@requestbody接受参数有办法大小写不敏感和参数首尾有空格吗

如题，比如unitId变成各种不一致的大小写，或者和“unitId ”

这个要看前后端都是要遵循约定的格式,任何一方不按照约定的方式请求或者接收,都会不成功

不区分大小写可以加个配置类试试

@Configuration
public class FastjsonConfig {
    @Bean
    public HttpMessageConverters fastJsonHttpMessageConverters() {
　　　　　　//加上后，完全按照驼峰来，不许私自入参大小写不一
　　　　   JSON.DEFAULT_PARSER_FEATURE |= DisableFieldSmartMatch.getMask();

//1.需要定义一个convert转换消息的对象;
        FastJsonHttpMessageConverter fastJsonHttpMessageConverter = new FastJsonHttpMessageConverter();
        //2:添加fastJson的配置信息;
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
        //3处理中文乱码问题
        List<MediaType> fastMediaTypes = new ArrayList<>();
        fastMediaTypes.add(MediaType.APPLICATION_JSON);
        //4.在convert中添加配置信息.
        fastJsonHttpMessageConverter.setSupportedMediaTypes(fastMediaTypes);
        fastJsonHttpMessageConverter.setFastJsonConfig(fastJsonConfig);
        fastJsonConfig.setSerializerFeatures(
                SerializerFeature.DisableCircularReferenceDetect,
                SerializerFeature.WriteMapNullValue,
                SerializerFeature.WriteNullStringAsEmpty,
                SerializerFeature.WriteNullListAsEmpty,
                SerializerFeature.WriteDateUseDateFormat);
        fastJsonConfig.setDateFormat("yyyy-MM-dd HH:mm:ss");
        return new HttpMessageConverters(fastJsonHttpMessageConverter);
    }
}
