For example, I want to generate a json string for ng-style:

<th ng-style="{width:247}" data-field="code">Code</th>

But with jackson, the result is:

<th ng-style="{&quot;width&quot;:247}" data-field="code">Code</th>

It's not easy to read.

So I want jackson to generate the json string with single quote or no quotes. Is it possible to do this?

If you have control over the ObjectMapper instance, then configure it to handle and generate JSON the way you want:

final ObjectMapper mapper = new ObjectMapper();
mapper.configure(JsonGenerator.Feature.QUOTE_FIELD_NAMES, false);
mapper.configure(JsonParser.Feature.ALLOW_UNQUOTED_FIELD_NAMES, true);
