Exception during context initialization -

Question

I'm trying to create a simple online store with spring. But the error that occurred is above my skills. I googled all I could, and I'm helpless. Since last time everything worked I created a new controller, few services and a thymeleaf template. I can post the whole project on github if anyone would be willing to check it. Posting error log below

Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.

True, it's a nullpointer. But except the main method, the stacktrace is only pointing to some inner methods of spring. I got completely no idea what to do with it :-(. Just blindly digging through the code and praying — karjan, Jul 02 '17 at 17:40

I had the same problem. After adding Thymeleaf framework support to my Spring Boot project using Intellij, the IDE added Thymeleaf dependencies that were conflicting with the Spring Boot ones. Just removing them from the Project Structure->Libraries fixed the problem.

It seems like a somehow version mismatch occurred between your thymeleaf version and your spring boot version. Place a break point at ThymeleafAutoConfiguration class at line 143. Most probably you will see that the value of the 'setCheckExistence' is null, meaning that thymeleaf's class SpringResourceTemplateResolver of this version does not contain the method 'setCheckExistence' (or it has a different signature from what the spring boot is expecting).

Yes, you're right it's null. Any idea why it happened and how to fix it? – karjan Jul 02 '17 at 18:04
After your post, I tried to change versions of spring and thymeleaf dependencies in maven. After declaring versions as newest releases. New error appeared. "can't resolve method cors()". In securityConfiguration class. – karjan Jul 02 '17 at 19:06
Try this: https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-thymeleaf/1.5.4.RELEASE – Alexander Jul 03 '17 at 05:38
Yes, I tried that yesterday. That's when the new error "can't resolve method cors()" appeared. – karjan Jul 03 '17 at 10:02

Ok, it took me a day but it's working. It appeared that maven was using extra dependencies, project used 2 versions of few libraries. Deleting all maven repositories from my drive did not help. After pushing the project to github, removing everything from my pc, and downloading the project. Everything went back to normal. Thank you @Alexander for help

I have the same issue. I fix it by removing the /.m2 folder and reloading all projects maven dependencies.
