Spring Boot - org.springframework.beans.factory.BeanCreationException：使用name创建bean时出错

我是Spring Boot的新手 . 我尝试将MySql数据库与hibernate连接，但是当我命令时，我收到此错误

mvn spring-boot：运行

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [com/autkusoytas/configuration/DatabaseConfig.class]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: org/dom4j/DocumentException

而DatabaseConfig在这里：

package com.autkusoytas.configuration;

import java.util.Properties;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.hibernate4.LocalSessionFactoryBean;
import org.springframework.orm.hibernate4.HibernateTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@Configuration
@EnableTransactionManagement
public class DatabaseConfig {

@Value("${db.driver}")
private String DB_DRIVER;

@Value("${db.password}")
private String DB_PASSWORD;

@Value("${db.url}")
private String DB_URL;

@Value("${db.username}")
private String DB_USERNAME;

@Value("${hibernate.dialect}")
private String HIBERNATE_DIALECT;

@Value("${hibernate.show_sql}")
private String HIBERNATE_SHOW_SQL;

@Value("${hibernate.hbm2ddl.auto}")
private String HIBERNATE_HBM2DDL_AUTO;

@Value("${entitymanager.packagesToScan}")
private String ENTITYMANAGER_PACKAGES_TO_SCAN;

@Bean
public DataSource dataSource() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName(DB_DRIVER);
    dataSource.setUrl(DB_URL);
    dataSource.setUsername(DB_USERNAME);
    dataSource.setPassword(DB_PASSWORD);
    return dataSource;
}

@Bean
public LocalSessionFactoryBean sessionFactory() {
    LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
    sessionFactoryBean.setDataSource(dataSource());
    sessionFactoryBean.setPackagesToScan(ENTITYMANAGER_PACKAGES_TO_SCAN);
    Properties hibernateProperties = new Properties();
    hibernateProperties.put("hibernate.dialect", HIBERNATE_DIALECT);
    hibernateProperties.put("hibernate.show_sql", HIBERNATE_SHOW_SQL);
    hibernateProperties.put("hibernate.hbm2ddl.auto", HIBERNATE_HBM2DDL_AUTO);
    sessionFactoryBean.setHibernateProperties(hibernateProperties);

    return sessionFactoryBean;
}

@Bean
public HibernateTransactionManager transactionManager() {
    HibernateTransactionManager transactionManager = new HibernateTransactionManager();
    transactionManager.setSessionFactory(sessionFactory().getObject());
    return transactionManager;
}

} // class DatabaseConfig

而且我也在使用这样的application.properties：

db.driver：com.mysql.jdbc.Driver db.url：jdbc：mysql：// localhost：3306 / test db.username：root db.password：hibernate.dialect：org.hibernate.dialect.MySQL5Dialect hibernate.show_sql ：true hibernate.hbm2ddl.auto：update entitymanager.packagesToScan：com.autkusoytas
