<select id="getElementByCondition"  resultType="Activity">
        select
        user.name as owner,
        act.name,
        act.startDate,
        act.endDate
         from tbl_activity act
        join tbl_user user
        on act.owner = user.id
        <where>
            
            <if test="act.owner != null and act.owner != ''">
                and act.endDate &lt; #{endDate}

        </where>
        order by act.startDate
        limit #{skipCount},#{pageSize}
        
    </select>

 该查询语句的条件应该为判断endDate,此处判断的条件写成了owner的判断条件,而非endDate,导致如果该字段为空时,无法跳过该语句,,此时endDate为空时会有空指针异常...................

解决==============
在pom文件中plugins标签中添加
 <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
        </resources>
