怎么搭建一个SpringMVC工程？针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。

一、创建项目

1、新建一个项目名为：springmvc-demo-yuyongqing

右键项目名选择Add Framework Support

2、选择Web Application

3、配置SpringMVC

pom.xml

<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.13.2</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>5.2.13.RELEASE</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>4.0.1</version>
<scope>provided</scope>
</dependency>
</dependencies>

刷新maven后再加入如下图所示代码

<build>
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>
</build>

二、配置核心文件

1、

<?xmlversion="1.0"encoding="UTF-8"?>
<beansxmlns="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
https://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
https://www.springframework.org/schema/mvc/spring-mvc.xsd
">

<!--beandefinitionshere-->

2、添加SpringMVC配置内容

<!--自动扫描包，让指定包下的注解生效,由IOC容器统一管理-->
<context:component-scanbase-package="controller"/>

<!--1加载注解驱动-->
<mvc:annotation-driven/>
<!--2静态资源过滤-->
<mvc:default-servlet-handler/>
<!--3视图解析器-->
<beanid="internalResourceViewResolver"class=
"org.springframework.web.servlet.view.InternalResourceViewResolver">
<propertyname="prefix"value="/WEB-INF/jsp/"/>
<propertyname="suffix"value=".jsp"/>
</bean>

3、Controller层

新建一个HelloController类

packagecontroller;

@Controller
publicclassHelloController{

@RequestMapping("/hello")
publicStringhello(Modelmodel){
//Model封装数据
model.addAttribute("msg","HELLOMYFIRSTSPRINGMVCPROJECT");

//返回的字符串就是视图的名字会被视图解析器处理
return"hello";
}
}

4、JSP

在JSP包下新建hello.jsp

<%@pagecontentType="text/html;charset=UTF-8"language="java"%>
<html>
<head>
<title>Title</title>
</head>
<body>
${msg}
</body>
</html>

三、web.xml

1、配置前端控制器

<!--配置前端控制器-->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

2、配置初始化参数

<!--配置初始化参数-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationcontext.xml</param-value>
</init-param>

3、设置启动级别

<!--设置启动级别-->
<load-on-startup>1</load-on-startup>
</servlet>

4、设置SpringMVC拦截请求

<!--设置SpringMVC拦截请求-->
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern><!--拦截除.jsp的请求-->
</servlet-mapping>

5、乱码过滤

<!--乱码过滤-->
<filter>
<filter-name>encodingFilter</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>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

6、运行web

打包File→Project Structure
