问题：
使用springMVC将文件夹上载到mysql时出错
柳飞鸾
我正在构建一个应用程序。用户将查看一个页面，用户应该输入患者代码，以及以下描述，然后，用户将上传包含CSV文件的文件夹。我正在尝试使用spring MVC - JSP上传“一个包含CSV文件的文件夹”(不是zip/rar文件)
这是我的JSP代码:
<div class="w3-row w3-section">
<div class="w3-col" style="width:200px">* Patient code</div>
<div class="w3-rest">
<%--<form:select path="patient">--%>
<%--<form:options items="${patient}" itemLabel="name" itemValue="id"/>--%>
<%--</form:select>--%>
<form:input type="text" path="id_patient" name="id_patient" id="id_patient" placeholder="input number 1-20" class="w3-input w3-border"/>
</div>
</div>
<div class="w3-row w3-section">
<div class="w3-col" style="width:200px">* Patient description</div>
<div class="w3-rest">
<form:input type="text" path="description" name="description" id="description" placeholder="put any description" class="w3-input w3-border"/>
</div>
</div>
<div class="w3-row w3-section">
<div class="w3-col" style="width:200px">* Input Data Files</div>
<div class="w3-rest">
<input type="file" path="fileName" name="attachFileObj" webkitdirectory directory />
</div>
</div>
这是我的患者.java文件：
public class Patient {
//field patient
private int id_patient;
private String description;
private String patient;
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public int getId_patient() {
return id_patient;
}
public void setId_patient(int id_patient) {
this.id_patient = id_patient;
}
public String getPatient() {
return patient;
}
}
这是我的附件.java类：
package com.Patient.pojo;
public class Attachment {
//field attachment
private int id_data;
private byte[] data;
private String fileName;
private int patientID;
public int getId_data() {
return id_data;
}
public void setId_data(int id_data) {
this.id_data = id_data;
}
public byte[] getData() {
return data;
}
public void setData(byte[] data) {
this.data = data;
}
public int getPatientID() {
return patientID;
}
public void setPatientID(int patientID) {
this.patientID = patientID;
}
}
这是我的dao文件:
@Override
public void saveAttachment(Patient patient, Attachment attachment) {
if(null != jdbcTemplate) {
// Performing The Sql 'Insert' Operation
String sql = "insert into patient(id_patient, description) values(?,?);" +
"insert into attachment(id_data, file_data, patientID) values (?, ?, (select patientID from patient where patientID = id_patient));";
jdbcTemplate.update(sql, patient.getDescription(), attachment.getId_data(), attachment.getData(), attachment.getPatientID());
// int insertCount = jdbcTemplate.update(sql, patient.getData());
// if(insertCount == 1) {
// System.out.println("The Uploaded File Is Successfully Saved In The Database...!" + "\n");
// } else {
// System.out.println("Error Occured While Saving The Uploaded File In The Database... Please Check...!" + "\n");
// }
} else {
System.out.print("Application Is Not Able To Bind With The Database! Please Check!");
}
}
这是Dao文件中的类映射器：
class PatientMapper implements RowMapper<Patient> {
public Patient mapRow(ResultSet rs, int arg1) throws SQLException {
Patient patient = new Patient();
patient.setId_patient(rs.getInt("id_patient"));
patient.setDescription(rs.getString("description"));
Attachment attachment = new Attachment();
attachment.setId_data(rs.getInt("id_data"));
attachment.setData(rs.getBytes("file_data"));
attachment.setPatientID(rs.getInt("patientID"));
return patient;
}
}
这是我处理保存文件的控制器:
@RequestMapping(value = "/AddPatient/{reqUserName}/add", method = RequestMethod.POST)
public ModelAndView saveAddPatient(@ModelAttribute("patient") Patient patient,
Attachment attachment,
@PathVariable String reqUserName,
SessionStatus status,
HttpServletRequest request,
final @RequestParam CommonsMultipartFile[] attachFileObj)
throws IllegalStateException, IOException {
// Determine If There Is An File Upload. If Yes, Attach It To The Client Email
if ((attachFileObj != null) && (attachFileObj.length > 0) && (!attachFileObj.equals("")) &&
(patient != null)) {
for (CommonsMultipartFile aFile : attachFileObj) {
if(aFile.isEmpty()) {
continue;
} else {
System.out.println("Attachment Name?= " + aFile.getOriginalFilename() + "\n");
if (!aFile.getOriginalFilename().equals("")) {
patient = new Patient();
patient.setDescription(patient.getDescription());
attachment = new Attachment();
attachment.setData(aFile.getBytes());
// patient.setFileName(aFile.getOriginalFilename());
// Calling The Db Method To Save The Uploaded File In The Db
patientService.saveAttachment(patient, attachment);
}
}
System.out.println("File Is Successfully Uploaded & Saved In The Database.... Hurrey!\n");
}
} else {
// Do Nothing
}
modelViewObj = new ModelAndView("success_Add_Patient","messageObj","Thank You! The File(s) Is Successfully Uploaded!");
return modelViewObj;
}
当我运行代码并想通过上传文件夹来添加文件时，我得到了这个错误:

这是数据库中的表：
任何人都可以帮助我，如何解决这个问题？以便我可以将csv文件组成的文件夹上传到数据库mysql？
共有2个答案

插入sql有很多地方需要更改：
a.当使用< code>INSERT INTO时，只能使用< code>SELECT，在这种情况下，还需要删除关键字< code >值
b.需要删除<代码>；在sql的结尾
c.不能在一个sql中执行两个< code>INSERT INTO
所以改变
String sql = "insert into patient(id_patient, description) values(?,?);"
+ "insert into attachment(id_data, file_data, patientID) values (?, ?, (select patientID from patient where patientID = id_patient));";
到两个单独的sql
String sqlA = "insert into patient(id_patient, description) values(?,?)";
String sqlB = "insert into attachment(id_data, file_data, patientID)
values(?,?,?);
在这种情况下，您需要为每个 sql 调用 jdbcTemplate.update（） 两次
司马高昂
我不认为您可以同时运行这两个：
if(null != jdbcTemplate) {
// Performing The Sql 'Insert' Operation
String sql = "insert into patient(id_patient, description) values(?,?);" +
"insert into attachment(id_data, file_data, patientID) values (?, ?, (select patientID from patient where patientID = id_patient));";
jdbcTemplate.update(sql, patient.getDescription(), attachment.getId_data(), attachment.getData(), attachment.getPatientID());
也许可以尝试：
if(null != jdbcTemplate) {
// Performing The Sql 'Insert' Operation
String sql = "insert into patient(id_patient, description) values(?,?);";
String sqlTwo = "insert into attachment(id_data, file_data, patientID) values (?, ?, (select patientID from patient where patientID = id_patient));";
jdbcTemplate.update(sql, patient.getDescription(), attachment.getId_data(), attachment.getData(), attachment.getPatientID());
jdbcTemplate.update(sqlTwo, patient.getDescription(), attachment.getId_data(), attachment.getData(), attachment.getPatientID());
也
不能用嵌套子查询绑定参数:
values (?, ?, (select patientID from patient where patientID = id_patient))
