Spring Boot - repository field required a bean named 'entityManagerFactory' that could not be found

spring-boot-starter-data-jpa will pull in all the hibernate dependencies you need. Using spring boot release 1.5.1, it will pull in hibernate-core:5.0.11 and hibernate-entitymanager:5.0.11. In addition to being unnecessary, your hibernate dependency versions are mismatched which is what I'm guessing is causing the error.

Try removing these dependencies from your pom.xml.

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>4.1.4.Final</version>
</dependency>
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>5.2.3.Final</version>
</dependency>

Then, you can simply wire the ws messenger on your components with

@Autowired
private SimpMessagingTemplate webSocket;

and send the message with

webSocket.convertAndSend(channel, new String(message.getBody()));

In my case(spring boot fat jar) I just add the following to pom.xml.

    <dependency>
        <groupId>javax.xml.bind</groupId>
