When use ShardingQueryAssistedEncryptor to find assistedQueryColumns, an outOfIndex exception will occur.

Here is the point:

ShardingEncryptorStrategy

/**
     * Get assisted query column.
     *
     * @param logicTableName logic table name
     * @param columnName column name
     * @return assisted query column
     */
    public Optional<String> getAssistedQueryColumn(final String logicTableName, final String columnName) {
        for (ColumnNode each : columns) {
            ColumnNode target = new ColumnNode(logicTableName, columnName);
            if (each.equals(target)) {
                return Optional.of(assistedQueryColumns.get(columns.indexOf(target)).getColumnName());
            }
        }
        return Optional.absent();
    }
