我试图将文件上传到我的控制器。

这是我的控制器的上部。它一直有效，直到我达到 +- 2MB 的最大请求大小

> @RequestMapping(value = {"/runlocalfiles"}, method =
> RequestMethod.POST, produces = "application/json")
>     @ResponseBody
>     @CrossOrigin(origins = "http://localhost:4200")
>     public ResponseEntity run( HttpServletRequest request) {
>         String jsonBase64Files = request.getParameter("base64files");
>         String jsonChecks = request.getParameter("checks");

浏览器中的错误消息：

> Failed to load http://localhost:5001/runlocalfiles: No
> 'Access-Control-Allow-Origin' header is present on the requested
> resource. Origin 'http://localhost:4200' is therefore not allowed
> access. The response had HTTP status code 500.

Java 控制台中的错误：

> java.lang.IllegalStateException: The multi-part request contained
> parameter data (excluding uploaded files) that exceeded the limit for
> maxPostSize set on the associated connector   at
> org.apache.catalina.connector.Request.parseParts(Request.java:2893)
> ~[tomcat-embed-core-8.5.20.jar:8.5.20]...

我试图通过向 application.properties 添加新行来增加上传大小。还尝试将 -1 更改为例如 100MB

> spring.servlet.multipart.max-file-size= -1
> spring.servlet.multipart.max-request-size= -1
> spring.http.multipart.max-file-size = -1
> spring.http.multipart.max-request-size= -1

任何帮助都是有价值的。

所以我找到了一个可行的解决方案。我需要结合你的两个解决方案。

将此添加到初始类：

// 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(100000000); // 100 MB
                    }
            );
        }
    };
}

这对应用程序属性：

spring.http.multipart.max-file-size=100MB
spring.http.multipart.max-request-size=100MB

试试这个，它对我有用，将它添加到应用程序属性中：

server.tomcat.max-http-post-size=-1

如果你使用 Spring Boot 并嵌入 tomcat，你可以试试这个：

@SpringBootApplication  
public class SpringBootWebApplication {  

    //private int maxUploadFileSize = 10 * 1024 * 1024;  

    public static void main(String[] args) throws Exception {  
        SpringApplication.run(SpringBootWebApplication.class, args);  
    }  


    //Tomcat large file upload connection reset  
    @Bean  
    public TomcatEmbeddedServletContainerFactory tomcatEmbedded() {  

        TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory();  

        tomcat.addConnectorCustomizers((TomcatConnectorCustomizer) connector -> {  
            if ((connector.getProtocolHandler() instanceof AbstractHttp11Protocol<?>)) {  
                //-1 means unlimited  
                ((AbstractHttp11Protocol<?>) connector.getProtocolHandler()).setMaxSwallowSize(-1);  
            }  
        });  

        return tomcat;  
    }  
}

我按照以下Spring Boot 文件上传教程进行操作，如教程中所述，以下属性对我来说非常有效：

spring.servlet.multipart.max-file-size=300MB
spring.servlet.multipart.max-request-size=300MB
spring.http.multipart.enabled=false
