在Spring Boot中增加HTTP Post maxPostSize [英] Increase HTTP Post maxPostSize in Spring Boot

问题描述

我有一个相当简单的Spring Boot Web应用程序，我只有一个HTML页面，其表单带有enctype="multipart/form-data".我收到此错误:

I've got a fairly simple Spring Boot web application, I have a single HTML page with a form with enctype="multipart/form-data". I'm getting this error:

多部分请求包含的参数数据(不包括上传的文件)超出了在关联的连接器上设置的maxPostSize的限制.

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

我正在使用Spring Boot的默认嵌入式tomcat服务器.显然，默认的maxPostSize值为2 MB.有什么办法可以编辑此值?最好通过application.properties这样做，而不是必须创建自定义bean或将xml文件弄乱.

I'm using Spring Boot's default embedded tomcat server. Apparently the default maxPostSize value is 2 megabytes. Is there any way to edit this value? Doing so via application.properties would be best, rather than having to create customized beans or mess with xml files.

推荐答案

找到了解决方案.将此代码添加到运行SpringApplication.run的同一类中.

Found a solution. Add this code to the same class running SpringApplication.run.

// 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
                }
            );
        }
    };
}

显然，将其添加到您的application.properties文件中也会增加maxPostSize，但我自己尚未尝试过，因此无法确认.

Apparently adding this to your application.properties file will also increase the maxPostSize, but I haven't tried it myself so I can't confirm.

multipart.maxFileSize=10Mb # Max file size.
multipart.maxRequestSize=10Mb # Max request size.
