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。
