一、引入必要类库

spring-context

spring-context-support

spring-webmvc：引入该包后，maven 会自动解析依赖，引入 spring-web 等包。

二、web 配置

在 java config 配置方式中，我们就不需要在 web.xml 中配置监听及servlet 等节点了，这里我们仍然使用 servlet 3.0 API 。

1.web.xml

<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="
http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID"
version="3.0">
</web-app>

三、用 JavaConfig 替代 web.xml 中 servlet 配置及监听配置

public class WebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer：

WebInitializer继承关系链：

WebInitializer -->AbstractAnnotationConfigDispatcherServletInitializer -->AbstractDispatcherServletInitializer -->

AbstractContextLoaderInitializer -->WebApplicationInitializer

实现 WebApplicationInitializer 接口，就等同于 web.xml 配置

@Override public void onStartup ：

web.xml 核心的相关配置，可再此方法中重写自定义的配置，如：<filter> 可用 FilterRegistration.Dynamic encodingFilter 此种方式来配置。

@Override protected Class<?>[] getRootConfigClasses ：

重写此方法，以替代 spring-context.xml ,在这个方法中返回的类类型数组可配置上下文中需要的 bean ，如数据库，缓存等等。

@Override protected Class<?>[] getServletConfigClasses：

重写此方法，以替代 spring-mvc.xml ，在这个方法中返回的类型数组可配置 spring 中视图解析器，http message converter 等框架需要的 bean。

@Override protected String[] getServletMappings ：

重写此方法，就相当于 <servlet-mapping> 节点等同的功能，可指定站点根路径。

public class WebConfig extends WebMvcConfigurerAdapter ：

@EnableWebMvc：注解会开启一些默认配置，如：ViewResolver MessageConverter 等,若无此注解，重写 WebMvcConfigurerAdapter 方法无效。

@ComponentScan：会扫描指定包中的类，根据注解，将特定类初始化为上下文中需要的 bean 。

@Override public void addViewControllers ：

重写 addViewControllers 简化页面快捷转向，这样就可以不用配置 Controller 了（就是那些仅返回一个页面路径的简单 controller ）。

@Bean public InternalResourceViewResolver viewResolver ：

配置JSP视图解析器

@Bean public MultipartResolver multipartResolver ：

配置springMVC处理上传文件的信息

@Override public void addResourceHandlers ：

配置静态文件处理
