request factory but I can't abort a request and send

自定义HttpMessageConverter实现RestTemplate的exchange方法返回自定义格式数据

北慕城南 提交于 2019-12-05 20:07:06
一 概述 实现如下效果代码,且可正常获取到返回数据: ResponseEntity<JsonObject> resEntity = restTemplate.exchange(url, HttpMethod.GET, requestEntity, JsonObject.class,uriVariables); restTemplate的get和POST请求都有类型参数设置,所以可以直接返回转换成自定义的格式.比如: restTemplate.getForObject("http://www.baiud.com",JsonObject.class); 但是exchange是无法指定返回类型的,只能使用spring默认提供的几种转换器转换的格式,定义其他格式会报错或者返回实体body为空 restTemplate的post方法支持设置header,但是get方法不支持,假如现在有个需求,使用get方法需要设置header权限,且返回我想要的格式,那么自定义HttpMessageConverter就派上用场了 也提现了spring非常强大的可扩展性 二 步骤 新建自定义转换类: /** * 接口请求返回数据格式转换处理类,只处理String->JsonObject */ public class StringToJsonObjectMessageConverter extends

问题 I have a method on the Server side which gives me information about an specific name registered in my database. I'm accessing it from my Android application. The request to Server is done normally. What I'm trying to do is to pass parameter to the server depending on the name I want to get. Here's my Server side method: @RequestMapping("/android/played") public ModelAndView getName(String name) { System.out.println("Requested name: " + name); ........ } Here's the Android request to it:

Hystrix断路器 熔断器Hystrix的在Ribbon的集成

Hystrix作用 资源隔离 (限流) :包括 线程池隔离 和 信号量隔离 ,限制调用分布式服务的资源使用, 某一个调用的服务出现问题不会影响其他服务调用。 熔 断 : 当失败率达到阀值自动触发降级 ( 如因网络故障 / 超时造成的失败率高 ) ,熔断器触发的快速失败会进行快速恢复 。 降级机制 : 超时降级、资源不足时 ( 线程或信号量 ) 降级,降级后可以配合降级接口返回托底数据。 缓存:提供了请求缓存、请求合并实现。 A. 1.导包 <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-hystrix</artifactId> </dependency> 2.在主配置类上加注解 @EnableCircuitBreaker package cn.jiedada; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.cloud.client.circuitbreaker

自己动手写一个服务网关-java

自己动手写一个服务网关 原文链接:https://www.cnblogs.com/bigben0123/p/9252444.html 引言 什么是网关?为什么需要使用网关? 如图所示,在不使用网关的情况下,我们的服务是直接暴露给服务调用方。当调用方增多,势必需要添加定制化访问权限、校验等逻辑。当添加API网关后,再第三方调用端和服务提供方之间就创建了一面墙,这面墙直接与调用方通信进行权限控制。 本文所实现的网关源码抄袭了---Oh,不对,是借鉴。借鉴了Zuul网关的源码,提炼出其核心思路,实现了一套简单的网关源码,博主将其改名为Eatuul。 题外话 本文是业内能搜到的第一篇自己动手实现网关的文章。博主写的手把手系列的文章,目的是在以最简单的方式,揭露出中间件的核心原理,让读者能够迅速了解实现的核心。需要说明的是,这不是源码分析系列的文章,因此写出来的代码,省去了一些复杂的内容,毕竟大家能理解到该中间件的核心原理即可。如果想看源码分析系列的,请关注博主,后期会将spring、spring boot、dubbo、mybatis等开源框架一一揭示。 正文 设计思路 先大致说一下,就是定义一个Servlet接收请求。然后经过preFilter(封装请求参数),routeFilter(转发请求),postFilter(输出内容)。三个过滤器之间,共享request
