Unable to insert datetimeoffset value using Spring Boot, on SQL Server 2016

问题

I have this POJO:

public class SomeEntity {
    private String recordName;
    private Instant recordDatetime;

    public SomeEntity(String recordName, Instant recordDateTime) {
        this.recordName = recordName;
        this.recordDateTime = recordDateTime;
    }

    // Getters and Setters
}

...and this corresponding database table defined in a SQL Server 2016 database:

CREATE TABLE [dbo].[some_entities](
    [record_name] [nvarchar](255) NOT NULL,
    [record_datetime] [datetimeoffset](7) NOT NULL,
 CONSTRAINT [PK_some_entities] PRIMARY KEY CLUSTERED 
(
    [record_name] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON),
)
GO

I have a DAO implementation class bean defined in my Spring Boot application that inserts a record into this table and reads records off the table. I am having a couple of problems though.

• The insert fails with the exception:

  com.microsoft.sqlserver.jdbc.SQLServerException: The conversion from UNKNOWN to UNKNOWN is unsupported.

  at com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement.setObject(SQLServerPreparedStatement.java:1329)
  

• Retrieving the records from the database via the getSomeEntities() method is throwing an exception too:

  nested exception is java.sql.SQLFeatureNotSupportedException: This operation is not supported.

The DAO implementation class is as follows:

@Repository
public class SomeEntityDaoImpl implements SomeEntityDao {

    @Autowired
    private NamedParameterJdbcTemplate jdbcTemplate;

    @Override
    public void insertNewRecord(SomeEntity someEntity) throws Exception {

        Map<String,Object> namedParameters = new HashMap<>();
        namedParameters.put("record_name", someEntity.getRecordName());
        namedParameters.put("record_datetime", someEntity.getRecordDatetime());
        try {

            int returnVal = jdbcTemplate.update("INSERT INTO some_entities (record_name, record_datetime) VALUES (:record_name, :record_datetime)", namedParameters);
            if (returnVal != 1) {
                logger.error("Could not insert into database: {} record(s) updated", returnVal);
                throw new Exception("insertion failed");
            }
        }
    }

    @Override
    public List<SomeEntity> getSomeEntities() throws Exception {

        List<SomeEntity> someEntities = new ArrayList<>();
        try {

            someEntities = jdbcTemplate.query("SELECT * FROM some_entities", (resultSet, rowNum) -> {

                SomeEntity someEntity = new SomeEntity(
                resultSet.getString("record_name"),
                resultSet.getObject("record_datetime", Instant.class));

                return someEntity;
            });
        } catch (DataAccessException dae) {
            logger.error("Failed to get some entities: {}", dae.getMessage(), dae);
            throw new Exception("Database exception");
        }

        return someEntities;
    }
}

I got the start from another comprehensive StackOverflow answer, but since it was not specific to Spring JDBC, I am not sure if I am following the suggested approach correctly.
