Error to get return of url in spring boot application with javascript

Question

I'm trying to get the return of the request in the url, with javascript, but I'm having problems.

I have the follow code:

Controller:

@GetMapping("/linguagens")
@ResponseBody
public Map<String, Linguagem> linguagens(){
    Map<String, Linguagem> linguagens = new HashMap<>();
    linguagens.put("linguagem", new Linguagem("Java", true));
    return linguagens;
}

HTML page:

            <button id="verLinguagens">Ver linguagens</button>
        <div id="linguagens">

        </div>

JavaScript code:

$('#verLinguagens').click(function (e) {
e.preventDefault();
$.get("/linguagens")
    .done(function (data) {
        $('#linguagens').html("Linguagens: " + data.linguagem)
        console.log(data.linguagem)
        console.log(data)
    });

});

In my page show the result, but show like this:

Linguagens: [object Object]

how can I show the correct result? like this

{
"Linguagem": {
    "nome": "Java",
    "compilada": true
}

}

Thanks!

It works!!

Linguagens: {"nome":"Java","compilada":true}

but, like this, I can put each value of key in some label? like, value "java" in label with id "javaLabel"?

You can use JSON.stringify(data) to convert the data to a json representation.

Would this give you what you're after?

var data = {
    "Linguagem": {
        "nome": "Java",
        "compilada": true
    }
};

console.dir(data);
var pretty = JSON.stringify(data, null, '\t');
document.getElementById('content').innerHTML = pretty;

<pre id="content"></pre>
