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+

3. Spring 配置

xml 复制代码

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"

    <!--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"/>

        <property name="characterEncoding" value="UTF-8"/>
        <property name="templateEngine" ref="templateEngine"/>

</beans>

4. Controller

java 复制代码

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";
    }
}

    <meta charset="UTF-8">
    <title>Hello</title>
</head>
<body>
Hello
</body>
</html>
