Java OpenJPA和Spring引导配置
我正在为SpringBoot应用程序的基本配置而挣扎，OpenJPA作为jpa实现。基本上，我总是以以下方式结束： 原因：org.apache.openjpa.util.MetaDataException:未增强类型“class com.openjpa.example.Customer” 我的配置如下所示：Java OpenJPA和Spring引导配置,java,jpa,spring-boot,openjpa,Java,Jpa,Spring Boot,Openjpa,我正在为SpringBoot应用程序的基本配置而挣扎，OpenJPA作为jpa实现。基本上，我总是以以下方式结束： 原因：org.apache.openjpa.util.MetaDataException:未增强类型“class com.openjpa.example.Customer” 我的配置如下所示： package com.openjpa.example; @SpringBootApplication public class Application extends J

有人知道这里出了什么问题吗？这里是pom条目，用于在构建时增强实体类。这对我有用。 另外请注意，您需要META-INF/persistence.xml来在构建时增强类，而在运行时则不需要。因此，您可以在创建jar时排除persistence.xml
