# 1、整合原理 #

1.  在SpringMVC配置文件中配置**MVC注解解析器、静态资源页面放行、视图解析器、拦截器**
2.  在web.xml中配置**SpringMVC的前端控制器**、**MVC的编码过滤器**
3.  ***在SpringMVC配置文件中引入Spring的配置文件***
4.  Spring配置文件照常配置

# 2、整合实现 #

#### 2.1 SpringMVC配置文件(springmvc.xml) ####

<?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:mvc="http://www.springframework.org/schema/mvc"
           xmlns:context="http://www.springframework.org/schema/context"
           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">
    
    
        
        <import resource="classpath:applicationContext.xml"/>
    
    
        
        <mvc:annotation-driven/>
    
        
        <mvc:default-servlet-handler/>
    
        
        
    
        
        <mvc:interceptors>
            <mvc:interceptor>
                
                <mvc:mapping path="/**"/>
                
                <mvc:exclude-mapping path="/logincheck"/>   
                <mvc:exclude-mapping path="/login.html"/>   
                <mvc:exclude-mapping path="/static/**"/>  
    
                
                <bean class="com.project.SSM.user4crud.interceptors.UserLoginInterceptors"/>
            </mvc:interceptor>
    
        </mvc:interceptors>
    
    
    </beans>

#### 2.2 web.xml ####
