springMVC支持jsonp

@RequestMapping("directives.json")
@ResponseBody
public MappingJacksonValue directives(String callback) {
    MappingJacksonValue mappingJacksonValue = new MappingJacksonValue("you can put everything here.");
    mappingJacksonValue.setJsonpFunction(callback);
    return mappingJacksonValue;
}
