Java 获取spring数据插入示例的错误

我按照下面的

URL

加载数据并检索数据

我在持久化中只添加了以下内容，因为我将glassfish与oracle数据库一起使用

<?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>

您可以发布控制器dao的代码吗？也可以发布您的spring-servlet.xml。错误似乎是在尝试为您的数据源创建bean时发生的。
