Mybatis实现单个和批量定义别名typeAliases

  <insert id="saveCity" keyProperty="id" useGeneratedKeys="true" parameterType="com.jd.lgg.web.domain.city.City">
        insert into jd_am_visit_city(cityName,creationTime,updateTime,yn)
        values(#{cityName},now(),now(),1)
    </insert>

   <insert id="saveCity" keyProperty="id" useGeneratedKeys="true" parameterType="city">
        insert into jd_am_visit_city(cityName,creationTime,updateTime,yn)
        values(#{cityName},now(),now(),1)
    </insert>
