这里的问题是，您正在为Servlet和根上下文使用相同的配置。这就是为什么您有两个配置实例。在Spring
MVC中，您有2个上下文，即servlet上下文和根上下文。servlet上下文用于控制器，而根上下文用于业务对象和服务。
如果您不想使用XML，请创建两个配置类。像这样的东西：
根上下文 ：
@Configuration@EnableTransactionManagement@ComponentScan("pl.mbrnwsk.sklep")public class AppConfiguration { public String hbm2ddl_auto = "update"; public AppConfiguration(){ System.out.println("AppConfiguration"); } @Bean public DataSource dataSource() { DriverManagerDataSource ds = new DriverManagerDataSource(); ds.setDriverClassName("org.hsqldb.jdbcDriver"); ds.setUrl("jdbc:hsqldb:file:/SklepDB/"); ds.setUsername("SA"); ds.setPassword(""); return ds; } @Bean public SessionFactory sessionFactory() { LocalSessionFactoryBuilder ss = new LocalSessionFactoryBuilder(dataSource()); ss.scanPackages("pl.mbrnwsk.sklep.model"); ss.setProperty("hibernate.show_sql", "true"); ss.setProperty("hibernate.hbm2ddl.auto", hbm2ddl_auto); ss.setProperty("hibernate.dialect", "org.hibernate.dialect.HSQLDialect"); return ss.buildSessionFactory(); } @Bean public PlatformTransactionManager txManager(){ return new HibernateTransactionManager(sessionFactory()); }}Servlet上下文 ：
@Configuration@ComponentScan("pl.mbrnwsk.sklep.controller")public class ServletConfiguration { public AppConfiguration(){ System.out.println("ServletConfiguration"); } @Bean public ViewResolver viewResolver(){ InternalResourceViewResolver viewResolver = new InternalResourceViewResolver(); viewResolver.setPrefix("/"); viewResolver.setSuffix(".jsp"); return viewResolver; }}Web.xml ：
