那些遇到过的问题

JPA 使用 hibernate，将 AvailableSettings.USE_CLASS_ENHANCER 属性设置为 true 会引发 java.lang.ClassCircularityError

Bas*_*sit 5 spring-mvc hibernate-entitymanager maven-3 load-time-weaving tomcat8

我设置了 spring 应用程序。一切正常。但是当我将 Hibernate AvailableSettings.USE_CLASS_ENHANCER 属性设置为 true 时，我得到java.lang.ClassCircularityError.

这是我的配置。首先，我使用的是 log4j2。这是我的 log4j2 文件。

log4j-xinclude-appenders.xml：

<appenders>
    <Console name="Console" target="SYSTEM_OUT">
        <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
    </Console>

    <RollingFile name="WroxFileAppender" fileName="${filename}.log" filePattern="${filename}-%d{MM-dd-yyyy}-%i.log">      
        <PatternLayout pattern= "%d{HH:mm:ss.SSS} [%t] %X{id} %X{username} %-5level %c{36} %l: %msg%n" />

为什么我会收到这些 ClassCircularityError 错误。我做错了什么？我正在使用Maven, Java 8 update 60, Spring 4.2.1, Hibernate 5.0.2, Spring-data-JPA 1.9.0. Maven 依赖是否会导致这些问题？

如果我将属性设置为falselikeproperties.put(AvailableSettings.USE_CLASS_ENHANCER, "false");那么一切正常。我想使用它是因为(mappedBy)JPA 的反面导致的延迟加载问题。

谢谢
