播放2.3 Scala-MYSQL出现问题

Question

I am currently learning the Play Framework with MYSQL+Slick.

I have tried this Github sample to understand the MYSQL+Slick communication.

• Download the source
• Run the command activator clean compile run
• Opened in browser at http://localhost:9000

I am getting the exception below, even though I gave the correct DB credentials and DB.

play.api.Configuration$$anon$1: Configuration error[Cannot connect to database [models]]

Does anybody know how I can resolve this issue?

Answer 1

Please take the following actions:

1. In mysql, under root user:

    CREATE USER 'test1'@'localhost' IDENTIFIED BY 'mypass'; CREATE DATABASE emp; GRANT ALL ON emp.* TO 'test1'@'localhost'; 

2. Ensure you can login as 'test1' and have access to the emp database:

    mysql -utest1 -pmypass use emp 

3. Change credentials in your conf/application.conf :

    db.models.user="test1" db.models.pass="mypass" ... db.default.user="test1" db.default.pass="mypass" ... 

Then run your application. This should work, at least without connection problems.
