## 报错误信息 ##

The multi-part request contained parameter data (excluding uploaded files) that exceeded the limit for maxPostSize set on the associated connector.

可以看到在SB源码中post链接请求源码 默认参数

form表单pots提交size大小 超出默认限制

## 解决办法 ##

更改tomcat的post限制大小

硬编码方式

import org.springframework.boot.context.embedded.ConfigurableEmbeddedServletContainer;
    import org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer;
    import org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    /** * 设置post 参数大小 * * @author tizzy */
    @Configuration
    public class HttpMaxPostSizeConfiguration { 
    
    
        // Set maxPostSize of embedded tomcat server to 10 megabytes (default is 2 MB, not large enough to support file uploads > 1.5 MB)
        @Bean
        EmbeddedServletContainerCustomizer containerCustomizer() throws Exception { 
            return (ConfigurableEmbeddedServletContainer container) -> { 
                if (container instanceof TomcatEmbeddedServletContainerFactory) { 
                    TomcatEmbeddedServletContainerFactory tomcat = (TomcatEmbeddedServletContainerFactory) container;
                    tomcat.addConnectorCustomizers(
                            (connector) -> { 
                                connector.setMaxPostSize(10000000); // 10 MB
                            }
                    );
                }
            };
        }
    }

或者配置文件方式  
**tomcat**

`server.tomcat.max-http-post-size: 10MB`

**Jetty**

`server.jetty.max-http-post-size: 10MB`

**Undertow**

`server.undertow.max-http-post-size: 10MB`

## 最后配置文件里 请求大小 ##

spring:
      http:
        multipart:
          maxRequestSize: 100Mb
          maxFileSize: 10Mb

最后启动Sb.run
