《MysqL必读jdbc调用MysqL存储过程实现代码》要点：
本文介绍了MysqL必读jdbc调用MysqL存储过程实现代码，希望对您有用。如果有疑问，可以联系我们。
建立一个MysqL的存储过程 add_pro
代码如下:
delimiter //
drop procedure add_pro //
create procedure add_pro(a int,b int,out sum int )
begin
set sum = a * b;
end;
//
2. 调用存储过程
代码如下:
package com.zhanggaosong;
import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.Types;
public class CallableStatementTest {
public static final String DRIVER_CLASS = "com.MysqL.jdbc.Driver";
public static final String URL = "jdbc:MysqL://127.0.0.1:3306/test";
public static final String USERNAME = "root";
public static final String PASSWORD = "123456";
public static void main(String[] args) throws Exception {
Class.forName(DRIVER_CLASS);
Connection connection = DriverManager.getConnection(URL,USERNAME,
PASSWORD);
String sql = "{CALL add_pro(?,?,?)}"; //调用存储过程
CallableStatement cstm = connection.prepareCall(sql); //实例化对象cstm
cstm.setInt(1,122);
cstm.setInt(2,2); //
cstm.registerOutParameter(3,Types.INTEGER); // 设置返回值类型
cstm.execute(); // 执行存储过程
System.out.println(cstm.getInt(3));
cstm.close();
connection.close();
}
}
