My Class Productoresource where it burst array:

//Camada Rest
@RestController
@RequestMapping("/produtos")
public class ProdutoResource {
    // Acesso a camada Servico
    @Autowired
    private ProdutoService service;

    // Requisicao do id a ser buscado pelo metodo get
    @RequestMapping(value = "/{id}", method = RequestMethod.GET)
    public ResponseEntity<Produto> find(@PathVariable Integer id) {

        Produto obj = service.find(id);
        return ResponseEntity.ok().body(obj);

    }

    @RequestMapping(method=RequestMethod.GET)
    public ResponseEntity<Page<ProdutoDTO>> findPage(
            @RequestParam(value="nome", defaultValue="") String nome, 
            @RequestParam(value="categorias", defaultValue="") String categorias, 
            @RequestParam(value="page", defaultValue="0") Integer page, 
            @RequestParam(value="linesPerPage", defaultValue="24") Integer linesPerPage, 
            @RequestParam(value="orderBy", defaultValue="nome") String orderBy, 
            @RequestParam(value="direction", defaultValue="ASC") String direction) {
        String nomeDecoded = URL.decodeParam(nome);
        List<Integer> ids = URL.decodeIntList(categorias); ---- ERRO NESSA LINHA
        Page<Produto> list = service.search(nomeDecoded, ids, page, linesPerPage, orderBy, direction);
        Page<ProdutoDTO> listDto = list.map(obj -> new ProdutoDTO(obj));  
        return ResponseEntity.ok().body(listDto);
    }

Method URL.decodeIntList:

public static List<Integer> decodeIntList(String s) {
    String[] vet = s.split(",");
    List<Integer> list = new ArrayList<>();
    for (int i = 0; i < vet.length; i++) {
        list.add(Integer.parseInt(vet[1]));
    }
    return list;
}

The message says that the error was within the method URL.decodeIntList. Could you [Edit] your question and add the code of this method? Without knowing what he does, it is more difficult to guess the cause of the error - but in general ArrayIndexOutOfBoundsException: 1 indicates that you have an array with 1 position (i.e., only zero index) and somewhere the code is trying to access index 1 of this array.

Thanks for the help, follow the public code Static List<Integer> decodeIntList(String s) { String[] vet = s.split(","); List<Integer> list = new Arraylist<>(); for (int i = 0; i < vet.length; i++) { list.add(Integer.parseint(vet[1]); } Return list; }

I edited the question and added your code. But next time, you can [Edit] your question (it’s a common practice edit posts on this website). The code in the comments is not very readable (in question it is possible to format and is much better), and it is preferable that all the relevant information is in the question.

The problem lies within the for:

for (int i = 0; i < vet.length; i++) {
    list.add(Integer.parseInt(vet[1]));
}

Instead of taking the position of the array indicated by the loop (i), you are always picking up position 1 (vet[1]).

When the array has only one element, the only valid position will be zero (arrays start with zero index), and when trying to access position 1, the code will make an exception.

Just exchange vet[1] for vet[i]:

for (int i = 0; i < vet.length; i++) {
    list.add(Integer.parseInt(vet[i]));
}
