获取序列ID时出现的异常，检查oracle数据库表ID字段类型是否为NUMBER类型。如果是long修改为number即可。
有关number类型：http://www.blogjava.net/caojianhua/archive/2011/01/24/343461.html

严重: null

顺便贴出获取序列号的方法：

public static int insertDataReturnKeyByReturnInto() throws Exception {
        Connection conn = GlobalData.getOracleConnection();
        String vsql = "insert into xx(id) values(xx_squencee.nextval) returning id into :1";
        OraclePreparedStatement pstmt = (OraclePreparedStatement) conn.prepareStatement(vsql);
        pstmt.registerReturnParameter(1, Types.BIGINT);
        pstmt.executeUpdate();
        ResultSet rs = pstmt.getReturnResultSet();
        rs.next();
        int id = rs.getInt(1);
        rs.close();
        pstmt.close();
        System.out.print("id:" + id);
        return id;
    }
