SprintBoot入门：https://spring.io/quickstart
初始化创建：https://start.spring.io/，注意依赖添加Spring Web。

注意：想打出的jar包能运行，需要加上excution里面的配置。
启动类
SpringApplication.java
package org.liteng.springtest;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringApplication {
public static void main(String[] args) {
org.springframework.boot.SpringApplication.run(SpringApplication.class, args);
}
}
控制器
TestController.java
package org.liteng.springtest.controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/test")
public class TestController {
@GetMapping("/hello")
public String hello(String name) {
return "hello," + name + "!";
}
}
常用注解
@SpringBootApplication：相当于@Configuration、@EnableAutoConfiguration、@ComponentScan
@RestController：控制器
@GetMapping("/hello")：get请求映射
@RequestParam(value "name", defaultValue
"World")：参数映射
返回静态资源
放在resources/static中的文件可以直接访问。例如resources/static/index.html，可以在浏览器中使用http://localhost:8080/index.html访问。
使用thymeleaf引擎
参考：https://blog.csdn.net/caychen/article/details/79625927
参考：https://www.cnblogs.com/tweixi/p/13902918.html
依赖项：org.springframework.boot:spring-boot-starter-thymeleaf
配置文件：
spring:
thymeleaf:
cache: false #开发过程中建议关闭cache
#encoding: UTF-8 #thymeleaf编码
#suffix: .html # thymeleaf后缀
#content-type: text/html #格式
创建模板resources/templates/thymeleaf.html
成功！
创建控制器
@Controller
@RequestMapping("/thymeleaf")
public class ThymeleafController {
@RequestMapping("/hello1")
public String hello1() {
return "thymeleaf";
}
@RequestMapping("/hello2")
public ModelAndView hello2() {
ModelAndView mv = new ModelAndView();
mv.addObject("hello", "世界，你好！");
mv.setViewName("thymeleaf");
return mv;
}
}
