How to disable URL encoding in Spring RestTemplate?

问题

String url = serverUrl + metadata.getUri();
response = restTemplate.exchange(url, metadata.getAction(), requestEntity, metadata.getResponseType());

url contains the string

https://localhost/api/fm/info/dump/a\b\f\20170722_225714.jpg?lastModified=1507881481909

Spring RestTemplate encodes it to the following when requesting to server

https://localhost/api/fm/info/dump/a%5Cb%5Cf%5C20170722_225714.jpg?lastModified=1507881481909

FYI, I need to disable URL encoding so that the '\' characters are available on server side as it is a business requirement since our web server (Nginx) has been configured to perform some checks based on the path of the request containing '\' character.

Create a Configuration class and add the following code

@Configuration
public class RestTemplateConfig {

     
        @Bean
        public RestTemplate restTemplate() {
            DefaultUriBuilderFactory defaultUriBuilderFactory = new DefaultUriBuilderFactory();
            defaultUriBuilderFactory.setEncodingMode(DefaultUriBuilderFactory.EncodingMode.NONE);
            RestTemplate restTemplate = new RestTemplate();
            restTemplate.setUriTemplateHandler(defaultUriBuilderFactory);
            return restTemplate;
        }
}

Then Autowire your RestTemplate in any class Through Constructor injection.
