如何在自定义过滤器中使用 Java 配置注入 AuthenticationManager

我使用的是 Spring Security 3.2和 Spring 4.0.1

我正在将 xml 配置转换为 Java 配置。当我在过滤器中用 @Autowired注释 AuthenticationManager时，我得到了一个异常

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.security.authentication.AuthenticationManager] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}

我已经尝试过注入 AuthenticationManagerFactoryBean，但是由于类似的异常也失败了。

下面是我正在使用的 XML 配置

<?xml version="1.0" encoding="UTF-8"?> <beans ...>
<security:authentication-manager id="authenticationManager">
<security:authentication-provider user-service-ref="userDao">
<security:password-encoder ref="passwordEncoder"/>
</security:authentication-provider>
</security:authentication-manager>


<security:http
realm="Protected API"
use-expressions="true"
auto-config="false"
create-session="stateless"
entry-point-ref="unauthorizedEntryPoint"
authentication-manager-ref="authenticationManager">
<security:access-denied-handler ref="accessDeniedHandler"/>
<security:custom-filter ref="tokenAuthenticationProcessingFilter" position="FORM_LOGIN_FILTER"/>
<security:custom-filter ref="tokenFilter" position="REMEMBER_ME_FILTER"/>
<security:intercept-url method="GET" pattern="/rest/news/**" access="hasRole('user')"/>
<security:intercept-url method="PUT" pattern="/rest/news/**" access="hasRole('admin')"/>
<security:intercept-url method="POST" pattern="/rest/news/**" access="hasRole('admin')"/>
<security:intercept-url method="DELETE" pattern="/rest/news/**" access="hasRole('admin')"/>
</security:http>


<bean class="com.unsubcentral.security.TokenAuthenticationProcessingFilter"
id="tokenAuthenticationProcessingFilter">
<constructor-arg value="/rest/user/authenticate"/>
<property name="authenticationManager" ref="authenticationManager"/>
<property name="authenticationSuccessHandler" ref="authenticationSuccessHandler"/>
<property name="authenticationFailureHandler" ref="authenticationFailureHandler"/>
</bean>


</beans>

这是我正在尝试的 Java 配置

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {


@Autowired
private UserDetailsService userDetailsService;


@Autowired
private PasswordEncoder passwordEncoder;


@Autowired
private AuthenticationEntryPoint authenticationEntryPoint;


@Autowired
private AccessDeniedHandler accessDeniedHandler;


@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth
.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder);
}


@Override
protected void configure(HttpSecurity http) throws Exception {
http
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and()
.exceptionHandling()
.authenticationEntryPoint(authenticationEntryPoint)
.accessDeniedHandler(accessDeniedHandler)
.and();
//TODO: Custom Filters
}
}

这是自定义过滤器类。给我带来麻烦的那行是 AuthenticationManager 的 setter

@Component
public class TokenAuthenticationProcessingFilter extends AbstractAuthenticationProcessingFilter {




@Autowired
public TokenAuthenticationProcessingFilter(@Value("/rest/useAuthenticationManagerr/authenticate") String defaultFilterProcessesUrl) {
super(defaultFilterProcessesUrl);
}




@Override
public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException, IOException, ServletException {
...
}


private String obtainPassword(HttpServletRequest request) {
return request.getParameter("password");
}


private String obtainUsername(HttpServletRequest request) {
return request.getParameter("username");
}


@Autowired
@Override
public void setAuthenticationManager(AuthenticationManager authenticationManager) {
super.setAuthenticationManager(authenticationManager);
}


@Autowired
@Override
public void setAuthenticationSuccessHandler(AuthenticationSuccessHandler successHandler) {
super.setAuthenticationSuccessHandler(successHandler);
}


@Autowired
@Override
public void setAuthenticationFailureHandler(AuthenticationFailureHandler failureHandler) {
super.setAuthenticationFailureHandler(failureHandler);
}
}

最佳答案

Override method authenticationManagerBean in WebSecurityConfigurerAdapter to expose the AuthenticationManager built using configure(AuthenticationManagerBuilder) as a Spring bean:

For example:

   @Bean(name = BeanIds.AUTHENTICATION_MANAGER)
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}

In addition to what Angular University said above you may want to use @Import to aggregate @Configuration classes to the other class (AuthenticationController in my case) :

@Import(SecurityConfig.class)
@RestController
public class AuthenticationController {
@Autowired
private AuthenticationManager authenticationManager;
//some logic
}

When I @Bean'ed AuthenticationManager and @Autowired it in same class then needed to activate circular references but that is rather as for CDI.
