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。
