SpringMVC程序简单实例


            StringMVC程序简单实例

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。
