Java Serialization with Jackson Homework Answer

Homework Answer for Java Serialization with Jackson

Problem1

通过使用Jackson注解或者其他定制化手段

使得EventController中的两个接口，能够接收和返回如下格式的JSON：

{
    "id": "1",
    "name": "下载文件",
    "type": "D",
    "time": 1590050488701,
    "userId": "3",
    "userName": "张三"
}

其中时间是毫秒为单位的时间戳

Problem2

要求PersonController返回Person时：

• 当age字段为null时，返回0
• 当hobby字段为null时，忽略该字段

即当age和hobby不为null时，正常返回：

{
    "id": "1",
    "age": 18,
    "name": "张三",
    "hobby": "打篮球"
}

当age和hobby为null时，返回：

{
    "id": "1",
    "age": 0,
    "name": "张三"
}
