  1. POSpringMVC Proxy issue
    text
    copied!<p>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. </p> <p>Here is the exception I get on deploy/restart: </p> <pre><code> Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'menuRepository': Post-processing of the FactoryBean's object failed;

&lt;/dependency&gt; ... &lt;/&gt; </code></pre> <p>I use this web config:</p> <pre><code>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 );

dispatcher.addMapping( "/" ); servletContext.addFilter( "shiroFilter", new DelegatingFilterProxy( "shiroFilter", dispatcherContext ) ) .addMappingForUrlPatterns( null, false, "/*" ); } } </code></pre> <p>Here is my primary Configuration class:</p> <pre><code>@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;

creator.setProxyTargetClass(true); return creator; } } </code></pre> <p>And here is the other Configuration class. It is the addition of this that causes the proxy issues.</p> <pre><code>@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; } } </code></pre> <p>the offending class is just a spring jparepository:</p> <pre><code>public interface MenuRepository extends CrudRepository&lt;Menu, Long&gt;, JpaSpecificationExecutor&lt;Menu&gt; { ...} </code></pre> <p>I have added the <strong><em>@EnableTransactionManagement(proxyTargetClass=false)</em></strong> which I thought would address the Proxy issue but apparently isn't. </p> <p>Thank you for your time in reading all this. </p>
