Question

我正在尝试使用./gradlew构建docker镜像构建docker镜像，但出现以下错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: org/hibernate/boot/registry/classloading/internal/ClassLoaderServiceImpl$Work

当我在本地运行springboot应用程序时，没有出现此错误。效果很好。

这是我的build.gradle：

    buildscript {
    repositories {
        mavenCentral()
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:2.0.4.RELEASE")
        classpath('gradle.plugin.com.palantir.gradle.docker:gradle-docker:0.13.0')
    }
}

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

bootJar {
    baseName = 'gs-rest-service'
    version =  '0.1.0'
}

group = 'hello'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

docker {
    dependsOn build
    name "${project.group}/${bootJar.baseName}"
    files bootJar.archivePath
    buildArgs(['JAR_FILE': "${bootJar.archiveName}"])
}

repositories {
    mavenCentral()
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
    testCompile('org.springframework.boot:spring-boot-starter-test')
    compile 'org.springframework.boot:spring-boot-starter-data-jpa'
    compile 'mysql:mysql-connector-java'
}

我到处搜索，发现了几个问题，通过添加其他依赖项解决了该问题。例如：

    <dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>4.1.4.Final</version>
</dependency>

和

    <dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>5.2.3.Final</version>
</dependency>

或

<dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.3.0</version>
</dependency>

这些解决方案都不适合我，问题仍然存在。

这是我的实体：

    package hello;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class Greeting {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private int id;
    private String content = "";

    public void setContent(String content) {
        this.content = content;
    }

    public void setId(int id) {
        this.id = id;
    }

    public Greeting() {

    }

    public Greeting(int id, String content) {
        this.id = id;
        this.content = content;
    }

    public long getId() {
        return id;
    }

    public String getContent() {
        return content;
    }
}

这是我的application.properties：

spring.jpa.hibernate.ddl-auto=create
spring.datasource.url=jdbc:mysql://localhost:3306/db_example?useSSL=false
spring.datasource.username=******
spring.datasource.password=*******

我将不胜感激，谢谢！
