java - Java 中的 Azure Function 无法在本地运行

Question

我正在尝试使用 IntelliJ 在我的 Mac 上本地运行 Azure 函数。我在本教程中一步一步完成了所有操作:https://learn.microsoft.com/en-us/azure/azure-functions/functions-create-maven-intellij但是当我启动项目控制台时显示错误

`Azure Functions Core Tools (3.0.2912 Commit hash: bfcbbe48ed6fdacdf9b309261ecc8093df3b83f2)

No job functions found. Try making your job classes and methods public. If you're using binding extensions (e.g. Azure Storage, ServiceBus, Timers, etc.) make sure you've called the registration method for the extension(s) in your startup code (e.g. builder.AddAzureStorage(), builder.AddServiceBus(), builder.AddTimers(), etc.).
For detailed output, run func with --verbose flag.

`我认为问题出在语言 worker 身上。

JAVA_HOME:

which java
/usr/bin/java

我也尝试过 func start ，结果相同，最后我用 Visual studio 代码尝试了它，但出现了相同的错误。

在java中本地运行Azure Function的唯一方法是使用archetype生成项目mvn archetype:generate -DarchetypeGroupId=com.microsoft.azure -DarchetypeArtifactId=azure-functions-archetype -DjavaVersion=8 然后mvn package mvn azurefunctions:run

有人有相关问题吗？ func 开始为 java 工作吗功能？

Answer 1

语言 worker java的Java路径在安装目录azure-function-core-tools@3/%version/workers/java的配置文件worker.config.json中设置

{
    "description": {
        "language": "java",
        "extensions": [".jar"],
        "defaultExecutablePath": "/usr/bin/java",
        "defaultWorkerPath": "azure-functions-java-worker.jar",
        "arguments": ["-XX:+TieredCompilation -XX:TieredStopAtLevel=1 -noverify -Djava.net.preferIPv4Stack=true -jar", "%JAVA_OPTS%"]
    }
}

您需要将 defaultExecutablePath 从 "%JAVA_HOME%/bin/java 更改为 java 可执行文件的绝对路径(例如 /usr/bin/java )。

可以通过readlink -f $(which func)找到安装目录
