各位专家，

我目前正在学习 Spring Boot，我想将它与 Spring Security ACL 一起使用。按照Spring Security的文档和Baeldung.com上的教程，我想我对需要什么有所了解。我还研究了Spring 的 DMS 示例。我通过寻找解决方案偶然发现了另一个例子。

基于这些信息，我构建了我的应用程序。作为参考，您可以在GitHub 上找到当前应用程序。

当前问题

当我启动应用程序时，我被java.lang.IllegalStateException: No ServletContext set抛出了。据我了解，这是因为在 Spring Boot 的自动配置魔术期间，我的@Configuration注释类在初始化之前ServletContext被初始化。

链接到pastebin上的完整堆栈跟踪。

到目前为止我做了什么

根据我的研究（主要是在 StackOverflow 上）和我目前对该问题的理解，将负责Bean的 s 放入自己的带@Configuration注释的类中应该会有所帮助。不幸的是，我现在迷路了。相关问题使我产生了这种想法（请参阅此问题或此问题。）

我的环境

  • macOS 10.12.6
  • jdk1.8.0_144
  • IntelliJ IDEA 2017.3.3（终极版）
  • Spring Boot v1.5.9.RELEASE

大家好，

我设法自己解决了这个问题。我一步一步地评论/取消评论所有MethodSecurity相关的东西。

我将其归结为DefaultMethodSecurityExpressionHandler. 这导致了IllegalStateException: No ServletContext set.

然后，我创建了一个新类MethodSecurityConfig.java，并将所有相关代码放在那里。现在应用程序再次启动，我可以继续开发。

@Rakesh ：感谢您的意见！

MethodSecurityConfig.java

@Configuration
public class MethodSecurityConfig {

    private DataSource dataSource;

    @Autowired
    @Qualifier("traderDiaryDataSource")
    public void setDataSource(DataSource dataSource) {
        this.dataSource = dataSource;
    }

    @Bean
    public MethodSecurityExpressionHandler aclExpressionHandler() {
        DefaultMethodSecurityExpressionHandler expressionHandler =
            new DefaultMethodSecurityExpressionHandler();

        AclPermissionCacheOptimizer permissionCacheOptimizer =
            new AclPermissionCacheOptimizer(aclService());

            expressionHandler.setPermissionEvaluator(permissionEvaluator());
            expressionHandler
                .setPermissionCacheOptimizer(permissionCacheOptimizer);
        return expressionHandler;
    }

    @Bean
    public PermissionEvaluator permissionEvaluator() {
        return new AclPermissionEvaluator(aclService());
    }

    @Bean
    public JdbcMutableAclService aclService() {
        return new JdbcMutableAclService(dataSource,
            lookupStrategy(), aclCache());
    }

    @Bean
    public LookupStrategy lookupStrategy() {
        return new BasicLookupStrategy(dataSource, aclCache(),
            aclAuthorizationStrategy(), new ConsoleAuditLogger());
    }

    @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 PermissionGrantingStrategy permissionGrantingStrategy() {
        return new DefaultPermissionGrantingStrategy(
            new ConsoleAuditLogger());
    }

    @Bean
    public AclAuthorizationStrategy aclAuthorizationStrategy() {
        return new AclAuthorizationStrategyImpl(
            new SimpleGrantedAuthority("ROLE_ADMIN"));
    }
}

WebSecurityConfig.java

@Configuration
@EnableGlobalMethodSecurity(securedEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    ...

