与其创建和传递JsonDataSource，不如将JSON数据流直接传递给json查询执行器(通过<queryString language="json">在报表中使用)：

代码语言：javascript
运行
复制
    Map<String, Object> parameters = new HashMap<>();
    parameters.put(JsonQueryExecuterFactory.JSON_INPUT_STREAM, stream);
    JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters);
