问题描述
我想在运行时在Spring Boot应用程序中增强我的休眠实体。 休眠版本：5.4.21.Final 春季启动版本：2.3.3.RELEASE
所以我将这一行添加到了application.properties文件中：
spring.jpa.properties.hibernate.enhancer.enableDirtyTracking=true
这会出现以下错误：

然后我尝试将spring-instrument代理添加到Java命令行
java -javaagent:C:/devsbb/projekte/infop-all/infop-cloud/infop-rcp-server/src/main/resources/spring-instrument-5.2.9.RELEASE.jar -jar xyz.jar
这不会崩溃，但是会在日志中填充如下警告：
