【问题描述】:
我正在尝试将我的 Spring 应用程序配置为拥有一个非常基本的带有 Spring 安全性的安全系统。 我希望在没有安全过滤器的情况下提供资源,过滤标准页面以检查用户是否具有“用户”角色,并提供 /admin/ 页面以检查角色是否为“管理员”。
我拥有的是:
springSecurityFilterChain org.springframework.web.filter.DelegatingFilterProxy
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
在web.xml中,而spring-security.xml是:
<security:http security="none" pattern="/resources/**"/>
<security:http auto-config="true" use-expressions="true" >
<security:intercept-url pattern="/admin/**" access="hasRole('Admin')" />
<security:logout logout-success-url="/welcome" logout-url="/logout" />
<security:form-login login-page="/FormLogin"
default-target-url="/welcome"
username-parameter="username"
password-parameter="hashPwd"
authentication-failure-url="/login?error"
/>
</security:http>
<security:authentication-manager>
<security:authentication-provider user-service-ref="controlloUtente">
<security:password-encoder hash="bcrypt" />
</security:authentication-provider>
</security:authentication-manager>
<beans:bean id="controlloUtente"
class="org.fabrizio.fantacalcio.utility.SpringSecurityServiceImpl">
</beans:bean>
然后我配置了这个类:
package org.fabrizio.fantacalcio.utility;
import java.util.ArrayList;
import java.util.Collection;
import java.util.List;
import org.fabrizio.fantacalcio.model.beans.Utente;
import org.fabrizio.fantacalcio.model.dao.UtenteDaoImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
@Service
@Transactional
public class SpringSecurityServiceImpl implements UserDetailsService{
@Autowired
private UtenteDaoImpl utenteDao;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
Utente utente = utenteDao.getUtenteByUsername(username);
if(utente == null){
throw new UsernameNotFoundException("L'utente inserito non è stato trovato");
}
return convertUtente(utente);
}
private UserDetails convertUtente(Utente utente) {
UserDetails ud = new User(utente.getUsername(), utente.getHashPwd(), true, true, true, true, getRoles(utente));
return ud;
}
private Collection<? extends GrantedAuthority> getRoles(Utente utente) {
GrantedAuthority auth = new SimpleGrantedAuthority(utente.getRuolo().getNome());
List<GrantedAuthority> listaAuth = new ArrayList<GrantedAuthority>();
listaAuth.add(auth);
return listaAuth;
}
}
还有以下一个:
package org.fabrizio.fantacalcio.utility;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.BeanPostProcessor;
import org.springframework.core.PriorityOrdered;
import org.springframework.security.access.annotation.Jsr250MethodSecurityMetadataSource;
import org.springframework.security.access.expression.method.DefaultMethodSecurityExpressionHandler;
import org.springframework.stereotype.Component;
@Component
public class DefaultRolesPrefixPostProcessor implements BeanPostProcessor, PriorityOrdered {
@Override
public Object postProcessAfterInitialization(Object bean, String beanName)
throws BeansException {
if(bean instanceof Jsr250MethodSecurityMetadataSource) {
((Jsr250MethodSecurityMetadataSource) bean).setDefaultRolePrefix("");
}
if(bean instanceof DefaultMethodSecurityExpressionHandler) {
((DefaultMethodSecurityExpressionHandler) bean).setDefaultRolePrefix("");
}
// if(bean instanceof DefaultWebSecurityExpressionHandler) {
// ((DefaultWebSecurityExpressionHandler) bean).setDefaultRolePrefix("");
// }
return bean;
}
@Override
public Object postProcessBeforeInitialization(Object bean, String beanName)
throws BeansException {
return bean;
}
@Override
public int getOrder() {
return PriorityOrdered.HIGHEST_PRECEDENCE;
}
}
但是没有任何效果。 我的 formLogin 不使用弹簧表单,而是使用经典表单。
当我登录并尝试获取像 /admin/testpage 这样的 pge 时,即使我具有管理员角色,我也会被重定向到 FormLogin 页面,这是调试输出:
22/06/2015 10:03:04 - DEBUG - (AntPathRequestMatcher.java:141) - Request '/admin/formregistrazione' matched by universal pattern '/**'
22/06/2015 10:03:04 - DEBUG - (HttpSessionRequestCache.java:43) - DefaultSavedRequest added to Session: DefaultSavedRequest[http://localhost:8080/Fantacalcio/admin/FormRegistrazione]
22/06/2015 10:03:04 - DEBUG - (ExceptionTranslationFilter.java:202) - Calling Authentication entry point.
