<beans:beans xmlns="http://www.springframework.org/schema/security"

        <!-- 开启表单登录功能 -->

        <form-login/>

    </http>

    <!-- 认证管理器 -->

    <authentication-manager>

        <authentication-provider>

            <user-service>

                <user name="admin" password="123456" authorities="ROLE_USER"/>

                <user name="ztp" password="ztp" authorities="ROLE_ADMIN"/>

            </user-service>

        </authentication-provider>

    </authentication-manager>

</beans:beans>

任意index.html文件：略

启动

此处的登录时springSecurity内置。

自定义登录页面：

编写login.html

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

    <table>

        <tr>

            <td>用户名：</td>

            <td><input type="text" id="username" name="username">

        </tr>

        <tr>

            <td>密码：</td>

            <td><input type="password" id="password" name="password">

        </tr>

        <tr>

            <td colspan="2"><input type="submit" value="登录">

        </tr>

    </table>

</form>

修改spring-security.xml文件

<!-- 新规则  设置该页面不登录也能使用-->

    <http pattern="/login.html" security="none"/>

    <http pattern="/error.html" security="none"/>

    <!-- 页面拦截规则 -->

    <http use-expressions="false">

        <intercept-url pattern="/**" access="ROLE_ADMIN" />

        <!-- 开启表单登录功能  需要排除掉 /index.html-->

        <form-login login-page="/login.html" default-target-url="/index.html" authentication-failure-url="/login_error.html"/>

    </http>

    <!-- 认证管理器 -->

    <authentication-manager>

        <authentication-provider>

            <user-service>

                <user name="admin" password="123456" authorities="ROLE_USER"/>

                <user name="ztp" password="ztp" authorities="ROLE_ADMIN"/>

            </user-service>

        </authentication-provider>

    </authentication-manager>
