How to get mustache html in java

Question

I'm trying to use mustache to fill an html for me, then i want to get that html and use it as String.

A template like this -> template.xhtml

<table style="width:10%" align="center">
    <tr>
        <th>Old</th>
        <th>New</th>
    </tr>
    <tr>
        <td>{{old}}</td>
        <td>{{new}}</td>                                
    </tr>
</table>

With a Hash like this:

HashMap<String, String> scopes = new HashMap<String, String>();
    scopes.put("old", "Testing");
    scopes.put("new", "Mustache");

Now how do i tell, Mustache to use template.xhtml and fill with scopes and then return me the html?

Answer 1

Take a look at the very bottom of the Mustache project's readme file (https://github.com/spullara/mustache.java#readme). There's an example main method there that does almost exactly what you need. Just use a StringWriter instead of an OutputStreamWriter so that you can get the resulting HTML as a String.

I am using the spring starter mustache.

      <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mustache</artifactId>
            <version>2.1.6.RELEASE</version>
        </dependency>

MustacheResourceTemplateLoader loader = new MustacheResourceTemplateLoader("emailTemplates/", ".html");   // Inside resources emailTemplates dir

        Reader reader = loader.getTemplate("index");
        Template tmpl = Mustache.compiler().compile(reader);
// Template String "One, two, {{three}}. Three sir!"
        Map<String, String> data = new HashMap<String, String>();
        data.put("three", "six");

I hope this helps.
