java - What syntax would I use to have my program disregard underscores, punctuation, and all other camelcase etc -

i using jackson library. have added in dependencies.

here syntax have used far, have passed in object method called result.

 private void getsamplefromjson(list<sampleprojectdto> result) throws jsonparseexception, jsonmappingexception, ioexception {   url url = this.getclass().getresource("/test.json");   file jsonfile = new file(url.getfile());   system.out.println("full path of file: " + jsonfile);    objectmapper mapper = new objectmapper();   inputstream = test_project.class.getresourceasstream("/test.json");   sampledto testobj = mapper.readvalue(is, sampledto.class);   system.out.println(testobj.getcreatedbyurl()); 

}

now file reading, file text file json in it. problem lot of variables , things in file have underscores, , in camel case, , causing program not run. can not have change entire json file, there programming method or statement can put in have ignore these punctuations , camel case , make nice , snake case method able work , program?

i might not understand concrete problem have, mapping pojo fields json properties can done follows.

you either have use jsonproperty annotation:

class sampledto{     @jsonproperty("first_name")  // property name json     protected string firstname;     protected string getfirstname(){return firstname;} } 

or configure objectmapper propertynamingstrategy:

mapper.setpropertynamingstrategy(     propertynamingstrategy.camel_case_to_lower_case_with_underscores); 

you can implement own propertynamingstrategy if want, it's you.
