How to parse a json file into a java POJO class using GSON -

i using gson parse json file , want map json object pojo class. problem property name in json doesn't have camel-case java pojo object having camel-case property name.

is there idea without having performance hit?

eg: attribute name in json file 'ordernumber', in pojo class , instead ordernumber, have 'salesnumber' attribute name. how can map ordernumber json salesnumber of pojo class?

thanks in advance!

you can use @serializedname annotation in case.

private class someobject {    @serializedname("ordernumber")    private string salesnumber;  }
