前提:导包:在lib下导入相关jar包




第一步:在web.xml配置中央控制器






相关代码:



	<!-- 第一步  配置中央控制器-->
	<servlet>
		<servlet-name>springmvc</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>/WEB-INF/springmvc-servlet.xml</param-value>
		</init-param>
	</servlet>
	<servlet-mapping>
		<servlet-name>springmvc</servlet-name>
		<!--struts习惯使用/*,在springmvc不好用-->
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>



第二步骤:创建包 编写Controler 此类需要继承AbstractController





第三步:

WEB-INF,下创建springmvc的核心配置文件。

文件的命名规则:中央控制器(servlet的名称 我们这里叫做springmvc)的名称+“-servlet.xml”

默认位置:WEB-INF下







第四步:在新创建的springmvc-servlet.xml里面配置

1.Controler   2.handlerMapping (多种配置方式)  3.ViewResolver(试图解析器) 4.interceptor(拦截器)


第一种,默认的映射处理器:


springmvc-servlet.xml 代码:

<?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:mvc="http://www.springframework.org/schema/mvc"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
	http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
	http://www.springframework.org/schema/mvc 
	http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd 
	http://www.springframework.org/schema/context 
	http://www.springframework.org/schema/context/spring-context-3.0.xsd 
	http://www.springframework.org/schema/aop 
	http://www.springframework.org/schema/aop/spring-aop-3.0.xsd 
	http://www.springframework.org/schema/tx 
	http://www.springframework.org/schema/tx/spring-tx-3.0.xsd ">
	<!--
		配置controller ,handlerMapping ,ViewResolver(试图解析器),interceptor(拦截器)
	-->
	<!--默认的映射处理器 可以不显示定义-->
	<bean
		class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>
		
	<!-- 使用默认的映射处理器来映射controler  只要在controler 加一个name 值就是 jsp页面上要访问的值 -->
	<!--配置controller-->
	<bean id="testControler" name="/hello.do" class="com.mth.springmvc.TestControler"></bean>

	<!-- 配置 ViewResolver试图解析器-->
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<!-- 前缀指定文件夹的路径-->
		<property name="prefix" value="/WEB-INF/jsp/"></property>
		<!-- 后缀 -->
		<property name="suffix" value=".jsp"></property>
	</bean>





</beans>


第二种,简单的映射处理器:




springmvc-servlet.xml 代码:

<?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:mvc="http://www.springframework.org/schema/mvc"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
	http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
	http://www.springframework.org/schema/mvc 
	http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd 
	http://www.springframework.org/schema/context 
	http://www.springframework.org/schema/context/spring-context-3.0.xsd 
	http://www.springframework.org/schema/aop 
	http://www.springframework.org/schema/aop/spring-aop-3.0.xsd 
	http://www.springframework.org/schema/tx 
	http://www.springframework.org/schema/tx/spring-tx-3.0.xsd ">
	<!--
		配置controller,handlerMapping(映射处理器),ViewResolver(试图解析器),interceptor(拦截器)
	-->
	<!--简单url的映射处理器	适合项目中有很多Controler-->
	<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
		<property name="mappings">
			<props>
				<prop key="/hello.do">testControler</prop>
			</props>
		</property>
	</bean>

	<!--配置controller-->
	<bean id="testControler" class="com.mth.springmvc.TestControler"></bean>

	<!-- 配置 ViewResolver试图解析器-->
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<!-- 前缀指定文件夹的路径-->
		<property name="prefix" value="/WEB-INF/jsp/"></property>
		<!-- 后缀 -->
		<property name="suffix" value=".jsp"></property>
	</bean>

</beans>


第三种,类名映射处理器:

springmvc-servlet.xml 代码:

<?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:mvc="http://www.springframework.org/schema/mvc"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
	http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
	http://www.springframework.org/schema/mvc 
	http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd 
	http://www.springframework.org/schema/context 
	http://www.springframework.org/schema/context/spring-context-3.0.xsd 
	http://www.springframework.org/schema/aop 
	http://www.springframework.org/schema/aop/spring-aop-3.0.xsd 
	http://www.springframework.org/schema/tx 
	http://www.springframework.org/schema/tx/spring-tx-3.0.xsd ">
	<!--
		配置controller,handlerMapping(映射处理器),ViewResolver(试图解析器),interceptor(拦截器)
	-->
	

	<!--第三种 映射处理器,控制类的类名控制器,访问时类名首字母需要小写	-->
	<bean
		class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping">
	</bean>

	<!--配置controller-->
	<bean id="testControler" class="com.mth.springmvc.TestControler"></bean>

	<!-- 配置 ViewResolver试图解析器-->
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<!-- 前缀指定文件夹的路径-->
		<property name="prefix" value="/WEB-INF/jsp/"></property>
		<!-- 后缀 -->
		<property name="suffix" value=".jsp"></property>
	</bean>

</beans>
