springMVC配置和使用

----web.xml配置----

<servlet> 
  <servlet-name>springMVC</servlet-name> 
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
  <!-- 
可以自定义servlet.xml配置文件的位置和名称，默认为WEB-INF目录下，
名称为[<servlet-name>]-servlet.xml，如spring-servlet.xml 
  <init-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>/WEB-INF/spring-servlet.xml</param-value> 默认 
  </init-param> 
  -->
  <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。

> 

  <!-- servlet在找不到的时候会去找静态的内容，如jpg,js,css -->
< mvc:default-servlet-handler />

 <!-- 启用spring mvc 注解 -->

<mvc:annotation-driven />

  <!-- 设置使用注解的类所在的jar包 -->
  < context:component-scan base-package= "controller"></ context:component-scan> 
  
  <!-- 完成请求和注解POJO的映射 -->
  < bean class= "org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" /> 
  
  <!-- 对转向页面的路径解析。prefix：前缀， suffix：后缀 -->
 

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

             id = "internalResourceViewResolver" >

         <!-- 前缀 -->

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

         <!-- 后缀 -->

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

</ bean >

----使用----

http://localhost:8080/项目名/mvc/hello

@Controller

@RequestMapping ( "/mvc" )

public class mvcController {

 

     @RequestMapping ( "/hello" )

@RequestMapping

     public String hello(String

name

){       

         return "hello" ;

     }

}
