Bean property 'feedId' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

问题

Below is code Batch snippet: XML : </beans:property> -->

<beans:bean id="RDFieldSetMapper" class="in.gov.tds.batch.mapper.RDFieldSetMapper"
    autowire="byName" scope="step">
    <!-- <beans:property name="feedId" value="429717"></beans:property> -->
    <beans:property name="feedId" value="#{jobParameters[feedId]}"></beans:property>
</beans:bean>

setter method in Java Class:

recordDetail.setFeedId(new Long(feedId));

Please provide the resolution as I am getting Invalid setter method.

More Mapper detail: public class RDFieldSetMapper implements FieldSetMapper {

private Long feedId;
private int batchCounter;

@Override
public RecordDetail mapFieldSet(FieldSet fieldSet) throws BindException {
    if (LOGGER.isDebugEnabled())
        LOGGER.debug("Record Detail Mapper:-- " + " " + fieldSet);

    RecordDetail recordDetail = new RecordDetail();

    // feedId = FeedReader.feedId;
    recordDetail.setFeedId(new Long(feedId));
    }

}

回答1:

solved the problem. Issue : setter and getter methods are not present in the mapper class.

public Long getFeedId() {
    return feedId;
}

public void setFeedId(Long feedId) {
    this.feedId = feedId;
}
