java怎样将一组对象传入Oracle存储过程

Posted 2020-09-12 brucemengbm

 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

样例例如以下：

CREATE OR REPLACE TYPE TEST_OBJECT AS OBJECT 
(
  id number,
  name varchar2(32)
);
CREATE OR REPLACE TYPE TABLES_ARRAY AS VARRAY(100) OF TEST_OBJECT;
drop table test purge;
create table test
(
  id number,
  name varchar2(32)
);
create or replace procedure t_list_to_p(arr_t in tables_array) 
is
begin
  for i in 1..arr_t.count loop
      insert  into test values(arr_t(i).id,arr_t(i).name);
  end loop;
  commit;
end t_list_to_p;

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 userPassword  = "test";
    public void runTest() {
        Connection  con = null;
        CallableStatement stmt = null ;
        try {
            Class.forName (driver_class).newInstance();
            con = DriverManager.getConnection(connectionURL, userID, userPassword);
            StructDescriptor tDescriptor = StructDescriptor.createDescriptor("TEST_OBJECT", con);
        	List<STRUCT> structs = new ArrayList<STRUCT>();
        	Object[] 	tObject  = null ;
        	//能够将系统中VO，DTO转化成Object对象,先创建struts
        	for(int i = 0; i<10; i++){
        		tObject = new Object[2];
        		tObject[0] = i;
        		tObject[1] = "name"+i;
                STRUCT tStruct = new STRUCT(tDescriptor, con, tObject);
                structs.add(tStruct);   		
        	}
        	ArrayDescriptor arrayDescriptor = ArrayDescriptor.createDescriptor("TABLES_ARRAY", con);
        	ARRAY tArray = new ARRAY(arrayDescriptor, con, structs.toArray());
            stmt = con.prepareCall("{call t_list_to_p(?
)}");  
            stmt.setArray(1, tArray);
            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) {

				}
        	}
        }
    }
    public static void main(String[] args) {
    	TestListToProcedure testListToProcedure = new TestListToProcedure();
    	testListToProcedure.runTest();
    }
