一、新建mvn项目。

mvn依赖：

 1 <dependencies>
 2         <!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-core -->
 3         <dependency>
 4             <groupId>org.hibernate</groupId>
 5             <artifactId>hibernate-core</artifactId>
 6             <version>5.6.7.Final</version>
 7         </dependency>
 8         <!-- https://mvnrepository.com/artifact/junit/junit -->
 9         <dependency>
10             <groupId>junit</groupId>
11             <artifactId>junit</artifactId>
12             <version>4.13.2</version>
13             <scope>test</scope>
14         </dependency>
15         <!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java -->
16         <dependency>
17             <groupId>mysql</groupId>
18             <artifactId>mysql-connector-java</artifactId>
19             <version>8.0.28</version>
20         </dependency>
21         <dependency>
22             <groupId>org.junit.jupiter</groupId>
23             <artifactId>junit-jupiter</artifactId>
24             <version>RELEASE</version>
25             <scope>compile</scope>
26         </dependency>
27         <!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-c3p0 -->
28         <dependency>
29             <groupId>org.hibernate</groupId>
30             <artifactId>hibernate-c3p0</artifactId>
31             <version>5.6.7.Final</version>
32         </dependency>
33 
34     </dependencies>

 

二、Program Setting -- Modules配置

 

 点击加号添加核心配置文件

demo：

 1 <?xml version='1.0' encoding='utf-8'?>
 2 <!DOCTYPE hibernate-configuration PUBLIC
 3         "-//Hibernate/Hibernate Configuration DTD//EN"
 4         "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
 5 <hibernate-configuration>
 6   <session-factory>
 7     <property name="connection.url">jdbc:mysql://localhost:3306/678</property>
 8     <property name="connection.driver_class">com.mysql.cj.jdbc.Driver</property>
 9     <property name="connection.username">root</property>
10     <property name="connection.password">678678</property>
11     <!-- <property name="connection.username"/> -->
12     <!-- <property name="connection.password"/> -->
13 
14     <!-- DB schema will be updated if needed -->
15     <!-- <property name="hibernate.hbm2ddl.auto">update</property> -->
16     <!--  hibernate配置  -->
17     <property name="hibernate.dialect">org.hibernate.dialect.MySQL8Dialect</property>
18     <property name="hibernate.show_sql">true</property>
19     <property name="hibernate.format_sql">true</property>
20     <!-- 表结构变化时执行修改表命令 不删表重建 -->
21     <property name="hibernate.hbm2ddl.auto">update</property>
22     <!-- 设置每次查询从数据库中读取的条数 MySQL数据库不支持（所以企业级涉及大数据量数据的存储基本采用Oracle数据库） -->
23     <property name="hibernate.jdbc.fetch_size">100</property>
24     <!-- 设置批量删除和批量更新 -->
25     <property name="hibernate.jdbc.batch_size">30</property>
26 
27     <!-- c3p0属性配置 -->
28     <!-- 配置启用c3p0连接池 -->
29     <property name="hibernate.connection.provider_class">org.hibernate.c3p0.internal.C3P0ConnectionProvider</property>
30     <property name="hibernate.c3p0.max_size">500</property>
31     <property name="hibernate.c3p0.min_size">1</property>
32     <!-- 设置缓存里最多有多少个statement对象 -->
33     <property name="hibernate.c3p0.max_statements">100</property>
34     <!-- 超时时间 -->
35     <property name="hibernate.c3p0.timeout">5000</property>
36     <!-- 配置每隔多少秒 扫描连接池所有连接，清理超时连接 -->
37     <property name="hibernate.c3p0.idle_test_period">2000</property>
38     <!-- 配置当连接池连接数耗尽时，每次向MySQL申请多少条连接 -->
39     <property name="hibernate.c3p0.acquire_increment">100</property>
43 
44   </session-factory>
45 </hibernate-configuration>

 

三、配置Database

 

 四、使用idea生成Entity及hbm.xml
