首先，新建一个springboot项目。具体步骤参考之前的SpringBoot入门文章，有详细图文介绍。
目录结构：
package com.cxl.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class HelloController {
@RequestMapping("/hello")
public String inxdex(){
return "Hello world!Hello CXL!!";
}
}
package com.cxl.controller;
import java.util.Map;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class WelcomeController {
// inject via application.properties
@Value("${welcome.message:test}")
private String message = "Hello World";
@RequestMapping("/")
public String welcome(Map<String, Object> model) {
model.put("message", this.message);
return "welcome.html";
}
}
默认项
package com.cxl;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Demochapter1Application {
public static void main(String[] args) {
SpringApplication.run(Demochapter1Application.class, args);
}
}
main.css
h1{
font-size: 20pt;
}
h2{
font-size: 16pt;
}

友情提示：pom里的jar包一定要添加完整了。才能正常显示。否则就算不报错。也无法显示出来。特别是这个：thymeleaf
正常显示的网页效果：
