Spring4.2+Hibernate5配置

本次配置使用的是注解的方式配置：

1.引入maven依赖

     Spring:

<!--Spring  -->

项目初始化
1.创建WebApp容器，这里使用的是注解容器

public class WebAppContext {
   public static final AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();

   public static <T> T getBean(Class<T> requiredType) {
      return context.getBean(requiredType);
   }

}
2.创建注解容器的配置项
@Configuration
@ComponentScan(basePackages = {"cn"})
@EnableWebMvc
@ImportResource("classpath:conf/dispatch-mvc.xml")
@EnableTransactionManagement(proxyTargetClass = true)
public class WebAppConfig extends WebMvcConfigurerAdapter {
3.创建WebApplicationInitializer的实现类，WebInitializer，实现onStartup方法
@Override
public void onStartup(ServletContext servletContext)
      throws ServletException {
      System.setProperty("APP_CONTEXT_PATH", servletContext.getContextPath());

   /*
    * 创建并注册{@link DispatcherServlet}
    */
WebAppContext.context.register(WebAppConfig.class);

   DispatcherServlet dispatcherServlet = new DispatcherServlet(
         WebAppContext.context);
   dispatcherServlet.setThrowExceptionIfNoHandlerFound(true);

   ServletRegistration.Dynamic dispatcher = servletContext.addServlet(
         AbstractDispatcherServletInitializer.DEFAULT_SERVLET_NAME,
         dispatcherServlet);
   // dispatcher.setInitParameter("throwExceptionIfNoHandlerFound",
   // "true");
dispatcher.setLoadOnStartup(1);
   dispatcher.addMapping(DISPATCHER_SERVLET_MAPPING);

   // /:~
   /*
    * 解决使用Restful时，静态资源被拦截的问题。在Spring3.2中，使用了addResourceHandler方法，    * 对静态资源进行了映射 ，代替此解决方案 。    */
   // servletContext.getServletRegistration("default").addMapping(
   // DEFAULT_URL_MAPPING);
   // /:~
   // Manage the lifecycle of the root application context
servletContext
         .addListener(new ContextLoaderListener(WebAppContext.context));
         // 加入监听器，在系统关闭的时候，注销JDBC Driver
         // servletContext.addListener(new
         // ServletContextScopeListener());
   // add filter
CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
   characterEncodingFilter.setEncoding("UTF-8");
   characterEncodingFilter.setForceEncoding(true);

   servletContext
         .addFilter("CharacterEncodingFilter", characterEncodingFilter)
         .addMappingForUrlPatterns(EnumSet.noneOf(DispatcherType.class),
               false, "/*");
 
   logger.info("Webapp has been initialized at {}",
         DateFormatUtils.format(new Date(), "yyyy-MM-dd HH:mm:ss"));
}
