java.sql.SQLFeatureNotSupportedException 在 org.sqlite.jdbc4.JDBC4PreparedStatement.setBinaryStream(JDBC4PreparedStatement.java :96)

Question

尝试将数据插入数据库。数据没有存储，我不明白这里有什么问题。

这些是要打印的错误消息的代码

        System.out.println(e.getErrorCode());
        System.out.println(e.getSQLState());
        System.out.println(e.getMessage());
        System.out.println(e.getCause());
        System.out.println(e.getNextException());

控制台出错

添加类以进一步了解详细信息。

CompanyDetailsController.java

    @FXML
private void saveCompanyDetails(ActionEvent event) throws IOException {

    String companyName = CompanyNameField.getText();
    String details = detailsField.getText();
    String address = addressField.getText();
    String country = countryField.getValue().toString();
    String city = cityField.getValue().toString();
    String state = stateField.getValue().toString();
    String stateCode = stateCodeField.getValue().toString();
    String pin = pinField.getText();
    String contactNumber = contactField.getText();

    String currency = currencyField.getText();
    String companyCode = companyCodeField.getText();
    String pos = posField.getText();

    fis= new FileInputStream(file);

    String sql = "INSERT INTO companyDetails (companyName, additionalDetails, address, country, city, state, stateCode, pinCode, contactNumber,"
            + "email, website,GSTIN, TAN,PAN, taxationType, taxRate, proprietor,adhaarNo,currency,companyCode,POScode,logo,cid) VALUES(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)";

    try {

        PreparedStatement pstmt = con.prepareStatement(sql);
        pstmt.setString(1, companyName);
        pstmt.setString(2, details);
        pstmt.setString(3, address);

        pstmt.setString(16, taxRate);
        pstmt.setString(17, proprietor);
        pstmt.setString(18, aadhaar);
        pstmt.setString(19, currency);
        pstmt.setString(20, companyCode);
        pstmt.setString(21, pos);
        pstmt.setBinaryStream(22,fis);


        pstmt.executeUpdate();

        hf.showDialog("Company Details Added Successfully");
    } catch (SQLException e) {

        System.out.println(e.getErrorCode());
        System.out.println(e.getSQLState());
        System.out.println(e.getMessage());
        System.out.println(e.getCause());
        System.out.println(e.getNextException());
    }
}

有人可以帮忙吗？

您可以在 github 中找到不支持 JDBC v4，包括一些特殊的 setter，例如 BLOB、二进制类型...

public void setBinaryStream(int parameterIndex, InputStream x, long length)
        throws SQLException {
    // TODO Support this
    throw new SQLFeatureNotSupportedException();
}

对于您在日志中遇到的问题，它正在使用 SQLFeatureNotSupportedException没有参数的构造函数。医生说:

Constructs a SQLFeatureNotSupportedException object. The reason, SQLState are initialized to null and the vendor code is initialized to 0. The cause is not initialized, and may subsequently be initialized by a call to the Throwable.initCause(java.lang.Throwable) method.
