一、创建oracle 需要保存的数据类型type和存储过程produce


create TYPE "AL01TYPE"                                                                                                                                                                                                                                  as object

        ARRAY array=null;
        C3P0NativeJdbcExtractor cp30NativeJdbcExtractor = new C3P0NativeJdbcExtractor();

        if (objlist != null && objlist.size() > 0) {
            StructDescriptor structdesc = new StructDescriptor(OracleObj, connection);
            STRUCT[] structs = new STRUCT[objlist.size()];
            for (int i = 0; i < objlist.size(); i++) {

    }
}


 List<Object[]> arrList = new ArrayList<>();

        }
//开始调用过程
        long startTime=System.currentTimeMillis();
        Connection connection = null;

        try {
            connection = dataSource.getConnection();
            ARRAY paramArr = OracleUtil.getArray(connection,"AL01TYPE","AL01TYPELIST",arrList);
            sqlres = connection.prepareCall(sql);
            sqlres.setArray(1, paramArr);
            sqlres.registerOutParameter(2, Types.VARCHAR);
            sqlres.execute();
            msg = sqlres.getString(2);
            long endTime=System.currentTimeMillis()-startTime;
            System.out.println("上传后获取的返回参数为："+msg+"||耗时："+endTime/1000+"秒");
        } catch (SQLException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }finally {
            try {
