springBoot返回json数据

在第一篇(https://blog.youkuaiyun.com/codingToMaster/article/details/94354180)的基础上，编写实体类Student:

package com.huawei;

public class Student
{
    private int id;
    private String name;

    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;
    }
}

在HelloController中添加获取student的方法：

/**
 * springBoot默认使用的json解析框架是jackson
 * @return
 */
@RequestMapping("student")
public Student getDemo() {
    Student student = new Student();
    student.setId(1);
    student.setName("张三");
    return student;
}

运行：

注意：spring Boot默认支持jackson
