使用 getJdbcTemplate().query方法出现error code [17004] 无效的列类型
今天在使用JdbcDaoSupport的以下方法
getJdbcTemplate().query(String sql,Object[] args,ResultSetExtractor rse)
时出现错误，看了很久才发现原来不过是一个低级错误

List<Object> args = new ArrayList<Object>();
        
        if (condition.getFdate() != null) {
            args.add(condition.getFdate());
        }
        if (condition.getChId() != null) {
            args.add(condition.getChId());
        }
      
        if(condition.getPostTypeCode() != null){
            args.add(condition.getPostTypeCode());
        }
        if (condition.getPlanType() != null) {
            args.add(condition.getPlanType());
        }
        return (List<RecData>) super
                .query(needSql, recData,args);

原因：未将args转化为Object[]，因为args是List<Object>类型而非Objec[]类型，故弹出以下错误：
解决方法：将语句改为return (List<RecData>) super.query(needSql, recData,args.toArray());即可
