Eclipse+Maven+Hibernate5

依赖：

　　Mysql  8.0.11

　　Hibernate 5.2.6 Final

1、pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    </dependency>
    
    <dependency>
        <groupId>org.hibernate</groupId>

        <artifactId>mysql-connector-java</artifactId>
        <version>8.0.11</version>
    </dependency>
    
  </dependencies>
</project>

　　2、hibernate.cfg.xml，这里需要特别注意不要写错

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC 
  "-//Hibernate/Hibernate Configuration DTD 3.0//EN" 
  "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<!-- Version 8 MySQL hiberante-cfg.xml example for Hibernate 5 -->
<hibernate-configuration>
  <session-factory>
    <property name ="connection.driver_class"> com.mysql.cj.jdbc.Driver </property>
    <!-- property name="connection.driver_class">com.mysql.jdbc.Driver</property -->
    <property name ="connection.url">jdbc:mysql://localhost:3306/test?useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true</property>
    <property name ="dialect"> org.hibernate.dialect.MySQLDialect </property>
    <property name ="connection.username"> root </property>
    <property name ="connection.password"> password </property>
    <property name ="connection.pool_size">3</property>
    
    <!--property name="dialect">org.hibernate.dialect.MySQLDialect</property-->
    <property name ="current_session_context_class"> thread </property> 
    <property name ="show_sql"> true </property>
    <property name ="format_sql"> true </property>
    <property name ="hbm2ddl.auto"> update </property>
    
    <mapping resource="door.hbm.xml" />
  </session-factory>
</hibernate-configuration>

　　3、door.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"     
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.wyl">
    <class name="com.wyl.entity.Door" table="tb_door">
        <id name="id">
            <column name="id"></column>
            <generator class="native"></generator>
        </id>
        
        <property name="name">
             <column name="name"></column>
        </property>
        
        <property name="tel" type="java.lang.String">
            <column name="tel"></column>
        </property>
        
        <property name="addr" type="java.lang.String">
            <column name="addr"></column>
        </property>
    </class>

</hibernate-mapping>

　　4、在com.wyl.entity包下新建Door.java

package com.wyl.entity;

public class Door {
    private Integer id;
    private String name;
    private String tel;
    private String addr;
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getTel() {
		return tel;
	}
	public void setTel(String tel) {
		this.tel = tel;
	}
	public String getAddr() {
		return addr;
	}
	public void setAddr(String addr) {
		this.addr = addr;
	}
	@Override
	public String toString() {
		return "Door [id=" + id + ", name=" + name + ", tel=" + tel + ", addr=" + addr + "]";
	}
	
    
}

　　5、测试App.java

package com.wyl;

import java.util.List;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.query.Query;

import com.wyl.entity.Door;

public class App {
	public static void main(String[] args) {
		Configuration config = new Configuration().configure();
		SessionFactory sessionFactory = config.buildSessionFactory();
		Session session = sessionFactory.openSession();
		
		Query<Door> query = session.createQuery("from Door");
		List<Door> list = query.getResultList();
		
		System.out.println(list);
		
		session.close();
		sessionFactory.close();
		
	}
}

　　6、结果
