我在嘗試從JSON文件獲取數據時遇到了麻煩。我的JAVA端正在工作，但是在組裝JSON的PHP中進行了更改，因為我無法執行解析器，因此我不知道在PHP中知道我正在獲取的JSON格式，但是我可以訪問代碼。JSON掛載的頁面是這樣的：<?php $startTime = microtime(true); include_once("../utils/config.php"); include_once("../utils/utils.php"); include_once("../services/rest.utils.php"); header("Content-Type: application/json",true); $from = getADate('from', true); $to = getADate('to', false); $fromDate = ''; $toDate = ''; if ($from <> '') { $fromDate = $from; } if ($to <> 'NULL') { $toDate = $to; } $body = file_get_contents('php://input'); if (signatureCheck($body)) { $cta = 0; $database = conectaDatabase(); $script = ''; $pfx = Config::getPrefixo(); $sql = "SELECT RelatorioID, ProfessorID, AlunoID, TurmaID, Bimestre, Data, TipoRelatorio, Conteudo, Situacao FROM {$pfx}Relatorios WHERE Data >= $fromDate"; if ($toDate <> '') { $sql .= " AND Data < $toDate"; } $qry = $database->query($sql); $lista = array(); $cta = 0; while ($row = $qry->fetchObject()) { $row->TipoRelatorio = utf8_encode($row->TipoRelatorio); $row->Conteudo = utf8_encode($row->Conteudo); $lista[] = $row; $cta++; } @$output->response = new StdClass(); // Anonymous object, remove the warning $output->response->descricao = "$cta relatórios importados"; $output->response->status = 200; $output->relatorios = $lista; $endTime = microtime(true); $timeSpent = $endTime - $startTime; $output->response->timeSpent = $timeSpent; $saida = json_encode($output, JSON_UNESCAPED_UNICODE); echo $saida; desconectaDB($database); }

問題是您的JSON如下所示：
{
"response": {
...
},
"relatorios": [
{
...
}
]
}
您正在嘗試將其直接映射到relatorios列表。您應該RestResponse改為創建另一個對象。這應該包含整個JSON響應內容：
public class RestResponse {
private MyResponse response;
private List<RelatorioResponse> relatorios;
// getter and setter
}
該response對象應代表responseJSON中的部分。如果不需要，也可以添加@JsonIgnoreProperties(ignoreUnknown = true)到RestResponse類中并忽略response屬性：
@JsonIgnoreProperties(ignoreUnknown = true)
public static class RestResponse {
private List<RelatorioResponse> relatorios;
// getter and setter
}
您的請求代碼應如下所示：
HttpEntity<String> entity = new HttpEntity<>("parameters", new HttpHeaders());
ResponseEntity<RestResponse> response = new RestTemplate().exchange(targetUrl, HttpMethod.GET, entity, RestResponse.class);
List<RelatorioResponse> responses = response.getBody().getRelatorios();
