我尝试在Boot中使用CommonsMultipartResolver将我的旧应用程序（WAR）转换为Boot，现在它得到了以下代码：

@Configuration
    public class TestConfig {

        @Bean
        public FilterRegistrationBean openEntityManagerFilterRegistrationBean() {
            // Set upload filter
            final MultipartFilter multipartFilter = new MultipartFilter();
            final FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(multipartFilter);
            filterRegistrationBean.addInitParameter("multipartResolverBeanName", "commonsMultipartResolver");

            return filterRegistrationBean;
        }

        @Bean
        public CommonsMultipartResolver commonsMultipartResolver() {
            final CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver();
            commonsMultipartResolver.setMaxUploadSize(-1);

            return commonsMultipartResolver;
        }
    }

这是Boot中正确的方法，导致我看到了一些属性要应用到application.properties中。它们与定义FilterRegistrationBean的目的是否相同？

# MULTIPART (MultipartProperties)
multipart.enabled=true
multipart.file-size-threshold=0 # Threshold after which files will be written to disk.
multipart.location= # Intermediate location of uploaded files.
multipart.max-file-size=1Mb # Max file size.
multipart.max-request-size=10Mb # Max request size.

谁能提供样品使用方法？谢谢。

顺便说一句，它试图设置属性“ multipart.enabled = true”，我得到了：

Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'enabled' of bean class [org.springframework.boot.autoconfigure.web.MultipartProperties]: Bean property 'enabled' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
