First configure the pom file, you only need to reference three jar package files:
<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/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.rybt.kpi</groupId> <artifactId>api</artifactId> <packaging>war</packaging> <version>1.0-SNAPSHOT</version> <!-- constant --> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <spring.version>3.2.6.RELEASE</spring.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework/spring-web --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> </dependencies> <build> <finalName>api</finalName> </build> </project>
web.xml configuration:
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"> <display-name>rybt.kpi.api</display-name> <!-- The contextConfigLocation parameter is used to specify that the Spring Bean configuration file is configured in the WEB-INF directory by default --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/*.xml</param-value> </context-param> <!-- Configure the spring core listener, the default will use /WEB-INF/applicationContext.xml as the configuration file--> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>rybt.kpi.api</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- You can customize the location and name of the servlet.xml configuration file, the default is in the WEB-INF directory, the default name is [<servlet-name>]-servlet.xml, such as spring-servlet.xml --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>rybt.kpi.api</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>rybt.kpi.api</servlet-name> <url-pattern>/home/index</url-pattern> </servlet-mapping> <!-- Let the files with the following suffixes not take the mvc route--> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>/static/*</url-pattern> </servlet-mapping> <!-- Default page --> <welcome-file-list> <welcome-file>home/index</welcome-file> </welcome-file-list> </web-app>
Another spring-mvc.xml configuration:
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <!-- The following is the location of the configuration scan package, the package name is com.maskkk, that is to say, our attempt parser should be placed under the com.maskkk package. --> <context:component-scan base-package="com.rybt.kpi.controller" /> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- prefix, our view files should be placed in the /WEB-INF/view/ directory, here we need to create a view folder under WEB-INF --> <property name="prefix" value="/WEB-INF/views/" /> <!-- Set the suffix to .jsp --> <property name="suffix" value=".jsp" /> </bean> </beans>
Finally, write a class for the controller layer:
package com.rybt.kpi.controller; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; @Controller @RequestMapping("/home") public class HomeController { @RequestMapping(value="/index",method = {RequestMethod.GET,RequestMethod.POST}) public String index(Model model){ return "home/index"; } }
By the way, you still need an index.jsp page, and you're done;
Finally, here is the code structure diagram:
