springboot2 - 坑 - 解決put提交接收不到參數的問題

關鍵代碼（在springboot1.5中不加這一塊也是正常的，不知道為什么2.0就出現了這個問題）

    @Bean
    public HttpPutFormContentFilter httpPutFormContentFilter() {
        return new HttpPutFormContentFilter();
    }

@Configuration
@EnableWebMvc
public class MyWebMvcConfigurer implements WebMvcConfigurer {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        //設置允許跨域的路徑
        registry.addMapping("/**")
                //是否允許證書 不再默認開啟
                .allowCredentials(true)

                .allowedMethods("*")
                .allowedHeaders("*");
                //跨域允許時間
//                .maxAge(3600);

        //請求常用的三種配置，*代表允許所有，當時你也可以自定義屬性（比如header只能帶什么，只能是post方式等等）
