无法将hibernate结果集格式化为正确的json

Question

我遇到了与使用Jackson将Hibernate结果集转换为JSON相关的问题。我使用以下语句从数据库中获取记录。

List<IndoorRegister> indoorRegister = entityManager.createQuery("select indoorId, srnoPart1, srnoPart2, dateOfAdmit, dateOfDischarge, patientName, address, age, diagnosis, treatment, fees, remarks, createDate, modifyDate from IndoorRegister").getResultList()

之后，我使用下面的行将列表转换为json

ObjectMapper mapper = new ObjectMapper();
List<IndoorRegister> allIndoorEntries = indoorRegisterService.getIndoorRegister();
String jsonForm = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(allIndoorEntries)

然而，字符串形式的JSON返回类似于

的内容

[[ 1, "03122014", "01", 1417545000000, 1417977000000, "test", "sdfg", 20, "Diagnosis - 3", "MTP", 12.23, "sdg", 1418110332000, 1418110332000 ], [ 2, "09122014", "01", 1418063400000, 1418754600000, "test", "test", 18, "Diagnosis - 3", "Tubectomy", 12.23, "sf", 1419486569000, 1419486569000 ], [ 3, "09122014", "2", 1418063400000, 1418668200000, "sfsafd", "asdfsa", 19, "Diagnosis - 3", "MTP", 12.32, "sadf", 1419527458000, 1419527458000 ], [ 4, "10122014", "1", 1418149800000, 1418668200000, "sfsafd", "asdfsa", 19, "Diagnosis - 3", "MTP", 12.32, "sadf", 1419527509000, 1419527509000 ]]

我的要求是将包含json的字符串和值返回为 -

[{"indoorId":1,"srnoPart1":"12262014","srnoPart2":"01","dateOfAdmit":1419655160683,"dateOfDischarge":1419655160683,"patientName":"abc","address":"any add","age":16,"diagnosis":"diagnosis","treatment":null,"fees":12.23,"remarks":"test","createDate":1419655160683,"modifyDate":1419655160683}, {"indoorId":2,"srnoPart1":"12262014","srnoPart2":"02","dateOfAdmit":1419655160683,"dateOfDischarge":1419655160683,"patientName":"abc","address":"any add","age":16,"diagnosis":"diagnosis","treatment":null,"fees":12.23,"remarks":"test","createDate":1419655160683,"modifyDate":1419655160683}]
