Sprint Boot Data JPA: Keine qualifizierende Bean vom Typ 'java.util.Set <javax.persistence.EntityManager>' verfügbar

Question

Ich kann nicht mit spring-boot-starter-data-jpa beginnen. Ich habe eine einfache Spring Boot App nach this guide erstellt, aber mit Hibernate und verwandten Konfig.

build.gradle:

dependencies { 
    // Spring stuff 
    compile 'org.springframework.boot:spring-boot-starter-data-jpa:1.5.1.RELEASE' 
    compile 'org.springframework.data:spring-data-jpa' 
    compile 'org.springframework:spring-webmvc' 
    // Jackson 
    compile 'com.fasterxml.jackson.core:jackson-databind:+' 
    compile 'com.fasterxml.jackson.dataformat:jackson-dataformat-yaml:+' 
    // Postgres 
    compile 'org.postgresql:postgresql:+' 
    // Hibernate 
    compile 'org.hibernate:hibernate-core:5.2.8.Final' 
} 

Jedes Mal, wenn ich versuche, die App zu laufen, habe ich am Ende mit dem Follow-up:

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

Ich habe this bug gesehen (die angeblich als der festgelegt ist 1.10.7) aber Downgrade spring-data-jpa zu 1.9.x hat nicht geholfen, ich habe immer noch den gleichen Fehler.

Irgendwelche Ideen?

Answer 1

Das Problem ist in hibernate-core. Das Entfernen aus Abhängigkeiten behebt das Problem.
