Spring data r2dbc: Problem connecting with mysql - 'r2dbcEntityTemplate' could not be found - spring-boot

My spring boot application is trying to connect to a mysql 5.7 with spring data r2dbc. The setup appears to be pretty straight-forward. However, I kept encountering unexpected exception.
Any help would be appreciated.

It turns out to be a Spring boot issue. Please refer to the below git issue for the resolution

Notes
Notice that the error says that there is not active profile, so it will select the default, despite that the application.yml is setting an active profile to production.
Also notice that the Bean greet is created, which means that the start-class attribute is correctly configured. I am a bit lost in what is missed, I have make it work using java but not Kotlin any suggestion?
Thanks to Oleg Zhurakousky's answer, I took my time to create samples project and document it at github. In the samples, you will find even how I push the code to AWS Lambda.
The error is that I was using the deprecated SpringBootStreamHandler instead the new FunctionInvoker.

Flyway configuration without datasource

Try to setup Flyway v6.0.8 with Spring Boot v2.2.1.RELEASE in application.yaml file:
spring:
# CockroachDB connection
r2dbc:
url: r2dbc:postgresql://localhost:26257/defaultdb
username: test_user
password: qwerty
schema: some_schema
flyway:
# Doesn't support r2dbc driver, and don't think it's really necessary just for database structuring(will be no actual data migrations)
url: jdbc:postgresql://localhost:26257/defaultdb
# schemas: some_schema
user: test_user
password: qwerty
I want to configure Flyway just using spring.flyway.url/user/password without defining any spring.datasource in addition. As I understand that's possible to do based on this merged PR but I still have faced with the following exception regarding not defined datasource:
Caused by: Error creating bean with name 'flyway' defined in class path resource [org/springframework/boot/autoconfigure/flyway/FlywayAutoConfiguration$FlywayConfiguration.class]: Unsatisfied dependency expressed through method 'flyway' parameter 1; nested exception org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'spring.datasource-org.springframework.boot.autoconfigure.jdbc.DataSourceProperties': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.boot.autoconfigure.jdbc.DataSourceProperties]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: org/springframework/jdbc/datasource/embedded/EmbeddedDatabaseType

Connect to Azure KeyVault using K8s ConfigMap and Spring Boot

I have a configmap created in my AKS with these properties
config-application-dev.properties: |
server.port=5001
server.compression.enabled=true
azure.keyvault.uri=<URL>
azure.keyvault.client-id=<CLIENTID>
azure.keyvault.client-key=<CLIENTKEY>
My Spring boot application read those properties using #PropertySource
#PropertySource({ "${propertiesDir}/${envTarget}/config/config-application-${envTarget}.properties" })
public class Application{
...
}
And I want to read the Key using #Value property
#Value("${azure-key-vault-secret}")
private String mySecretProperty;
But, when SpringBoot starts, It throws this error message ...
It can't resolve the placeholder ...
the connection to azure is not working ?

Run Spring Boot Application With Dev Configuration Or Test Configuration

I have some multi-environment configurations.
The application.yml is like
spring:
profiles:
active: #profileActive#
The application-dev.yml is like
server:
port: 8085
spring:
application:
name: xxxx-info
datasource:
name: xxx-db
type: com.alibaba.druid.pool.DruidDataSource
url: jdbc:mysql://192.168.1.14:3306/xxx
username: root
password: *******
driver-class-name: com.mysql.jdbc.Driver
minIdle: 1
maxActive: 8
initialSize : 1
testWhileIdle: true
mybatis:
typeAliasesPackage: com.xxx.commons.common.entity
mapperLocations: classpath:mybatis/*.xml
And the application-test.yml is the same as application-dev.yml.
Application.java is like
#EnableDiscoveryClient
#SpringBootApplication
#EnableEurekaClient
#EnableFeignClients
#MapperScan("com.xxx.ggg.client.dao")
public class ClientInfoApplication {
private static final Logger LOGGER = LoggerFactory.getLogger(ClientInfoApplication.class);
public static void main(String[] args) {
SpringApplication.run(ClientInfoApplication.class, args);
}
}
Then I run spring boot application in IntelliJ
Here is the problem. Running spring boot application with application-test.yml is successful but not with application-dev.yml.
The logs are like

I am not sure how to resolve this error . Can nybody suggest what is going wrong here and why am i getting nullPointerException.
Help is appreciated .
Thanks
This is caused by non-matching Spring Boot dependencies. Check your classpath to find the offending resources. You have explicitly included version 1.1.8.RELEASE, but you have also included 3 other projects. Those likely contain different Spring Boot versions, leading to this error.
I know this is quite an old one, but I faced similar issue and resolved it in a different way. The actuator-autoconfigure pom somehow was invalid and so it was throwing IllegalStateException. I removed the actuator* dependencies from my maven repo and did a Maven update in eclipse, which then downloaded the correct/valid dependencies and resolved my issue.
In my case I had created a SB app from the SB Initializer and had included a fair number of deps in it to other things. I went in and commented out the refs to them in the build.gradle file and so was left with:
implementation 'org.springframework.boot:spring-boot-starter-hateoas'
compileOnly 'org.projectlombok:lombok'
developmentOnly 'org.springframework.boot:spring-boot-devtools'
runtimeOnly 'org.hsqldb:hsqldb'
runtimeOnly 'org.postgresql:postgresql'
annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor'
annotationProcessor 'org.projectlombok:lombok'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
testImplementation 'org.springframework.restdocs:spring-restdocs-mockmvc'
as deps. Then my bare-bones SB app was able to build and get running successfully. As I go to try to do things that may need those commented-out libs I will add them back and see what breaks.
This error is because of multiple projects having the offending resources.
Try out adding the dependencies projects another way around. (like in pom.xml or external dependencies)
I had the same its because of hibernate-core version issue when you remove the version so it resolve the problem you should try it.
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>4.1.4.Final</version>
</dependency>
If it's a new project, make sure you remembered to add spring starter web dependency
I had the same its because of version incompatibility check for version or remove version if using spring boot
