Spring boot app - How to make database connection? - mysql

Question

I'm trying to create my first Spring Boot application and I have an issu with database connection.
At the run, I have an
java.sql.SQLException : Driver.com.musql.jdbc.Driver which return null
( the complete error at the bottom)
When I'm connecting to my localhost's database without Spring Boot this is working perfectly, I tested that with this piece of code :
try {
Class.forName("com.mysql.jdbc.Driver");
java.sql.Connection connection = DriverManager
.getConnection("jdbc:mysql://127.0.0.1:3306/logsdb","logsdb", "logsdb");
System.out.println("connection ok");
System.out.println(connection.getCatalog());
} catch (SQLException e) {
System.out.println("Connection Failed! Check output console");
e.printStackTrace();
return;
}
This return the database I created in localhost.
But it is not working with Spring boot.
I followed this tutorial : http://spring.io/guides/gs/batch-processing/#scratch

I read a lot of posts on stackoverflow but I wasn't able to find the good solution, if you have an idea..

Answer 1

You have a spelling error in your jdbc url. It should be (notice the :):
spring.datasource.url= jdbc:mysql://localhost:3306/logsdb

Answer 2

Change your property to spring.datasource.url= jdbc:mysql://localhost:3306/logsdb. You missed a : after mysql in spinrg.datasource.url and hence your got the error java.sql.SQLException: Driver:com.mysql.jdbc.Driver#9ff430 returned null for URL:jdbc:mysql//localhost:3306/logsdb
