Spring Boot基础教程2-RESTfull API简单项目的快速搭建

搭建一个简单的RESTfull API接口项目

demo目录结构如下:

  1. spring-boot-starter-web的引入,其依赖包的学习

 2.spring-boot-devtools的引入,其依赖包的学习

3.代码的实现

public class User {
	private int id;
	private String name;
	private Date date;

	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public Date getDate() {
		return date;
	}

	public void setDate(Date date) {
		this.date = date;
	}
}
@RestController
@RequestMapping(value = "/index")
public class IndexController {

	@RequestMapping
	public String index() {
		return "hello world";
	}

	// @RequestParam 简单类型的绑定,可以出来get和post
	@RequestMapping(value = "/get")
	public HashMap<String, Object> get(@RequestParam String name) {
		HashMap<String, Object> map = new HashMap<String, Object>();
		map.put("title", "hello world");
		map.put("name", name);
		return map;
	}

	// @PathVariable 获得请求url中的动态参数
	@RequestMapping(value = "/get/{id}/{name}")
	public User getUser(@PathVariable int id, @PathVariable String name) {
		User user = new User();
		user.setId(id);
		user.setName(name);
		user.setDate(new Date());
		return user;
	}

}

4.运行项目

直接运行main方法或者使用maven命令: spring-boot:run

测试: http://localhost:8080/index
