Question

我无法找到Spring安全集成中的问题。我已经用了2-3天了。所以，请帮助我。

下面的

是我的web.xml文件

以下是我的applicationContext.xml文件

     <import resource="classapth*:spring/SpringSecurityConfig.xml" />
<!--      <bean name="springSecurityFilterChain" class="org.springframework.web.filter.OncePerRequestFilter"/> -->
</beans>

下面是我的SpringSecurityConfig.xml

http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.1.xsd“＆GT;

我有以下问题。

是否有必要在web.xml中提供“filter”标签，如果是，为什么？
在我的应用程序中，我有两个应用程序上下文（一个用于spring安全性，另一个用于dispatcher-servlet），springSecurityConfig.xml是否可以访问在dispatcher-servlet.xml中定义的bean定义？
spring-security配置的流程是什么。据我所知，我已经理解 intercept-url 标签拦截请求并使用表达式语言检查适当的角色。我无法理解它通过我提供的身份验证管理器在DB中看起来是合适的角色。

下面是我在service.xml中的userService bean定义

    <bean name="userService" class="com.qait.cdl.services.impl.UserServiceImpl">
            <property name="userDao" ref="userDao" />
        </bean>

下面是userService接口

public interface UserService extends UserDetailsService{
}

此UserDetailsService来自springframework

下面是UserServiceimpl类

public class UserServiceImpl implements UserService {
 public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException, DataAccessException {
        UserDetails userDetails = null;
        if(username != null &&  !"".equals(username)){
            User user = userDao.get(username);
            if(user != null){
                UserGroupAuthority groupAuthority = userDao.getUserAuthority(user);
                if(groupAuthority != null){
                    Collection<GrantedAuthority> grantedAuthorities = getGrantedAuthorities(groupAuthority.getAuthority());
                    userDetails = new org.springframework.security.core.userdetails.User(user.getUsername(), user.getPassword(), 
                            true, true, true, true, grantedAuthorities);
                }
            }
        }
        return userDetails;
    }

    @Override
    public Collection<GrantedAuthority> getGrantedAuthorities(String authority) {
        List<GrantedAuthority> grantedAuthorities = new LinkedList<GrantedAuthority>();
        grantedAuthorities.add(new GrantedAuthorityImpl("ROLE_USER"));
        return grantedAuthorities;
    }

    @Override
    public UserGroupAuthority getUserAuthority(User user) {
        return userDao.getUserAuthority(user);
    }
}

问题是，它没有验证给定的拦截网址。我在哪里做错了？

Answer 1

在springSecurityFilterChain中激活web.xml。这是Spring Security的切入点。如果springSecurityFilterChain被取消激活，那么Spring Security永远不会工作。

无法将Spring安全性集成到现有应用程序中
