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
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.
