SpringBoot2之PUT请求接收不了参数的解决方案

    @Bean
    public FilterRegistrationBean<HiddenHttpMethodFilter> testFilterRegistration3() {
        FilterRegistrationBean<HiddenHttpMethodFilter> registration = new FilterRegistrationBean<HiddenHttpMethodFilter>();
        registration.setFilter(new HiddenHttpMethodFilter());//添加过滤器
        registration.addUrlPatterns("/*");//设置过滤路径，/*所有路径
        registration.setName("HiddenHttpMethodFilter");//设置优先级
        registration.setOrder(2);//设置优先级
        return registration;
    }

<input type="hidden" name="_method" value="put" />

        String paramValue = request.getParameter(methodParam);  
        if("POST".equals(request.getMethod()) && StringUtils.hasLength(paramValue)) {  
            String method = paramValue.toUpperCase(Locale.ENGLISH);  
            HttpServletRequest wrapper = new HttpMethodRequestWrapper(request, method); 
            filterChain.doFilter(wrapper, response);  
        } else  
        {  
            filterChain.doFilter(request, response);  
        }  
}  

    @Bean
    public FilterRegistrationBean<HttpPutFormContentFilter> testFilterRegistration2() {
        FilterRegistrationBean<HttpPutFormContentFilter> registration = new FilterRegistrationBean<HttpPutFormContentFilter>();
        registration.setFilter(new HttpPutFormContentFilter());//添加过滤器
        registration.addUrlPatterns("/*");//设置过滤路径，/*所有路径
        registration.setName("HttpPutFormContentFilter");//设置优先级
        registration.setOrder(2);//设置优先级
        return registration;
    }

<form action="" method="put" enctype="application/x-www-form-urlencoded">  
    ......  
</form>
