java.lang.NoSuchMethodError: javax.persistence.UniqueConstraint.name()Ljava/lang-优快云博客

本文介绍了解决Hibernate配置过程中遇到的NoSuchMethodError错误的方法。该问题源于MyEclipse自带的Java EE 5 Libraries与Hibernate JPA API之间的版本冲突。通过删除冲突的jar包或移除特定目录，成功解决了问题。

使用 ApplicationContext context = new ClassPathXmlApplicationContext("com/resources/spring-config.xml"); 时报的错，搞了好长时间，最后发现是 myeclipse自带的JAVA EE 5 Libraries中的javaee.jar与hibernate-jpa-2.0-api-1.0.0.Final.jar存在版本冲突，要么删了JAVA EE 5 Libaraies不用，要么将javaee.jar中的persitence目录删除。
