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

i'm trying create first spring boot application , have issu database connection.

at run, have

java.sql.sqlexception : driver.com.musql.jdbc.driver return null

( complete error @ bottom)

when i'm connecting localhost's database without spring boot working perfectly, tested 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 database created in localhost.

but not working spring boot.

i followed tutorial : http://spring.io/guides/gs/batch-processing/#scratch
