spring-security java config:如何配置多个AuthenticationManager实例

Question

我用:

• 弹簧靴:1.1.7
• spring-security:4.0.0.M2
• spring-fmk:4.1.1.RELEASE

一切都配置了Java Config(包括spring-security)

我正在开发一个Web服务器项目,其中Authentication:Basic base64Gibberish header用于验证用户身份.

问题是取决于URI AuthenticationManager是不同的(因为我需要2个不同的UserDetailsService.

• / URI1/**=> authManager1
• / URI2/**=> authManager2

我试过的多个扩展名WebSecurityConfigurerAdapter与

@Override
@Bean( name = "authManager1" )
public AuthenticationManager authenticationManagerBean() throws Exception

@Override
@Bean( name = "authManager2" )
public AuthenticationManager authenticationManagerBean() throws Exception

无济于事

我总是得到:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'springSecurityFilterChain' 
defined in class path resource [org/springframework/security/config/annotation/web/configuration/WebSecurityConfiguration.class]: Instantiation of bean failed; 
nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: 
Factory method [public javax.servlet.Filter org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration.springSecurityFilterChain() throws java.lang.Exception] 
threw exception; nested exception is java.lang.IllegalArgumentException: 
Expecting to only find a single bean for type interface org.springframework.security.authentication.AuthenticationManager, 
but found [authManager1, authManager2]

由于我有多个安全过滤器链,如何"告诉"spring-security在不同的安全过滤器链中注入不同的AuthenticationManager？

在此先感谢P.

您可以拥有多个http配置元素,每个元素都有自己的元素AuthenticationManager.它可能看起来像这样:

@Configuration
@EnableWebSecurity
public class SecurityConfig {

    @Bean
    private AuthenticationManager authenticationManager1() {
        // defines first AuthenticationManager
        return authenticationManager;
    }

    @Bean
    private AuthenticationManager authenticationManager2() {
        // defines second AuthenticationManager
        return authenticationManager;
    }

    @Configuration
    @Order(1)
    public static class Uri1ApiConfigurationAdapter extends WebSecurityConfigurerAdapter {

        @Autowired
        @Qualifier(authenticationManager1)
        private authManager1;

        @Override
        protected AuthenticationManager authenticationManager() {
            return authManager1;
        }

        protected void configure(HttpSecurity http) throws Exception {
            http
                .antMatcher("/URI1/**")
                ...
        }
    }

    @Configuration
    @Order(2)
    public static class Uri2ApiConfigurationAdapter extends WebSecurityConfigurerAdapter {

        @Autowired
        @Qualifier(authenticationManager2)
        private authManager2;

        @Override
        protected AuthenticationManager authenticationManager() {
            return authManager2;
        }

        protected void configure(HttpSecurity http) throws Exception {
            http
                .antMatcher("/URI2/**")
                ...
        }
    }
}
