无法运行示例 Java EE 程序
Posted
技术标签:
【中文标题】无法运行示例 Java EE 程序【英文标题】：Unable to run a sample Java EE Program 【发布时间】：2017-05-06 12:18:28 【问题描述】：我刚刚开始研究 Java（非 web 开发背景）并下载了 JBoss 提供的名为 TicketMonster 的示例 Java EE 应用程序： https://github.com/jboss-developer/ticket-monster
我下载了项目并将其配置为 mysql 数据库。在我的数据库启动并运行后，我构建了这样的项目：
mvn clean package jboss:deploy -Pmysql
构建成功，我将 ticket-monster.war 文件部署到我的 Wildfly 服务器。但是，其余 api (JAX-RS) 都不起作用。
如果我请求 rest-api，例如“获取场地”，我会收到以下异常： http://textuploader.com/drip8
我尝试使用 PostgreSQL 数据库，但结果相同。数据库日志未显示错误。
任何有 Java EE 经验的人可以告诉我这里发生了什么？我要疯了，所以非常感谢所有帮助。
我的 Wildfly Standalone.xml 配置：

【问题讨论】：
【参考方案1】：似乎是双向关联问题。请参阅 this、this、this 和 this 帖子了解如何解决它。
看起来您下载的示例正在进行中，因为它是来自 jboss/ticket-monster（不是 jboss-DEVELOPER）的分支。如果您想尝试这个特定示例，请尝试从https://github.com/jboss/ticket-monster 获取。
否则，Oracle 有一个广泛的Java EE tutorial。 Netbeans有详细的step-by-step one。
【讨论】：
谢谢。我只是觉得奇怪的是他们会发布一个无法运行的演示应用程序，并且没有发布任何问题/错误？ 看来您使用的是“测试版”。我补充了我的答案。 谢谢，我尝试了非分叉的，但我仍然得到 JsonMappingException .. 这里真的有些不对劲。我只是无法指出这里做错了什么。以上是关于无法运行示例 Java EE 程序的主要内容，如果未能解决你的问题，请参考以下文章
