java怎样将一个List传入Oracle存储过程。样例例如以下：

数据库端建一个PL/SQL的数组。

CREATE OR REPLACE TYPE tables_array AS VARRAY(100) OF VARCHAR2(32) ;drop table test purge;create table test(  name varchar2(32));create or replace procedure t_list_to_p(arr_t in tables_array) isbegin  for i in arr_t.first .. arr_t.last loop    insert  into test values(arr_t(i));  end loop;  commit;end t_list_to_p;

java代码：

import java.sql.CallableStatement;import java.sql.Connection;import java.sql.DriverManager;import java.sql.SQLException;import java.util.ArrayList;import java.util.List;import oracle.sql.ARRAY;import oracle.sql.ArrayDescriptor;public class TestListToProcedure {    static final String driver_class  = "oracle.jdbc.driver.OracleDriver";    static final String connectionURL = "jdbc:oracle:thin:@10.150.15.150:1521:orcl";    static final String userID        = "test";    static final String userPassword  = "test";    public void runTest() {        Connection  con = null;        CallableStatement stmt = null ;        try {            Class.forName (driver_class).newInstance();            con = DriverManager.getConnection(connectionURL, userID, userPassword);            stmt = con.prepareCall("{call t_list_to_p(?

)}"); ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor("TABLES_ARRAY",con); List list = new ArrayList(); list.add("张三"); list.add("李四"); list.add("王五"); ARRAY array = new ARRAY(descriptor,con,list.toArray()); stmt.setArray(1, array); stmt.execute(); } catch (SQLException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); }finally{ if(stmt != null){ try { stmt.close(); } catch (SQLException e) { e.printStackTrace(); } } if(con != null){ try { con.close(); } catch (SQLException e) { e.printStackTrace(); } } } } public static void main(String[] args) { TestListToProcedure testListToProcedure = new TestListToProcedure(); testListToProcedure.runTest(); } }
