restTemplate设置访问超时详解编程语言

10         SimpleClientHttpRequestFactory requestFactory = new SimpleClientHttpRequestFactory();

12         requestFactory.setReadTimeout(1000);   
13    
14         //利用复杂构造器可以实现超时设置，内部实际实现为 HttpClient   
15         RestTemplate restTemplate = new RestTemplate(requestFactory);   
16    
17         //设置HTTP请求头信息，实现编码等

20         requestHeaders.set("Accept-Charset", "utf-8");   
21         requestHeaders.set("Content-type", "text/xml; charset=utf-8");// 设置编码   
22    
23         //利用容器实现数据封装，发送   
24         HttpEntity<String> entity = new HttpEntity<String>(mRequestXml, requestHeaders);   
25         returnXml = restTemplate.postForObject(mUrl, entity, String.class);   
26    
27         // 转码原因：RestTemplate默认是使用org.springframework.http.converter.StringHttpMessageConverter来解析   
28         // StringHttpMessageConverter 默认用的 ISO-8859-1来编码的
