我已经在 Spring Boot 应用程序中配置了 ACL。 ACL配置如下:
@Configuration
@ComponentScan(basePackages = "com.company")
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true)
public class ACLConfigration extends GlobalMethodSecurityConfiguration {
@Autowired
DataSource dataSource;
@Bean
public EhCacheBasedAclCache aclCache() {
return new EhCacheBasedAclCache(aclEhCacheFactoryBean().getObject(), permissionGrantingStrategy(), aclAuthorizationStrategy());
}
@Bean
public EhCacheFactoryBean aclEhCacheFactoryBean() {
EhCacheFactoryBean ehCacheFactoryBean = new EhCacheFactoryBean();
ehCacheFactoryBean.setCacheManager(aclCacheManager().getObject());
ehCacheFactoryBean.setCacheName("aclCache");
return ehCacheFactoryBean;
}
@Bean
public EhCacheManagerFactoryBean aclCacheManager() {
return new EhCacheManagerFactoryBean();
}
@Bean
public DefaultPermissionGrantingStrategy permissionGrantingStrategy() {
ConsoleAuditLogger consoleAuditLogger = new ConsoleAuditLogger();
return new DefaultPermissionGrantingStrategy(consoleAuditLogger);
}
@Bean
public AclAuthorizationStrategy aclAuthorizationStrategy() {
return new AclAuthorizationStrategyImpl(new SimpleGrantedAuthority("ROLE_ACL_ADMIN"));
}
@Bean
public LookupStrategy lookupStrategy() {
return new BasicLookupStrategy(dataSource, aclCache(), aclAuthorizationStrategy(), new ConsoleAuditLogger());
}
@Bean
public JdbcMutableAclService aclService() {
return new JdbcMutableAclService(dataSource, lookupStrategy(), aclCache());
}
@Bean
public DefaultMethodSecurityExpressionHandler defaultMethodSecurityExpressionHandler() {
return new DefaultMethodSecurityExpressionHandler();
}
@Override
public MethodSecurityExpressionHandler createExpressionHandler() {
DefaultMethodSecurityExpressionHandler expressionHandler = defaultMethodSecurityExpressionHandler();
expressionHandler.setPermissionEvaluator(new AclPermissionEvaluator(aclService()));
expressionHandler.setPermissionCacheOptimizer(new AclPermissionCacheOptimizer(aclService()));
return expressionHandler;
}
}

安全配置如下:
@Configuration
@EnableWebSecurity
public class CustomSecurityConfiguration extends WebSecurityConfigurerAdapter {
@Bean
public AuthenticationEntryPoint entryPoint() {
return new LoginUrlAuthenticationEntryPoint("/authenticate");
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf()
.disable()
.authorizeRequests()
.antMatchers("/authenticate/**").permitAll()
.anyRequest().fullyAuthenticated()
.and().requestCache().requestCache(new NullRequestCache())
.and().addFilterBefore(authenticationFilter(), CustomUsernamePasswordAuthenticationFilter.class);
}
@Override
public void configure(WebSecurity web) throws Exception {
web.ignoring().antMatchers(HttpMethod.OPTIONS, "/**");
}
@Bean
public CustomUsernamePasswordAuthenticationFilter authenticationFilter()
throws Exception {
CustomUsernamePasswordAuthenticationFilter authenticationFilter = new CustomUsernamePasswordAuthenticationFilter();
authenticationFilter.setUsernameParameter("username");
authenticationFilter.setPasswordParameter("password");
authenticationFilter.setFilterProcessesUrl("/authenticate");
authenticationFilter.setAuthenticationSuccessHandler(new CustomAuthenticationSuccessHandler());
authenticationFilter.setAuthenticationFailureHandler(new CustomAuthenticationFailureHandler());
authenticationFilter.setAuthenticationManager(authenticationManagerBean());
return authenticationFilter;
}
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
}
My CustomAuthenticationProvider
class:
@Component
public class CustomAuthenticationProvider implements AuthenticationProvider {
@Autowired
private UsersService usersService;
@Override
public Authentication authenticate(Authentication authentication)
throws AuthenticationException {
