快速搭建Spring-boot Demo

快速搭建Spring-boot Demo

环境:

jdk: 1.8

ide: Spring Tool Suite

maven : 3.2 地址为阿里的maven仓库

步骤:

1 : file-->new--->Spring Starter Project

2: 完成上述步骤后可以看到项目结构为:

再 com.example包下新建两个包com.example.controller , com.example.entiry

Controller中代码如下:

@RestController
@RequestMapping("/hello")
public class ExampleController {
	@GetMapping("/home")//@GetMapping("/home")相当于@RequestMapping(value = "/home" ,method = requestMethod.Post)
	public Person home(){
		Person person = new Person();
		person.setId(222L);
		person.setName("张三");
		person.setAge(20);
		return person;
	}
}

Person基本结构:

package com.example.entity;

public class Person {
	private Long id;
	private String name;
	private String add;
	private int age;

	public Long getId() {
		return id;
	}

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

	public String getName() {
		return name;
	}

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

	public String getAdd() {
		return add;
	}

	public void setAdd(String add) {
		this.add = add;
	}

	public int getAge() {
		return age;
	}

	public void setAge(int age) {
		this.age = age;
	}

}

选中DemoApplication.java 右键run as Spring Boot App,启动完成后默认端口为8080

在浏览器中输入:http://localhost:8080/hello/home

如上显示,那么一个简单的Demo就完成了,关于controller和DemoApplication.java 类中的注解我们下面再一起学习
