intellij idea - Spring Boot: New Project - UnsatisfiedDependencyException: Error creating bean with name 'methodValidationPostProcessor'

Question

I just created a project using Spring Boot (1.5.2.BUILD-SNAPSHOT) on IntelliJ IDEA 2016.3.4 with Spring Initializr.

When I try to run the project I got an exception due to ApplicationEventMulticaster and methodValidationPostProcessor.

Answer 1

Resolved

For some reason artefact spring-boot-starter-web added a dependency to hibernate-validator, therefore spring was expecting me to configure a validator dependency.

I have remove that dependency adding an exclusion to my pom.xml.

   <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.hibernate</groupId>
                <artifactId>hibernate-validator</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

I have added more dependencies including JPA and It is still working fine.
