There are four requirements for a custom login page in Spring Security:

There is an input field named j_username which will contain the name used for the authentication credentials.
There is an input field named j_password which will contain the password used for the authentication credentials.
The url to which these values are POSTed matches the url defined in the login-processing-url attribute of the form-login element in your Spring Security configuration.
The location of the custom login form must be specified in the login-page attribute of the form-login element in your Spring Security configuration.

Login.html

    <body>
      <form action="/j_spring_security_check" method="POST">
        <label for="username">User Name:</label>
        <input id="username" name="j_username" type="text"/>
        <label for="password">Password:</label>
        <input id="password" name="j_password" type="password"/>
        <input type="submit" value="Log In"/>
      </form>
    </body>

Spring Security Configuration File

    <http use-expressions="true">
      <intercept-url pattern="/login*" access="isAnonymous()"/>
      <intercept-url pattern="/**" access="isFullyAuthenticated()"/>
      <form-login
        login-page="/login.html"
        login-processing-url="/j_spring_security_check.action"
        authentication-failure-url="/login_error.html"
        default-target-url="/home.html"
        always-use-default-target="true"/>
    </http>

被撕碎了的回忆

I have been working for a couple of days on implementing spring security in my project and the configuration that finally did it was the following:

spring-security.xml

<security:http auto-config="true" disable-url-rewriting="true" use-expressions="true">

    <security:form-login 
        login-page="/login.html"
        login-processing-url="/j_spring_security_check.action"
        default-target-url="/index.html"
        always-use-default-target="true"
        authentication-failure-url="/login.html?error=true" />
    <security:intercept-url pattern="/login*" access="isAnonymous()" />
    <security:intercept-url pattern="/**" access="hasRole('ROLE_USER')" />
</security:http>

<security:authentication-manager>
    <security:authentication-provider>
        <security:jdbc-user-service
            data-source-ref="dataSource"
            users-by-username-query="select username, password, enabled from smartcaldb.users where username=?"
            authorities-by-username-query="select u.username, r.authority from smartcaldb.users u, smartcaldb.roles r where u.userid = r.userid and u.username =?" />
    </security:authentication-provider>
</security:authentication-manager>

spring-config.xml

<mvc:annotation-driven />
<context:component-scan base-package="com.smartcal.**" />

<!-- setup database connectivity bean -->

<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource"
    destroy-method="close">
    <property name="driverClassName" value="${jdbc.driverClassName}" />
    <property name="url" value="${jdbc.url}" />
    <property name="username" value="${jdbc.username}" />
    <property name="password" value="${jdbc.password}" />
</bean>

<context:property-placeholder location="/WEB-INF/jdbc.properties" />

<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">

        <input id="password" name="j_password" type="password" />
        <input type="submit" value="Log In" />
    </form>
</body>

for logout use url - "/{yourAppPathInTheContainer}/j_spring_security_logout"
