Hibernate + PostgreSQL引发异常：找不到JDBC驱动程序类：org.postgresql.Drive

标签： java hibernate web-services postgresql jdbc

我使用jersey + hibernate编写了一个用于restful webservice的Java maven项目并且犯了这个错误：

javax.servlet.ServletException: org.hibernate.HibernateException: JDBC 
Driver class not found: org.postgresql.Drive
org.glassfish.jersey.servlet.WebComponent.service(WebComponent.java:419)

org.glassfish.jersey.servlet.ServletContainer.service(ServletContainer.java:
344)
org.glassfish.jersey.servlet.ServletContainer.service(ServletContainer.java:

根本原因：

JDBC驱动程序位于类路径中。

hibernate.cfg.xml文件：

        <!-- JDBC connection pool (use the built-in) -->

        <!-- SQL dialect -->

</hibernate-configuration>

有人可以帮忙吗？

答案 0 :(得分：1)

将PostgreSQL maven依赖项添加到您的pom文件

<dependency>
    <groupId>postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>9.1-901-1.jdbc4</version>
</dependency>

并在驱动程序

中添加缺少的r 
<property name="connection.driver_class">org.postgresql.Driver</property>

答案 1 :(得分：0)

此行中的错误：

<property name="connection.driver_class">org.postgresql.Drive</property>

上面写着Drive，应该将其更改为Driver：

<property name="connection.driver_class">org.postgresql.Driver</property>
