私はSpring Bootで新しく、私はあなたの助けが必要です。私は私のMySQLのDB、JPA（Hibernateの）を設定しようとしていますが、私は次の例外を得た：Springブート/ Hibernate/MysqlはEntityManagerFactoryを作成できません
エラー名を持つBeanを作成する「のEntityManagerFactory」
によって引き起こされる.....クラスパスリソースで定義されています：org.hibernate.AnnotationException：表の連絡先に一意キー制約（user_idは、電子メール）を作成することができません：データベースの列が見つからない「USER_ID」.....
私はインターネットで答えを見つけることができません。私を助けてください。おかげさまで 私のコード：
CREATE TABLE IF NOT EXISTS users
(
id INTEGER PRIMARY KEY NOT NULL AUTO_INCREMENT,
login VARCHAR(45) NOT NULL,
password VARCHAR(45) NOT NULL,
full_name VARCHAR(100) NOT NULL
);
CREATE UNIQUE INDEX users_unique_login_idx ON users (login);
CREATE TABLE IF NOT EXISTS user_roles
(
user_id INTEGER NOT NULL,
role VARCHAR(45),
CONSTRAINT user_roles_idx UNIQUE (user_id, role),
FOREIGN KEY (user_id) REFERENCES users (id)
);
CREATE TABLE IF NOT EXISTS contacts (
id INTEGER PRIMARY KEY NOT NULL AUTO_INCREMENT,
user_id INTEGER NOT NULL,
first_name VARCHAR(45) NOT NULL,
last_name VARCHAR(45) NOT NULL,
patronymic VARCHAR(45) NOT NULL,
mobile_phone_number VARCHAR(15),
home_phone_number VARCHAR(15),
address VARCHAR(45),
email VARCHAR(30),
FOREIGN KEY (user_id) REFERENCES users (id)
);
CREATE UNIQUE INDEX contacts_unique_idx ON contacts (user_id);

アプリケーションの設定：Beanの

@ComponentScan
@EnableAutoConfiguration
public class SpringBootWebApplication {
public static void main(String[] args) {
SpringApplication.run(SpringBootWebApplication.class, args);

}
JPA構成：
@Configuration
@EnableTransactionManagement
public class JPAConfig {
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(dataSource());
em.setPackagesToScan("com.model");

Properties additionalProperties() {
Properties properties = new Properties();
properties.setProperty("hibernate.hbm2ddl.auto", "validate");
properties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
return properties;

}
spring-app.xmlの助けを借りてEntityManagerFactoryを設定しようとしましたが、まだ動作していません。

あなたのドメインクラス（ユーザー、連絡先）を確認できますか？また、application.propertiesはデータソースを作成するのに十分なものです。代わりに3つのデータソースがあります。また、あなたのpom.xmlを表示してください –
私はentityとpoomで私の質問を編集しました。 –
hibernate.cnf.xmlとJPAConfic.classのデータソースを削除する必要がありますか？ –
