Problem: When doing a Post req Via POSTMAN to http://localhost:8080/courses/ just after adding validator field.

On doing the first run in Validation video, doing the following : POST - http://localhost:8080/courses/

via POSTMAN, produced following :

{
  "timestamp": 1491542770698,
  "status": 500,
  "error": "Internal Server Error",
  "exception": "org.springframework.beans.factory.NoUniqueBeanDefinitionException",
  "message": "No qualifying bean of type 'org.springframework.validation.Validator' available: expected single matching bean but found 2: jsr303Validator,mvcValidator",
  "path": "/api/v1/courses/"
}

and the following on the Intellij Idea

threw exception [Request processing failed; nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'org.springframework.validation.Validator' available: expected single matching bean but found 2: jsr303Validator,mvcValidator] with root cause

org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'org.springframework.validation.Validator' available: expected single matching bean but found 2: jsr303Validator,mvcValidator.

Found the Answer on Stackoverflow, This is the link link

just need to add the following in the RestConfig,

@Bean
public javax.validation.Validator localValidatorFactoryBean() {
   return new LocalValidatorFactoryBean();
}

this how my RestConfig Looks Now

package com.teamtreehouse.core;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Lazy;
import org.springframework.data.rest.core.annotation.RestResource;
import org.springframework.data.rest.core.event.ValidatingRepositoryEventListener;
import org.springframework.data.rest.webmvc.config.RepositoryRestConfigurerAdapter;
import org.springframework.validation.Validator;
import org.springframework.validation.beanvalidation.LocalValidatorFactoryBean;

@Configuration
public class RestConfig extends RepositoryRestConfigurerAdapter {
  @Autowired
  @Lazy
  private Validator validator;

  @Override
  public void configureValidatingRepositoryEventListener(
      ValidatingRepositoryEventListener validatingListener) {
    validatingListener.addValidator("beforeCreate",validator);
    validatingListener.addValidator("beforeSave",validator);

  }

  @Bean
  public javax.validation.Validator localValidatorFactoryBean() {
    return new LocalValidatorFactoryBean();
  }
}
