hibernatetemplate はbulkUpdate
実際に実行していbulkUpdate
ますか? コードを見たところ、実行していないようですbulkUpdate
。または多分私は何かを逃していますか?
public int bulkUpdate(final String queryString, final Object... values) throws DataAccessException {
return executeWithNativeSession(new HibernateCallback<Integer>() {
public Integer doInHibernate(Session session) throws HibernateException {
Query queryObject = session.createQuery(queryString);
prepareQuery(queryObject);
if (values != null) {
for (int i = 0; i < values.length; i++) {
queryObject.setParameter(i, values[i]);
}
}
return queryObject.executeUpdate();
}
});
}
一方、JdbcTemplate batchUpdate
(のように見える)はbatchUpdate
public int[] batchUpdate(final String[] sql) throws DataAccessException {
Assert.notEmpty(sql, "SQL array must not be empty");
if (logger.isDebugEnabled()) {
logger.debug("Executing SQL batch update of " + sql.length + " statements");
}
class BatchUpdateStatementCallback implements StatementCallback<int[]>, SqlProvider {
private String currSql;
public int[] doInStatement(Statement stmt) throws SQLException, DataAccessException {
int[] rowsAffected = new int[sql.length];
if (JdbcUtils.supportsBatchUpdates(stmt.getConnection())) {
for (String sqlStmt : sql) {
this.currSql = sqlStmt;
stmt.addBatch(sqlStmt);
}
rowsAffected = stmt.executeBatch();
}
else {
for (int i = 0; i < sql.length; i++) {
this.currSql = sql[i];
if (!stmt.execute(sql[i])) {
rowsAffected[i] = stmt.getUpdateCount();
}
else {
throw new InvalidDataAccessApiUsageException("Invalid batch SQL statement: " + sql[i]);
}
}
}
return rowsAffected;
}
public String getSql() {
return this.currSql;
}
}
return execute(new BatchUpdateStatementCallback());
}
