相关代码如下：

/**(非 Javadoc)
   * <p>Description(描述):根据员工的姓名查询员工信息 </p>
   * <p>Title: queryInfoByName</p>
   * @param name
   * @return
   * @see org.dao.IEmpDao#queryInfoByName(java.lang.String)
   */
  @Override
  public Emp queryInfoByName(String name) {
    
    
    Emp emp = null;
    String hql = " from Emp where ename = ?";
    Session session = this.getSession();
    List<Emp> empList  =  session.createQuery(hql)
                .setParameter(1, name)
                .list();
    if(empList.size()!=0){
      emp = empList.get(0);
    }
    return emp;
  }

注意看这里：

setParameter(1, name)

很明显，这个地方的1应该改成0，但是我原来就是0来着，网上有人说要改成1.。。。。。。我以为我记错了？想着反正也是个错，何不试试呢。于是就二了起来试了试，也许之前越界是其他的原因，改到后面居然忘了到底改哪里了，于是乎把1重新改成了0之后终于可以用了。

setParameter(1, name)

正确详细代码如下：

/**(非 Javadoc)
   * <p>Description(描述):根据员工的姓名查询员工信息 </p>
   * <p>Title: queryInfoByName</p>
   * @param name
   * @return
   * @see org.dao.IEmpDao#queryInfoByName(java.lang.String)
   */
  @Override
  public Emp queryInfoByName(String name) {
    
    
    Emp emp = null;
    String hql = " from Emp where ename = ?";
    Session session = this.getSession();
    List<Emp> empList  =  session.createQuery(hql)
                .setParameter(0, name)
                .list();
    if(empList.size()!=0){
      emp = empList.get(0);
    }
    return emp;
  }
