SpringBoot with H2 database - failing to execute SQL, while strating the application - spring-boot

Question

I am learning spring security with JPA auth againest H2 table. It fails load seed data from data.sql
I tried access the H2 console, but doesn't let me login. Any suggestions appreciated
applicaiton.properties
spring.datasource.url=jdbc:h2:mem:testdb
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=password
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.h2.console.enabled=true
User.java
#Entity
#Table(name = "USER_TABLE")
public class User {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private int id;
#Column(name="USER_NAME")
private String userName;
- - - - - -
- - - - - -
}
data.sql
insert into USER_TABLE (id, USER_NAME, PASSWORD, ACTIVE, ROLES) values
(1, 'einstein', 'einstein', true, 'USER'),
(2, 'newton', 'newton', true, 'USER'),
(3, 'koushik', 'koushik', true, 'USER');
SecurityConfig.java
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
#Autowired
MyUserDetailsService userDetailsService;
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService);
}
............
............
}
MyUserService.java
#Service
public class MyUserDetailsService implements UserDetailsService {
#Autowired
UserRepository userRepository;
#Override
public UserDetails loadUserByUsername(String userName) throws UsernameNotFoundException {
Optional<User> user = userRepository.findByUserName(userName);
user.orElseThrow(() -> new UsernameNotFoundException("Not found: " + userName));
return user.map(MyUserDetails::new).get();
}
}
I get below error, while starting the spring-boot
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSourceScriptDatabaseInitializer' defined in class path resource [org/springframework/boot/autoconfigure/sql/init/DataSourceInitializationConfiguration.class]: Invocation of init method failed; nested exception is org.springframework.jdbc.datasource.init.ScriptStatementFailedException: Failed to execute SQL script statement #1 of URL [file:/C:/resume-portal/target/classes/data.sql]: insert into USER_TABLE (id, USER_NAME, PASSWORD, ACTIVE, ROLES) values (1, 'einstein', 'einstein', true, 'USER'), (2, 'newton', 'newton', true, 'USER'), (3, 'koushik', 'koushik', true, 'USER'); nested exception is org.h2.jdbc.JdbcSQLSyntaxErrorException: Table "USER_TABLE" not found (this database is empty); SQL statement:

Many thanks to the community.

Answer 1

Since your database generates a unique id for you, you do not have to provide any id in the insert statement.
insert into USER_TABLE (USER_NAME, PASSWORD, ACTIVE, ROLES) values
('einstein', 'einstein', true, 'USER'),
('newton', 'newton', true, 'USER'),
('koushik', 'koushik', true, 'USER');
Change your DML to define no id to solve your problem.
Alternatively, you can create instances of your entity with id = null in a command line runner and add them to the repository.
#Component
public class Initializer implements CommandLineRunner {
#Autowired
UserRepository repository;
#Override
public void run(String... args) throws Exception {
//Pseudocode
User user = new User(id=null,name="Albert Einstein" ...)
repository.save(user)
}
}
