mysql 存储过程调用 mybatis/hibernate

创建mysql存储过程：

1 CREATE PROCEDURE `findEmpById`(IN id INTEGER(11),OUT count INT)
2 begin
3      select COUNT(*) INTO count from emp where empId=id;
4 end;

//in   输入

//out 输出

//into 昵称

19     public static void main(String[] args) throws SQLException {
20         Configuration cfg = new Configuration().configure();
21         SessionFactory factory = cfg.buildSessionFactory();
22         Session session = factory.openSession();
23         Connection con = session.connection();
24         String sql = "{call findEmpById(?)}";
25         CallableStatement cs = con.prepareCall(sql);
26         cs.setObject(1, 2);
27         ResultSet rs = cs.executeQuery();
28         while(rs.next()){
29             int id = rs.getInt("empId");
30             String name = rs.getString("empName");
31             System.out.println(id+"\t"+name);
32         }
