Save generic object in database

Question

My model is like:

public class MyModel{
    private String mId;
    private String mName;
    T mAnObject;
}

How can I store T object in database .

Answer 1

如果您需要保存特定的属性，只要做到这一点，否则你可以把它序列化到JSON ，作为一个选项（如证明这里 ）。

Answer 2

Example: Object myObj has three properties: String title, String subtitle, String text

1 - You can save them as separate database rows and then when you read from the database you recombine them to create your Object.

2 - You can also use Json to save the properties, this way you only need to store a single String in the database and when you read from the database convert the Json String to your Object.
