SpringMVC 代理问题 [英] SpringMVC Proxy issue
本文介绍了SpringMVC 代理问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
这几天我一直在努力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，我一直做得很好.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.
I have been trying to find an answer to this problem for days, and I hope someone can point me in the right direction. I have a SpringMVC app that uses Java Configuration and I was doing fine until I tried to integrate Apache-Shiro into it. I am able to build and run my tests. But my deploy fails because of Proxy/CGLIB issues.
这是我在部署/重启时遇到的异常:
Here is the exception I get on deploy/restart:

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.正是添加这一点导致了代理问题.
And here is the other Configuration class. It is the addition of this that causes the proxy issues.
@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:
the offending class is just a 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.
I have added the @EnableTransactionManagement(proxyTargetClass=false) which I thought would address the Proxy issue but apparently isn't.
感谢您花时间阅读所有内容.
Thank you for your time in reading all this.
推荐答案
Caused by: java.lang.IllegalArgumentException: Cannot subclass final class class com.sun.proxy.$Proxy69
此异常表示，由于某些错误配置或应用 AOP 的多种方式，正在生成代理的代理.现在对于 JDK 动态代理，这不是问题，但是对于基于类的代理来说却是问题.因为 cglib 使类成为 final(如堆栈跟踪所示).
This exception indicates that, due to some misconfiguration or multiple ways of applying AOP, a proxy of a proxy is being generated. Now with JDK Dynamic Proxies this isn't a problem however with class based proxies it is. Because cglib makes the classes final (as indicated by the stacktrace).
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.
Your configuration has multiple ways of generation proxies, @EnableTransactionManagement triggers the registration of an AutoProxyCreator already. Next you are adding another one.
这种情况下的解决方案是删除 DefaultAdvisorAutoProxyCreator，因为已经有一个为您注册的实例.这将禁用代理代理.
The solution in this case is to remove the DefaultAdvisorAutoProxyCreator as there is already an instance registered for you. This will disable proxying a proxy.
