Spring Boot 2.2 Multi Module Project auto configuration JPA failed

I have a Spring-Boot multimodule Project.
Main Module is a Vaadin Web-App (at the Moment very simple) and a second Module called Login with Spring Entitys, Repository and Service bean.
In the Login Module I have written Testcode that runs against a H2 Database. Tests are green, Entity was created, repository exists and so on. (Everything fine)
When I try to start the WebApp I allways get the Message
A component required a bean named 'entityManagerFactory' that could not be found.
My Main Applicattion Class
#SpringBootApplication(scanBasePackages = "eu.dwich.btc", exclude = ErrorMvcAutoConfiguration.class)
#Import(BtcBackendLoginConfig.class)
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
Then my Config Class in the module
#SpringBootConfiguration
#EnableAutoConfiguration
#ComponentScan(basePackageClasses = BtcBackendLoginConfig.class)
#EntityScan(basePackageClasses = BtcBackendLoginConfig.class)
#EnableJpaRepositories(basePackageClasses = BtcBackendLoginConfig.class)
public class BtcBackendLoginConfig {
}
and the properties file
database.driver-class-name=org.postgresql.Driver
database.database-url=jdbc:postgresql://localhost:5433/btc_dev
database.database-user=btc_dev
database.database-user-password=xxxxx
# --------------------------------------
# special DB settings
database.hibernater-format-s-q-l=true
database.hibernater-gen-statistics=true
database.hibernate-dialect=org.hibernate.dialect.PostgreSQL9Dialect
# possible: create-drop, none, validate, update, create
database.hibernate-ddl-auto=create-drop
database.create-db-script=true
First (maybe simple) Question, where should I put the application.properties to configure the database, in the web Project or in the Login module?
Second Question what I'm doing wrong? is it not possible to get the spring boot autoconfiguration to work? (I don't whant to configure datasource and entitymanager)
I have tryed a lot of different configrurations nothing worked until now.
Thanks in advance

why does spring exclude the whole spring Data stack??

You use the wrong variable keys so Spring cannot configure the objects required.
Instead, use the following
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5433/btc_dev
spring.datasource.username=btc_dev
spring.datasource.password=xxxxx
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format-sql=true
spring.jpa.properties.hibernate.generate_statistics=true
spring.jpa.database=postgresql
spring.jpa.hibernate.dll-auto=create-drop
Also, make sure you have all the required libraries on the classpath.
You need at least javax.persistence-api and hibernate.
I would also advice you NOT to use basePackageClasses unless you know what it does. If you place your Application configuration in his own package instead of the root, Spring won't be able to find any eligible classes.
At least for now, use basePackages = "eu.dwich.btc" instead.
Here is a list of common Spring properties.
Next to the # DATASOURCE section you see the reference to DataSourceAutoConfiguration.

Check your pom file , you must be missing some dependencies. I was also same problem and resolved after carefully gone through pom file , posgress driver jar was missing and spring-data depenndency was missing. Its giving very generic error you should enable stack trace
"server.error.include-stacktrace=never"
to get more detailed error.

I think I found the error
Spring applikation simple without imports
#SpringBootApplication(scanBasePackages = "eu.dwich.btc", exclude = ErrorMvcAutoConfiguration.class)
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
the backend config needs some modifikation
#Configuration
#EnableTransactionManagement
#EntityScan(basePackages = "eu.dwich.btc")
#EnableJpaRepositories(basePackages = "eu.dwich.btc")
#Import({
DataSourceAutoConfiguration.class,
HibernateJpaAutoConfiguration.class,
DataSourceTransactionManagerAutoConfiguration.class })
#Profile("!test")
public class BtcBackendLoginConfig {
}
the second #SpringBootApplication was an error and is not needet
without the Autoconfig imports it won't work
and be carefull with the properties, tada.....
#spring.jpa.properties.hibernate.ddl-auto=create-drop is wrong
#spring.jpa.hibernate.hbm2ddl.auto=create-drop is also wrong
# the right one (as mentioned by Nico Van Belle) is:
spring.jpa.hibernate.ddl-auto=create-drop
and if your run an real database (not H2) the default ddl-auto= is none
In my opinion the import of the autoconfig classes is not the best way, but it works.

Cannot run spring boot app after adding Jpa maven dependency

I started a spring boot app based on the heroku's sample app, following their tutorial.
I'm running a postgres docker container to which the app can connect correctly. Now I'd like to use Hibernate (following this Baeldung guide but when I add the Jpa dependency :
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
Then I get the following error upon running the app :
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'org.springframework.context.annotation.ConfigurationClassPostProcessor.importRegistry' available
I don't understand this error and can't find much about it (or I don't understand). I was suggested to check the config, although I'm not sure what I would missing.
Here are some of the files in the project :
application.properties
########## Original config (Heroku template)

My IDE (IntelliJ) correctly imports the dependency, and I can use various hibernate annotations on my models, but the issue is when running the app. Any advice is greatly welcome, thanks!

