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

  1 import java.sql.CallableStatement;
  2 import java.sql.Connection;
  3 import java.sql.DriverManager;
  4 import java.sql.SQLException;
  5 import java.util.ArrayList;
  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;
 11 
 12 public class TestListToProcedure {
 13     static final String driver_class  = "oracle.jdbc.driver.OracleDriver";
 14     static final String connectionURL = "jdbc:oracle:thin:@10.150.15.150:1521:orcl";
 15     static final String userID        = "test";
 16     static final String userPassword  = "test";
 17     public void runTest() {
 18         Connection  con = null;
 19         CallableStatement stmt = null ;
 20         try {
 21             Class.forName (driver_class).newInstance();
 22             con = DriverManager.getConnection(connectionURL, userID, userPassword);
 23             StructDescriptor tDescriptor = StructDescriptor.createDescriptor("TEST_OBJECT", con);
 24         	List<STRUCT> structs = new ArrayList<STRUCT>();
 25         	Object[] 	tObject  = null ;
 26         	//能够将系统中VO,DTO转化成Object对象,先创建struts
 27         	for(int i = 0; i<10; i++){
 28         		tObject = new Object[2];
 29         		tObject[0] = i;
 30         		tObject[1] = "name"+i;
 31                 STRUCT tStruct = new STRUCT(tDescriptor, con, tObject);
 32                 structs.add(tStruct);
 33         	}
 34         	ArrayDescriptor arrayDescriptor = ArrayDescriptor.createDescriptor("TABLES_ARRAY", con);
 35         	ARRAY tArray = new ARRAY(arrayDescriptor, con, structs.toArray());
 36             stmt = con.prepareCall("{call t_list_to_p(?
 37 )}");  
 38             stmt.setArray(1, tArray);
 39             stmt.execute();
 40         }  catch (SQLException e) {
 41             e.printStackTrace();
 42         } catch (Exception e) {
 43             e.printStackTrace();
 44         }finally{
 45         	if(stmt != null){
 46         		try {
 47 					stmt.close();
 48 				} catch (SQLException e) {
 49 					e.printStackTrace();
 50 				}
 51         	}
 52         	if(con != null){
 53         		try {
 54         			con.close();
 55 				} catch (SQLException e) {
 56 					e.printStackTrace();
 57 				}
 58         	}
 59         }
 60     }
 61     public static void main(String[] args) {
 62     	TestListToProcedure testListToProcedure = new TestListToProcedure();
 63     	testListToProcedure.runTest();
 64     }
