**----web.xml配置----**

<**servlet**>   
  <**servlet-name**>springMVC</**servlet-name**>   
  <**servlet-class**>org.springframework.web.servlet.DispatcherServlet</**servlet-class**>   
    
  <**load-on-startup**>1</**load-on-startup**>   
</**servlet**>   
    
<**servlet-mapping**>   
  <**servlet-name**>springMVC</**servlet-name**>   
  <**url-pattern**>\*.do</**url-pattern**>   
</**servlet-mapping**>

**----springMVC-servlet.xml配置----（src下）**

spring-servlet这个名字是因为上面web.xml中<servlet-name>标签配的值为springMVC（<servlet-name>springMVC</servlet-name>），再加上“-servlet”后缀而形成的springMVC-servlet.xml文件名。

<?xml version="1.0" encoding="UTF-8"?>

    xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance"

     http://www.springframework.org/schema/context/spring-context-3.0.xsd  
</ **A**>"  
>   
  
    
`<` `mvc:default-servlet-handler`  `/>`

`<``mvc:annotation-driven``/>`

< **context:component-scan** base-package= "controller"></ **context:component-scan**>   
    
    
  < **bean** class= "org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

`<` `bean` `class` `=` `"org.springframework.web.servlet.view.InternalResourceViewResolver"`

`            ` `id` `=` `"internalResourceViewResolver"` `>`

`        ` ``

`        ` `<` `property` `name` `=` `"prefix"` `value` `=` `"/WEB-INF/jsp/"` `/>`

`        ` ``

`        ` `<` `property` `name` `=` `"suffix"` `value` `=` `".jsp"` `/>`

`</` `bean` `>`

**----使用----**

**http://localhost:8080/项目名/mvc/hello**

`@Controller`

`@RequestMapping` `(` `"/mvc"` `)`

`public` `class` `mvcController {`
