mybatis xml接收日期格式参数

news2025/2/25 6:25:15

实现方式一：

mapper

List<AsLLjgcfVO> selectjgcf(@Param("rq")Date rq)

mapper.xml

<select id="selectjgcf" parameterType="string" resultType="com.bysen.mes.domain.VO.AsLLjgcfVO">
where '${rq}' between t1.ks_day  and   t1.end_day
and '${rq}' between t2.ks_day  and   t2.end_day

实现方式二（推荐）在于接收参数的类型是date，参数类型是DATE

mapper.xml

<select id="selectjgcf" parameterType="date" resultType="com.bysen.mes.domain.VO.AsLLjgcfVO">
 SELECT  jhcb ,
    round(1000 * t1.jrbl * t2.sjdj/100,2) as sjcb
    from as_clcfb t1
    left join  as_cldjb t2 on t1.clmc = t2.clmc
    where #{rq,jdbcType=DATE} between t1.ks_day  and   t1.end_day
    and #{rq,jdbcType=DATE} between t2.ks_day  and   t2.end_day
    order by cllx
</select>

不指定参数类型，date是datetime，我们要的是日期，所以指定下参数类型更准确。

题外话

mapper.xml

 <insert id="insert" parameterType="com.hs.entity.A">
    insert into a (id, rq, create_time, 
      remark)
    values (#{id,jdbcType=INTEGER}, #{rq,jdbcType=DATE}, #{createTime,jdbcType=TIMESTAMP}, 
      #{remark,jdbcType=VARCHAR})
  </insert>
