java - 在 java 中配置 hibernate 和 mysql 时出错

Question

我是 hibernate 新手。我收到了类似的错误找不到 hibernate.properties 并且拒绝用户 'root'@'localhost' 的访问(使用密码:YES)

我正在使用 MySqlWorkbench 版本 5.7.19和 hibernate 版本 5.2.6.Final带有eclipse氧的jdk 1.8

这是我的 hibernate.cfg.xml 文件

<hibernate-configuration>
<session-factory>
    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="hibernate.connection.password">gary@1234</property>
    <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/hibernate</property>
    <property name="hibernate.connection.username">root</property>
    <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
    <property name="hbm2ddl.auto">update</property>
</session-factory>

这里是 pom.xml

  <dependencies>
<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>3.8.1</version>
  <scope>test</scope>
</dependency>
<!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-core -->
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>5.2.6.Final</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java -->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.39</version>
    </dependency>

这是我的代码

public class App {
public static void main(String[] args) {
    Alien alien = new Alien();
    alien.setAid(101);
    alien.setAname("pawan");
    alien.setColor("purple");
    Configuration con = new Configuration().configure();
    SessionFactory sf = con.buildSessionFactory();
    Session session = sf.openSession();
    Transaction tx = session.beginTransaction();
    session.save(alien);
    tx.commit();
}}

这是pojo类

public class Alien {

@Id
private int aid;
private String aname;
private String color;

public int getAid() {
    return aid;
}

public void setAid(int aid) {
    this.aid = aid;
}

public String getAname() {
    return aname;
}

public void setAname(String aname) {
    this.aname = aname;
}

public String getColor() {
    return color;
}

public void setColor(String color) {
    this.color = color;
}

感谢大家抽出宝贵的时间。我得到了解决方案，只需将其更改为

Configuration con = new Configuration().configure("hibernate.cfg.xml").addAnnotatedClass(Alien.class);

实际上它并没有获取 hibernate.cfg.xml 和类的属性
