@HtmlDocConfig Annotation Basics

The @HtmlDocConfig annotation is used to customize the HTML view of POJOs serialized by HtmlDocSerializer.

It's used in the following locations:

For example, the following shows setting the title on a page:

@Rest
@HtmlDocConfig(
    title="My Resource Page"
)

The purpose of this annotation is to populate the HTML document view which by default consists of the following structure:

<html>
    <head>
        <style type='text/css'>
            CSS styles and links to stylesheets
        </style>
    </head>
    <body>
        <header>
            Page header
        </header>
        <nav>
            Navigation links
        </nav>
        <aside>
            Side-bar text
        </aside>
        <article>
            Contents of serialized object
        </article>
        <footer>
            Footer message
        </footer>
    </body>
</html>

The outline above is controlled by the HtmlDocTemplate interface which can be overridden via the @HtmlDocConfig(template) annotation.

The HelloWorldResource class was an example of the @HtmlDocConfig annotation in use:

// Sample REST resource that prints out a simple "Hello world!" message.
@Rest(
    path="/helloWorld",
    title="Hello World",
    description="An example of the simplest-possible resource"
)
@HtmlDoc(
    navlinks={
        "up: request:/..",
        "options: servlet:/?method=OPTIONS"
    },
    aside={
        "<div style='max-width:400px' class='text'>",
        "    <p>This page shows a resource that simply response with a 'Hello world!' message</p>",
        "    <p>The POJO serialized is a simple String.</p>",
        "</div>"
    }
)
@BeanConfig(sortProperties="true")
public class HelloWorldResource extends BasicRestServlet {

    @RestGet(path="/*", summary="Responds with \"Hello world!\"")
    public String sayHello() {
        return "Hello world!";
    }
}

SVL variables can be used in any of these annotations:

@Rest(
    path="/helloWorld",
    // Register a config file.
    config="MyConfig.cfg"
)
@HtmlDocConfig(
    navlinks={
        "up: request:/..",
        "options: servlet:/?method=OPTIONS",
        // Add a nav link to view the source code for this class.
        "source: $C{Source/gitHub}/org/apache/juneau/examples/rest/$R{servletClassSimple}.java"
    },
    aside={
        // Localize our messages.
        "<div style='max-width:400px' class='text'>",
        "    <p>$L{localizedMessage1}</p>",
        "    <p>$L{localizedMessage2}</p>",
        "</div>"
    }
)
public class HelloWorldResource extends BasicRestServlet {...}
