java – Spring Security – 无法注销

我是Spring Framework的初学者.我和我的朋友正在波兹南理工大学写我们的工程师论文,我们遇到了Spring Security(3.1.0)的问题.我不能很好地退出.当我想再次登录时,我看到消息“用户已经登录”(我覆盖了标准的Spring Security错误消息).我试图清除SecurityContextHolder的上下文但它仍然无法正常工作.

弹簧security.xml文件

    </security:authentication-manager>


    <bean id="myAuthenticationProvider" name="myAuthenticationProvider" class="org.pp.web.Authentication.XtbAuthenticationProvider"/>
</beans>`

web.xml中

<!-- Spring Security -->
    <filter>
        <filter-name>springSecurityFilterChain</filter-name>
        <filter-class>
                  org.springframework.web.filter.DelegatingFilterProxy
        </filter-class>
    </filter>



    <filter-mapping>
        <filter-name>springSecurityFilterChain</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

针对home.jsp

<a href="<c:url value="/logout" />">Logout</a>

Controller.java

@RequestMapping(value = "logout")
public String logout() {
    SecurityContextHolder.clearContext();
    return "redirect:/j_spring_security_logout";
}

@RequestMapping(value = "start")
public String start(Model model, HttpServletRequest request) {
    // sprawdzenie czy uzytkownik nie jest juz zalogowany
    if (request.getRemoteUser() == null) {

        return "start";
    } else {

        return "redirect:/home";
    }
}

我有自己的提供商来检查登录名和密码.

AuthProvider.java

public class AuthenticationProvider implements AuthenticationProvider{

private Logger logger = Logger.getLogger(AuthenticationProvider.class);

@Override
public Authentication authenticate(Authentication authentication)
        throws AuthenticationException {

    List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
    authorities.add(new GrantedAuthorityImpl("ROLE_USER"));

    UsernamePasswordAuthenticationToken auth = (UsernamePasswordAuthenticationToken) authentication;
    String username = String.valueOf(auth.getPrincipal());
    String password = String.valueOf(auth.getCredentials());

    if(username.length()<4)
    {
        logger.warn("Error: Login is to short for username: "+ username);
        throw new BadCredentialsException("Login is to short!");
    }
    else if(password.length()<4)
    {
        logger.warn("Error: Password is to short for username: "+ username);
        throw new BadCredentialsException("Password is to short!");

    }
    else if(!(  (username.equals("login") & password.equals("password"))|
            (username.equals("login2") & password.equals("password2"))) ) {
        logger.warn("Error: Incorrect data for username: "+ username);
        throw new BadCredentialsException("Incorrect data!");
    }

    return new UsernamePasswordAuthenticationToken(
        authentication.getName(), authentication.getCredentials(),
        authorities);
}

@Override
public boolean supports(Class<?> authentication) {
    return authentication.equals(UsernamePasswordAuthenticationToken.class);
}

}

我试图解决它,我看起来很长时间,但我找不到解决方案.

我希望你帮助我.

编辑:
我重写了标准的Spring Security错误消息.

更改后的代码.

Controller.java

    @RequestMapping(value = "dummy")
public String dummy() {
    //SecurityContextHolder.clearContext();
    return "redirect:/dummy";
}


@RequestMapping(value = "logout")
public String logout() {
    //SecurityContextHolder.clearContext();
    return "redirect:/start";
}

dummy.jsp

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<html>

<% 

session.invalidate(); 
// String redirectURL = "http://localhost:8080/start";
// response.sendRedirect(redirectURL);

%>

<body>
<%-- <c:redirect url='http://localhost:8080/start' /> --%>
</body>

</html>

针对home.jsp

<a href="<c:url value='/dummy' />">Logout</a>
最佳答案
在JSP重定向中但在设置中没有问题.

试试这个:

添加到web.xml

<listener> 
<listener-class>
org.springframework.security.web.session.HttpSessionEventPublisher
</listener-class> 
</listener>
