JDBC如何調(diào)用存儲(chǔ)過程

啥也不說，直接上代碼了!

1. package cn.itcast.zx;

2.

3. import java.sql.CallableStatement;

4.

5. import java.sql.Connection;

30.

31. try {

32.

33. //這里最好不要這么干，因?yàn)轵?qū)動(dòng)名寫死在程序中了

34.

35. Class.forName("com.mysql.jdbc.Driver");

36.

37. //實(shí)際項(xiàng)目中，這里應(yīng)用DataSource數(shù)據(jù)，如果用框架，

38.

39. //這個(gè)數(shù)據(jù)源不需要我們編碼創(chuàng)建，我們只需Datasource ds = context.lookup()

40.

41. //cn = ds.getConnection();

42.

43. cn = DriverManager.getConnection("jdbc:mysql:///test","root","root");

44.

45. cstmt = cn.prepareCall("{call insert_Student(?,?,?)}");

52.

53. cstmt.execute();

54.

55. //get第幾個(gè)，不同的數(shù)據(jù)庫不一樣，建議不寫

56.

57. System.out.println(cstmt.getString(3));

58.
