springmvc的核心servlet

第一种：[servlet-name]-servlet.xml ,比如：springmvc-servlet.xml

1.web.xml

<servlet>
  <servlet-name>springmvc</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
  <servlet-name>springmvc</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>

2.WEB-INF文件夹下的建立springmvc-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">

    <!-- 配置自定义扫描包 -->
    <context:component-scan base-package="com.hairui.web"></context:component-scan>

    <!-- 映射物理路径 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>

</beans>

第二种是：改变命名空间 namespace,必须配置文件在放入在web-inf目录下。

1.web.xml

1

<servlet>
  <servlet-name>springmvc</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <init-param>
      <param-name>namespace</param-name>
      <param-value>配置文件名XXXX(不带后缀)</param-value>
  </init-param>
</servlet>
<servlet-mapping>
  <servlet-name>springmvc</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>

2.WEB-INF文件夹下的建立配置文件XXXX.xml，文件名与web.xml中的对应

第三种是通过:contextConfigLocation

1.web.xml

<servlet>
  <servlet-name>springmvc</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath*:配置文件名XXXX.xml</param-value>
  </init-param>
</servlet>
<servlet-mapping>
  <servlet-name>springmvc</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>

2.reaourcea文件夹下的建立配置文件XXXX.xml，文件名与web.xml中的对应
