使用spring数据插入示例获取错误

Question

我按照以下完整步骤URL加载数据并检索数据 http://www.objectdb.com/tutorial/jpa/eclipse/spring

我在持久性中添加的一件事情如下：因为我正在使用带有oracle数据库的glassfish。

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
    <persistence-unit name="seffPU" transaction-type="JTA">
        <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
        <jta-data-source>jdbc/seff</jta-data-source>
        <properties>
        <property name="javax.persistence.jdbc.driver" value="oracle.jdbc.OracleDriver"/>
        <property name="javax.persistence.jdbc.url" value="jdbc:oracle:thin:@192.168.100.2:1521:db"/>
        <property name="javax.persistence.jdbc.user" value="dm"/>
        <property name="javax.persistence.jdbc.password" value="tcg"/>

        </properties>
    </persistence-unit>
</persistence>

我正在使用Eclipse。

运行maven build时出现错误。
