空间查询时遇到大的Geometry时，要用Clob做参数的形式进行查询，不然会报字符串太大的异常。

　　//获取list（clob做参数）
    public List findDataByClob(final String str, final String[] clobArgs){
        final StringBuffer sql = new StringBuffer();
        sql.append(str);

                    //throws SQLException {
                PreparedStatement  ps = null;
                try{
                String str = sql.toString();
                ps=con.prepareStatement(str);
                for (int i = 0; i < clobArgs.length; i++) {
                    Clob clob=con.createClob();
                    clob.setString(i+1,new String(clobArgs[i]));
                    ps.setClob(i+1,clob);
                }
                }catch(Exception e){
