(1) Placement spring-mvc.xml
Mainly auto scan controller, view mode.
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:p="http://www.springframework.org/schema/p" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd"> <!-- Automatically scan the package, so that SpringMVC thinks that the class annotated with @controller under the package is a controller --> <context:component-scan base-package="com.aheizi.controller"/> <!-- Prevent IE from returning json to download during ajax request--> <bean id="jacksonMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> </list> </property> </bean> <!-- Define the prefix and suffix of the jumped file, view mode configuration --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- My understanding of the configuration here is to automatically add a prefix and suffix to the return string of the action method to become a usable url address--> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> </beans>
(2) Configure Web.xml
Contains spring and mybatis configuration files, coding filters, logging, spring listeners, spring memory overflow prevention listeners, springmvc core configuration and error jump pages.
<?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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>spring_mybatis_springmvc</display-name> <!-- Spring and mybatis configuration files --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:config/spring-mybatis.xml</param-value> </context-param> <!-- encoding filter --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <async-supported>true</async-supported> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- logging (must precede ContextLoaderListener) --> <context-param> <!-- log configuration file path--> <param-name>log4jConfigLocation</param-name> <param-value>classpath:properties/log4j.properties</param-value> </context-param> <context-param> <!-- The refresh interval of the log page --> <param-name>log4jRefreshInterval</param-name> <param-value>6000</param-value> </context-param> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <!-- Spring Listener --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- Prevent Spring memory overflow listener --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- Spring MVC core configuration--> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet> <!-- suffix --> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <!-- Welcome Page--> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> <!-- Error jump page--> <error-page> <!-- Incorrect path--> <error-code>404</error-code> <location>/WEB-INF/errorpage/404.html</location> </error-page> <error-page> <!-- No access, access forbidden --> <error-code>405</error-code> <location>/WEB-INF/errorpage/405.html</location> </error-page> <error-page> <!-- Internal error --> <error-code>500</error-code> <location>/WEB-INF/errorpage/500.html</location> </error-page> </web-app>(3) Create the showUser.jsp page
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>User Index</title> </head> <body> <h3>hello</h3><br/> ${user.userName} </body> </html>
That's ok
