SQLException - 没有为jdbc：postgresql找到合适的驱动程序

时间：2018-03-12 03:43:03

标签： java postgresql jpa java-ee persistence.xml

我有问题。我创建了具有Persistence.xml凭据的EntityManager但是我给出了消息错误“找不到适合的jdbc驱动程序：postgresql / localhost：9999 / DB”。

我不明白我做错了什么，请你帮我或者给我一些如何解决这个问题的建议。提前谢谢。

我使用的配置是：

的persistence.xml：

    <persistence xmlns="http://java.sun.com/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
                      http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
             version="2.0">
  <persistence-unit name="DB-dev">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <class>com.development.rrhh.model.entity.entity1</class>
    <class>com.development.rrhh.model.entity.entity2</class>
    ...
    <properties>
      <property name="hibernate.connection.driver_class" value="org.postgresql.Driver" />
      <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect" />
      <property name="hibernate.connection.url" value="jdbc:postgresql://localhost:5432/DB_RRHH" />
      <property name="hibernate.connection.username" value="developer" />
      <property name="hibernate.connection.password" value="deve.951741" />
      <property name="hibernate.show_sql" value="true"/>
    </properties>
  </persistence-unit>
</persistence>

的pom.xml 

<project ...>
    <dependencies>
        ...
