您必须使用max-rows-per-poll="0"：

   <xsd:attribute name="max-rows-per-poll" type="xsd:string">
                    <xsd:annotation>
                        <xsd:documentation>
                            When using a select query, you can set a
                            custom limit regarding the number of rows
                            extracted. Otherwise by default only the first
                            row will be extracted into the outgoing message.

                            If set to '0' all rows are extracted.
                        </xsd:documentation>
                    </xsd:annotation>
                </xsd:attribute>
