项目在 Eclipse 中正常运行,但在导出到可运行的 jar 时不会运行



我在尝试导出独立应用程序时遇到问题。

当我使用eclise执行它时,它运行良好,但当我试图导出到可运行的jar时,它会给我一些错误。

我的persistence.xml看起来像

<persistence-unit transaction-type="RESOURCE_LOCAL" name="alctel_server_monitor">
    <provider>org.hibernate.ejb.HibernatePersistenceProvider</provider>
    <class>br.com.monitor.database.vo.Servidor</class>
    <class>br.com.monitor.database.vo.Banco</class>
    <class>br.com.monitor.database.vo.Servico</class>
    <class>br.com.monitor.database.vo.alerta.Alerta</class>
    <class>br.com.monitor.database.vo.alerta.AlertaAtivo</class>
    <class>br.com.monitor.database.vo.email.Email</class>
    <exclude-unlisted-classes>true</exclude-unlisted-classes>
    <properties>
        <property name="hibernate.connection.driver_class" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
        <property name="hibernate.connection.url" value="jdbc:sqlserver://192.168.99.222;databaseName=MONITOR;" />
        <property name="hibernate.connection.username" value="" />
        <property name="hibernate.connection.password" value="" />
        <property name="hibernate.format_sql" value="true" />
        <property name="hibernate.show_sql" value="false" />
        <property name="hibernate.dialect" value="org.hibernate.dialect.SQLServerDialect" />
        <property name="hibernate.hbm2ddl.auto" value="none" />
        <property name="hibernate.hbm2ddl.import_files_sql_extractor"
            value="org.hibernate.tool.hbm2ddl.MultipleLinesSqlCommandExtractor" />
        <property name="hibernate.connection.useUnicode" value="true" />
        <property name="hibernate.connection.characterEncoding"
            value="UTF-8" />
    </properties>
</persistence-unit>

它位于src/META-INF/persistence.xml

当我从终端运行它时,我得到的堆栈跟踪是:

位于java.lang.reflect.Method.ioke(未知源)网址:org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader.main(JarRsrcLoader.java:58)引起原因:javax.persistence.PersistenceException:找不到持久性单元位于org.hibernate.jpa.Hhibernate PersistenceProvider.getEntityManagerFactoryBuilderOrNull(hibernate Persistence Provider.java:99)位于org.hibernate.ejb.Hhibernate Persistence.getEntityManagerFactoryBuilderOrNull(hibernate Persistency.java:93)位于org.hibernate.jpa.Hhibernate PersistenceProvider.getEntityManagerFactoryBuilderOrNull(hibernate Persistence Provider.java:86)位于org.hibernate.ejb.Hhibernate Persistence.getEntityManagerFactoryBuilderOrNull(hibernate Persistency.java:101)位于org.hibernate.jpa.Hhibernate PersistenceProvider.createEntityManagerFactory(hibernate Persistence Provider.java:67)位于org.hibernate.ejb.Hhibernate Persistence.createEntityManagerFactory(hibernate Persistency.java:54)在javax.persistence.persistence.createEntityManagerFactory(persistence.java:55)

我不知道发生了什么,有人能帮我吗?

谢谢!

我遇到了同样的问题,我通过以下方式解决了:

右键单击项目>属性>Java构建路径>订单和导出,然后选择库

右键单击项目>导出…>可运行的JAR文件>将所需的库复制到生成的JAR 旁边的子文件夹
