java - 无法使用 eclipse link 和 oracle db 生成表 - IllegalBlockSizeException

Question

我创建了一个动态 Web 项目，并在我的 eclipse mars 中添加了 JPA 方面。在我的构建路径中，我有:jdk8、EclipseLink 2.6、JPA 2.1、Tomcat 8、Oracle 瘦驱动程序(ojdbc14.jar)；

有一个奇怪的问题，因为同一个项目在某些机器上可以运行，但在其他机器上却不能运行。

出于这个目的，我认为 tomcat 并不是必需的，因为我只想从一个简单的 jpa 项目中的实体生成表。

我创建了两个 jpa 实体，并将 persistence.xml 设置为指向我的 Oracle 数据库(Ping 成功):

persistence.xml

<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">

不幸的是，当我运行 JPA 工具>从实体创建表时...我收到以下错误:

Answer 1

这与已知的 bug 相关2.6.5-RC1 版本已修复此问题。它还可以按预期与最新的 2.6.5-RC2 候选版本(自 2017 年 6 月起提供)配合使用。

如果您有 Maven 项目，请更改 EclipseLink 依赖项的版本字符串，如下所示:

 <dependency>
     <groupId>org.eclipse.persistence</groupId>
     <artifactId>eclipselink</artifactId>
     <version>2.6.5-RC2</version>
 </dependency>

如果这是一个独立项目，请查找最新的2.6.5-RC2 jar file on Maven Central 。只需删除旧的 jar 文件并将新的文件放入应用程序的类路径中即可。

希望有帮助。
