Mybatis数据添加返回主键返回为1的问题

<insert id="saveWorksReport" useGeneratedKeys="true" keyProperty="worksReportId" parameterType="com.supplychain.entity.WorksReport">
   <!-- <selectKey resultType="int" order="AFTER" keyProperty="worksReportId">
        SELECT LAST_INSERT_ID();
    </selectKey>-->
    insert into works_report (original_papers,user_id,works_id,start_date,report_detail,original_works_url) values
     (#{originalPapers},#{userId},#{worksId},now(),#{reportDetail},#{originalWorksUrl})

</insert>
第一种<insert id="saveWorksReport" useGeneratedKeys="true" keyProperty="worksReportId" parameterType="com.supplychain.entity.WorksReport">
第二种
<selectKey resultType="int" order="AFTER" keyProperty="worksReportId">
        SELECT LAST_INSERT_ID();
</selectKey>

WorksReport worksReport = new WorksReport();

Integer saveWorksReport = worksReportMapper.saveWorksReport(worksReport);
之前的代码返回的是saveWorksReport所以一直是1，正确返回应该是worksReport.getWorksReportId();
