篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了EclipseLink织入失败:java.lang.AbstractMethodError _persistence_shallow_clone相关的知识，希望对你有一定的参考价值。
最近在升级项目的版本，由jdk8.x升到jdk 11.x, 发现一个奇怪的EclipseLink异常：java.lang.AbstractMethodError does not define or inherit an implementation of the resolved method abstract _persistence_shallow_clone()
完整异常栈:
java.lang.AbstractMethodError: Receiver class com.apobates.forum.core.entity.BoardActionCollection does not define or inherit an implementation of the resolved method abstract _persistence_shallow_clone()Ljava/lang/Object; of interface org.eclipse.persistence.internal.descriptors.PersistenceObject.

BoardActionCollection 类是一个子类, 实现单表继承. 完全参考官方的示例: EclipseLink/Examples/JPA/Inheritance
具体代码如下:
/**
* 抽像的操作集合
*
* @author xiaofanku
* @since 20200514
*/
@Entity
@Table(name = "apo_action_event_set")
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "TYPE", discriminatorType = DiscriminatorType.STRING, length = 20)
@DiscriminatorValue("P")
public class ActionEventDescriptor implements Serializable
//ETC
/**
* 版块的操作集合
*
* @author xiaofanku
* @since 20200514
*/
@Entity
@DiscriminatorValue("B")
public class BoardActionCollection extends ActionEventDescriptor
//ETC
/**
* 话题的操作集合
*
* @author xiaofanku
* @since 20200514
*/
@Entity
@DiscriminatorValue("T")
public class TopicActionCollection extends ActionEventDescriptor
子类TopicActionCollection 织入成功, 只有BoardActionCollection子类的业务方法调用失败, 抛出上面的异常. 原来的织入设置，persistence.xml
<property name="eclipselink.weaving" value="true"/>
<property name="eclipselink.weaving.lazy" value="true"/>
<property name="eclipselink.weaving.internal" value="true"/>
用spring3 + EclipseLink 2.5.2 + jdk8 运行没问题, 后来升级到jdk8 + spring 5.0.7 + EclipseLink2.7.1 运行没问题. 当前异常的环境为: spring 5.2.6 + EclipseLink2.7.6 + jdk 11.0.2 + tomcat 9.x
原来一直以为是环境没配置对, 必竟是第一次写jdk 11的项目. 去EclipseLink官方文档一顿找，发现下面的文章:
AbstractMethodError: _persistence_shallow_clone()
eclipselink-static-weave-plugin
按此路子可以解决. 在编译时进行静态织入, 也省的项目启动时进行动态织入，项目的启动时间也缩短了. 注意改用静态织入需要在persistence.xml中进行如下变动：
<property name="eclipselink.weaving" value="false"/>
<property name="eclipselink.weaving.lazy" value="false"/>
<property name="eclipselink.weaving.internal" value="true"/>
项目pom.xml的build部分如下:
<build>
<finalName>ROOT</finalName>
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
</resource>
</resources>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
