Consider defining a bean of type in your configuration in spring boot when using Spring JpaRepository

Question

Good day,

I am doing a Spring Boot Application in my Eclipse IDE. When I right click on my SpringBoot Application file and run as Java application, I hitting error as follow:

---

APPLICATION FAILED TO START

---

Description:

Field tutorialRepository in com.utility.tool.ToolApplication required a bean of type 'com.utility.tool.repository.TutorialRepository' that could not be found.

The injection point has the following annotations:
        - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'com.utility.tool.repository.TutorialRepository' in your configuration.

Then I found that I forget to include the spring boot starter data jar. Hence, I add the following code in my build.gradle and it finally run correctly:

implementation 'org.springframework.boot:spring-boot-starter-data-jpa:2.7.5'

Then I right click my project and export jar as runnable jar, and then try to run it by java -jar my.jar, and it hit back the error.

I open the jar in JdGui, and found that the spring-boot-starter-data-jpa-2.7.5.jar is inside. May I know what is my mistake? My jar structure is something as follow:

The jar is in the list but is at bottom, thus not in my screen shot.

Check your SpringBoot annotations. You may be missing some @Service, @Repository, @Component annotations.
