1. Import the configuration file pom.xml
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.xingxue.springmvc</groupId> <artifactId>springmvc-day1</artifactId> <version>1.0-SNAPSHOT</version> <packaging>war</packaging> <dependencies> <!-- Spring related dependencies --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.0.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>4.0.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>4.0.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.0.4.RELEASE</version> </dependency> <!-- The spring web module provides a listener to start the spring container --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>4.0.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.0.4.RELEASE</version> </dependency> <!--Also import other related dependencies--> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.0.1</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>javax.servlet.jsp-api</artifactId> <version>2.2.1</version> <scope>provided</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.2</version> <configuration> <path>/</path> <port>80</port> </configuration> </plugin> </plugins> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> <filtering>false</filtering> </resource> <resource> <directory>src/main/resources</directory> <includes> <include>**/*.xml</include> <include>**/*.properties</include> </includes> <filtering>false</filtering> </resource> </resources> </build> </project>
2. Configuration resource ""applicationContext-mvc.xml The name of this configuration file is arbitrarily taken
<?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: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.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<context:component-scan base-package="com.xingxue"/>
<!--To configure this tag in the container, the @RequestMapping annotation will take effect after configuration-->
<mvc:annotation-driven/>
<!--After configuring this tag, the front-end controller configured in web.xml is intercepted as /, and static resources can be processed -->
<mvc:default-servlet-handler/>
<!--Configure the internal resource view resolver-->
//It is to string together the value returned in the controller/WEB-INF/jsps/ok.jsp
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsps/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
three. configure web.xml
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
<!--Configure the front controller of springmvc
DispatcherServlet
-->
<servlet>
<servlet-name>mvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>mvc</servlet-name>
<!--If / is configured here, the web application cannot process static resources css html-->
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
Four. The access path in writing demo.jsp is the path to be configured in our controller
<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %>
<html>
<head>
<title>demo</title>
</head>
<body>
<a href="${pageContext.request.contextPath}/demo1">点我，访问controller</a>
</body>
</html>
Five configure the controller
package com.xingxue.springmvc.web.controller;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class DemoController {
@RequestMapping(value = "demo1")//This path is the path passed by the bound jsp page and has nothing to do with the method
//The value attribute in the RequestMapping annotation is used to map the uri address, and the uri address maps the demo1 method
public String demo1(){
System.out.println("demo1 method executed....");
return "ok"; //The returned string is also the logical view name
}
@RequestMapping(value = "demo2")
public String demo2(){
System.out.println("demo2 method executed...");
return "ok";//The returned name is the name of the jsp or html in the future
}
}
6. Return to the path jsps/ok.jsp displayed on the page
