Spring boot find autowired on another package

Question

I\'m developing a Spring Boot application which uses some Spring Data Repository interfaces:

package test;
@SpringBootApplication
public class Application im         


        

Answer 1

Use a Spring @ComponentScan annotation alongside the SpringBoot @SpringBootApplication and configure a custom base package (you can either specify a list of package names or a list of classes whose package will be used), so for example

@SpringBootApplication
@ComponentScan(basePackages = {"otherpackage", "..."})
public class Application

or

@SpringBootApplication
@ComponentScan(basePackageClasses = {otherpackage.MyClass.class, ...})
public class Application

or since Spring 1.3.0 (Dec. 2016), you can directly write:

@SpringBootApplication(scanBasePackageClasses = {otherpackage.MyClass.class, ...})
public class Application

Note that component scan will find classes inside and below the given packages.

Answer 2

Good to verify the scopes of classes kept in different packages by using @ComponentScan annotation in Spring boot startup custom class.

Also add @Component in modal classes being used to allow framework accessing the classes.
