从早上开始，我一直在尝试生成休眠映射类，并且每个步骤都有问题。现在，当我尝试运行Hibernate Code Generation异常时，我面临NPE异常。我只在Hibernate Query结果的日志中看到以下异常：

Hibernate配置属性看起来像这样，在这里我也使用了不同版本的hibernate：
Hibernate.cfg.xml如下所示，我可以在hibernate透视图中看到这些表：
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.bytecode.use_reflection_optimizer">false</property>
<property name="hibernate.connection.driver_class">net.sourceforge.jtds.jdbc.Driver</property>
<property name="hibernate.connection.password">123456</property>
<property name="hibernate.connection.url">jdbc:jtds:sqlserver://127.0.0.1:1433/realtime-empty</property>
<property name="hibernate.connection.username">sa</property>
<property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property>
<property name="hibernate.search.autoregister_listeners">true</property>
<property name="hibernate.validator.apply_to_ddl">false</property>
</session-factory>
</hibernate-configuration>
最佳答案
是的，这里一样，不知道该如何解决。
Java版本：11.xx
Eclipse的Hibernate工具
版本：5.4.6.v20191022-0826
关于java - 从Hibernate Tools生成代码时，在Eclipse UI中使用NPE，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/59325187/
