413 Request Entity Too Large - With Spring Boot and Rest Template
提问by aknon
Using Spring Rest Template to upload a 100 MB file, using a multipart post request.
使用 Spring Rest 模板上传 100 MB 文件，使用多部分发布请求。
Client Code:
客户代码：
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.MULTIPART_FORM_DATA);
MultiValueMap<String, Object> map = new LinkedMultiValueMap<String, Object>();
map.add("name", chunk.getFilename());
map.add("filename", chunk.getFilename());
map.add("flowChunkNumber", chunk.getNumber());
map.add("flowChunkSize", chunkSize);
map.add("flowIdentifier", chunk.getIdentifier());
map.add("flowTotalSize", chunk.getTotalSize());
map.add("flowCurrentChunkSize", chunk.getSize());
map.add("file", chunk.getResource() );
HttpEntity<MultiValueMap<String, Object>> entity = new HttpEntity<MultiValueMap<String, Object>>(map, headers);
ResponseEntity<String> response = executeForResponse(
baseUri().path("/api/v1/uploads/chunks")
.build().toUri(), HttpMethod.POST, entity, String.class);
However the server ( Springs Boot application deployed on Amazon AWS ) returns :
但是服务器（部署在 Amazon AWS 上的 Springs Boot 应用程序）返回：
org.springframework.web.client.HttpClientErrorException: 413 Request Entity Too Large
at org.springframework.web.client.DefaultResponseErrorHandler.handleError(DefaultResponseErrorHandler.java:91)
at org.springframework.web.client.RestTemplate.handleResponse(RestTemplate.java:614)
at org.springframework.web.client.RestTemplate.doExecute(RestTemplate.java:570)
at org.springframework.web.client.RestTemplate.execute(RestTemplate.java:545)
at org.springframework.web.client.RestTemplate.exchange(RestTemplate.java:466)
Strangely enough I can upload the same file using an angular JS code to the same Spring Boot application.
奇怪的是，我可以使用 angular JS 代码将同一个文件上传到同一个 Spring Boot 应用程序。
Though in angular code I use : forceChunkSize : true
虽然在角度代码中我使用： forceChunkSize : true
Can I do the same in java ?
我可以在 java 中做同样的事情吗？

Maybe this helps:
也许这有帮助：
SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory();
factory.setBufferRequestBody(false);
RestTemplate template = new RestTemplate(factory);
When sending large amounts of data via POST or PUT, it is recommended to change this property to false
通过POST或PUT发送大量数据时，建议将此属性改为false

Add This content your configuration class of application.
添加此内容您的应用程序配置类。
@Bean
public MultipartConfigElement multipartConfigElement() {
MultipartConfigFactory factory = new MultipartConfigFactory();
factory.setMaxFileSize("200MB");
factory.setMaxRequestSize("200MB");
return factory.createMultipartConfig();
}