String username = authentication.getName();
String password = authentication.getCredentials().toString();
User user = usersService.findOne(username);
if(user != null && usersService.comparePassword(user, password)){
return new UsernamePasswordAuthenticationToken(
user.getUsername(),
user.getPassword(),
AuthorityUtils.commaSeparatedStringToAuthorityList(
user.getUserRoles().stream().collect(Collectors.joining(","))));
} else {
return null;
}
}
@Override
public boolean supports(Class<?> authentication) {
return authentication.equals(UsernamePasswordAuthenticationToken.class);
}
}
这是我的CustomUsernamePasswordAuthenticationToken
:
public class CustomUsernamePasswordAuthenticationFilter extends UsernamePasswordAuthenticationFilter {
@Override
public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response)
throws AuthenticationException {
if(!request.getMethod().equals("POST"))
throw new AuthenticationServiceException(String.format("Authentication method not supported: %s", request.getMethod()));
try {
CustomUsernamePasswordAuthenticationForm form = new ObjectMapper().readValue(request.getReader(), CustomUsernamePasswordAuthenticationForm.class);
String username = form.getUsername();
String password = form.getPassword();
if(username == null)
username = "";
if(password == null)
password = "";
UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(username, password);
setDetails(request, token);
return getAuthenticationManager().authenticate(token);
} catch (IOException exception) {
throw new CustomAuthenticationException(exception);
}
}
private class CustomAuthenticationException extends RuntimeException {
private CustomAuthenticationException(Throwable throwable) {
super(throwable);
}
}
}
除了以上这些,我还有CustomAuthenticationFailureHandler
, CustomAuthenticationSuccessHandler
, CustomNoRedirectStrategy
and CustomUsernamePasswordAuthenticationForm
由于这个问题的长度,我跳过了这个问题。
我正在使用可以找到的 MySQL 架构here http://docs.spring.io/spring-security/site/docs/current/reference/html/appendix-schema.html#persistent-login-remember-me-schema.
我将条目添加到我的 acl 相关表中,如下所示:
INSERT INTO acl_class VALUES (1, com.company.project.domain.users.User)
INSERT INTO acl_sid VALUES (1, 1, "demo")
(我有一个用户名demo
)
INSERT INTO acl_object_identity VALUES (1, 1, 1, NULL, 1, 0)
INSERT INTO acl_entry VALUES (1, 1, 1, 1, 1, 1, 1, 1)
但我得到的只是:
Denying user demo permission 'READ' on object com.company.project.domain.users.User@4a49e9b4
in my
@PostFilter("hasPermission(filterObject, 'READ')")
我在这里怀疑几个问题:
- The
hasPermission
表达式:我已将其替换为“READ”和“1”,但没有任何程度的替换。
- 我的数据库条目不正确
- 我没有实现自定义权限评估器。这是必需的,还是
expressionHandler.setPermissionEvaluator(new AclPermissionEvaluator(aclService()));
enough?
Update
示例方法其中@PostFilter
用来:
@RequestMapping(method = RequestMethod.GET)
@PostFilter("hasPermission(filterObject, 'READ')")
List<User> find(@Min(0) @RequestParam(value = "limit", required = false, defaultValue = "10") Integer limit,
@Min(0) @RequestParam(value = "page", required = false, defaultValue = "0") Integer page,
@RequestParam(value = "email", required = false) String email,
@RequestParam(value = "firstName", required = false) String firstName,
@RequestParam(value = "lastName", required = false) String lastName,
@RequestParam(value = "userRole", required = false) String userRole) {
return usersService.find(
limit,
page,
email,
firstName,
lastName,
userRole);
}
更新#2:
现在的问题反映了有关身份验证/授权/ACL 的所有设置。
更新#3:
我现在非常接近解决这个问题,唯一剩下的就是解决这个问题:
https://stackoverflow.com/questions/42996579/custom-permissionevaluator-not-used-although-set-as-permissionevaluator-deny https://stackoverflow.com/questions/42996579/custom-permissionevaluator-not-called-although-set-as-permissionevaluator-deny
如果有人可以帮助我解决这个问题,我终于可以写下我为解决这个问题所经历的事情。
