DustView

Server-Side Dust Rendering Support Library

Using DustTemplateEigine

    DustTemplateEngine engine = new DustTemplateEngine();
    
    // Compile Template
    String source = "Hello {name} World!";
    String compiled = engine.compile(source, "templateKey");
    
    // Load to Context
    engine.load(compiled);
    
    // Rendering to Text
    StringWriter writer = new StringWriter();
    engine.render(writer, "templateKey", "{\"name\":\"chanwook\"}");
    
    writer.getBuffer().toString()

Java Configuration

    @Configuration
    @EnableWebMvc
    @ComponentScan(basePackages = {"packageName"}, useDefaultFilters = false,
            includeFilters = {@ComponentScan.Filter(value = {Controller.class})})

XML Configuration

Refresh cache to template source

DustTemplateView is cache template file source for one time access to file. If you want to refresh template source, maybe redeploy your view source(dust compiled HTML), you call server with specific parameter(_refresh). Parameter value is "y" or "Y" (case insensitive).

    http://...?_refresh=y&.. or
    http://...?_refresh=Y&..

If you want that don't using caching, maybe development or test environment that frequently deploy view source(html), you possibly disable function. Default value is true(=caching)!

SimpleDustTemplateView.setViewCacheable(false);
