## 2、添加Web，完成如下配置 ##

## 3、配置web.xml ##

<servlet>
            <servlet-name>springmvc</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

            </init-param>
            <load-on-startup>1</load-on-startup>
        </servlet>
        <servlet-mapping>
            <servlet-name>springmvc</servlet-name>

            <aop:advisor advice-ref="txAdvice" pointcut-ref="pointCut"/>
        </aop:config>
    
    </beans>

## 5、配置springmvc-servlet.xml ##

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            
            <property name="prefix" value="/"/>
            <property name="suffix" value=".jsp"/>
        </bean>
    
        
        <mvc:annotation-driven></mvc:annotation-driven>
    
        
        <mvc:annotation-driven>
            <mvc:message-converters register-defaults="true">
                
                <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                    <property name="supportedMediaTypes">
                        <list>

            </mvc:message-converters>
        </mvc:annotation-driven>
    
    
        
        <context:component-scan base-package="com.jie.controller"></context:component-scan>
    
        
        <mvc:default-servlet-handler></mvc:default-servlet-handler>
    
        
        <mvc:resources mapping="/js/**" location="/forward/js/"/>
        <mvc:resources mapping="/images/**" location="/forward/images/"/>
        <mvc:resources mapping="/css/**" location="/forward/css/"/>
        <mvc:resources mapping="/js/**" location="/background/js/"/>
        <mvc:resources mapping="/images/**" location="/background/images/"/>
        <mvc:resources mapping="/css/**" location="/background/css/"/>
    
        
        <mvc:interceptors>
        <mvc:interceptor>
            
            <mvc:mapping path="/**"/>
            <mvc:exclude-mapping path="/**/fonts/**"/>

    </mvc:interceptors>
    
    
        
        <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
            
            <property name="maxUploadSize">
                <value>1048576</value>
            </property>
        </bean>

## 6、db.properties配置 ##

（最好是先建立hibernate）

dbcp.driverClassName=com.mysql.jdbc.Driver
    dbcp.url=jdbc:mysql://localhost:3306/数据库名?useSSL=true
    dbcp.username=root
    dbcp.password=970817
    dbcp.maxIdle=100
    dbcp.initialSize=5

## 7、注解方式生成hibernate ##

## 8、登录拦截器 ##

package com.jie.controller;
    
    import org.springframework.web.servlet.HandlerInterceptor;
    import org.springframework.web.servlet.ModelAndView;
    
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    
    public class LoginInterceptor implements HandlerInterceptor {
        @Override
        public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
            Object user = request.getSession().getAttribute("USER_SESSION_KEY");
            String path = request.getContextPath();
            String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
            if (user == null) {
                System.out.println("尚未登录，调到登录页面");
                response.sendRedirect(basePath+"background/login.html");
                return false;
            }
            return true;
        }
    
        @Override
        public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
            System.out.println("postHandle");
        }
    
        @Override
        public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
            System.out.println("afterCompletion");
        }
    }

基本配置已经完成，开始你的项目吧！
