I'm trying to connect embedded mongodb and test it with MongoDbSpringIntegrationTest. The problem is that the identical code works with spring boot in 2.7.7 but doesn't work with spring boot in 3.0.0. The question is how can I enable embedded mongodb for spring boot tests in 3.0.0?

When I run this I get this error:

Spring Boot 3 support has been added to flapdoodle as described in this issue and i found answer on my question in issues.

I had database connection issues on my Java project because of mysql's replacement with mariadb on Debian 10. I am using HikariCP to connect, I updated the code so that it works with mariadb :
HikariConfig hikariConfig = new HikariConfig();
hikariConfig.setMaximumPoolSize(10);
hikariConfig.setDriverClassName("org.mariadb.jdbc.Driver"); // added after internet research about hikaricp and mariadb
hikariConfig.setJdbcUrl("jdbc:mariadb://localhost:3306/" + db);
hikariConfig.setUsername(user);
hikariConfig.setPassword(pass);
I upgraded my HikariCP setup : I replaced 2.7.8 with 3.4.5 (even though I don't know what's the difference) and added the mysql-connector dependency after viewing this post (btw there is no version for this guy's mysql-connector in his pom.xml but I had to put one so I chosed 6.0.6) and I am still getting a Java error :
java.lang.RuntimeException: Failed to load driver class org.mariadb.jdbc.Driver in either of HikariConfig class loader or Thread context classloader
at com.zaxxer.hikari.HikariConfig.setDriverClassName(HikariConfig.java:486)

You are using mariadb now, not mysql. Change
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
<version>6.0.6</version>
</dependency>
to
<dependency>

I'm working on Spring Cloud project using Java 11 and Maven.
I've try to register an Eureka client service with an Eureka Server. But there is no registered service showing on the Eureka dashboard.
I've been tried to search solution on the internet including Stackoverflow as well but there is no luck.
Here is my dependencies of pom.xml in Eureka Project,

And this is my properties of Eureka Project,

And Here is my one of properties from Client Service (auth-server),

together with AuthServerApplication.java file,
#EnableDiscoveryClient
#SpringBootApplication
public class AuthServerApplication {
public static void main(String[] args) {
SpringApplication.run(AuthServerApplication.class, args);
}
}
I have changed the version and it has started working for me.
<spring-cloud.version>2020.0.3</spring-cloud.version>

spring.datasource.tomcat.connection-properties=useUnicode=true;characterEncoding=utf-8;
spring.datasource.sql-script-encoding=UTF-8
The address of the database is correct and working - 100%
Can someone show another method, more correct for database initialization in the spring?
Do not use this since it has been DEPRECATED!
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
Use this instead
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.username=root
If you change your properties file with the following lines it should work:
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.username=root
This driver class is fine for mysql and you need to use spring.datasource.username= instead of spring.datasource.name=
I hope this helps you
I have spring boot application and i am using vertx.
I want to monitor the services and the jvm and for that i chose Prometheus.
This is my MonitoringConfig class:
#Configuration
public class MonitoringConfig {
#Bean
SpringBootMetricsCollector springBootMetricsCollector(Collection<PublicMetrics> publicMetrics) {
SpringBootMetricsCollector springBootMetricsCollector = new SpringBootMetricsCollector(publicMetrics);
springBootMetricsCollector.register();
return springBootMetricsCollector;
}
#Bean
public ServletRegistrationBean servletRegistrationBean() {
DefaultExports.initialize();
return new ServletRegistrationBean(new MetricsServlet(), "/prometheus");
}
}
And this are my dependencies:
<dependency>

It shows no error in the app, but when i am trying to access http://localhost:8787/prometheus i am getting Not Found.
Also i have tried only with actuator and it still the same.
http://localhost:8787/actuator, http://localhost:8787/health and etc. Allways getting: Not found.
So my question is what can cause this and how can i fix this problem?
I think that some of the dependencies is causing the problem. Try removing one by one and you can notice where is the problem.
Also for monitoring vert.x application here is a good example that can be useful for you.
About the jvm metrics, add this in your start:
DefaultExports.initialize();
new DropwizardExports(SharedMetricRegistries.getOrCreate("vertx")).register();
