創建一個maven並添加web框架
在pom文件中添加依賴
<!-- 依賴 -->
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>5.2.2.RELEASE</version>

在web.xml中配置攔截器
<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>
配置springmvc.xml文件
<?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/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<context:component-scan base-package="cn.edu.zut.controller"/>
<mvc:annotation-driven></mvc:annotation-driven>
<!-- 靜態資源過濾 -->
<mvc:default-servlet-handler/>
<!-- 視圖解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
id="internalResourceViewResolver">
<!-- 前綴 -->
<property name="prefix" value="/WEB-INF/jsp/"/>
<!-- 後綴 -->
<property name="suffix" value=".jsp"/>
</bean>
</beans>
通過註解編寫第一個Controller
package cn.edu.zut.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@SuppressWarnings("all")
@Controller
public class HelloController {
@RequestMapping("/test")
public String test(Model model){
model.addAttribute("msg","Hello SpringMVC");
return "test";
}
}
編寫index.jsp和test.jsp(注意根據視圖解析器創建這個test.jsp)

Tomcat發佈測試
可能存在的問題
在發佈的時候可能會存在url請求找不到的時候,這是因爲我們在發佈的時候沒有把jar引進去。解決方法很簡單,在WEB-INF下創建lib目錄,在lib下引入所有jar即可。如圖所示。