22/06/2015 10:03:04 - DEBUG - (DefaultRedirectStrategy.java:39) - Redirecting to 'http://localhost:8080/Fantacalcio/FormLogin'
22/06/2015 10:03:04 - DEBUG - (HttpSessionSecurityContextRepository.java:337) - SecurityContext is empty or contents are anonymous - context will not be stored in HttpSession.
有时,登录后,我会收到以下消息:
HTTP Status 403 - Invalid CSRF Token 'null' was found on the request parameter '_csrf' or header 'X-CSRF-TOKEN'.
我做错了什么?我总是必须使用令牌?为什么流程永远不会进入 SpringSecurityServiceImpl 类?
谢谢
编辑:我禁用了csrf,现在情况越来越清楚了。问题在于我的SpringSecurityServiceImpl Autowired utenteDao 实例为空。我像这样编辑了 spring-security.xml 文件,希望 Spring 理解 @Service 注释类但它不起作用:
<security:authentication-manager>
<security:authentication-provider user-service-ref="SpringSecurityServiceImpl">
<security:password-encoder hash="bcrypt" />
</security:authentication-provider>
</security:authentication-manager>
我的 UtenteDao 课程
package org.fabrizio.fantacalcio.model.dao;
import java.util.List;
import org.fabrizio.fantacalcio.model.beans.Utente;
import org.hibernate.criterion.Restrictions;
import org.springframework.stereotype.Repository;
@Repository
public class UtenteDaoImpl extends BaseDaoImpl<Utente> implements UtenteDao{
public UtenteDaoImpl() {
System.out.println("test");
}
@SuppressWarnings("unchecked")
public List<Utente> trovaUtentiAttivi(){
return getSession().createCriteria(Utente.class).add(Restrictions.eq("attivo", true)).list();
}
@SuppressWarnings("unchecked")
public Utente getUtenteFromCredenziali(Utente utente){
List<Utente> utenteTrovato = getSession().createCriteria(Utente.class)
.add(Restrictions.eq("username", utente.getUsername()))
.add(Restrictions.eq("hashPwd", utente.getHashPwd()))
.list();
Utente utenteLoggato = utenteTrovato.size() == 0 ? null : utenteTrovato.get(0);
return utenteLoggato;
}
public Boolean usernameExists(String username){
return getSession().createCriteria(Utente.class)
.add(Restrictions.eq("username", username))
.list().size() > 0;
}
@SuppressWarnings("unchecked")
public Utente getUtenteByUsername(String username){
List<Utente> utenteTrovato = getSession().createCriteria(Utente.class)
.add(Restrictions.eq("username", username))
.list();
Utente utenteLoggato = utenteTrovato.size() == 0 ? null : utenteTrovato.get(0);
return utenteLoggato;
}
}
【问题讨论】:
-
为什么我在你的 securityApplicationContext.xml 中看不到任何 CSRF 配置?
-
我问,我应该强制使用 csrf 令牌吗?
-
其实没有,我看不到你在哪里配置 CSRF,所以你不应该得到那个错误。但是因为你有这个错误,你已经启用了 CSRF,尽管默认情况下它是启用的。
-
或者在你的atConfiguration文件中,你可以把.csrf().disable();用于配置方法。
-
在 Spring Security 4 中默认启用 csrf 保护,在早期版本中它是可选的 (jira.spring.io/browse/SEC-2347)。所以是的,你需要在所有表单中使用它,或者禁用 CSRF 保护。
