表单提交，action 地址问题

jsp 页面如下：

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<html>

<head>

    <title>Login</title>

</head>

<body>

    <form action = "/login" method="post">

        username:<input name = "username" value = "username">

        <br><br>

        password:<input type = "password" name = "password" value = "password">

        <br><br>

        <input type = "submit" vlaue = "submit">

    </form>

</body>

</html>

然后点击提交之后，访问的地址为http://localhost:8080/login

这个地址就没有项目名http://localhost:8080/maventest_war_exploded/list.jsp

将action 前面“/”后去掉后如下：

--%>

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<html>

<head>

    <title>Login</title>

</head>

<body>

    <form action = "login" method="post">

        username:<input name = "username" value = "username">

        <br><br>

        password:<input type = "password" name = "password" value = "password">

        <br><br>

        <input type = "submit" vlaue = "submit">

    </form>

</body>

</html>

点击提交后地址栏为：//localhost:8080/maventest_war_exploded/login

总结

action 中：有斜杠访问的是绝对地址，没有斜杠访问的相对地址
