阻塞的顶点线程
Blocked vertx threads
我必须学会使用以下方法开发微服务：
- Java 8
- 顶点 3.9
- 行家 3.6
- MongoDB 超过 Docker 19.03.1
作为 IDE 我正在使用 Intellij
我正在处理的代码是这样的：

Vertx 线程被阻塞。
在邮递员中我尝试测试路由 localhost:9090/create/ 并且它 returns 错误 500
我知道问题很长，但说真的我不知道该怎么做，我一直在寻找解决方案，但事实是我真的不明白我的错误是什么或发生了什么，我需要你的帮助。非常感谢
如果您查看中间的堆栈跟踪，它会报告它试图连接到 Mongo 数据库的主机拒绝了连接。确保它是可达的。
我敢打赌，您看到的 500 错误是由于您尝试使用 mongo 客户端而导致的空指针异常，即使它未能初始化并且从未分配变量。
第一个和第三个堆栈跟踪抱怨在启动服务器时绑定到端口花费的时间太长。 This might be an issue in the underlying netty library.

Vertx 线程被阻塞。
在邮递员中我尝试测试路由 localhost:9090/create/ 并且它 returns 错误 500
我知道问题很长，但说真的我不知道该怎么做，我一直在寻找解决方案，但事实是我真的不明白我的错误是什么或发生了什么，我需要你的帮助。非常感谢
如果您查看中间的堆栈跟踪，它会报告它试图连接到 Mongo 数据库的主机拒绝了连接。确保它是可达的。
我敢打赌，您看到的 500 错误是由于您尝试使用 mongo 客户端而导致的空指针异常，即使它未能初始化并且从未分配变量。
第一个和第三个堆栈跟踪抱怨在启动服务器时绑定到端口花费的时间太长。 This might be an issue in the underlying netty library.