May be you should check the Heroku tutorial again. It says that you have to add a configuration bean to your app! It means that you need at least one class with #Configuration. The configuration bean at the tutorial is as follows:
package com.example.demo;
import com.zaxxer.hikari.*;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.*;
import javax.sql.DataSource;
#Configuration
public class DatabaseConfig {
#Value("${spring.datasource.url}")
private String dbUrl;
#Bean
public DataSource dataSource() {
HikariConfig config = new HikariConfig();
config.setJdbcUrl(dbUrl);
return new HikariDataSource(config);
}
}

#Configuration annotated class is used by JavaConfig as a source of bean definitions. You need to create configuration class and provide method dataSource() inside that to create bean.
#Configuration
public class DatabaseConfig {
#Value("${spring.datasource.url}")
private String dbUrl;
#Bean
public DataSource dataSource() throws SQLException {
if (dbUrl == null || dbUrl.isEmpty()) {
return new HikariDataSource();
} else {
HikariConfig config = new HikariConfig();
config.setJdbcUrl(dbUrl);
return new HikariDataSource(config);
}
}
}
For more information here is link

If you are following the Heroku Getting Started just delete in Main.java file this attributes:
#Value("${spring.datasource.url}")
private String dbUrl;
#Autowired
private DataSource dataSource;
Spring already creates theam.

New Error in spring boot 2.3.0.RELEASE : UnsatisfiedDependencyException for Oracle 12.2.0.1 jdbcdriver but not with mysql jdbcdriver

If I run the above code using spring boot 2.2.7.RELEASE, it works just fine -- No exceptions!!
After 2 days, I thought of configuring a mysql datasource on localhost. The same program runs just fine (with spring boot 2.3.0.RELEASE) but this time it used the mysql datasource.

What is happening with the oracle jdbc driver in spring boot 2.3.0.RELEASE ?
What is mysql jdbc driver doing correctly in spring boot 2.3.0.RELEASE ?
Thank you.

What is happening with the oracle jdbc driver in spring boot 2.3.0.RELEASE ?
The JDBC Driver is doing just fine.
As you already learned in the comments the problem is that
a) Spring Data JDBC now requires a Dialect for each database
b) Spring Data JDBC does not ship with a Dialect for Oracle.
The fix:
As described in Spring Data JDBC Firebird dialect not recognized and in https://spring.io/blog/2020/05/20/migrating-to-spring-data-jdbc-2-0
you need to provide your own Dialect implementation right now.
Something like this should work:
class MyOracleDialect extends AnsiDialect {
private static final LimitClause LIMIT_CLAUSE = new LimitClause() {
#Override
public String getLimit(long limit) {
return String.format("FETCH NEXT %d ROWS ONLY", limit);
}
#Override
public String getOffset(long offset) {
return String.format("OFFSET %d ROWS", offset);
}
#Override
public String getLimitOffset(long limit, long offset) {
return String.format("OFFSET %d ROWS FETCH NEXT %d ROWS ONLY", offset, limit);
}
#Override
public Position getClausePosition() {
return Position.AFTER_ORDER_BY;
}
};
#Override
public LimitClause limit() {
return LIMIT_CLAUSE;
}
}
You then need to make the Dialect available via a DialectProvider as described in the referenced Stackoverflow question:
Some background:
So far the Spring Data team does not run their integration tests with an Oracle database.
This is because for quite some time it was unclear how to do that in a legal way since all the code including the build infrastructure was open source and Oracle required accepting of all kinds of stuff to use a database instance or their driver.
By now Docker images are available for testing and the JDBC driver is available from Maven Central. It is still a little tricky since the current options for docker images that I am aware of let you choose between an image size of many GBs or a start up time of about 15 minutes.
Anyway there is a community member working on the issue: https://jira.spring.io/browse/DATAJDBC-256
I'm therefore confident that we will be able to fully support Oracle in the near future.

This Dialect resolver fixed my issue with Oracle.
#Configuration
public class SpringDataJdbcConfiguration extends AbstractJdbcConfiguration {
#Override
public Dialect jdbcDialect(NamedParameterJdbcOperations operations) {
return AnsiDialect.INSTANCE;
}
}

Currently spring data jdbc doesn't support oracle dialect
You need to define your own dialect resolver
Add following class for Oracle Dialect which implements JdbcDialectProvider.
import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.SQLException;
import java.util.Locale;
import java.util.Optional;
import org.springframework.data.jdbc.repository.config.DialectResolver.JdbcDialectProvider;
import org.springframework.data.relational.core.dialect.AnsiDialect;
import org.springframework.data.relational.core.dialect.Dialect;
import org.springframework.jdbc.core.ConnectionCallback;
import org.springframework.jdbc.core.JdbcOperations;
public class OracleDialectResolver implements JdbcDialectProvider {
#Override
public Optional<Dialect> getDialect(JdbcOperations operations) {
return Optional.ofNullable(operations.execute((ConnectionCallback<Dialect>) OracleDialectResolver::getDialect));
}
private static Dialect getDialect(Connection connection) throws SQLException {
DatabaseMetaData metaData = connection.getMetaData();
String name = metaData.getDatabaseProductName().toLowerCase(Locale.ROOT);
if (name.contains("oracle")) {
return AnsiDialect.INSTANCE;
}
return null;
}
}
Register your provider by putting a file spring.factories in the META-INF folder of your class path and add the following line.
org.springframework.data.jdbc.repository.config.DialectResolver$JdbcDialectProvider=com.mypackage.jdbctemplate.dialect.OracleDialectResolver //fuly qualified class name of your dialect resolver class

