Local connection to remote server database under Windows platform (I)

Continued springboot, After creating users and databases , Let's start writing the remote connection database project , Before realizing remote connection to database , Several aspects need to be certified ：

1、 In order to make the remote connection data safe , Created a new one called 【xiaochun】 Users of , And endowed with the right 【spring】 Operation permissions of the database ; reflection ： Why not use 【root】 What about user connections ？ Then how to manage users ？

2、Spring Boot What is it? ？Spring Boot By Pivotal A new framework from the team , It is designed to simplify the new Spring Initial setup and development of the application . The framework is configured in a specific way , This eliminates the need for developers to define boilerplate configurations .

One 、 Create a remote login user

select * from information_schema.user_privileges;

Show all users ;

drop user 'xiaochun'@'localhost';

Delete the name  【xiaochun】 Users of ;

flush privileges; 

take effect ;

create user 'xiaochun'@'%' identified by ' password ';

//'%'： Create user , And give remote login

 flush privileges;

take effect ;

grant all privileges on spring.* to 'xiaochun'@'%';

Give users 【xiaochun】 To the database 【spring】 All operation permissions of ;

take effect ;

flush privileges; 

take effect ;

exit;

sign out

Two 、 Remote connection

Use 【mysql workbench】 land , as follows ：

Verify that you have the right spring Database permissions ;

 

This section completes , The next chapter introduces , How to implement... In code .

reflection ：grant all privileges on *.* to 'xiaochun'@'%';

Why can't you write it like this ？
