Question

我正在尝试创建一个用Java编写的Azure函数，并使用function.json文件进行配置（而不是使用注释）。

开始使用MS tutorial（可以正常使用）。

接下来，我尝试修改类以删除Function注释，并在“没有注释的相同函数”部分中添加一个如here所示的function.json。

类源代码现在是：

public class Function {

    public static String hello(String req, ExecutionContext context) {
        return String.format("Hi, %s!", req);
    }

}

我的function.json文件是

{
    "scriptFile": "ServiceBusQueueMsgToLogWriter-1.0-SNAPSHOT.jar",
    "entryPoint": "com.oneadvanced.adv365.mgdsvc.azure.func.test1.Function.hello",
    "bindings": [
    {
        "type": "httpTrigger",
        "name": "req",
        "direction": "in",
        "authLevel": "anonymous",
        "methods": [ "post" ]
    },
    {
        "type": "http",
        "name": "$return",
        "direction": "out"
    }
    ]
}

运行命令的输出：

mvn clean package

包括输出：

AI: INFO 12-10-2017 21:50, 1: Configuration file has been successfully found as resource
AI: INFO 12-10-2017 21:51, 1: Configuration file has been successfully found as resource

[INFO] 0 Azure Function entry point(s) found.
[INFO]
[INFO] Step 2 of 6: Generating Azure Function configurations
[INFO] No Azure Functions found. Skip configuration generation.

这让我想知道function.json文件是不是在正确的位置......

有没有人知道将function.json文件放在用Java编写的Azure函数的正确位置？

我试过了：

在项目的根目录
在src / main / resources中（我认为这是典型的Java / Maven项目中此类事情的标准位置）
与Java源文件相同的文件夹

每种情况都有相同的结果:(

对于我应该做的事情，我会感激不尽。

谢谢，安迪

给定功能应用程序中所有功能的代码都存在于包含主机配置文件和一个或多个的根文件夹子文件夹，每个子文件夹都包含单独函数的代码。

示例结构 ：

wwwroot
 | - host.json
 | - mynodefunction
 | | - function.json
 | | - index.js
 | | - node_modules
 | | | - ... packages ...
 | | - package.json
 | - mycsharpfunction
 | | - function.json
 | | - run.csx

您可以在official doc找到上述说明。

但是，我注意到您的function.json文件未设置disabled属性。将disabled属性设置为false以启用提及here的功能。

{
  "bindings": [
    {
      "name": "myBlob",
      "type": "blobTrigger",
      "direction": "in",
      "path": "jaygong/test",
      "connection": "AzureWebJobsStorage"
    }
  ],
  "disabled": false
}

更新答案：

我尝试使用您通过配置function.json提供的步骤创建我自己的azure功能，然后我再现了您的问题！

我的功能代码：

package cn.gjj;

public class Function {
    public static String hello(String in) {
        return in;
    }
}

我的功能测试代码：

package cn.gjj;

import org.junit.Test;

import static org.junit.Assert.assertEquals;

/**
 * Unit test for Function class.
 */
public class FunctionTest {
    /**
     * Unit test for hello method.
     */
    @Test
    public void testHello() throws Exception {
        final Function function = new Function();

        final String ret = function.hello("function");

        assertEquals("function", ret);
    }
}

我的function.json文件：

{
  "scriptFile": "JayGongTestAzureFunction-1.0-SNAPSHOT.jar",
  "entryPoint": "cn.gjj.Function.echo",
  "bindings": [
    {
      "type": "httpTrigger",
      "name": "req",
      "direction": "in",
      "authLevel": "anonymous",
      "methods": [ "post" ]
    },
    {
      "type": "http",
      "name": "$return",
      "direction": "out"
    }
  ]
}

当我运行命令mvn clean package时，日志显示与您相同。

在仔细比较function.json配置方式和annotations方式后，我发现Project/target/azure-functions/functionName/文件夹的目录不同。

annotations方式：

function.json配置方式：

请注意，如果在function.json后找不到mvn compile文件，请在pom.xml文件中添加以下关键行。

<resources>
  <resource>
    <directory>${project.basedir}</directory>
       <includes>
          <include>host.json</include>
          <include>local.settings.json</include>
          **<include>function.json</include>**
       </includes>
    </resource>
</resources>

<强> 解决方案：

创建一个职位文件夹并将function.json文件移入其中。然后它适用于我。

请试一试。

希望它对你有所帮助。
