springboot整合 Thymeleaf模板

首先引入maven jar依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>
<groupId>net.sourceforge.nekohtml</groupId>
            <artifactId>nekohtml</artifactId>
            <version>1.9.22</version>
        </dependency>

接着在application.properties内配置 thymeleaf

#设置thymeleaf  注意：一定要在web后面添加一个 斜杠 /，否则找不到文件
spring.thymeleaf.prefix=classpath:/web/
spring.thymeleaf.suffix=.html
#设置thymeleaf不按照HTML5严格的检查标签
spring.thymeleaf.mode=LEGACYHTML5

模板默认还是放在templates文件夹下，这里我修改到web文件夹下面了

package com.example.demo.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.example.demo.entity.Student;

@Controller
@RequestMapping("/student/")
public class StudentController {

    @RequestMapping("show")
    public String show(Model model) {

        Student stu = new Student();
        stu.setId(1001);
        stu.setName("小明");
        model.addAttribute("student", stu);

        model.addAttribute("str", "this is spring boot freemarker");
        return "show";
    }

}
