spring整合springMVC主要需要配置兩個xml配置檔案，web.xml和springmvc.xml

步驟：

一、配置springmvc.xml

主要配置：

1.配置自動掃描的包：掃描controller層

2.配置springmvc的註解驅動，不開啟此驅動無法使用RequestBody，ResponseBody等註解

3.配置檢視解析器

4.配置過濾靜態資源等：目的是讓靜態資源不被攔截

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
 

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="
       http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd"
 
>

    <!--配置自動掃描的包-->
    <context:component-scan base-package="com.xj.controller"/>

    <!--配置springmvc的註解驅動-->
    <mvc:annotation-driven/>

    <!--配置檢視解析器-->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
 

        <property name="prefix" value="/WEB-INF/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <!--過濾靜態資源-->
    <mvc:resources mapping="/css/**" location="/css/"/>
    <mvc:resources mapping="/images/**" location="/images/"/>
    <mvc:resources mapping="/js/**" location="/js/"/>
</beans>

二、配置web.xml

主要配置：

1.配置監聽器Listener

作用：用於載入spring配置檔案（dao和service層的ioc容器）

2.配置過濾器Filter

characterEncodingFilter：用來指定請求或者響應的編碼格式

其中encoding用來指定編碼格式，forceEncoding表示是否強制request/response的編碼格式也是encoding格式

3.配置前端控制器

作用：

1.載入springmvc配置檔案（controller層的ioc容器）

2.攔截請求
