Spring Boot: Can't infer the SQL type to use for an instance of java.time.LocalDateTime

Question

I have the following method (full JdbcInvoiceRepository class below) executed in a Spring Boot project:

public int[] bulkSaveInvoices(List<Invoice> invoices){

    String insertSQL = "INSERT INTO invoices VALUES (:id, :exactIssueTime, :finalIssueTime, :issuer, :groupID)";
    SqlParameterSource[] sqlParams = SqlParameterSourceUtils.createBatch(invoices.toArray());

    int[] insertCounts = namedParameterJdbcTemplate.batchUpdate(insertSQL, sqlParams);

    return insertCounts;
}

I have provided the converters in :

├── Invoice.java
├── InvoiceRepository.java
└── persistance
    ├── converters
    │   ├── LocalDateAttributeConverter.java
    │   └── LocalDateTimeAttributeConverter.java
    └── JdbcInvoiceRepository.java

COnverter for LocalDateTime:

@Converter(autoApply = true)
public class LocalDateTimeAttributeConverter implements AttributeConverter<LocalDateTime, Timestamp> {

    @Override
    public Timestamp convertToDatabaseColumn(LocalDateTime locDateTime) {
        return (locDateTime == null ? null : Timestamp.valueOf(locDateTime));
    }

    @Override
    public LocalDateTime convertToEntityAttribute(Timestamp sqlTimestamp) {
        return (sqlTimestamp == null ? null : sqlTimestamp.toLocalDateTime());
    }
}

However when I execute it in test I keep getting the error:

org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [INSERT INTO invoices VALUES (?, ?, ?, ?, ?)]; nested exception is org.postgresql.util.PSQLException: Can't infer the SQL type to use for an instance of java.time.LocalDateTime. Use setObject() with an explicit Types value to specify the type to use.

What can be the issue and how to fix this?

JdbcInvoiceRepository

@Repository
public class JdbcInvoiceRepository {

    @Inject
    private JdbcTemplate jdbcTemplate;
    @Inject
    private NamedParameterJdbcTemplate namedParameterJdbcTemplate;

    private SimpleJdbcInsert simpleJdbcInsert;

    @PostConstruct
    public void setupSimpleJdbcInsert(){
        simpleJdbcInsert =
                new SimpleJdbcInsert(jdbcTemplate).withTableName("invoices").usingGeneratedKeyColumns("id");
    }

    public int[] bulkSaveInvoices(List<Invoice> invoices){

        String insertSQL = "INSERT INTO invoices VALUES (:id, :exactIssueTime, :finalIssueTime, :issuer, :groupID)";
        SqlParameterSource[] sqlParams = SqlParameterSourceUtils.createBatch(invoices.toArray());

        int[] insertCounts = namedParameterJdbcTemplate.batchUpdate(insertSQL, sqlParams);

        return insertCounts;
    }

    public Long getInvoiceCount() {
        return jdbcTemplate.queryForObject("select count(*) from invoices",
                Long.class);

    }

}

EDIT Invoice.java

@Data
@AllArgsConstructor

@Entity
@Table(name = "invoices")
public class Invoice {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    Long id;

    @Column(name = "exact_iss_time")
    private LocalDateTime exactIssueTime;

    @Column(name = "final_iss_time")
    private LocalDateTime finalIssueTime;

    @Column(name = "issuer")
    private String issuer;

    @Column(name = "groupid")
    private Integer groupID;

    protected Invoice() {
    }

}

Invoice table definition:

    CREATE TABLE invoices (
  id      SERIAL PRIMARY KEY,
  exact_iss_time TIMESTAMP NOT NULL,
  actual_iss_time TIMESTAMP NOT NULL,
  issuer    TEXT NOT NULL,
  groupid   INTEGER NOT NULL
);

So you are using a `JdbcTemplate` and you expect something from the JPA library to help you there.... Although both persistence technologies (and very low-level they have a link) they don't work together like you expect. — M. Deinum, Mar 16 '17 at 13:39
@Cassian This solution not work. Also I have those converters mentioned in first post. — mCs, Mar 24 '17 at 06:37

1) Don't use JDBC to try and bulk save JPA entities

2) Use Spring Data JPA instead

3) Define a Spring Data Repository as so:

public interface InvoiceRepository  extends JpaRepository<Invoice, Long> {}

4) call the save (Iterable iterable method on your repository and let JPA handle all the ORM tasks for you.

e.g. invoiceRepository.save(invoices)

I wanted to use `JDBCTemplate` because this code is for data generator of approx 500M records and I believe that this way it might be more efficient to use low evel `JDBCtemplate` – mCs Mar 24 '17 at 18:54
