java怎样将一组对象传入Oracle存储过程

java怎样将一组对象传入Oracle存储过程。须要注意的是jar包是有要求的，假设使用不当会导致仅仅有数字能传过去，字符串传只是去。

假设是Oracle11g则须要选用例如以下的jar包，F:\app\Administrator\product\11.2.0\dbhome_1\jlib\orai18n.jar、D:\program\weblogic\oracle_common\modules\oracle.jdbc_11.2.0\ojdbc6.jar

1：存储过程

  1 CREATE OR REPLACE TYPE TEST_OBJECT AS OBJECT
  2 (
  3   id number,
  4   name varchar2(32)
  5 );
  6 CREATE OR REPLACE TYPE TABLES_ARRAY AS VARRAY(100) OF TEST_OBJECT;
  7 drop table test purge;
  8 create table test
  9 (
 10   id number,
 11   name varchar2(32)
 12 );
 13 create or replace procedure t_list_to_p(arr_t in tables_array)
 14 is
 15 begin
 16   for i in 1..arr_t.count loop
 17       insert  into test values(arr_t(i).id,arr_t(i).name);
 18   end loop;
 19   commit;
 20 end t_list_to_p;

2:Java 实现逻辑代码

  6 import java.util.List;
  7 import oracle.sql.ARRAY;
  8 import oracle.sql.ArrayDescriptor;
  9 import oracle.sql.STRUCT;
 10 import oracle.sql.StructDescriptor;
