shell脚本保存为GBK编码文件执行curl请求时,发送的 Body为GBK编码，接收接口为SpringbootRest接口, 会出现乱码无法解析的问题。
解决方法：
方法1.Shell发送端：

转换为utf-8

    sourecontent="{"a":"我是中文"}"
    content=$(echo "$sourecontent" | iconv -c -f gbk -t utf-8)
     curl -X POST -D content http://xxxxxx

方法2：Springboot 服务端：
添加配置，对指定的url增加 Interceptors，添加编码处理

@Configuration
public class GbkConfiguration implements WebMvcConfigurer {
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new HandlerInterceptor() {
            @Override
            public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o) {
                try {
                    TriggerRunRequest request = null;
                    String bodyStr = IOUtils.toString(httpServletRequest.getInputStream(), "GBK");
//                    log.info("+++++++++++++++++++++++++111:{}", bodyStr);
                    if (StringUtils.hasText(bodyStr)) {
                        request = JsonUtils.parseObject(bodyStr, TriggerRunRequest.class).orElse(null);
                    }
                    httpServletRequest.setAttribute("request", request);
                    //httpServletRequest.


                } catch (IOException e) {
                    throw new RuntimeException(e);
                }
                return true;
            }

            @Override
            public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) {
            }

            @Override
            public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) {
            }


        }).addPathPatterns("/xxx/xxx").addPathPatterns("");

    }

//    @Override
//    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
//        FastJsonHttpMessageConverter fastJsonHttpMessageConverter = new FastJsonHttpMessageConverter();
//        FastJsonConfig fastJsonConfig = new FastJsonConfig();
//        fastJsonConfig.setCharset(Charset.forName("GBK"));
//        fastJsonHttpMessageConverter.setFastJsonConfig(fastJsonConfig);
//
//        List<MediaType> mediaTypes = Lists.newArrayList();
//        mediaTypes.add(MediaType.valueOf("application/json;charset=GBK"));
//        fastJsonHttpMessageConverter.setSupportedMediaTypes(mediaTypes);
//
//        HttpMessageConverter<?> converter = fastJsonHttpMessageConverter;
//        converters.add(0, converter);
//    }
