I noticed the package issue when I was using Spring Boot 1.2.5.Release, when i changed it to 1.4.2.Release, i did not faced that issue.
I created a simple spring boot starter project with web, jpa and apache derby on Spring boot 1.5.2,1.5.3 and tried on 2.0.0 also but I am getting error org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tomcatEmbeddedServletContainerFactory' defined in class path resource [org/springframework/boot/autoconfigure/web/EmbeddedServletContainerAutoConfiguration$EmbeddedTomcat.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'serverProperties' defined in class path resource [org/springframework/boot/autoconfigure/web/ServerPropertiesAutoConfiguration.class]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/hibernate/HibernateException
same here. so, do u have the solution?
Hi Want to create , different Projects for Service , Repositories , and controllerI understand for controller if we select Spring Web its enough and for Repositories I select JPA , what is required for service? only web dependency is sufficient?
amazing tutorial, I hope you will have more tutorials about Spring Boot in near future! Well done!
After downloading and adding Topic package from earlier project when I am running it, i am getting error like "Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: javassist/bytecode/ClassFile". I have tried many things but I think in video there is nothing done explicitly. Please help me.
add the following dependency to your pom.xml <dependency> <groupId>com.h2database</groupId> <artifactId>h2</artifactId> </dependency>
I dont see any topic about how to connect to external databases. Am I missing some thing.
You have fast internet and a fast machine :p
Thanks a lot Koushik for all the videos, they are really helpful, the best teacher :)There is something that I noticed. If the RestController class is not inside the same package (or subpackage) as the SpringBootApplication, then the controller is not picked by the MVC and my request to for eg. '/topics' returns me a 'not found'. I guess all RestControllers in the classpath are not picked up by the SpringBootApplication. (A complete classpath scan might not be happening)
I have no idea why, but had the same problem.
I noticed the same too
Looking up the documentation specifies that I can specify the basepackages for the componentscan and things work fine when I do so. I realize it was the default same package + child packages that is being scanned when no basepackages are specified!
