springboot、mybatis根据Ids数组来删除

今天学弟发qq给我说，参数为数组的删除不会。我整理一下，然后顺便写个博客随便粘贴。 service：

public boolean deleteEmpById(String ids) { String[] split = ids.split(","); return empMapper.deleteEmpById(split) == split.length; }

mapper接口：

/** * 删除employee * * @param ids * @return */ int deleteEmpById(@Param("ids") String[] ids);

mapper.xml

<delete id="deleteEmpById"> DELETE FROM employee WHERE id IN <foreach collection="ids" separator="," open="(" close=")" item="id"> #{id} </foreach> </delete>
