Spring 安全 ACL，@Secured 注解答案

【问题描述】：

我目前遇到了spring security问题，我一直在关注最后两个参考on the spring security article page的教程

使用org.springframework.security.access.annotation.Secured 保护的方法似乎不会触发任何 Spring Security 逻辑。

这是我的测试文件：

 public class AclServiceTest {

 @Autowired
 PersonDataOnDemand pdod;

 @Autowired
 MyAclService aclService;

 UserDetailsService uds = new MyUserDetailsService();

 @Test
 public void testWriteResourceAnnotation(){
  Person p0 = pdod.getSpecificPerson(0);
  Person p1 = pdod.getSpecificPerson(1);

  Assert.isTrue(!p0.getId().equals(p1.getId()));

  Resource r = new Resource(p0.getSite(), p0, p0.getPrivateFolder());

  authenticatePerson(p0);
  securedWriteResource(r);

  authenticatePerson(p1);
  try{
   securedWriteResource(r);
   fail();
  } catch(Exception e){

  }
 }


 @Secured("ACL_RESOURCE_WRITE")
 public void securedWriteResource(Resource r){
  return;  
 }

 private void authenticatePerson(Person p){
  UserDetails ud = uds.loadUserByUsername(p.getEmail());
  SecurityContextHolder.getContext().setAuthentication(new RunAsUserToken("user-"+p.getId(), ud, p.getPassword(), ud.getAuthorities().toArray(new GrantedAuthority[0]), null));
 }
}

如果将以下行添加到我的web.xml

<!--Spring security filter-->
<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>

这是我使用的 bean 的 security.xml 配置：

<?xml version="1.0" encoding="UTF-8"?>

businessAccessDecisionManager bean 被创建并被赋予投票者，但决不调用该方法。

有人知道出了什么问题吗？

感谢您的帮助。

标签： annotations spring-security acl

【解决方案1】：

我发现<global-method-security ../> 没有插入到正确的 xml 文件中。有关详细信息，请参阅here。这个文件恰好是我 Roo 项目中的 webmvc-config.xml。

这引发了几个问题，我需要 ACL 的 SpEL，所以我最终确定了这个配置：

<bean class="org.springframework.security.access.expression.method.DefaultMethodSecurityExpressionHandler" id="methodExprHandler">
    <property name="permissionEvaluator" ref="aclPermissionEvaluator" />
</bean>
<bean class="org.springframework.security.acls.AclPermissionEvaluator" id="aclPermissionEvaluator">
    <constructor-arg ref="jdbcMutableAclService" />
</bean>


<security:global-method-security pre-post-annotations="enabled">
    <security:expression-handler ref="methodExprHandler"/>
</security:global-method-security>

没有投票者授权逻辑。
