使用@JsonView时，从类加载器中看不到SynthesizedAnnotation

标签： java spring

我正在尝试使用Spring Framework的JsonView示例代码。

http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#mvc-ann-jsonview

当我使用Spring Framework 4.2.2.RELEASE时，它工作正常，但它不适用于4.2.3.RELEASE。

我认为这似乎是一个依赖性问题。 但是......，有什么不对？有没有人有任何想法？

这是我的pom.xml。

这是一个已知问题，似乎是一个依赖问题。看看https://jira.spring.io/browse/SPR-13696

  

您确定没有框架的混合版本吗？你可以在你的项目上运行mvn依赖项：list并检查所有Spring jar只使用4.2.3.RELEASE吗？如果是这种情况，请分享一个可以重现问题的项目。

感谢您的信息。但是它的记者是我的同事，项目是

https://github.com/syw2452/git_syw.git

幸运的是，我可以解决。

我们使用glassfish 4.1和glassfish在Application Server层类加载器上有jackson-annotaions.jar。 所以我向WEB-INF添加glassfish-web.xml并设置<class-loader delegate="false"/>。 然后这个应用程序工作正常。

自从SPR-13634以来，Spring的AnnotationUtils似乎改变了类加载器。 所以＆＃34;注释提供＆＃34; jar必须能够找到spring-core.jar。
