Question

我正在尝试使用openJPA faset将动态Web项目部署到TomEE Plus服务器。但是，当我在服务器上启动应用程序时，它会给我以下错误：

111 INFO [main] openjpa.Runtime - OpenJPA动态加载验证提供程序。 131 INFO [main] openjpa.Runtime - 启动OpenJPA 2.2.0 202 INFO [main] openjpa.jdbc.JDBC - 使用字典类＆＃34; org.apache.openjpa.jdbc.sql.MySQLDictionary＆＃34;。

Exception in thread "main" <openjpa-2.2.0-r422266:1244990 nonfatal user error> org.apache.openjpa.persistence.ArgumentException: This configuration disallows runtime optimization, but the following listed types 
were not enhanced at build time or at class load time with a javaagent: "

    de.webshop.internal.db.Stock

你有什么建议？

Answer 1

您可以在构建时增强，或者需要为运行时增强定义代理，例如：“ java -javaagent：./ lib / openjpa-all-2.2.2.jar ... com.xyz 。主要“

如何在运行时执行openJPA增强？
