Sprint引导数据JPA：没有可用的类型为'java.util.Set <javax.persistence.EntityManager>'的合格bean

我无法入门spring-boot-starter-data-jpa。我在this guide之后创建了一个简单的Spring Boot应用程序，但使用Hibernate和相关的配置。Sprint引导数据JPA：没有可用的类型为'java.util.Set <javax.persistence.EntityManager>'的合格bean

的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' 
}

每当我尝试运行应用程序，我结束了以下内容：

我见过this bug（这是据报道，作为固定的1.10.7），但降级spring-data-jpa为1.9.x没有帮助，我仍然有同样的错误。

任何想法？

如果你使用'org.springframework.boot：spring-boot-starter-data-jpa：1.5.1.RELEASE'，你不需要编译'org.springframework.data:spring-data-jpa'，并且可以你发布更多的代码，特别是与配置相关的代码。 –

是的，我知道，我已经包含'spring-data-jpa'专门玩它的版本。至于配置，就是这样，一切都在'build.gradle'中。 – yktoo

删除其中一个或删除休眠核心jar后尝试过 –

问题出在hibernate-core。从依赖关系中删除它可以解决问题。
