Spring boot RestTemplate - multipart/mixed

由 三世轮回 提交于 2019-12-11 06:41:46
问题 Have a REST API which only accepts content type multipart/mixed. Trying to use restTemplate and generate REST request with content type multipart/mixed. If I comment setContentType restTemplate defaults to multipart/form-data. setContentType(MediaType.parseMediaType("multipart/mixed")) But no luck, any example how I can call API generating multipart/mixed request? Maybe this helps HttpHeaders publishHeaders = new HttpHeaders(); publishHeaders.set(HEADER_TABLEAU_AUTH, token); publishHeaders

Streaming upload via @Bean-provided RestTemplateBuilder buffers full file

由 人走茶凉 提交于 2019-12-11 04:09:52
问题 I'm building a reverse-proxy for uploading large files (multiple gigabytes), and therefore want to use a streaming model that does not buffer entire files. Large buffers would introduce latency and, more importantly, they could result in out-of-memory errors. My client class contains @Autowired private RestTemplate restTemplate; @Bean public RestTemplate restTemplate(RestTemplateBuilder restTemplateBuilder) { int REST_TEMPLATE_MODE = 1; // 1=streams, 2=streams, 3=buffers return REST_TEMPLATE

How to access Spring REST API in JHipster with Spring RestTemplate

由 十年热恋 提交于 2019-12-11 04:06:22
问题 I have set up JHipster like described on its homepage with some entities. Frontend with AngularJS works great and also the API page, lets me test my services as expected. Now I am trying to write a REST-Client using Spring's RestTemplate like this: public List<SomeEntity> getAllEntities(){ URI uri = URI.create("http://localhost:8080/api/entities"); HttpHeaders httpHeaders = this.createHeaders("admin", "admin") ResponseEntity<SomeEntity[]> responseEntity = restTemplate.exchange(uri, HttpMethod

Spring REST consuming JSON uppercase vs lowercase

由 ε祈祈猫儿з 提交于 2019-12-11 02:59:42
问题 I am trying to create simple webservice, that is reading JSON from URL and gives it back. I followed spring.io tutorial about this. I am probably missing something about naming conventions? JSON I use doesn't have nice naming convention. Some values are in uppercase, some lowercase other are mixed. What I understood for proper matching with restTemplate I need to follow these names. My object structure: public class Page { private String name; //works private String about; // works private

SpringCloud springcloud是一个分布式的整体解决方案、springcloud为开发者提供了在分布式系统（配置管理、服务发现、熔断、路由、微代理、控制总线、一次性token、全局锁、leader选举、分布式session、集群状态）中快速构建的工具。 SpringCloud分布式开发五大常用组件 服务发现–Netflix Eureka 客服端负载均衡–Netflix Ribbon 断路器–Netflix Hystrix 服务网关–Netflix Zuul 分布式配置–Spring Cloud Config 搭建Eureka服务发现中心 1、书写一个yml文件来标明此为注册中心 server : port : 8761 eureka : instance : hostname : euraka - server #euraka实例主机名 client : register-with-eureka : false #不把自己注册到euraka上 fetch-registry : false #不从eureka上来获取服务的注册信息 service-url : defaultZone : http : //localhost : 8761/eureka/ 2、@EnableEurekaServer 可以将项目作为SpringCloud中的注册中心。 3

Spring Cloud Ribbon

由 孤人 提交于 2019-12-10 23:39:11
Spring Cloud Ribbon:负载均衡的服务调用 前言 什么是Ribbon？ Spring Cloud Ribbon是一套实现客户端负载均衡的工具，注意是 客户端 ，当然也有服务端的负载均衡工具，如Ngnix，可以认为Ribbon就是一个负载均衡(Load Balancer)。负载均衡就是将用户的请求平摊的分配到多个服务器，从而达到系统的高可用。 简单来说，Ribbon的主要功能是 提供客户端的软件负载均衡算法，将Netflix的中间层服务连接在一起 。 在微服务架构中，很多服务都会部署多个，其他服务去调用该服务的时候，如何保证负载均衡是个不得不去考虑的问题。负载均衡可以增加系统的可用性和扩展性，当我们使用RestTemplate来调用其他服务时，Ribbon可以很方便的实现负载均衡功能。 RestTemplate的使用 RestTemplate是一个HTTP客户端，使用它我们可以方便的调用HTTP接口，支持GET、POST、PUT、DELETE等方法。 GET请求方法 <T> T getForObject(String url, Class<T> responseType, Object... uriVariables); <T> T getForObject(String url, Class<T> responseType, Map<String, ?>
