I start with learning Spring and I create basic project which creates database, insert values and next print it in web browser. My problem is that when I have RestController in the same package like main class - its OK, but I want distribute it to other package and when I create new package, move the RestController it doesn't work. Let met explain:
My project looks like:
|-Springtestv_01
|-src/main/java
|--com.person <-- it's a main package
|-Main.java
|-Person.java
|-PersonLineRunner.java
|-PersonRepository.java
|-PersonController.java
|-com.controller <-- second package, I want put here PersonController.java
|-src/main/resources
|-data.sql
pom.xml
My controller looks:
@RestController
public class PersonController {
@Autowired PersonRepository personRepository;
@RequestMapping("/persons")
Collection<Person> persons(){
return this.personRepository.findAll();
}
}
When everything is in com.person
package, I write in web brower http://localhost:8080/persons and it works correctly...
But I Want move PersonController.java
to com.controller
package, and when I moved it, my webbrowers calls me
There was an unexpected error (type=Not Found, status=404). No message available
and I have no idea what I should do to repair it. Maybe I should change something in my pom.xml
??
My pom.xml looks like

It is generated automatically, I write only one dependency
<dependency>
<groupId>com.h2database</groupId><artifactId>h2</artifactId>
</dependency>
Use basePackages:
@ComponentScan(basePackages = { "com.person","com.controller"} )
