Spring Boot file transformer implementation in java

I have created a standalone java application that transforms several file formats one to another.

So it works over the Main.java like

new DocxToHtmlConverter().docxToHtml("File.docx",".File.html");

I want to implement a spring boot application that does the same thing through localhost url.

I will also implement a selection algorithm on top of this. For example an if clauses to execute the wanted algorithm based on the input string extentions.(can be used endsWith(".docx") etc.

Basically, If i write like localhost:8080/{inputFile,outputFile} and then based on the file extension, related class will be chosen and i should be able to download the resulted file. In this case it is html.

I never used Spring before, so forgive me for my ignorence. I dont even know if this kind of operations are valid with Spring. Thats why I am asking.

What would be the best approach to go with? any kind of helpful links or ideas are highly appreciated.

There is many ways to do it. This response describes one solution that lets you keep your library spring agnostic.

You have to create a configuration class that will define a bean with your implementation. You will be able to directly inject this bean into any bean in your spring project

@Configuration
public class DocxToHtmlConverterConfig{
  @Bean
  public DocxToHtmlConverter docxToHtmlConverter(){
    return new DocxToHtmlConverter();
  }
}

This configuration class will create a bean with DocxToHtmlConverter implementation that you can autowayer in any component of your application as follows

@RestController //or @Controller or @{any annotation that declares a component}
public class MyService{
  @Autowired
  DocxToHtmlConverter docxToHtmlConverter;

  public void convertFile(){
    docxToHtmlConverter.docxToHtml("File.docx",".File.html");
  }   
}
