无法解析 Springboot Gradle 项目中的 @Entity 和 javax.persistence.Entity

Question

我按照https://spring.io/guides/gs/accessing-data-mysql/上的指南开始使用 MySQL for Gradle 项目，但是，当我尝试添加 @Entity 注释时

这是我的 build.gradle，它遵循网站上的相同内容：

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:2.0.5.RELEASE")
    }
}

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

bootJar {
    baseName = 'gs-accessing-data-mysql'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")

    // JPA Data (We are going to use Repositories, Entities, Hibernate, etc...)
    compile 'org.springframework.boot:spring-boot-starter-data-jpa'
    compile group: 'javax.persistence', name: 'persistence-api', version: '1.0'

    // Use MySQL Connector-J
    compile 'mysql:mysql-connector-java'

    testCompile('org.springframework.boot:spring-boot-starter-test')
}

Answer 1

正如您在 SpringBoot 的依赖树中看到的，javax.persistence已经包含在 中spring-boot-starter-data-jpa，但它不是1.0.

消除：

compile group: 'javax.persistence', name: 'persistence-api', version: '1.0'
