Spring boot + Kotlin + MongoDb: Cannot resolve reference to bean 'mongoTemplate' while setting bean property

I am trying to make a simple application using kotlin and spring boot which connects to mongodb and makes some operations there, however I am facing this issues.
If you guys want to see more details, here is the link of the project on git
https://github.com/lucassklp/spring-boot-with-kotlin-example
Anyway I'll add the code here to make it simple:

a friend told me that it is a problem with kotlin reflection (see the very last lines of exception).
Check it out:
https://kotlinlang.org/docs/reference/reflection.html
My problem was solved by adding this dependency in my pom.xml
<dependency>
<groupId>org.jetbrains.kotlin</groupId>
<artifactId>kotlin-reflect</artifactId>
</dependency>
Thank you all!

I had the same problem and it was solved by adding these lines to my build.gradle:
dependencies {
// ...
implementation "org.jetbrains.kotlin:kotlin-reflect:1.6.21"
}

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

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.

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.

The Spring application seams to have an error

I am new to spring and for a project in school that I need to finish next week I must create a part of a Product Registration System. So I need to create the login, then a form to add a new product for one type of user (applicant) and then a search page and product page for another type of user (Regulator).
I found a tuto on this site :
https://o7planning.org/fr/11705/creer-une-application-de-connexion-avec-spring-boot-spring-security-jpa#a13933643
I followed it but I didn't want to use the security part because I don't really need it.
So I did almost everything I need to start, and after that I was going to create the actual pages with CSS and all, the second form etc..
Ting is it doesn't work..

Thank you in advance :)

The error says:
Cannot load driver class: com.mysql.jdbc.Driver
Your data source is:
spring.datasource.url=jdbc:mysql://localhost:3306/techno_web?useSSL=false
spring.datasource.username=username
spring.datasource.password=password
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
But you have
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<scope>runtime</scope>
</dependency>
Remove these and add the MySQL JDBC Driver
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>

java.lang.IllegalStateException: Cannot load driver class:
com.mysql.jdbc.Driver
The error is thronw because you load in pom.xml two dependencies for pôstgres and sql server which are usless ;
so add the mysql dependency and remove other jdbc drivers dependency (useless )
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>

As this is no question i just suggest the following:
You wrote, that you dont care about the security stiff, so why you kept the WebSecurityConfig?
As you seem to be not far from the beginning, just drop the whole thing and start over. Everything you wanna do is expressed in this tutorial -> http://www.vogella.com/tutorials/SpringBoot/article.html
I've completed it a few days ago. Have fun and good luck #school.

Spring Boot 2 - Unsatisfied dependency on Feign client when autowired for service

I have a pretty simple situation and I've tried a few things now and I can't find the cause of this issue. It claims it can not Autowire the Feign client class though this is how I have done this in Spring Boot 1.5.9. At least I'm pretty sure. Things work fine in all my unit tests though I'm mocking this client. Formerly it was a part of an imported library however to eliminate possibilities of me not properly locating the bean I just added it to the same project.
I'm not the most experienced with Spring or Feign so I'm wondering if it's obvious what I'm missing here.
Simple feign client:
#FeignClient(name = "my-other-service")
public interface OtherServiceClient {
#GetMapping(value = "/foo/{fooId}")
#ResponseBody
String getFoo(#PathVariable int fooId);
}
Main application class:
#SpringBootApplication
#EnableDiscoveryClient
#EnableFeignClients
// Had a component scan here when in other module
public class MyServiceApplication {
public static void main(String[] args) {
SpringApplication.run(MyServiceApplication.class, args);
}
}
The service that depends on the feign client:
#Service
public class FooService {
private final FooRepository fooRepository;
private final BarRepository barRepository;
private OtherServiceClient otherServiceClient;
#Autowired
public OrderService(
FooRepository fooRepository,
BarRepository barRepository,
OtherServiceClient otherServiceClient) {
this.fooRepository= fooRepository;
this.barRepository = barRepository;
this.otherServiceClient = otherServiceClient;
}
Since it might be an auto config thing here is the configuration report:

I'm pretty stumped at this point.
EDIT:
Update, so, in order to investigate more as I was confident the service started prior to beginning the Feign work I commented out all references to the feign client and the feign client itself except the the configuration annotations on the application class. I still see the reference to the database driver on start up but the application does indeed run. This is the exception I see on start up but without Feign interactions the application starts.

The database driver is on the older side so I might see about updating it to the ojdbc8 driver maybe while I'm at it...

There was an issue in feign client before. I guess you are experiencing the same maybe because you are using an old version but what you should do is including the pathVariable name in your #PathVariable annotation like this
#RequestMapping(value = "/hello/{name}", method = RequestMethod.GET)
String hello(#PathVariable(value = "name") String name);
You can find the details from here

When you using rest feign client service we need to define exact #Pathvariable name.
#GetMapping("/hello-world/from/{from}/to/{to}")
public String getHelloWorld(#PathVariable("from") String from, #PathVariable ("to") String to);

I had the same issue with #pathvariable, its resolved when I added the value property of #PathVariable like below,
#PathVariable(value = "from") String from,
#PathVariable(value = "to") String to);

#GetMapping(value = "/foo/{fooId}")
#ResponseBody
String getFoo(#PathVariable(value="fooId") int fooId);
will do
