spring boot上传CSV文件 MultiPartFile与CommonsMultiPartFile转换异常

报错信息

‘org.springframework.web.multipart.support.StandardMultipartHttpServletRequestStandardMultipartFile′torequiredtype′org.springframework.web.multipart.commons.CommonsMultipartFile′;nestedexceptionisjava.lang.IllegalStateException:Cannotconvertvalueoftype′org.springframework.web.multipart.support.StandardMultipartHttpServletRequestStandardMultipartFile′torequiredtype′org.springframework.web.multipart.commons.CommonsMultipartFile′;nestedexceptionisjava.lang.IllegalStateException:Cannotconvertvalueoftype′org.springframework.web.multipart.support.StandardMultipartHttpServletRequestStandardMultipartFile’ to required type ‘org.springframework.web.multipart.commons.CommonsMultipartFile’: no matching editors or conversion strategy found
 

解决方案：

方案1.直接将CommonsMutipartFile转为MutipartFile

方案2.如果继续使用CommonsMutipartFile，则在项目添加配置类

@Bean(name = "multipartResolver")
public CommonsMultipartResolver getCommonsMultipartResolver() {
    CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
    multipartResolver.setMaxUploadSize(20971520);
    multipartResolver.setMaxInMemorySize(1048576);
    return multipartResolver;
}

同时在spring boot的applications文件中加入

multipart.enabled=true
