Java配置和Spring Security 3.2的安全方法注释

Question

我在使用由@EnableGlobalMethodSecurityServlet 3.0样式初始化控制的方法级别注释来设置我的应用程序时遇到一些问题

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各自的问题。请注意， 不
使用会@EnableGlobalMethodSecurity导致服务器启动成功，并且所有表单安全性都将按预期执行。我在控制器上添加@EnableGlobalMethodSecurity和@PreAuthorize("hasRole('ROLE_USER')")注释时出现问题。

我试图独立设置基于表单和基于api的安全性。基于方法的注释仅需要用于api安全性。

以下是一种配置。

@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");
        }
    }

}

这不是理想的，因为我真的只希望对身份验证机制进行一次注册，但是主要问题是它导致以下异常：

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，它是自己设置的，AuthenticationManager所以我不确定这是什么问题。

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();
        }
    }

}

该配置实际上成功启动，但有一个例外

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)

当我测试时发现安全性不起作用。

我已经研究了几天，甚至在深入研究Spring Security实现代码后，我似乎也找不到我的配置出了什么问题。

我正在使用spring-security-3.2.0.RC1和spring-framework-3.2.3.RELEASE。

当您使用protected registerAuthentication的方法WebSecurityConfigurerAdapter是范围界定身份验证到WebSecurityConfigurerAdapter如此EnableGlobalMethodSecurity无法找到它。如果您考虑一下……这是有道理的，因为该方法受到保护。

您看到的错误实际上是一个调试语句（请注意级别为DEBUG）。原因是Spring Security将尝试几种不同的方法来自动连接Global Method
Security。具体来说，EnableGlobalMethodSecurity将尝试以下方法来尝试获取AuthenticationManager：

• 如果您扩展GlobalMethodSecurityConfiguration并覆盖，registerAuthentication它将使用AuthenticationManagerBuilder传入的。这允许AuthenticationManager您以与WebSecurityConfigurerAdapter
• 尝试从的全局共享实例进行构建AuthenticationManagerBuilder，如果失败，它将记录您所看到的错误消息（请注意，日志还指出“目前还可以，我们将尝试直接使用AuthenticationManager”）
• 尝试使用AuthenticationManager暴露为Bean的。

对于您的代码，最好使用以下代码：

@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();
        }
    }

}
