调用存储过程

Java调用存储过程一直存在着神秘感，他可以替你完成很多你不能完成的任务，这不，我们来瞧瞧吧

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Types;

public class ProcedureTest {

	public static void main(String[] args) {
		testProcedureByOne();
		testProcedureByList();
	}

	public static Connection getConnection() {
		Connection con = null;
		try {
			Class.forName("oracle.jdbc.driver.OracleDriver");
			String url = "jdbc:oracle:thin:@192.168.17.145:1521:erp";
			String userName = "erp";
			String password = "erpdev";
			con = DriverManager.getConnection(url, userName, password);
		} catch (ClassNotFoundException e) {
			e.printStackTrace();
		} catch (SQLException e) {
			e.printStackTrace();
		}

		return con;
	}

	public static void closeConnection(Connection con, CallableStatement ps,
			ResultSet rs) {
		try {
			if (con != null) {
				con.close();
			}
			if (ps != null) {
				ps.close();
			}
			if (rs != null) {
				rs.close();
			}

		} catch (SQLException e) {
			e.printStackTrace();
		}
	}

	public static void testProcedureByOne() {
		Connection con = getConnection();
		CallableStatement proc = null;
		ResultSet rs = null;
		try {
			proc = con.prepareCall("{ call zxw_testdb(?,?)}");
			proc.setString(1, "bbb");
			proc.registerOutParameter(2, Types.VARCHAR);
			proc.execute();
			String testPrint = proc.getString(2);
			System.out.println("test:" + testPrint);
		} catch (SQLException e) {
			e.printStackTrace();
		} finally {
			closeConnection(con, proc, rs);
		}
	}

	public static void testProcedureByList() {
		Connection con = getConnection();
		CallableStatement proc = null;
		ResultSet rs = null;
		try {
			proc = con.prepareCall("{ call zxw.testc(?) }");
			proc.registerOutParameter(1, oracle.jdbc.OracleTypes.CURSOR);
			proc.execute();
			rs = (ResultSet) proc.getObject(1);
			while (rs.next()) {
				System.out.println("<tr><td>" + rs.getString(1) + "</td><td>"
						+ rs.getString(2) + "</td></tr>");
			}
		} catch (SQLException e) {

		} finally {

		}
	}
