报错：java.sql.SQLException: Parameter index out of range (4 > number of parameter，which is 3)

 Mybatis查询两张表数据统计结果，报错:java.sql.SQLException: Parameter index out of range (4 > number of parameter，which is 3)

   /* select u.id,u.login_name,u.photo,u.number_of_fans,u.number_of_followers,count(e.id) essayCount
    from tb_user u right join tb_hobbies e on u.id =e.user_id
    where u.id = #{userId} and e.state = 2*/
    select u.id,u.login_name,u.photo,u.number_of_fans,u.number_of_followers, count(1) essayCount
    from (select h.id from tb_user u right join tb_hobbies h on u.id =h.user_id
          where u.id = #{userId} and h.state = 2
          union all
          select e.id
          from tb_user u right join tb_essay e on u.id =e.user_id
          where u.id = #{userId} and e.state = 2
    ) as c,tb_user u
    where u.id = #{userId}

解决：注释错了！！！！！在mapperDao.xml中不能用/**/注释,应该为

   
    select u.id,u.login_name,u.photo,u.number_of_fans,u.number_of_followers, count(1) essayCount
    from (select h.id from tb_user u right join tb_hobbies h on u.id =h.user_id
          where u.id = #{userId} and h.state = 2
          union all
          select e.id
          from tb_user u right join tb_essay e on u.id =e.user_id
          where u.id = #{userId} and e.state = 2
    ) as c,tb_user u
    where u.id = #{userId}

或者直接去掉！！！
