Eclipse中使用maven构建SpringMVC

参考1

参考2

核心思想：

步骤：

1. 客户端向spring容器发起一个http请求

2. 发起的请求被前端控制起所拦截(DispatcherServlet)，前端控制器会去找恰当的映射处理器来处理这次请求

3.

4. 在控制器中处理所发送的请求，并以modeandView（属性值和返回的页面）的形式返回给向前端控制器

5. 前端控制器通过查询viewResolver对象来试着解决从控制返回的视图

6. 如果前端控制找到对应的视图，则将视图返回给客户端，否则抛异常。

contextConfigLocation下的value表示配置文件在/WEB-INF/applicationContext.xml；

servlet-mapping下的url-pattern表示以这个结尾的请求会通过这个servlet。（还可以试.jsp,.html等）

applicationContext.xml：

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

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/" />
<property name="suffix" value=".jsp" />
</bean>

</beans>

表示当spring在启动时，回加载这个包下面的所有组件（这就包的自动扫描机制，即spring会将标有@Controller @Component等类加载到spring容器管理中）

ViewResolver是一个使徒解析器，就是我们第一部分提到的springMVC生命周期中的第五步，上面这段的配置的意思就是，当我们从后端控制器中返回的视图时，前端控制器就根据这一段配置来返回一个具体的视图，如后端控制返回的是一个hello，根据上面的配置，最后前端控制器会组并成这样的一个地址：hello.jsp(/代表根目录下),然后从根目录下面查找一个hello.jsp返回客户端。
