嵌入Neo4J的Jersey web应用程序在Tomcat服务器上不能正确关闭

Question

初步说明：我在SO上查找了类似的问题，其中一个与我最相似的问题是：无法关闭Tomcat内的neo4j jetty服务器。我试过那里提出的所有解决办法，但都没有成功。

我在Tomcat上运行嵌入Neo4j数据库的Jersey应用程序时遇到了关机问题。部署（使用Maven 3.3.9)工作正常，数据库也启动了，但是在重新部署/取消部署时，我会得到一个Tomcat警告：

设置：

• Java版本:1.8.0_121
• Maven版本:3.3.9

在原始应用程序中使用：

• Tomcat版本6、8和9
• Neo4J版本2.2.3、2.2.5和3.1
• 泽西版本1.19和2.22.1

在这里报道的简单app中：

• Tomcat 8和9
• NEO4J 3.1
• 泽西2.22.1

更新2017-03-02我已经更新到Tomcat9，并将远程shell连接添加到上面的应用程序代码中。在我所做的GitHub repo中，我添加了@jerome-b建议的一个简单的单元测试，以显示远程shell端口在关机时不会被释放。

Answer 1

我向Neo4J(#8929)提交了一个问题。这是一个bug（端口保持绑定直到JVM终止），在问题#8949中提出了一个修复方案。
