Question

我试图抓住弹簧数据审核。所以我从一个简单的build.gragle开始，我在下面写道。但我无法获得javax.persistence的所有类。*我的意思是@Entity超过任何POJO给我无法解析符号而且没有可用的导入。我无法弄清楚我是什么在我的gradle文件中丢失。

buildscript {
    ext {
        springBootVersion = '1.5.2.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'


jar {
    baseName = 'auditTest'
    version =  '1.0.0-SNAPSHOT'
}

repositories {
    mavenCentral()
    mavenLocal()
}
group = 'com.shubham'
version = '1.0.0-SNAPSHOT'

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework.data:spring-data-jpa:1.11.1.RELEASE')
}

但后来我从Spring's Getting Started with JPA页面复制了gradle文件。 javax.persistance的所有课程都可用。

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.5.2.RELEASE")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'

jar {
    baseName = 'Audit'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
    maven { url "https://repository.jboss.org/nexus/content/repositories/releases" }
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    compile("org.springframework.boot:spring-boot-starter-data-jpa")
    testCompile("org.springframework.boot:spring-boot-starter-test")
}

那么我在build.gradle文件中遗漏了什么？

我看到org.hibernate.javax.persistence:hibernate-jpa-2.1-api（javax.persistence。*所在的位置）不依赖于org.springframework.data:spring-data-jpa。相反，它取决于org.hibernate:hibernate-core和org.hibernate:hibernate-entitymanager。

因此，您还应该编译这些包，或者使用org.springframework.boot:spring-boot-starter-data-jpa。

javax.persistance.Entity没有导入？
