trying to implements JPA on a springboot sample but got that error:

似乎我缺少了一些罐子..但不知道是哪个罐子...有任何猜想吗?

It seems that I'm missing some jars.. but don't know which ones... Any guess?

这是我的build.gradle

Here is my build.gradle

apply plugin: 'java'
apply plugin : 'idea'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
apply plugin: 'war'

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    mavenCentral()
}

configurations {
    providedRuntime
}

dependencies {
    compile('org.springframework.boot:spring-boot-starter-web')
    providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    compile('org.apache.tomcat.embed:tomcat-embed-jasper')
    compile group: 'org.hibernate.javax.persistence', name: 'hibernate-jpa-2.0-api', version: '1.0.1.Final'
    compile group: 'org.hibernate', name: 'hibernate-core', version: '4.2.17.Final'
    compile group: 'org.springframework.data', name: 'spring-data-jpa', version: '2.0.6.RELEASE'
}

或者也许我想念其他东西...?

Or maybe I'm missing something else...?

推荐答案

javax.persistence.PersistenceContext.synchronization().您的项目取决于 org.hibernate.javax.persistence:hibernate-jpa-2.0-api . spring-data-jpa 已经依赖于另一个JPA规范jar(很可能是JPA 2.1规范)，因此我想这就是问题所在.它不缺少罐子，罐子太多了.

javax.persistence.PersistenceContext.synchronization() was introduced in JPA 2.1. Your project depends on org.hibernate.javax.persistence:hibernate-jpa-2.0-api. spring-data-jpa already depends on another JPA spec jar (which is most likely a JPA 2.1 spec), so I would guess that's where the issue's coming from. It's not missing jars, it's too many of them.

顺便说一句， spring-data-jpa:2.0.6.RELEASE 应该与 hibernate-core:5.2.16.Final 一起使用.有什么理由让您觉得您需要Hibernate 4?

By the way, spring-data-jpa:2.0.6.RELEASE is meant to be used with hibernate-core:5.2.16.Final. Is there any reason why you feel you need Hibernate 4?
