Data is not getting inserted in Spring boot + Spring data JPA? - spring

Question

I have made a spring boot application, in the application I am spring-data-jpa. The problem is there while inserting the data in database, it shows the data is been inserted but there is no data in database. Following is my code. Please let me know where I am doing mistake. Thanks in advance.

Answer 1

If the H2 database is found on your classpath, Spring Boot will automatically set up an in memory H2 database for your use. Just remove H2 dependency from your gradle!

Answer 2

Change compile("com.h2database:h2") to test("com.h2database:h2") and it will do the trick (you most likely would like to have H2 for your future tests).
Also, some suggestions for you:
annotation #Bean above the public String saveProduct(/*#RequestBody User user*/) method is not needed;
annotation #Component above the public class User extends BasePOJO class is not needed;
if you move class public class AVS to the base package of the project
(package avs;) you can get rid of both annotations:
#EntityScan(basePackages = {"avs.pojo"})
#EnableJpaRepositories(basePackages = {"avs.repository"})
The problem with current implementation is, that if you add a Service class to avs.service package, it won't be picked up by spring and you will be forced to configure #ComponentScan, which is kind of an option, but #SpringBootApplication does it automatically, if it's in a right place.
