How to save map objects in Java to MySQL database

I have Java map (string and ints) objects and I want to save them to the database

Solution

You actually asked two different questions:

>How to save map objects to a database

You need to create a database and an appropriate table You can serialize a map as a binary object and store it in the database as a blob However, it is better to create a table entry for each object in the map You need to use the JDBC API to communicate with the database

>How to compress the gross to take up less space in the hard disk?

You need to map the serialize map to a file The map will be saved in a binary file, and you can try using compress
