我试图通过使用EclipseLink weaver解决这个问题:
-javaagent:/dev/tools/javaagents/eclipselink.jar
但问题1也有同样的例外
库版本
我正在使用:

这里有一些信息
在访问Spring上下文之前,请确保您没有访问类
另一个解决方案是使用静态编织。将
org.springframework.instrument-3.1.0.M2.jar
复制到tomcat/lib
目录中,然后重试。现在,我也在使用EclipseLink 2.2
和Spring 3.1
,如下所示。我的配置与你的略有不同。
您的EclipseLineKentityManager工厂中没有loadTimeWeaver
配置。我想,如果你用下面的方法就可以了
请使用您的Oracle DB

考虑到单元测试的工具,可以将其作为VM参数添加到maven surefire插件中
<plugin>

<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<argLine>-javaagent:lib/test/spring-instrument-4.0.2.RELEASE.jar</argLine>

假设弹簧仪器罐放置在相应位置
(为此,可以将以下依赖项临时添加到项目pom.xml中
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-instrument</artifactId>
<scope>test</scope>
</dependency>
org.springframework
弹簧乐器
测试
然后在构建之后,相应的工件从local.m2目录复制到project的lib/test目录。)Hi@James“确保在访问Spring上下文之前您没有访问您的类。”如何实现这一点,因为我面临着同样的问题。请提出建议。到2017年有解决方案吗?
<dependency>
