  4. I have one project to parse some info from a large file. 
  5. The project uses maven and java:
  6. [![enter image description here][1]][1]
  7. And the structure bellow:
  8. [![enter image description here][2]][2]
  9. [1]: https://i.stack.imgur.com/zELbF.png
  10. [2]: https://i.stack.imgur.com/tJi5i.png
  11. When I run the application from my IDEA, I can read the file with:
  12. public  void buffer() throws IOException {
  13. try (InputStream inputStream = getClass().getResourceAsStream(&quot;/151279.txt&quot;);
  14. BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream))) {
  15. String contents = reader.lines()
  16. .collect(Collectors.joining(System.lineSeparator()));
  17. }
  18. }
  19. Then, if I run:
  20. ./mvnw package 
  21. java -jar target/file-parser-1.0-SNAPSHOT-runner.jar
  22. Everything goes well.
  23. Even when I generate the GraalNative jar and run the application from the native generate jar  with:
  24. ./mvnw package -Pnative -Dquarkus.native.container-build=true
  25. java -jar target/file-parser-1.0-SNAPSHOT-native-image-source-jar/file-parser-1.0-SNAPSHOT-runner.jar
  26. it all works Well.
  27. But then, when I run the commands to build and run with docker, is where I got my error:
  28. docker build -f src/main/docker/Dockerfile.native -t quarkus/file-parser 
  29. docker run -i --rm -p 8080:8080 quarkus/file-parser

  155. # 答案1
  156. **得分**: 11
  157. 你需要确保该资源已包含在本地镜像中（默认情况下不包含）。
  158. 添加一个 `src/main/resources/resources-config.json` 文件，内容类似于：

{
"resources": [
{
"pattern": "151279\.txt$"
}
]
}

  2. 你还需要设置以下属性：

quarkus.native.additional-build-args =-H:ResourceConfigurationFiles=resources-config.json

  2. 详见[此链接][1]以获取更多详情。
  3. [1]: https://quarkus.io/guides/writing-native-applications-tips#including-resources
  4. <details>
  5. <summary>英文:</summary>
  6. You need to make sure that the resource is included in the native image (it isn&#39;t by default).
  7. Add a `src/main/resources/resources-config.json` that includes something like:
  8. {
  9. &quot;resources&quot;: [
  10. {
  11. &quot;pattern&quot;: &quot;151279\\.txt$&quot;
  12. }
  13. ]
  14. }
  15. You will also need to set the following property:
  16. quarkus.native.additional-build-args =-H:ResourceConfigurationFiles=resources-config.json
  17. See [this][1] for more details.
