ResultSet may only be accessed in a forward direction 问题解决

  if(this.rs.isFirst()){
    this.rs.last();//抛该异常
    PropertiesUtil.setProperty("UpdateUserInfo.beginTime", df2.format(df.parse(this.getFieldValue(17).toString())));
    this.rs.first();

 }

原因：默认mssql链接是不支持游标操作

修改如下：

将

this.stmt = this.conn.createStatement();

改为

this.stmt = this.conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY);
