java - 未找到异常 hibernate.properties

Question

我尝试配置 hibernate 并出现此错误。我检查了 stackoverflow 上的所有答案，但没有帮助。我将 cfg 文件放入资源中，但没有帮助。

public class Dbconnect {

        public static void main(String[] args) throws Exception {

              StandardServiceRegistry standardRegistry = new StandardServiceRegistryBuilder().configure("/hibernate.cfg.xml").build();     

           Metadata metadata = new MetadataSources( standardRegistry )
                   .addAnnotatedClass( UserProfile.class )
                   .getMetadataBuilder()
                   .applyImplicitNamingStrategy( ImplicitNamingStrategyJpaCompliantImpl.INSTANCE )
                    .build();

            SessionFactory sessionFactory = metadata.getSessionFactoryBuilder().build();


        }
    }

我的项目结构

我的cfg文件

    <?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

    <session-factory>

        <property name="hibernate.connection.driver_class">com.mysql.cj.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/mytestdb</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.connection.password">pass</property>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
    </session-factory>
</hibernate-configuration>

更新。 添加了 mvn 依赖并存在时区错误。

Answer 1

您的 hibernate.cfg.xml 文件似乎位于路径 src/main/resources 中；当 maven 构建项目时，该路径将(默认情况下)位于类路径的根目录，因此要将其加载到您的上下文中，您应该使用:

new StandardServiceRegistryBuilder().configure("/hibernate.cfg.xml")

编辑

新的堆栈跟踪显示在您进行上述更改后现在可以找到 xml 文件；不幸的是，由于缺少库(jaxb)，它无法被解析。

使用以下内容更改 pom.xml 以添加依赖项:

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
</dependency>
<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>2.3.0</version>
    <scope>runtime</scope>
</dependency>
<dependency>
    <groupId>javax.activation</groupId>
    <artifactId>javax.activation-api</artifactId>
    <version>1.2.0</version>
</dependency>
