【问题描述】：

我这几天一直在寻找这个问题的答案，我希望有人能指出我正确的方向。我有一个使用 Java 配置的 SpringMVC 应用程序，在我尝试将 Apache-Shiro 集成到其中之前我做得很好。我能够构建和运行我的测试。但是由于代理/CGLIB 问题，我的部署失败了。

这是我在部署/重启时遇到的异常：

我使用这个网络配置：

public class EdmWebInitializer implements WebApplicationInitializer {

    private static final String DISPATCHER_SERVLET_NAME = "dispatcher";
    private static final String DISPATCHER_SERVLET_MAPPING = "/*";

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {

        // Create the 'root' Spring application context
        AnnotationConfigWebApplicationContext rootContext = new 
AnnotationConfigWebApplicationContext();

       //I have two @Configuration classes:
       rootContext.register( EdmConfiguration.class, SecurityConfig.class );

        // Manage the lifecycle of the root application context
        servletContext.addListener( new ContextLoaderListener( rootContext ) );


        // Create the dispatcher servlet's Spring application context
        AnnotationConfigWebApplicationContext dispatcherContext = new AnnotationConfigWebApplicationContext();
        dispatcherContext.setServletContext( servletContext );
        dispatcherContext.setParent( rootContext );

        // it seems I have to register the Configuration classes again or I can't @Autowire
         dispatcherContext.register( EdmConfiguration.class, SecurityConfig.class );



        // Register and map the dispatcher servlet
        ServletRegistration.Dynamic dispatcher = servletContext.addServlet( "dispatcher", new DispatcherServlet( dispatcherContext ) );
        dispatcher.setLoadOnStartup( 1 );
        dispatcher.addMapping( "/" );


        servletContext.addFilter( "shiroFilter", new DelegatingFilterProxy( "shiroFilter", dispatcherContext ) )
                .addMappingForUrlPatterns( null, false, "/*" );
    }  
}

这是我的主要配置类：

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = { "com.company.product.service", "com.company.product.utility",
        "com.company.product.controller", "com.company.product.utility.startup",
        "com.company.product.security", "com.company.product.repository.people" })
@EnableTransactionManagement(proxyTargetClass=false)
@ImportResource({ "classpath:applicationContext.xml" })
@PropertySource({ "classpath:application.properties", "classpath:mail.properties" })
public class EdmConfiguration extends WebMvcConfigurationSupport {

    @Resource
    private Environment environment;

    @Autowired
    private org.apache.shiro.web.mgt.WebSecurityManager securityManager;

    @Bean
    public DataSource dataSource() {
        BoneCPDataSource dataSource = new BoneCPDataSource();

        dataSource.setDriverClass( environment.getRequiredProperty( PROPERTY_NAME_DATABASE_DRIVER ) );
        dataSource.setJdbcUrl( environment.getRequiredProperty( PROPERTY_NAME_DATABASE_URL ) );
        dataSource.setUsername( environment.getRequiredProperty( PROPERTY_NAME_DATABASE_USERNAME ) );
        dataSource.setPassword( environment.getRequiredProperty( PROPERTY_NAME_DATABASE_PASSWORD ) );

        return dataSource;
    }

    @Bean
    public JpaTransactionManager transactionManager() throws ClassNotFoundException {
        JpaTransactionManager transactionManager = new JpaTransactionManager();

        transactionManager.setEntityManagerFactory( entityManagerFactoryBean().getObject() );

        return transactionManager;
    }

    @Bean
    public DelegatingFilterProxy springSecurityFilterChain() {
        return new DelegatingFilterProxy();
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean() throws ClassNotFoundException {
        LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();

        entityManagerFactoryBean.setDataSource( dataSource() );
        entityManagerFactoryBean.setPackagesToScan( environment
                .getRequiredProperty( PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN ) );
        entityManagerFactoryBean.setPersistenceProviderClass( HibernatePersistence.class );

        Properties jpaProperties = new Properties();

        ...

        entityManagerFactoryBean.setJpaProperties( jpaProperties );

        return entityManagerFactoryBean;
    }

    @Bean
    public PersistenceExceptionTranslator exTranslator() {
        return new HibernateExceptionTranslator();
    }

