How to use json with Handlebars.java

handlebars.js, java

Solution

Just found out that passing the json as JsonNode object works.

public class TestHandlebars {
    public static void main(String[] args) throws Exception {
        String json = "{\"name\": \"world\"}";
        JsonNode jsonNode = new ObjectMapper().readValue(json, JsonNode.class);
        Handlebars handlebars = new Handlebars();
        handlebars.registerHelper("json", Jackson2Helper.INSTANCE);

        Context context = Context
            .newBuilder(jsonNode)
            .resolver(JsonNodeValueResolver.INSTANCE,
                    JavaBeanValueResolver.INSTANCE,
                    FieldValueResolver.INSTANCE,
                    MapValueResolver.INSTANCE,
                    MethodValueResolver.INSTANCE
            )
            .build();
        Template template = handlebars.compileInline("Hello {{name}}!");
        System.out.println(template.apply(context));
    }
}

Problem

I am trying to use handlebars.java to apply json data. I took the below example from https://github.com/jknack/handlebars.java where it was for handlebars.js and I expect the same will work in handlebars.java ``` public class TestHandlebars { public static void main(String[] args) throws Exception { String json = "{\"name\": \"world\"}"; Handlebars handlebars = new Handlebars(); handlebars.registerHelper("json", Jackson2Helper.INSTANCE); Context context = Context .newBuilder(json) .resolver(JsonNodeValueResolver.INSTANCE, JavaBeanValueResolver.INSTANCE, FieldValueResolver.INSTANCE, MapValueResolver.INSTANCE, MethodValueResolver.INSTANCE ) .build(); Template template = handlebars.compileInline("Hello {{name}}!"); System.out.println(template.apply(context)); } } ``` I am expecting the output as Hello world! whereas I am getting just Hello ! What am I missing? I have seen the examples like with Jackson views with java model "Blog" at https://github.com/jknack/handlebars.java, but can't this be achieved without using java model objects for that json?
