I am following the spring boot project book.

The error in my code is:

Should Spring Boot Data JPA automatically create EntityManagerFactory bean?

Should Spring Boot Data JPA automatically create EntityManagerFactory bean?
I have added a table using Liquibase called Fred to my code, and now I wish to add JPA support for this.
Upon adding:
public interface FredRepository extends JpaRepository<Fred, Long> {
}
I get
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'entityManagerFactory' available
I understood that this bean should be created by spring. Can anyone explain when spring creates this bean for me? If it doesn't, why not?

application.yml
spring:
application:
name: xxx
datasource:
driver-class-name: org.postgresql.Driver
url: jdbc:postgresql://postgres:5432/xxx
username: xxx
password: xxx
jpa:
hibernate:
ddl-auto: validate
liquibase:
change-log: db/changelog/changelog.xml

In the properties file you provide, datasource is configured for Postgres, but according to pom file, H2 should be configured during tests (the Postgres driver and url should be in src/main/resources/application.yaml only).
Maybe, you just need to override datasource properties in test resources (src/test/resources/application.yaml):
spring:
datasource:
driver-class-name=org.h2.Driver
url=jdbc:h2:mem:sample;DB_CLOSE_DELAY=-1
username=sa
password=password
Side note
Keycloak adapters for Spring are very deprecated. Do not use it.
See those tutorials for alternatives to configure resource-servers.
For consuming admin API, just use one of Spring REST clients (#FeignClient, RestTemplate or WebClient)

It turns out I was missing the hibernate jars in my pom.
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>${hibernate.version}</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>${hibernate.version}</version>
</dependency>
Also worth pointing out that hibernate 6 requires spring boot 3 and doesn't work with spring boot 2.

Springboot autoconfiguration #ConditionalOnClass TypeNotPresentExceptionProxy

Trying to learn Springboot Autoconfiguration.
I created the folowing module with an autoconfiguration class, the idea as indicated is that the bean migrationAutoConfigBeanCreated will be created if the caller app have Flyway library in the claspath:
#Slf4j
#ConditionalOnClass(Flyway.class)
public class MigrationAutoConfiguration {
#Bean
public void migrationAutoConfigBeanCreated(){
log.debug("MigrationAutoConfiguration is called");
}
}
And it work fine, when the caller module have the Flyway library in it's classpath, the debug log is shown.
The problem is when I try to apply the #ConditionalOnClass only to the bean instead the entire Configuration class, like this:
#Slf4j
public class MigrationAutoConfiguration {
#Bean
#ConditionalOnClass(Flyway.class)
public void migrationAutoConfigBeanCreated(){
log.debug("MigrationAutoConfiguration is called");
}
}
I have this error on lunch:

the new interface
public interface Encoreable {
void performEncore();
}
new implement

you can try change the value of the #DeclareParents from com.lyman.example.demo.concert.Performance+ to
com.lyman.example.demo.concert.Performance

Solution 1:
com.lyman.example.demo.concert.Performance+
to
com.lyman.example.demo.concert.PerformanceImpl
Solution 2:
ReflectionWorldException: warning can't determine implemented interfaces of missing type org.springframework.boot.autoconfigure.http.codec.CodecsAutoConfiguration
Delete your Codecs dependency in build.gradle or pom.xml.
OR
#SpringBootApplication(exclude = CodecsAutoConfiguration)
It worked for me, but I don't know why

Its a simple spring boot app with rest controller.
Calling http://localhost:8084/springboot_test/ loads the default index.html page
The problem is when I call http://localhost:8084/springboot_test/home it is not printing the output System.out.println("###Home Controller Called"); so I guess the request is not called on rest controller itself. But why it isn't called?
Update
Using the #ComponentScan("com.rsc.springboot_test") on rest Controller as suggested by #javaguy works but I want to apply the #componentScan on top of main class so that it scans all packages on startup.
Trying the following gives error:
#SpringBootApplication
#ComponentScan(basePackages = { "com.rsc.*" })
public class SpringBootTest {
public static void main(String[] args) {
SpringApplication.run(SpringBootTest.class, args);
}
}

Your RestController is NOT detected by the Spring container, so you need to add the package details to ComponentScan, so change the main as below:
#SpringBootApplication
#ComponentScan(basePackages = { "com.rsc" })
public class SpringBootTest {
public static void main(String[] args) {
SpringApplication.run(SpringBootTest.class, args);
}
}
Also, for your test application, you don't need any xml (as we are using annotations and scanning the components using componentscan), seems like you have configured one at the below path:
C:\Users\Documents\AppData\Roaming\NetBeans\8.2\apache-tomcat-8.0.27.0_base\conf\Catalina\localhost\springboot_test.xml
You need to delete and restart the server.

#SpringBootApplication by default triggers component scanning on the same package as annotated class and all subpackages.
In your case, since main class is in com.rsc.springboot_test and controller in com.rsc.springboot_test_controller, TestController class will not be scanned.
There are two approaches to solve it:
recommended: move TestController to another package so that it matches default classpath scanning, for example to com.rsc.springboot_test.controller
modify #SpringBootApplication to scan other packages:
#SpringBootApplication(scanBasePackages = {
"com.rsc.springboot_test",
"com.rsc.springboot_test_controller"
})

Your problem is, that your Application class is under ComponentScan. Your project structure should be:
src
main
java
com.company
Application.java
controller
MyController.java
service
repository
And your Application:
#SpringBootApplication
#ComponentScan(basePackages = {
"com.rsc.springboot_test_controller",
"com.rsc.springboot_test_service",
//etc... no ' at the end of the last package
})
public class SpringBootTest {
public static void main(String[] args) {
SpringApplication.run(SpringBootTest.class, args);
}
}
Actually the above is the mixture of two different approaches but will work. Remember, that your Application.java should be in the root package for all other packages.
And reading your question once again, I would recommend to change the Controller:
package com.rsc.springboot_test_controller;
#RestController
public class testController {
#RequestMapping("/home")
public String home() {
return "###Home Controller Called";
}
}
