解决mybatisplus的分页插件和条件构造器自定义SQL遇到的BUG

mybatisplus的分页插件和条件构造器自定义SQL遇到的BUG

代码

Page<ScoreRecordListVO> getScoreRecordPages( @Param(Constants.WRAPPER) QueryWrapper<ScoreRecord> qw,@Param("pages") Page<ScoreRecordListVO> pages);

问题

当使用@Param("page")或其他时，会失效…

经过多方尝试，只能使用@Param("pages")

完整代码

• Mapper文件

package evan.lijun.xscj.mapper;

import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.baomidou.mybatisplus.core.toolkit.Constants;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;

@Repository
public interface ScoreRecordMapper extends BaseMapper<ScoreRecord> {
    Page<ScoreRecordListVO> getScoreRecordPages( @Param(Constants.WRAPPER) QueryWrapper<ScoreRecord> qw,@Param("pages") Page<ScoreRecordListVO> pages);
}

• 自定义SQL

<select id="getScoreRecordPages" resultType="evan.lijun.xscj.pojo.vo.ScoreRecordListVO">
	SELECT <include refid="getScoreRecordPagesSelect"></include> FROM score_record record
    LEFT JOIN student ON record.student_id = student.id -- 关联student表
    LEFT JOIN class_and_grade teams ON record.team_id = teams.id -- 关联class_and_grade表
    LEFT JOIN course ON record.course_id = course.id -- 关联course表
    ${ew.customSqlSegment}
</select>
