本文介绍如何在SpringBoot项目中配置Thymeleaf模板引擎，实现页面的渲染和跳转。通过创建TestController类，添加了返回页面的方法，并在pom.xml中引入Thymeleaf依赖。同时，通过MyWebMvc类配置了默认跳转到login.html页面。

在TestController类中添加返回页面的方法

package com.example.demo.demo1017;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class TestController {

    @RequestMapping("/hello")
    @ResponseBody
    public String hello(){
        return "hello springboot!";
    }

    @RequestMapping("/login")
    public String login(){
        return "login";
    }

}

在pom.xml文件中引入thymeleaf的包

<?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">

            </configuration>
         </plugin>
      </plugins>
   </build>


</project>

添加login.html页面

新建MyWebMvc类

package com.example.demo.demo1017.config;


import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

@Configuration
public class MyWebMvc extends WebMvcConfigurationSupport {

    //系统先跳转login.html页面
    @Override
    protected void addViewControllers(ViewControllerRegistry registry) {
        //super.addViewControllers(registry);
       registry.addViewController("/").setViewName("login");
    }

}

启动服务，访问地址
