现在我正在尝试用spring MVC配置jpa数据。但是我在tomcat服务器上尝试执行时遇到了异常。

有人能指导我解决这个吗？谢谢

异常说明:“必须从Java代理开始才能使用InstrumentationLoadTimeWeaver。请参见Spring文档”

如果不需要时间编织（很可能是这样），只需从XML配置中的实体管理器声明中删除loadtimeweaver属性即可。

在本例中，还必须从props列表中删除JPAProperties属性，名为hibernate.ejb.use_class_enhancer或将其值设置为false。

因此，尝试添加JVM参数：

-javaagent:path/to/org.springframework.instrument-4.2.0.RELEASE.jar

其中path/to/更可能指向本地Maven存储库。对于用Maven设置JVM参数，可以使用Maven_opts环境变量。在Windows中，它将如下所示：

set MAVEN_OPTS=-javaagent:"path/to/org.springframework.instrument-4.2.0.RELEASE.jar" %MAVEN_OPTS%
