使用Java配置和Spring Security 3.2的安全方法注释

Question

我在使用方法级别注释设置我的应用程序时遇到了一些问题,@EnableGlobalMethodSecurity我正在使用Servlet 3.0样式初始化

public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {

    public SecurityWebApplicationInitializer() {
        super(MultiSecurityConfig.class);
    }
}

我尝试了两种不同的方法来初始化AuthenticationManager两者都有自己的问题.请注意,在成功启动服务器时不使用@EnableGlobalMethodSecurity结果,并且所有表单安全性都按预期执行.当我在控制器上添加@EnableGlobalMethodSecurity和@PreAuthorize("hasRole('ROLE_USER')")注释时,我的问题出现了.

我试图独立设置基于表单和基于api的安全性.基于注释的方法仅需要用于api安全性.

一种配置如下.

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled=true)
public class MultiSecurityConfig {

    @Configuration
    @Order(1)
    public static class ApiWebSecurityConfigurationAdapter extends WebSecurityConfigurerAdapter {
        protected void configure(HttpSecurity http) throws Exception {
            http.antMatcher("/api/**").httpBasic();
        }

        protected void registerAuthentication(AuthenticationManagerBuilder auth) throws Exception {
            auth.inMemoryAuthentication()
                .withUser("user").password("password").roles("USER").and()
                .withUser("admin").password("password").roles("USER", "ADMIN");
        }
    }

    @Configuration
    public static class FormWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {
        public void configure(WebSecurity web) throws Exception {
            web.ignoring().antMatchers("/static/**","/status");
        }

        protected void configure(HttpSecurity http) throws Exception {
            http.authorizeRequests().anyRequest().hasRole("USER").and()
                .formLogin().loginPage("/login").permitAll();
        }

        protected void registerAuthentication(AuthenticationManagerBuilder auth) throws Exception {
            auth.inMemoryAuthentication()
                .withUser("user").password("password").roles("USER").and()
                .withUser("admin").password("password").roles("USER", "ADMIN");
        }
    }

}

这并不理想,因为我真的只想要一次注册认证机制,但主要问题是它会导致以下异常:

java.lang.IllegalArgumentException: Expecting to only find a single bean for type interface org.springframework.security.authentication.AuthenticationManager, but found []

据我所知@EnableGlobalMethodSecurity建立自己的AuthenticationManager所以我不确定这里的问题是什么.

第二种配置如下.

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled=true)
public class MultiSecurityConfig {

    @Bean
    protected AuthenticationManager authenticationManager() throws Exception {
        return new AuthenticationManagerBuilder(ObjectPostProcessor.QUIESCENT_POSTPROCESSOR)
                .inMemoryAuthentication()
                    .withUser("user").password("password").roles("USER").and()
                    .withUser("admin").password("password").roles("USER", "ADMIN").and()
                    .and()
                .build();
    }

    @Configuration
    @Order(1)
    public static class ApiWebSecurityConfigurationAdapter extends WebSecurityConfigurerAdapter {
        @Override protected void configure(HttpSecurity http) throws Exception {
            http.antMatcher("/api/**").httpBasic();
        }
    }

    @Configuration
    public static class FormWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {
        public void configure(WebSecurity web) throws Exception {
            web.ignoring().antMatchers("/static/**","/status");
        }

        protected void configure(HttpSecurity http) throws Exception {
            http.authorizeRequests().anyRequest().hasRole("USER").and()
                .formLogin().loginPage("/login").permitAll();
        }
    }

}

此配置实际上已成功启动,但有例外

java.lang.IllegalArgumentException: A parent AuthenticationManager or a list of AuthenticationProviders is required
at org.springframework.security.authentication.ProviderManager.checkState(ProviderManager.java:117)
at org.springframework.security.authentication.ProviderManager.<init>(ProviderManager.java:106)
at org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder.performBuild(AuthenticationManagerBuilder.java:221)

当我测试时,我发现安全性不起作用.

我已经看了几天了,甚至在深入了解Spring安全实现代码后,我似乎无法找到我的配置有什么问题.

我使用的是spring-security-3.2.0.RC1和spring-framework-3.2.3.RELEASE.

当您使用protected registerAuthentication方法上WebSecurityConfigurerAdapter则作用域验证到WebSecurityConfigurerAdapter如此EnableGlobalMethodSecurity无法找到它.如果你考虑这个...它是有道理的,因为该方法是受保护的.

您看到的错误实际上是一个调试语句(注意级别是DEBUG).原因是Spring Security将尝试使用几种不同的方法来自动连接全局方法安全性.具体EnableGlobalMethodSecurity将尝试以下方式尝试获取AuthenticationManager:

• 如果你扩展GlobalMethodSecurityConfiguration和覆盖registerAuthentication它将使用AuthenticationManagerBuilder传入的.这允许隔离,AuthenticationManager就像你可以使用相同的方式隔离WebSecurityConfigurerAdapter
• 尝试从全局共享实例构建AuthenticationManagerBuilder,如果失败则记录您看到的错误消息(注意日志还说明"现在可以,我们将尝试直接使用AuthenticationManager")
• 尝试使用AuthenticationManager暴露为bean的方法.

对于您的代码,您最好使用以下内容:

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled=true)
public class MultiSecurityConfig {
    // Since MultiSecurityConfig does not extend GlobalMethodSecurityConfiguration and
    // define an AuthenticationManager, it will try using the globally defined
    // AuthenticationManagerBuilder to create one

    // The @Enable*Security annotations create a global AuthenticationManagerBuilder 
    // that can optionally be used for creating an AuthenticationManager that is shared
    // The key to using it is to use the @Autowired annotation
    @Autowired
    public void registerSharedAuthentication(AuthenticationManagerBuilder auth) throws Exception {
        auth
            .inMemoryAuthentication()
                .withUser("user").password("password").roles("USER").and()
                .withUser("admin").password("password").roles("USER", "ADMIN");
    }

    @Configuration
    @Order(1)
    public static class ApiWebSecurityConfigurationAdapter extends WebSecurityConfigurerAdapter {
        // Since we didn't specify an AuthenticationManager for this class,
        // the global instance is used


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

    @Configuration
    public static class FormWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {
        // Since we didn't specify an AuthenticationManager for this class,
        // the global instance is used

        public void configure(WebSecurity web) throws Exception {
            web
                .ignoring()
                    .antMatchers("/static/**","/status");
        }

        protected void configure(HttpSecurity http) throws Exception {
            http
                .authorizeRequests()
                    .anyRequest().hasRole("USER")
                    .and()
                .formLogin()
                    .loginPage("/login")
                    .permitAll();
        }
    }

}
