Sprint引导数据JPA：没有类型为'java.util.Set< javax.persistence.EntityManager>'的合格bean可得到 [英] Sprint Boot Data JPA: No qualifying bean of type 'java.util.Set<javax.persistence.EntityManager>' available

问题描述

我无法开始使用 spring-boot-starter-data-jpa 。我已经按照本指南创建了一个简单的Spring Boot应用程序，但是Hibernate和相关的配置。
$ b

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'c​​om.fasterxml.jackson.core：jackson-databind： +'
 compile'c​​om.fasterxml.jackson.dataformat：jackson-dataformat-yaml：+'
 // Postgres 
 compile'org.postgresql：postgresql：+'
 / / Hibernate 
 compile'org.hibernate：hibernate-core：5.2.8.Final'
} 
  

无论何时我尝试运行该应用程序，我都会得到以下结果：

 启动应用程序时出错语境。要显示自动配置报告，请启用'debug'重新运行您的应用程序。

我曾见过此错误（据报道固定为1.10.7），但将> spring-data-jpa 降级为 1.9.x 没有帮助，但我仍然遇到同样的错误。

有什么想法？

解决方案

问题出在冬眠核。从依赖关系中删除它可以解决问题。

I am unable to get started with spring-boot-starter-data-jpa. I've created a simple Spring Boot app following this guide, but with Hibernate and related config.

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'
}

Whenever I try to run the app, I end up with the following:

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

I have seen this bug (which is reportedly fixed as of 1.10.7) but downgrading spring-data-jpa to 1.9.x didn't help, I still got the same error.

Any ideas?

解决方案

The problem is in hibernate-core. Removing it from dependencies resolves the issue.
