StringMVC 创建一个简单的StringMVC程序

第一步：导入jar包

第二步，在WEB-INF文件夹下创建spring-servlet.xml文件。

 

<?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:p="http://www.springframework.org/schema/p"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-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  
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
	<!-- 注册aop功能 -->
	<aop:aspectj-autoproxy/>
	
	<!-- 自动扫面com.springmvc目录及其子目录下面所有类文件，自动注入所有带注解的类 -->
	<context:component-scan base-package="com.yxl.*" />
	

	<!-- 处理请求response返回值，如下配置能正确返回字符串型返回值,如返回值为对象，则自动转为json -->
	<bean id="handleAdapter" class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
		<property name="messageConverters">  
		  <list>  
		   <ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器 -->  
		   <ref bean="mappingStringHttpMessageConverter" />
		  </list>  
		</property>
	</bean>
	<bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" /> 
	<bean id="mappingStringHttpMessageConverter" class="org.springframework.http.converter.StringHttpMessageConverter" />

	<!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->
	<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		  <property name="prefix" value="/WEB-INF/jsp/" />
		  <property name="suffix" value=".jsp"></property>
		  <property name="order" value="1"></property>
	</bean>

	<!-- spring文件上传编码 -->
	<bean id="multipartResolver"
		class="org.springframework.web.multipart.commons.CommonsMultipartResolver"
		p:defaultEncoding="utf-8" />
</beans>

第三步：在web.xml文件配置springmvc。

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	id="WebApp_ID" version="2.5">
	<display-name>springmvc1</display-name>
	<welcome-file-list>
		<welcome-file>index.html</welcome-file>
		<welcome-file>index.htm</welcome-file>
		<welcome-file>index.jsp</welcome-file>
		<welcome-file>default.html</welcome-file>
		<welcome-file>default.htm</welcome-file>
		<welcome-file>default.jsp</welcome-file>
	</welcome-file-list>

	<!-- 设置编码 -->
	<filter>
		<filter-name>characterEncodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>UTF-8</param-value>
		</init-param>
		<init-param>
			<param-name>forceEncoding</param-name>
			<param-value>true</param-value>
		</init-param>
	</filter>


	<!-- 配置DispatchcerServlet -->
	<servlet>
		<servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			 <!-- 配置Spring mvc下的配置文件的位置和名称 -->
			<param-name>contextConfigLocation</param-name>
			<param-value>
                /WEB-INF/spring-servlet.xml
            </param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<!-- 配置DispatchcerServlet 拦击路径'/'所有访问都拦截-->
	<servlet-mapping>
		<servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	
</web-app>

第四步：创建一个控制器。
