你能给我一个简短的解释和一个@PathVariable在春季mvc 使用的样品吗？请详细说明您输入网址的方式？
我正在努力获得正确的网址来显示jsp页面.谢谢.

不推荐使用HibernatePersistence.class.该代码的替代方案应该是什么？

import org.hibernate.ejb.HibernatePersistence
@Bean  
        public LocalContainerEntityManagerFactoryBean entityManagerFactory() {  
                LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();  
                entityManagerFactoryBean.setDataSource(dataSource());  
                entityManagerFactoryBean.setPersistenceProviderClass(HibernatePersistence.class);  
                entityManagerFactoryBean.setPackagesToScan(env.getRequiredProperty(PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN));  

                entityManagerFactoryBean.setJpaProperties(hibProperties());  

                return entityManagerFactoryBean;  
        } 

输出显示$ {message}而不是"Spring".
是否需要依赖来显示我的消息的价值？
我已经使用过Spring MVC,但我使用的是xml配置.我在这里错过了什么吗？希望你能帮助我解决这个问题.
