SpringMVC

SpringMVC的主要依赖引入及其配置文件_com.springsource.org.aopalliance-1.0.0.jar-CSDN博客

引入spring-context依赖Maven会自动引入springbasic的其他jar包
MVC 核心组件

0、（前端控制器DispatcherServlet）（大管家）：

1、处理器映射器

负责查找对应处理的控制器，返回给前端控制器

2、处理器适配器

负责执行前端控制器给他的执行链，调用service，mapper

封装数据模型返回ModelAndView（逻辑视图名称）

3、视图解析器

解析实际视图位置返回前端控制器

把Model数据模型渲染到视图展示在客户端

创建一个springMVC项目：

首先创建一个Maven项目添加如下依赖

创建服务器的web项目

Spring和Servlet的整合-CSDN博客

配置web.xml文件

<servlet>

1）配置springmvc的前端控制器

<servlet-name>springmvc</servlet-name>

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

2）配置springmvc配置文件的位置

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:springmvc.xml</param-value>

</init-param>

</servlet>

<servlet-mapping>

3） 配置可响应路径

<servlet-name>springmvc</servlet-name>

<url-pattern>*.action</url-pattern>

</servlet-mapping>

4）设置编码过滤器

编写springmvc.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       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/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">
<!--        开启注解扫描-->
    <context:component-scan base-package="com.xja.controller"></context:component-scan>
<!--            自动注入处理器映射器，适配器，数据验证，转换器等-->
        <mvc:annotation-driven/>
<!--    视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>
</beans>

编写一个前端控制器DispacherController

模拟一个登录请求

登录请求在web.xml文件中设置处理

调用/login.action路径下的login方法，

在springmvc的配置文件中解析view实际地址
