java 调用存储过程 传入和返回全部是自定义数组

String result="";Connection con = DriverManager.getConnection("jdbc:oracle:thin:@192.168.19.133:1521:gbk10g", "wzh", "wzh");long start = System.currentTimeMillis();con.setAutoCommit(false);CallableStatement cstmt = con.prepareCall("{ ? = call getRowMd5(?) }");//设置返回的数组类型cstmt.registerOutParameter(1,OracleTypes.ARRAY,"TABLE_DM");//开始设置传入数组List<String> list=new ArrayList<String>(); for(int i=1;i<=1000;i++){list.add(i+"");}ArrayDescriptor arrayDesc = ArrayDescriptor.createDescriptor("EMPARRAY", con); ARRAY array = new ARRAY(arrayDesc, con, list.toArray());cstmt.setArray(2, array);//结束设置传入数组cstmt.execute();con.commit();//开始处理传入数组Array aa = cstmt.getArray(1);Object[] obj = (Object[]) aa.getArray(); for (int i = 0; i < obj.length; i++) { STRUCT struct = (STRUCT) obj[i]; Datum[] dt = struct.getOracleAttributes(); for (int n = 0; n < dt.length; n++) { System.out.print(dt[n]+" "); } System.out.println(); }//结束处理传入数组cstmt.close();con.close();long end = System.currentTimeMillis();System.out.println(end-start);return result;
