PostgreSQL 9.2.1과 Hibernate 연결

PostgreSQL 9.2.1과 Hibernate 연결

---

빈 Spring MVC 프로젝트가 있고 Maven을 사용하여 Hibernate와 PostgreSQL 드라이버를 설치했습니다.

PostgreSQL을 Hibernate와 연결하는 방법을 보여주는 완전한 자습서가 부족합니다.

여기에 도움이 필요하십니까?

이것은 posgresql에 대한 hibernate.cfg.xml이며 posgresql에 대한 기본 최대 절전 설정을 도와줍니다.

<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>
        <property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
        <property name="hibernate.connection.username">postgres</property>
        <property name="hibernate.connection.password">password</property>
        <property name="hibernate.connection.url">jdbc:postgresql://localhost:5432/hibernatedb</property>



        <property name="connection_pool_size">1</property>

        <property name="hbm2ddl.auto">create</property>

        <property name="show_sql">true</property>



       <mapping class="org.javabrains.sanjaya.dto.UserDetails"/>

    </session-factory>
</hibernate-configuration>

프로젝트가 maven에 배치 src/main/resources되면 패키지 단계에서 복사됩니다.../WEB-INF/classes/hibernate.cfg.xml

이것은 postgresql 9.5를 연결하기위한 hibernate.cfg.xml 파일이며 이것은 기본 설정에 도움이됩니다.

 <?xml version='1.0' encoding='utf-8'?>

파일 위치가 src / main / resources / hibernate.cfg.xml 아래에 있어야합니다.

Yes by using spring-boot with hibernate configuration files we can persist the data to the database. keep hibernating .cfg.xml in your src/main/resources folder for reading the configurations related to database.
