Spring Логин страницы работает, но моя страница входа не?

Question

Страницы входа в Spring работают, но моя страница входа не работает?

Я строю систему в Spring3 с MySQL.если я использую страницу входа в Spring, все работает отлично, но мне не понравился дизайн, поэтому я создал login.jsp и изменил свой файл context.xml, но не могу отобразить свой login.jsp ??

[CODE]<http auto-config="true" use-expressions="true" >
        <intercept-url pattern="/friends/**" access="hasRole('ROLE_USER')" />

    <form-login login-processing-url="/EPA/j_spring_security_check"
                login-page="/login"
                authentication-failure-url="/login?login_error=t"/>
</http>[/CODE]

Ниже приведена ошибка

Answer 1

Spring security может не найти ваш login.jsp и, следовательно, перейти на страницу входа по умолчанию.

Есть ли у вас отображение где-то, которое преобразует /login в login.jsp в соответствующем месте в вашем веб-приложении?Что-то вроде

!-- View Resolver for JSPs -->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

Answer 2

Значение атрибута страницы входа не является именем представления.

Вам нужно сделать 2 вещи:
1. Сопоставить значение атрибута страницы входа в систему с контроллером. Пример:

XML:

<form-login login-page="/mylogin.do" ...  />

Контроллер:

    @RequestMapping("/mylogin.do")
public String showLoginForm() { 
/* return a view name that will be used by your Viewresolver 
   if you return "login" then view resolver will resolve it to login.jsp
*/
... 
}  

2. Предоставить доступ к странице входа:

<intercept-url patter="/mylogin.do" access="permitAll" />  

Answer 3

Ваш логин имеет login-processing-url="/EPA/j_spring_security_check, но поступает запрос на /j_spring_security_check без /EPA.