    @Configuration
    protected static class AclMethodSecurityConfig
        extends GlobalMethodSecurityConfiguration {

        private MethodSecurityExpressionHandler aclExpressionHandler;

        @Autowired
        @Qualifier("aclExpressionHandler")
        public void setAclExpressionHandler(
            MethodSecurityExpressionHandler aclExpressionHandler) {

            this.aclExpressionHandler = aclExpressionHandler;
        }

        @Override
        protected MethodSecurityExpressionHandler createExpressionHandler() {
            return aclExpressionHandler;
        }
    }
}

只是为了跟进您自己的答案和我之前的评论，我也迷失了这个答案（超过 2 天！）。最后，它还覆盖了GlobalMethodSecurityConfiguration子类中的configure(AuthenticationManagerBuilder auth)方法，该子类也用@EnableGlobalMethodSecurity注释。

由于我是 Spring 新手，不幸的是，我无法提供有关为什么会这样的详细信息，但是如果我将AuthenticationManagerBuilder的配置放在扩展WebSecurityConfigurereAdapter的类中（就像我最初拥有的那样），那么我总是会得到一个IllegalStateException: No ServletContext set错误。

这是我使用的最终代码：

@Configuration
@EnableGlobalMethodSecurity( prePostEnabled = true, securedEnabled = true )
public class MethodSecurityConfig extends GlobalMethodSecurityConfiguration {


@Override
protected MethodSecurityExpressionHandler createExpressionHandler() {
    return defaultMethodSecurityExpressionHandler();

}

@Override
protected void configure( final AuthenticationManagerBuilder authenticationManagerBuilder ) throws Exception {
    authenticationManagerBuilder.authenticationProvider( authenticationProvider() );
}


@Bean
public JdbcDaoImpl jdbcDao() {

    JdbcDaoImpl jdbcDao = new JdbcDaoImpl();
    jdbcDao.setDataSource( dataSource() );

    return jdbcDao;
}


@Bean
public DaoAuthenticationProvider authenticationProvider() {

    final DaoAuthenticationProvider authenticationProvider = new DaoAuthenticationProvider();
    authenticationProvider.setUserDetailsService( jdbcDao() );
    authenticationProvider.setPasswordEncoder( encoder() );

    return authenticationProvider;
}

@Bean
public PasswordEncoder encoder() {
    return new BCryptPasswordEncoder( 11 );
}


@Bean( name = "myDS")
public DataSource dataSource() {

    BasicDataSource dataSource = new BasicDataSource();
    dataSource.setDriverClassName( "com.mysql.cj.jdbc.Driver" );
    dataSource.setUrl( "jdbc:mysql://localhost:3306/java_spring_angular_rest_security_acl2" );
    dataSource.setUsername( "root" );
    dataSource.setPassword( "alphax" );

    return 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 LookupStrategy lookupStrategy() {
    return new BasicLookupStrategy(dataSource(), aclCache(), aclAuthorizationStrategy(), permissionGrantingStrategy());
}

@Bean
public AclAuthorizationStrategy aclAuthorizationStrategy() {
    return new AclAuthorizationStrategyImpl(new SimpleGrantedAuthority("ROLE_ADMIN"));
}


@Bean
public PermissionGrantingStrategy permissionGrantingStrategy() {
    return new DefaultPermissionGrantingStrategy(new ConsoleAuditLogger());
}


@Bean( name = "defaultMethodSecurityExpressionHandler")
public MethodSecurityExpressionHandler defaultMethodSecurityExpressionHandler() {

    DefaultMethodSecurityExpressionHandler expressionHandler = new DefaultMethodSecurityExpressionHandler();
    AclPermissionEvaluator permissionEvaluator = new AclPermissionEvaluator(aclService());

    expressionHandler.setPermissionEvaluator(permissionEvaluator);
    expressionHandler.setPermissionCacheOptimizer( new AclPermissionCacheOptimizer( aclService() ) );

    return expressionHandler;
}

@Bean( name = "myAclService")
public JdbcMutableAclService aclService() {

    JdbcMutableAclService jdbcMutableAclService =  new JdbcMutableAclService(dataSource(), lookupStrategy(), aclCache());
    jdbcMutableAclService.setClassIdentityQuery( "SELECT @@IDENTITY" );
    jdbcMutableAclService.setSidIdentityQuery( "SELECT @@IDENTITY" );

    return jdbcMutableAclService;
}

}