    @Bean(initMethod = "init")
    public StartupListener startupListener() {
        return new StartupListener();
    }

    @Bean
    public StandardPasswordEncoder encoder() {
        return new org.springframework.security.crypto.password.StandardPasswordEncoder();
    }


    @Bean
    public ShiroFilterFactoryBean shiroFilter() {
        ShiroFilterFactoryBean shiroFilter = new org.apache.shiro.spring.web.ShiroFilterFactoryBean();
        shiroFilter.setSecurityManager( securityManager);
        shiroFilter.setLoginUrl( "/login" );
        shiroFilter.setUnauthorizedUrl( "/" );
        return shiroFilter;
    }



    @Bean
    @DependsOn(value = "lifecycleBeanPostProcessor")
    public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
        DefaultAdvisorAutoProxyCreator creator = new DefaultAdvisorAutoProxyCreator();
        creator.setProxyTargetClass(true);
        return creator;
    }
}

这是另一个配置类。正是添加这个会导致代理问题。

@Configuration
public class SecurityConfig {

    @Bean
    public SaltAwareJdbcRealm saltAwareJdbcRealm() {
        return new SaltAwareJdbcRealm();
    }

    @Bean
    public WebSecurityManager securityManager() {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm( saltAwareJdbcRealm() );
        return securityManager;
    }

    @Bean
    public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {
        return new LifecycleBeanPostProcessor();
    }

    @Bean
    public MethodInvokingFactoryBean methodInvokingFactoryBean() {
        MethodInvokingFactoryBean methodInvokingFactoryBean = new MethodInvokingFactoryBean();
        methodInvokingFactoryBean.setStaticMethod( "org.apache.shiro.SecurityUtils.setSecurityManager" );
        methodInvokingFactoryBean.setArguments( new Object[]{ securityManager() } );
        return methodInvokingFactoryBean;
    }

    @Bean
    @DependsOn(value = "lifecycleBeanPostProcessor")
    public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor() {
        AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
        authori

zationAttributeSourceAdvisor.setSecurityManager( securityManager() );
            return authorizationAttributeSourceAdvisor;
        }       
    }

违规类只是一个spring jparepository：

public interface MenuRepository extends CrudRepository<Menu, Long>, JpaSpecificationExecutor<Menu> {

...}

我添加了 @EnableTransactionManagement(proxyTargetClass=false)，我认为它可以解决代理问题，但显然不是。

感谢您花时间阅读所有内容。

【问题讨论】：

请澄清，因为目前还不清楚问题是什么。你基本上说，它不起作用，转储大量代码并期望这里的人修复它。
对不起，我会尽量澄清我原来的帖子。
由于某种原因触发了为代理创建代理。从您的代码来看，您正在混合不同的代理策略，为什么需要额外的DefaultAdvisorAutoProxyCreator？
@M. Deinum - 老实说，我不知道为什么我两者都有。我已经看到一些文档说我需要 DefaultAdvisorAutoProxyCreator 和一些我需要 proxyTargetClass=false）。并且更改它们似乎没有影响。
您应该可以删除DefaultAdvisorAutoProxyCreator。如前所述，问题在于您现在有多种生成代理的方法（应用 AOP），这通常会导致代理使用 cglib 代理（基于类的代理）无法实现的代理。

标签： spring spring-mvc spring-data shiro

【解决方案1】：

Caused by: java.lang.IllegalArgumentException: Cannot subclass final class class com.sun.proxy.$Proxy69

此异常表明，由于某些错误配置或多种应用 AOP 的方式，正在生成代理的代理。现在使用 JDK 动态代理，这不是问题，但是基于类的代理却是这样。因为 cglib 使类成为最终类（如堆栈跟踪所示）。

您的配置有多种生成代理的方式，@EnableTransactionManagement 已经触发了AutoProxyCreator 的注册。接下来，您将添加另一个。

这种情况下的解决方案是删除DefaultAdvisorAutoProxyCreator，因为已经为您注册了一个实例。这将禁用代理代理。
