前面省略N，直接上传然后报错代码截图:

nested exception is org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.FileUploadBase$FileSizeLimitExceededException: The field upfile exceeds its maximum permitted size of 1048576 bytes.] with root cause
    org.apache.tomcat.util.http.fileupload.FileUploadBase$FileSizeLimitExceededException: The field upfile exceeds its maximum permitted size of 1048576 bytes.
    at org.apache.tomcat.util.http.fileupload.FileUploadBase$FileItemIteratorImpl$FileItemStreamImpl$1.raiseError(FileUploadBase.java:633)

我这里就截取 几个重要的报错信息了。

解决办法如下  在springboot中添加 配置信息

package mview.sys.main.config;
    
    import javax.servlet.MultipartConfigElement;
    import javax.servlet.Servlet;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
    import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
    import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
    import org.springframework.boot.autoconfigure.web.MultipartProperties;
    import org.springframework.boot.context.properties.EnableConfigurationProperties;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.web.multipart.MultipartResolver;
    import org.springframework.web.multipart.support.StandardServletMultipartResolver;
    import org.springframework.web.servlet.DispatcherServlet;
    
    @Configuration
    @ConditionalOnClass({ Servlet.class, StandardServletMultipartResolver.class, MultipartConfigElement.class })
    @ConditionalOnProperty(prefix = "spring.http.multipart", name = "enabled", matchIfMissing = true)
    @EnableConfigurationProperties(MultipartProperties.class)
    public class MultipartAutoConfiguration {
    	@Autowired
    	private MultipartProperties multipartProperties;
    
    	// public MultipartAutoConfiguration(MultipartProperties
    	// multipartProperties) {
    	// this.multipartProperties = multipartProperties;
    	// }
    
    	@Bean
    	@ConditionalOnMissingBean
    	public MultipartConfigElement multipartConfigElement() {
    		this.multipartProperties.setMaxFileSize("-1");
    		return this.multipartProperties.createMultipartConfig();
    	}
    
    	@Bean(name = DispatcherServlet.MULTIPART_RESOLVER_BEAN_NAME)
    	@ConditionalOnMissingBean(MultipartResolver.class)
    	public StandardServletMultipartResolver multipartResolver() {
    		StandardServletMultipartResolver multipartResolver = new StandardServletMultipartResolver();
    		multipartResolver.setResolveLazily(false);
    		return multipartResolver;
    	}
    }

application.properties

multipart.maxFileSize=10Mb
    multipart.maxRequestSize=10Mb
