java - jparepository 错误创建 entitymanagerfactory

Question

现在我正在尝试使用 spring mvc 配置 jpa 数据。但是当我尝试在 tomcat 服务器上执行时出现异常。

我正在使用 tomcat 7.0.56这里是异常(exception):

谁能指导我解决这个问题？谢谢

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

如果您不需要时间编织(最有可能)，只需从 XML 配置中的实体管理器声明中删除 loadTimeWeaver 属性。

在这种情况下，您还必须从 jpaProperties 属性的 props 列表中删除名为 hibernate.ejb.use_class_enhancer 或将其值设置为 false。

---

但是，如果您需要时间编织让我们看看documentation :

...Further, in certain environments, this support enables load-time weaving without making any modifications to the application server’s launch script that will be needed to add -javaagent:path/to/aspectjweaver.jar or (as we describe later in this section) -javaagent:path/to/org.springframework.instrument-{version}.jar (previously named spring-agent.jar).

因此，尝试添加 JVM 参数:

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

path/to/ 更有可能指向您本地的 Maven 存储库。对于使用 Maven 设置 JVM 参数，您可以使用 MAVEN_OPTS 环境变量。在 Windows 中它看起来像:

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