Spring REST consuming JSON uppercase vs lowercase

Question

I am trying to create simple webservice, that is reading JSON from URL and gives it back. I followed spring.io tutorial about this. I am probably missing something about naming conventions?

JSON I use doesn't have nice naming convention. Some values are in uppercase, some lowercase other are mixed. What I understood for proper matching with restTemplate I need to follow these names.

My object structure:

public class Page {
private String name; //works
private String about; // works
private String PHONE; //does not work
private String Website; //does not work

//getters and setters
}

If I change them to public, they start to work.

public class Page {
private String name; //works
private String about; // works
public String PHONE; //works
public String Website; //works

//getters and setters
}

This is the part of code where I use that

@RequestMapping(value = "/Test")
public Bubble getBubbleInfo(){
RestTemplate restTemplate = new RestTemplate();
Page page= restTemplate.getForObject("myURL", Page.class);
    return page;
}

What I am missing? It looks that using private required classical lowerUpper convention but if I change that it won't be properly matched with the JSON. Can I name it somehow for spring?

//spring, this is PHONE
public String phone;

Thanks a lot.

Solution

You can use @JsonProperty annotation to override the variable name.

@JsonProperty("phone")
public String PHONE;

Thanks, I tried that but in the result I had:both PHONE and phone. When I removed getters and setters it seems to be working. It means I should not have setters there? Or it is caused by something else?

have you added the annotation to the getter/setter method as well?

Basically, if its private then have getter and setter and annotate the variable declaration. Else, just annotating the variable declaration should fix it.

Thanks! This solution worked. Just put @JsonProperty annotation on variable, getters, and setters and your restful can consume as well as produce the uppercase!
