SSM:SpringMvc(完成数据的封装,页面的跳转的逻辑) ?? ??? ?? ?Spring() ?? ??? ?? ?Mybatis(持久化框架。ORM Object Relative Mapping 对象关系映射)
1.引入springmvc的相关jar
**2.在web.xml中配置DispatcherServlet
<servlet>
??? <servlet-name>springMVC-annotation</servlet-name>???
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 将springMVC-annotation-servlet放在创建的resource文件中配置的路径 -->
??? <init-param>
??? ??<param-name>contextConfigLocation</param-name>
??? ??<param-value>classpath:springMVC-annotation-servlet.xml</param-value>
??? </init-param>
? </servlet>
? <servlet-mapping>
??? <servlet-name>springMVC-annotation</servlet-name>
??? <url-pattern>*.do</url-pattern>
? </servlet-mapping>
**3.配置springMVC-annotion的配置文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
?????xmlns:mvc="http://www.springframework.org/schema/mvc"
?????xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
?????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/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">
?????<!-- 包扫描 -->
?????<context:component-scan base-package="com.hw.lb.controller.annotation"></context:component-scan>
?????<!-- 启动注解器 -->
?????<mvc:annotation-driven/>?
?????<!-- 配置视图解析器 -->
? ????<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
? ?????????<property name="prefix" value="/WEB-INF/view/"/>
? ?????????<property name="suffix" value=".jsp"/>
? ????</bean>
</beans>
1.客户发出请求。例如 http://localhost:8080/SpringMVC-01/my.do
2.到达web.xml文件中DispatcherServlet.查看是否符合url的要求
3.DispatcherServlet就会查询springmvc的配置文件。(找HandlerMapping)
根据bean的名称查找相应的controller
4.找到我的MyController类。执行该类中handleRequestInternal方法。
5.根据返回的modelAndView在找springmvc配置文件中视图解析器。
6.视图解析器吧viewName和prefix以及suffix做一个拼接,把拼接的页面展示给客户
