java如何将一个List传入Oracle存储过程，例子如下：

**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) is
    begin
      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();
        }
    
    }
