springMvc+jpa+mysql配置问题
配置的时候出现了如下错误，但是需要的包都添加了严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userDao': Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are:

java.lang.NoSuchMethodError: javax.persistence.EntityManager.getMetamodel()Ljavax/persistence/metamodel/Metamodel; --------------------编程问答--------------------
这是我的jar包，我才开始学，不太懂，不知道是不是兼容 --------------------编程问答-------------------- 这种情况下，有两步
1.建议还是找个合适的例子，网上应该会有很多，找个带jar包的，如果你自己选择jar包，很容易出现这种情况。
2.根据出错信息，找出相应的jar包，例如javax.persistence.EntityManager 这个报错，找不到方法，你试着去网上找更高版本的jar包，建议用maven管理jar比较好。
补充：Java , Eclipse