I had exactly the same problem last week.
The change I did in my project was simpler: I just replaced HikariCP dependency with tomcat-jdbc in pom.xml:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jdbc</artifactId>
<!-- HikariCP doesn't deals with jdbcDialect properly -->
<exclusions>
<exclusion>
<groupId>com.zaxxer</groupId>
<artifactId>HikariCP</artifactId>
</exclusion>
</exclusions>
<!-- Dependency removed -->
</dependency>
<!-- Dependency to tomcat-jdbc to deal with jdbcDialect -->
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-jdbc</artifactId>
</dependency>
<!--...-->
If I undo this, the exception you posted in title happens again.
Good luck for you.

small update to the already posted answer, for oracle Dialect
in
Build.gradle
implementation group: 'org.springframework.data', name: 'spring-data-relational', version: '2.1.1'
and then create below class
import org.springframework.context.annotation.Configuration;
import org.springframework.data.jdbc.repository.config.AbstractJdbcConfiguration;
import org.springframework.data.relational.core.dialect.OracleDialect;
import org.springframework.data.relational.core.dialect.Dialect;
import org.springframework.jdbc.core.namedparam.NamedParameterJdbcOperations;
#Configuration
public class SpringDataJdbcConfiguration extends AbstractJdbcConfiguration {
#Override
public Dialect jdbcDialect(NamedParameterJdbcOperations operations) {
return OracleDialect.INSTANCE;
}
}

These dependencies worked for me.
<parent>
<groupId>org.springframework.boot</groupId>

Unable to obtain connection from database: FATAL: database "demodb" does not exist
Before, i had an issue, where i got a Fatal error that my Password was wrong. I made it made it go away (not sure if that leaded to this problem) by changing the "pg_hba.conf" from:
# TYPE DATABASE USER ADDRESS METHOD
# IPv4 local connections:
host all all 127.0.0.1/32 md5
# IPv6 local connections:
host all all ::1/128 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
host replication all 127.0.0.1/32 md5
host replication all ::1/128 md5
to:
host all all 0.0.0.0/0 trust
Then i have restarted the server with:
docker restart container-name
OS: Windows 10
my "application.yml" in my springboot application is:
app:
datasource:
jdbc-url: jdbc:postgresql://localhost:5432/demodb
username: postgres
password: password
pool-size: 30
How do i fix this issue?

I have had the same issue, just simply stop the Postgres app if you’ve downloaded it before, then the problem will be solved.

Check if the Postgres database is installed locally on your machine.
If so, then uninstalling it should do the work.
localhost:5432 is captured by your local database and demodb does not exist there.

I believe you have been following Amigos Code Tutorial!!
If so, you are are running postgres on docker, so it would be advised to stop the postgres(locally installed on pc) and restart the spring application.You are connecting to the container right!!

I don't think your modification of "pg_hba.conf" file led to that error.
host all all 0.0.0.0/0 trust
just configured PostgreSQL to accept all incoming connections.
I guess the reason is that your local computer has a PostgreSQL running which takes the port 5432. I suggest changing the port number to another free one, for example, 5433 in the command that mirashgoku posted for you:
docker run --name postgres-spring -e POSTGRES_PASSWORD=password -d -p **5433**:5432
Meanwhile, please change the port number in your "application.yml":
jdbc-url: jdbc:postgresql://localhost:**5433**/demodb

When I just upgrade to Spring Boot 2.2.1, this exception doesn't occur.
After adding the dependency:
<dependency>
<groupId>com.fasterxml.jackson.module</groupId>
<artifactId>jackson-module-jaxb-annotations</artifactId>
</dependency>
it works for 2.2.2.
So my question is, why do I suddenly need to manually add a dependency after this Spring Boot upgrade.

I would look at your dependencies which might use xml as configuration. I am using Spring Boot 2.3.1 and did not need this dependency until I added Liquibase support. Since I was using xml for the Liquibase configuration then I see same error at startup. Once I added this dependency then error went away.

Assuming your application is using / including Liquibase, this occurs because of an erroneous file in liquibase-core which is defining an SPI extension for a Jackson module but not providing the implementation for that module: https://github.com/liquibase/liquibase/issues/1051
The workaround listed in the OP is sufficient, as its providing the implementation to the Jackson module referenced in the SPI file, but you can also upgrade Liquibase to >= 3.10.1 to resolve this (I only tested 3.10.3 but according to the linked defect 3.10.1 should work)
For Gradle, the dependency is:
implementation 'org.liquibase:liquibase-core:3.10.3'
