Spring JDBC Template: Can't infer the SQL type to use for an instance - spring

Question

I'm using a jdbcTemplate query to return a list of a custom object, but I'm receiving the error "org.postgresql.util.PSQLException: Can't infer the SQL type to use for an instance of [Ljava.util.UUID;."
Here's the object type that I want to get back from my query:
data class BasicUser(
var convoId: Long,
var firstName: String,
var lastName: String,
var imageUrl: String?
)
I made this class for use in my query:
class ConversationMapper: RowMapper<BasicUser> {
override fun mapRow(rs: ResultSet, rowNum: Int): BasicUser {
return BasicUser(
convoId = rs.getLong("convo_id"),
firstName = rs.getString("first_name"),
lastName = rs.getString("last_name"),
imageUrl = rs.getString("image_url")
)
}
}
And here's the query that's erroring out:
fun getConversations(id: UUID){
val sql = "SELECT first_name, last_name, convo_id, image_url FROM users u cross join conversations c where c.user_id1::uuid = ? or c.user_id2::uuid = ?"
val res = jdbcTemplate.query(sql, ConversationMapper(), arrayOf(id, id))
}
I already know this is a valid query, so that's not the issue. I've tried a few combinations of things to resolve this with no luck. Please help, I'm stuck.
I did another query that also used a UUID, so I'm confused as to why UUID seems to be the issue. Here's that successful query:
fun findConversationsById(id: UUID): List<Long> {
return jdbcTemplate.queryForList("SELECT convo_id FROM conversations WHERE user_id2=? or user_id1=?", arrayOf<Any>(id, id), Long::class.java).toList()
}
Here's the full stack trace:

Answer 1

I think You should make 2 things:
Give :param in SQL
Select proper object into queryForList
Example:
protected static List<Map<String, Object>> getFolderListIds(Long documentId) {
String sql = "SELECT id FROM table WHERE id = :document_id"
MapSqlParameterSource parameters = new MapSqlParameterSource();
parameters.addValue("document_id", documentId);
NamedParameterJdbcTemplate namedParameterJdbcTemplate = new NamedParameterJdbcTemplate(Something.getDataSource());
return namedParameterJdbcTemplate.queryForList(sql, parameters);
}
