java - How to return actual html file using JAX-RS

Question

asked Oct 24, 2021 in Technique[技术] by 深蓝 (71.8m points)

so far, I'm returning html my home page by:

@GET
@Produces({MediaType.TEXT_HTML})
public String viewHome()
{
   return "<html>...</html>";
}

what I want to do is return home.html itself and not copying its contents and returning the string instead.

How do I do this? thanks :)

You can just return an instance of java.io.InputStream or java.io.Reader — JAX-RS will do the right thing.

@GET
@Produces({MediaType.TEXT_HTML})
public InputStream viewHome()
{
   File f = getFileFromSomewhere();
   return new FileInputStream(f);
}
