在Spring Security中实现分层角色

Question

我试图在Spring安全中实现分层角色，并根据Spring源文档在我的xml文件中添加了以下配置。

<bean id="roleHierarchy" class="org.springframework.security.access.hierarchicalroles.RoleHierarchyImpl"> 
    <property name="hierarchy"> 
     <value> 
      ROLE_ADMIN > ROLE_PRO 
      ROLE_PRO > ROLE_PREMIUM 
      ROLE_PREMIUM > ROLE_BASIC 
      ROLE_BASIC > ROLE_ANONYMOUS 
     </value> 
    </property> 
</bean> 

<bean id="roleVoter" 
     class="org.springframework.security.access.vote.RoleHierarchyVoter"> 
     <constructor-arg ref="roleHierarchy"/> 
</bean> 

我试图与上述各行，但我正在访问被拒而ROLE_ADMIN试图访问分配给ROLE_BASIC的URL。我需要添加比这更多的东西吗？除了Spring站点中的这些行之外，我什么都没发现。另外，如果您知道任何分层角色的良好实施，请务必提及它们。

我想你需要注册roleVoter在accessDecisionManager。 @查看this answer举例。

但说实话，我doubt the Spring Hierarchical Voter concept，因为你需要到处添加一个特殊的阶层选民。我个人比较喜欢其他方式：我实现了一个自定义JdbcDaoImpl，它覆盖了addCustomAuthorities，并将“正常”角色添加到“现有”一次。

/** 
* Extension of {@link JdbcDaoImpl} User Detail Provider, so that is uses the 
* {@link PrivilegesService} to extend the provided Authorities. 
* 
*/ 
public class JdbcDaoPrivilegesImpl extends JdbcDaoImpl { 

    private PrivilegesService privilegesService; 

    public JdbcDaoPrivilegesImpl(final PrivilegesService privilegesService) {   
     this.privilegesService = privilegesService; 
    } 

    @Override 
    protected void addCustomAuthorities(String username, List<GrantedAuthority> authorities) { 
     super.addCustomAuthorities(username, authorities);   

     List<GrantedAuthority> privileges = new ArrayList<GrantedAuthority>(); 
     for (GrantedAuthority role : authorities) { 
      privileges.addAll(privilegesService.getPrivilegesForRole(role)); 
     } 
     authorities.addAll(privileges);  
    } 
} 


public interface PrivilegesService { 

    Collection<? extends GrantedAuthority> getPrivilegesForRole(GrantedAuthority role); 
} 


public class PropertyPrivilegesServiceImpl implements PrivilegesService { 

    /** 
    * Property bases mapping of roles to privileges. 
    * Every role is one line, the privileges are comma separated. 
    */ 
    private Properties roleToPrivileges; 

    public PropertyPrivilegesServiceImpl(Properties roleToPrivileges) { 
     if (roleToPrivileges == null) { 
      throw new IllegalArgumentException("roleToPrivileges must not be null"); 
     } 
     this.roleToPrivileges = roleToPrivileges; 
    } 

    @Override 
    public Collection<? extends GrantedAuthority> getPrivilegesForRole(GrantedAuthority role) { 
     if (roleToPrivileges == null) { 
      throw new IllegalArgumentException("role must not be null"); 
     } 

     String authority = role.getAuthority(); 
     if(authority != null) { 
      String commaSeparatedPrivileges = roleToPrivileges.getProperty(role.getAuthority()); 
      if (commaSeparatedPrivileges != null) { 
       List<GrantedAuthority> privileges = new ArrayList<GrantedAuthority>(); 
       for(String privilegeName : StringUtils.commaDelimitedListToSet(commaSeparatedPrivileges)) { 
        privileges.add(new GrantedAuthorityImpl(privilegeName.trim())); 
       }     
       return privileges; 
      } else { 
       return Collections.emptyList(); 
      } 
     } else { 
      return Collections.emptyList(); 
     } 
    } 
} 

实施例配置

<bean id="myUserDetailsService" class="JdbcDaoForUpdatableUsernames"> 
    <constructor-arg ref="propertyPrivilegesService"/> 
    <property name="dataSource" ref="dataSource"/> 
    <property name="usersByUsernameQuery" value="SELECT login,encryptedPassword,loginEnabled FROM user WHERE login = ?"/> 
    <property name="enableAuthorities" value="true"/> 
    <property name="authoritiesByUsernameQuery" value="SELECT u.login, r.securityRoles FROM user u, user2security_roles r WHERE u.login= ? AND u.id = r. User_fk;"/> 
</bean> 

<bean id="propertyPrivilegesService" class="PropertyPrivilegesServiceImpl"> 
    <constructor-arg> 
     <props> 
      <prop key="ROLE_ADMIN"> 
       ROLE_PREMIUM, 
       ROLE_BASIC 
      </prop> 
      <prop key="ROLE_PREMIUM"> 
       RROLE_BASIC 
      </prop> 
     </props> 
    </constructor-arg> 
</bean> 

Answer 2

尝试通过添加这弹簧的security.xml：

<http auto-config="true" use-expressions="true" access-decision-manager-ref="accessDecisionManager"> 


<beans:bean id="accessDecisionManager" class="org.springframework.security.access.vote.AffirmativeBased"> 
    <beans:constructor-arg> 
     <beans:list> 
      <beans:ref bean="roleVoter" /> 
     </beans:list> 
    </beans:constructor-arg> 
</beans:bean>
