Glassfish MySQL Hibernate 无法构建 Hibernate SessionFactory
Glassfish MySQL Hibernate Unable to build Hibernate SessionFactory
我在使用 Glassfish/Payarus 和 Hibernate 的 Web 应用程序中无法连接到 MySQL 数据库。
我已经创建了一个 JDBC 连接池“test_db”和一个 JDBC 资源“jdbc/TestDB”并且可以成功 ping 通它。
<jdbc-connection-pool datasource-classname="com.mysql.jdbc.jdbc2.optional.MysqlDataSource" steady-pool-size="1" name="test_db" res-type="javax.sql.DataSource">
<property name="password" value="test" />
<property name="username" value="testUser" />
<property name="url" value="jdbc:mysql://localhost:3306/test_db" />
</jdbc-connection-pool>
<jdbc-resource pool-name="test_db" jndi-name="jdbc/TestDB" />
我在以下文件夹中有一个“mysql-connector-java-5.1.39”：
payaras/glassfish/domains/myDomain/lib
payaras/glassfish/domains/myDomain/lib/ext
payaras/glassfish/lib
这是我的 persistence.xml 文件
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence" version="2.1">
<persistence-unit name="test" transaction-type="JTA">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<jta-data-source>jdbc/TestDB</jta-data-source>
<properties>
<!-- Does not work without these properties either -->
<!-- Configuring JDBC properties -->
<property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/test_db" />
<property name="javax.persistence.jdbc.user" value="testUser" />
<property name="javax.persistence.jdbc.password" value="test" />
<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
<property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.SunOneJtaPlatform" />
<!-- Hibernate properties -->
<property name="hibernate.show_sql" value="true" />
<property name="hibernate.format_sql" value="true" />
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect" />
<property name="hibernate.hbm2ddl.auto" value="validate" />
</properties>
</persistence-unit>
</persistence>
但是每次我尝试部署我的应用程序时，我都会收到以下由 NullPointerException.

据我所知，Hibernate 无法连接到 mysql，但我不明白为什么。
映射没问题。至少在我的单元测试中它可以与 H2 DB 一起使用。我也用一个简单的实体对测试应用程序进行了尝试。
希望大家能帮帮我。
提前致谢

persitence.xml 文件中的以下行导致错误：
