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
