Spring boot 2.2.0-多部分文件上载失败，错误

Question

    public CertificateRequest uploadfileAndParse(@RequestParam("file") MultipartFile file, HttpServletRequest request){
        CertificateRequest certificateRequest = new CertificateRequest();
        if(!file.isEmpty()){
            certificateRequest.setCity("UN");
        }

        return certificateRequest;
    }

spring.servlet.multipart.enabled=true
spring.servlet.multipart.file-size-threshold=2KB
spring.servlet.multipart.max-file-size=200MB
spring.servlet.multipart.max-request-size=215MB

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.web.multipart.MultipartException: Failed to parse multipart servlet request; nested exception is java.lang.IllegalStateException: Unable to process parts as no multi-part configuration has been provided] with root cause
java.lang.IllegalStateException: Unable to process parts as no multi-part configuration has been providedat org.apache.catalina.connector.Request.parseParts(Request.java:2802) ~[tomcat-embed-core-9.0.27.jar:9.0.27]

不知道我还缺了什么。调试时我还发现

getAllowCasualMultiPartParsing（）显示为false。看起来tomcat上下文中没有设置多部分配置。我使用的是嵌入式tomcat。

您可以使用以下基于版本的配置

Spring Boot 1.3.x及更早版本

  multipart.maxFileSize
   multipart.maxRequestSize

Spring靴1.4.x和1.5.x

spring.http.multipart.maxFileSize
spring.http.multipart.maxRequestSize

spring.servlet.multipart.maxFileSize
spring.servlet.multipart.maxRequestSize

spring.servlet.multipart.maxFileSize
spring.servlet.multipart.maxRequestSize
