idea中使用maven工程搭建SpringMVC框架
一、创建工程
1、在idea中点击file-->new-->project
2、选择maven,点击next
3、输入项目名称,更改groupid
二、搭建SpringMVC框架
1、打开pom.xml, 引入依赖,打包方式设置为war
<?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"> <parent> <artifactId>SpringMVC</artifactId> <groupId>org.example</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <groupId>com.fan.mvc</groupId> <artifactId>springMVC-demo2</artifactId> <!--打包方式--> <packaging>war</packaging> <dependencies> <!-- SpringMVC --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>5.3.1</version> </dependency> <!-- 日志 --> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.2.3</version> </dependency> <!-- ServletAPI --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency> <!-- Spring5和Thymeleaf整合包 --> <dependency> <groupId>org.thymeleaf</groupId> <artifactId>thymeleaf-spring5</artifactId> <version>3.0.12.RELEASE</version> </dependency> </dependencies> </project>
2、在main中创建一个Directory-->webapp
3、创建web.xml:
a.点击file-->Project Structure
b.按照下图完成web.xml的创建,注:在点击完web.xml之后,选择文件位置时,要在项目名称和WEB-INF之间输入刚刚创建好的webapp的位置:srcmainwebapp(如下面第二个图所示)
4、配置web.xml
<?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_4_0.xsd" version="4.0"> <!--注册前端控制器DispatcherServlet--> <servlet> <servlet-name>DispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springMVC.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>DispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
5、创建请求控制器
a.在java文件下创建controller包,在包内创建TestController类
b.在类的名字上写上注解@Controller
@Controller public class TestController { }
6、创建配置文件
a.在resources中创建springMVC.xml文件
b.扫描组件,配置视图解析器
<?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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd"> <!--扫描组件--> <context:component-scan base-package="com.fan.mvc.controller"></context:component-scan> <!--配置thymeleaf的视图解析器--> <!-- 配置Thymeleaf视图解析器 --> <bean id="viewResolver" class="org.thymeleaf.spring5.view.ThymeleafViewResolver"> <property name="order" value="1"/> <property name="characterEncoding" value="UTF-8"/> <property name="templateEngine"> <bean class="org.thymeleaf.spring5.SpringTemplateEngine"> <property name="templateResolver"> <bean class="org.thymeleaf.spring5.templateresolver.SpringResourceTemplateResolver"> <!-- 视图前缀 --> <property name="prefix" value="/WEB-INF/templates/"/> <!-- 视图后缀 --> <property name="suffix" value=".html"/> <property name="templateMode" value="HTML5"/> <property name="characterEncoding" value="UTF-8" /> </bean> </property> </bean> </property> </bean> </beans>
三、测试
1、在WEB-INF中创建templates文件,在此文件创建index.html,并完场一下代码
<!DOCTYPE html> <html lang="en" xmlns:th="http://www.thymeleaf.org"> <head> <meta charset="UTF-8"> <title>首页</title> </head> <body> <h1>首页</h1> </body> </html>
2、在请求控制器(TestController)中写请求方法
@RequestMapping("/") public String index(){ return "index"; }
3、启动服务器,并启动该项目(在浏览器地址栏输入)
4、运行成功页面
