生成JSON时Glassfish错误

Question

我开发了一个Android应用程序，现在我从其外部数据库及其服务器开始，通信由RESTful Web服务执行。

这个Android应用程序只生成和使用JSON中的信息，因此在我的Web服务外观中，我只想删除CRUD方法中对XML的任何提及，（由NetBeans自动生成）。

我的意思是，从这个：

@GET
@Override
@Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
public List<Counselor> findAll() {
    return super.findAll();
}

到此（没有MediaType.APPLICATION_XML）：

@GET
@Override
@Produces(MediaType.APPLICATION_JSON)
public List<Counselor> findAll() {
    return super.findAll();
}

问题在于，当我在GlassFish Server（4.1.1）中部署这些更改并使用我的浏览器进行一些测试时（只是想查看我的数据库数据），这个堆栈跟踪出错：

对此有何想法？

我希望自己解释一下......先谢谢!!

Answer 1

这是Glassfish 4.1.1 https://java.net/jira/browse/JERSEY-2888

中的错误

我能够以肮脏的方式修复它：

在glassfish / modules / org.eclipse.persistence.moxy.jar中修复META-INF / MANIFEST.MF 只需将以下内容附加到Import-Package：

,org.xml.sax.helpers,javax.xml.parsers;resolution:=optional,javax.naming;resolution:=optional

所以看起来像是：

并重启GF

btw：您可以使用

轻松编辑终端中的罐子

emacs org.eclipse.persistence.moxy.jar

Answer 2

杰克的回答非常有用 它确定了问题，并且在没有补丁时很有用
但我建议而不是编辑jar ，因为在2.6.1中修正了错误， 到下载： org.eclipse.persistence.moxy-2.6.1 from MVNRepository

从MVNRepository获取最新版本： https://mvnrepository.com/artifact/org.eclipse.persistence/org.eclipse.persistence.moxy

并替换它。
不要忘记关闭并重新打开IDE。
