使用JDBC调用存储过程

public int insertStu(String sname,String ssex) throws Exception {
    Connection con = Dbhelper.getconnection();
    PreparedStatement ps = null;
    int result = -1;
    if(con!=null) {
        try {
            String sql = "insert into t_student values("+sname+","+ssex+")";
            ps = con.prepareStatement(sql);
            ps.executeUpdate();
            con.close();
        } 
        catch(Exception ex) {
            System.out.println(ex);
        } 
        finally{
            try {
                ps.close();
            } catch(Exception ex1) {
                System.out.println(ex1);
            }
        }
    }
    return result;
}

public int insertStu(String sname,String ssex) throws Exception {
    Connection con = Dbhelper.getconnection();
    PreparedStatement ps = null;
    int result = -1;
    if(con!=null) {
        try {
            //String sql = "exec indata(‘"+sname+"‘,‘"+ssex+"‘)";     //这样是不行的
            String sql = "{call indata(‘"+sname+"‘,‘"+ssex+"‘)}";     //应该写成这样
            System.out.println(sql);
            ps = con.prepareCall(sql);
            ps.executeUpdate();
            con.close();
        } catch(Exception ex) {
            System.out.println(ex);
        } finally{
            try {
                ps.close();
            } catch(Exception ex1) {
                System.out.println(ex1);
            }
        }
    }
    return result;
