方式一:
mybatis更新sql语句:
<update id="publishT00_notice" parameterType="Map">
update test
set createdate = #{createdate},
creator = #{creator}
where id in
<foreach collection="ids" item="ids" separator="," open="(" close=")">
#{ids}
</foreach>
</update>
传入map参数类型:
HashMap<String,Object> map = new HashMap<String, Object>();
map.put("creator", "creator");
map.put("createdate", "createdate");
String[] ids = {"1","2"};
map.put("ids", ids );
方式二:
第一步在你的mapper写上:
List<WeixinUserLocationList> findweixinUserLocations(@Param("params") Map<String, Object> map);
注意就是注解@param 这个,是mybatis的
然后在xml中这样写:
<if test="params.accountId!=null">
and a.accountid=#{params.accountId}
</if>
<if test="params.nickname!=null and params.nickname !=''">
and a.nickname like '%${params.nickname}%'
</if>
<if test="params.beginDate!=null and params.beginDate!=''">
and date_format(a.createtime,'%Y-%m-%d')>=${params.beginDate}
</if>
<if test="params.endDate!=null and params.endDate!=''">
<![CDATA[ and date_format(a.createtime,'%Y-%m-%d')<=${params.endDate} ]]>
</if>
${params.nickname}这种写法参数默认是传字符串,
#{params.accountId}可以取Long,Integer之类的。
