1. 最近在学习springcloud,搭建初始环境的时候遇到了这个问题, 在启动SpringBoot的时候不成功,弹出如下错误

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor$PersistenceElement.<init>(PersistenceAnnotationBeanPostProcessor.java:671)

The following method did not exist:

    javax.persistence.PersistenceContext.synchronization()Ljavax/persistence/SynchronizationType;

The method's class, javax.persistence.PersistenceContext, is available from the following locations:

    jar:file:/J:/IDEA/com.itcast/lib/javax.persistence.jar!/javax/persistence/PersistenceContext.class
    jar:file:/J:/Java/repository/javax/persistence/javax.persistence-api/2.2/javax.persistence-api-2.2.jar!/javax/persistence/PersistenceContext.class

It was loaded from the following location:

    file:/J:/IDEA/com.itcast/lib/javax.persistence.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of javax.persistence.PersistenceContext


Process finished with exit code 1

2.解决方法
在当前项目的库中删除提示的jar包 ,这样就默认只调用J:/Java/repository下的jar包,再试一下就可以正常启动了
