1. Tomcat 10的servlet包路径变了，javax -> jakarta
2. DispatcherServlet从Spring6 才开始使用jakarta.servlet.http.Servlet
3. Spring6 需要JDK 17+

<!--1、配置前端控制器，读取配置文件-->

3. Spring 配置
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
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.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.xsd">
<!--1、开启注解扫描-->
<context:component-scan base-package="com.ityj.springmvc"/>
<mvc:annotation-driven/>
<!-- 2. 配置thymeleaf视图解析器-->
<bean id="springResourceTemplateResolver" class="org.thymeleaf.spring6.templateresolver.SpringResourceTemplateResolver">
<property name="prefix" value="/WEB-INF/templates/"/>
<property name="suffix" value=".html"/>
<property name="templateMode" value="HTML"/>
<property name="characterEncoding" value="UTF-8"/>
</bean>
<bean id="templateEngine" class="org.thymeleaf.spring6.SpringTemplateEngine">
<property name="templateResolver" ref="springResourceTemplateResolver"/>
</bean>
<bean id="viewResolver" class="org.thymeleaf.spring6.view.ThymeleafViewResolver">
<property name="order" value="1"/>
<property name="characterEncoding" value="UTF-8"/>
<property name="templateEngine" ref="templateEngine"/>
</bean>
</beans>
4. Controller
package com.ityj.springmvc.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class HelloController {
@GetMapping("/hello")
public String hello() {
System.out.println("hello");
return "hello";
}
}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Hello</title>
</head>
<body>
Hello
</body>
</html>
6. 部署到Tomcat并测试
