mybatis-plus中的@Select注解里面写sql语句的in

@Select("<script>" +
        "select \n" +
        "email \n" +
        "from sys_user\n" +
        "where id in \n" +
        "    <foreach item='item' index='index' collection='ids' open='(' separator=',' close=')'>" +
        "       #{item}" +
        "    </foreach>" +
        "</script>"
)
    List<String> listEmailByIdBatch(@Param("ids") List<String> ids);

比葫芦画瓢就成，注意ids的集合为String类型。
