我试图让某人将匹配结果输入到 html 页面中，然后该数据将输入到数据库中，但我无法插入任何数据，我错过了什么？
这是我的代码：
输入结果.html
<html>
<head>
<title>Result</title>
</head>
<body>
<FORM METHOD=GET ACTION="MatchResult.java">
Enter your home team:
<INPUT TYPE="text" NAME="newhomet" VALUE = "" >
Enter your away team:
<INPUT TYPE="text" NAME="newawayt" VALUE = "" >
Enter your home score:
<INPUT TYPE="text" NAME="newhomes" VALUE = "" >
Enter your away score:
<INPUT TYPE="text" NAME="newaways" VALUE = "" >
<INPUT TYPE="submit" VALUE = "Submit">
</FORM>
</body>
</html>
匹配结果.jsp

statement.executeUpdate(insertion);
System.out.println("\nContents after insertion:\n");
}
catch(SQLException sqlEx)
{
System.out.println("* Cannot execute insertion! *");
sqlEx.printStackTrace();
System.exit(1);
}
disconnectFromDb();
