springmvc从stream中获取参数，加idea测试

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）
