Spring的基于Java的配置不适用于我

我是Spring编程的新手,目前正在为Spring 3.1的Java Based Configuraion挣扎.

@Configuration
@ImportResource("classpath:/resources/jdbc.properties")
public class AppConfig {

    @Autowired
    Environment env;
    private @Value("${jdbc.url}")
    String url;
    private @Value("${jdbc.username}")
    String username;
    private @Value("${jdbc.password}")
    String password;

    @Bean
    public DataSource dataSource() {
        System.out.println("Creating data Source.");
        return new DriverManagerDataSource(url,username,password);
    }

    @Bean
    public SessionFactory sessionFactory () throws Exception {
        return new AnnotationSessionFactoryBuilder().setDataSource(dataSource()).setPackagesToScan("com.argusoft.loginmodule.domain").buildSessionFactory();
    }
}

现在,当我尝试运行项目时,出现以下错误.

输出值

SEVERE: Exception while loading the app :
java.lang.IllegalStateException: ContainerBase.addChild: start:
org.apache.catalina.LifecycleException:
java.lang.IllegalArgumentException: javax.servlet.ServletException:
java.lang.NoClassDefFoundError:
org/springframework/core/env/EnvironmentCapable

陷入其中,无法解决它…..我在关注Spring Source Blog.

还请提出一些好的教程,其中通过易于理解的示例来说明Spring最新的基于Java的配置…

提前致谢,
