将PostgreSQL 9.2.1连接到Hibernate

我有一个空白的Spring MVC项目，我使用Maven安装了Hibernate和PostgreSQL驱动程序。

我在完整的教程上显示了如何连接PostgreSQL和Hibernate。

任何帮助吗？

Answer 1

这是posgresql的hibernate.cfg.xml文件，它将帮助您使用posgresql的基本hibernateconfiguration。

<!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> 

Answer 2

如果项目maven将其放置在src/main/resources ，则在包阶段将其复制到../WEB-INF/classes/hibernate.cfg.xml

Answer 3

这是连接postgresql 9.5的hibernate.cfg.xml文件，这有助于你的基本configuration。

  <?xml version='1.0' encoding='utf-8'?> <!-- ~ Hibernate, Relational Persistence for Idiomatic Java ~ ~ License: GNU Lesser General Public License (LGPL), version 2.1 or later. ~ See the lgpl.txt file in the root directory or <http://www.gnu.org/licenses/lgpl-2.1.html>. --> <!DOCTYPE hibernate-configuration SYSTEM "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration > <session-factory> <!-- Database connection settings --> <property name="connection.driver_class">org.postgresql.Driver</property> <property name="connection.url">jdbc:postgresql://localhost:5433/hibernatedb</property> <property name="connection.username">postgres</property> <property name="connection.password">password</property> <!-- JDBC connection pool (use the built-in) --> <property name="connection.pool_size">1</property> <!-- SQL dialect --> <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property> <!-- Enable Hibernate's automatic session context management --> <property name="current_session_context_class">thread</property> <!-- Disable the second-level cache --> <property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property> <!-- Echo all executed SQL to stdout --> <property name="show_sql">true</property> <!-- Drop and re-create the database schema on startup --> <property name="hbm2ddl.auto">create</property> <mapping class="com.waseem.UserDetails"/> </session-factory> </hibernate-configuration>

确保文件位置应该在src / main / resources / hibernate.cfg.xml下
