Java Azure Function 不在本地执行

Question

Hi all, I'm working on Azure functions, I'm new to this, I have created a local java Azure function project using the below archetype:

*mvn archetype:generate -DgroupId=com.mynew.serverlesstest -DartifactId=serverlessexample - 
DarchetypeGroupId=com.microsoft.azure -DarchetypeArtifactId=azure-functions-archetype - 
DinteractiveMode=false*

*模板有一个简单的java function。

Upon executing a "mvn clean package" command, function.json gets generated in the target folder for the function, below is my function.json*

{
  "scriptFile" : "..\\serverlessexample-1.0-SNAPSHOT.jar",
  "entryPoint" : "com.mynew.serverlesstest.Function.hello",
  "bindings" : [ {
    "type" : "httpTrigger",
    "name" : "req",
    "direction" : "in",
    "authLevel" : "anonymous",
    "methods" : [ "get", "post" ]
  }, {
    "type" : "http",
    "name" : "$return",
    "direction" : "out"
  } ],
  "disabled" : false
}

在执行 mvn azure-functions:run 时，应用程序成功启动，我在命令提示符下得到以下信息：

[06-04-2020 07:26:55] Initializing function HTTP routes
[06-04-2020 07:26:55] Mapped function route 'api/hello' [get,post] to 'hello'

Http Functions:

      '000000000000000000000000852CF5C4'. 

但是当我尝试从 postman 中点击 api( http://localhost:7071/api/hello ) 时，我没有得到任何响应，我在命令提示符中看到以下内容：

[06-04-2020 07:29:04] Executing HTTP request: {
[06-04-2020 07:29:04]   "requestId": "af46115f-7a12-49a9-87e0-7fb073a66450",
[06-04-2020 07:29:04]   "method": "GET",
[06-04-2020 07:29:04]   "uri": "/api/hello"
[06-04-2020 07:29:04] }
[06-04-2020 07:29:05] Executing 'Functions.hello' (Reason='This function was programmatically called 
via the host APIs.', Id=7c712cdf-332f-413f-bda2-138f9b89025b)

在此之后没有任何反应：30 分钟后，我在命令提示符中收到如下超时异常：

Microsoft.Azure.WebJobs.Host: Timeout value of 00:30:00 was exceeded by function: Functions.hello.

有人可以提出可能导致这种情况的原因，为什么在 postman 中没有看到任何响应，我在这里做错了吗？ 我是否缺少任何配置内容？ 及时的帮助将不胜感激

请检查您的 function 代码。

根据您提供的信息，触发器已经被触发。 这意味着您的触发器内的代码逻辑尚未完成。 换句话说，你成功触发了触发器，但是你卡在了触发器的内部逻辑中。 请检查您的代码。
