1、导入jar包
1.1、maven坐标

2、约束
2.1、web.xml
3.0
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0">
web-app>
4.0
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
version="4.0">
web-app>
2.2、springmvc.xml
代码如下（示例）：
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
beans>
3、web.xml常用功能
3.1、springMVC的编码过滤器
<filter>
<filter-name>CharacterEncodingFilterfilter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>
<init-param>
<param-name>encodingparam-name>
<param-value>UTF-8param-value>
init-param>
<init-param>
<param-name>forceEncodingparam-name>
<param-value>trueparam-value>
init-param>
filter>
<filter-mapping>
<filter-name>CharacterEncodingFilterfilter-name>
<url-pattern>/*url-pattern>
filter-mapping>
3.2、获取请求方式过滤器
<filter>
<filter-name>HiddenHttpMethodFilterfilter-name>
<filter-class>org.springframework.web.filter.HiddenHttpMethodFilterfilterclass>
filter>
<filter-mapping>
<filter-name>HiddenHttpMethodFilterfilter-name>
<url-pattern>/*url-pattern>
filter-mapping>
3.3、前端控制器
<servlet>
<servlet-name>dispatcherServletservlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet
servlet-class>
<init-param>
<param-name>contextConfigLocationparam-name>
<param-value>classpath:springmvc.xmlparam-value>
init-param>
<load-on-startup>1load-on-startup>
servlet>
<servlet-mapping>
<servlet-name>dispatcherServletservlet-name>
<url-pattern>/url-pattern>
servlet-mapping>
3.4、监听器Spring整合SpringMVC
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener
listener-class>
listener>
<context-param>
<param-name>contextConfigLocationparam-name>
<param-value>classpath:applicationContext.xmlparam-value>
context-param>
4、springmvc.xml常用功能
4.1、扫面组件
组件：我们自己写的类，使用注解
@Component
@Controller
@Service
@Repository
注册到spring中
<context:component-scan
base-package="com.tianyu">
<context:include-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
context:component-scan>
4.2、视图解析器
InternalResourceViewResolver
<bean id="internalResourceViewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp">property>
bean>
ThymeleafViewResolver
<bean id="viewResolver"
class="org.thymeleaf.spring5.view.ThymeleafViewResolver">
<property name="order" value="1"/>
<property name="characterEncoding" value="UTF-8"/>
<property name="templateEngine">
<bean class="org.thymeleaf.spring5.SpringTemplateEngine">
<property name="templateResolver">
<bean class="org.thymeleaf.spring5.templateresolver.SpringResourceTemplateResolver">
<property name="prefix" value="/WEB-INF/templates/"/>
<property name="suffix" value=".html"/>
<property name="templateMode" value="HTML5"/>
<property name="characterEncoding" value="UTF-8"/>
bean>
property>
bean>
property>
bean>
4.3、静态资源处理
方式一
<mvc:default-servlet-handler/>
方式二
<mvc:resources location="/css/" mapping="/css/**">mvc:resources>
<mvc:resources location="/images/" mapping="/images/**">mvc:resources>
<mvc:resources location="/js/" mapping="/js/**">mvc:resources>
4.4、mvc注解驱动
<mvc:annotation-driven>
<mvc:message-converters register-defaults="true">
<bean class="org.springframework.http.converter.StringHttpMessageConverter">
<constructor-arg value="UTF-8"/>
bean>
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="objectMapper">
<bean class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean">
<property name="failOnEmptyBeans" value="false"/>
bean>
property>
bean>
mvc:message-converters>
mvc:annotation-driven>
4.5、视图控制器
<mvc:view-controller path="/" view-name="index">mvc:view-controller>
4.6、文件上传解析器
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding" value="utf-8"/>
<property name="maxUploadSize" value="10485760"/>
<property name="maxInMemorySize" value="40960"/>
bean>
4.7、拦截器
方式一
<mvc:interceptors>
<bean class="pers.tianyu.interceptor.FirstInterceptor">bean>
mvc:interceptors>
方式二
<bean id="firstInterceptor" class="pers.tianyu.interceptor.FirstInterceptor">bean>
<mvc:interceptors>
<ref bean="firstInterceptor">ref>
mvc:interceptors>
方式三
<bean id="firstInterceptor" class="pers.tianyu.interceptor.FirstInterceptor">bean>
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/**"/>
<mvc:exclude-mapping path="/testRequestEntity"/>
<ref bean="firstInterceptor">ref>
mvc:interceptor>
mvc:interceptors>
4.8、异常解析器
<bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
<property name="exceptionMappings">
<props>
<prop key="java.lang.ArithmeticException">errorprop>
props>
property>
<property name="exceptionAttribute" value="ex">property>
bean>
