背景：直接接收流数据，直接输出流数据
@RestController @Slf4j public class HelloController { @PostMapping(value = "/hello",produces = "application/json") public void hello(HttpServletRequest request, HttpServletResponse response) throws IOException { String encoding = request.getCharacterEncoding();
// 从流中获取数据 String body = StreamUtils.copyToString(request.getInputStream(), Charset.forName(encoding)); log.info("log : {} ",body); String resp="<html><head>i am head</head><body>i am body <body></html>";
// 将数据写入输出流中 response.getOutputStream().write(resp.getBytes()); }
idea插件测试接口，类似postman功能
位置：tools--> http client --> test restful web service
（愿idea越发强大）
