在 Java 中使用 Visual Studio Code 的 Azure Functions 项目
Posted
技术标签:
【中文标题】在 Java 中使用 Visual Studio Code 的 Azure Functions 项目【英文标题】：Azure Functions project using Visual Studio Code in java 【发布时间】：2020-07-23 17:16:59 【问题描述】：我正在尝试使用 VSCode 创建 azure 函数并将其部署到 azure。我按照描述的官方文档进行操作，
https://docs.microsoft.com/en-us/azure/azure-functions/functions-create-first-function-vs-code?pivots=programming-language-java。
按照本文档中的说明进行了所有操作，但在到达“在本地运行函数”部分时按 F5 时出现错误。我通过在互联网上搜索尝试了一些东西，但它们都不起作用。我注意到在 2017 年报告的官方 github 帐户上有一个未解决的问题
https://github.com/Microsoft/function-demo-java-on-azure/issues/3
这让我想知道这个问题还存在吗？
已经在这方面花费了很多时间，但无法让它发挥作用。任何帮助表示赞赏
Environment:
VS Code: v1.44.0
jdk 11.0.3
node v12.16.1
maven v3.6.3
使用命令 npm install -g azure-functions-core-tools@3 成功安装 azure function core tools
这是完整的错误跟踪

【问题讨论】：
【参考方案1】：原来问题出在不兼容的java版本上。目前 azure 函数仅支持 JDK8，但我使用的是 JDK11。切换到正确的java版本后，问题就解决了。
【讨论】：
通过将JAVA_HOME 环境变量更改为 JDK 8 并重新启动 VS Code，我能够构建该函数，但是当我尝试启动它时，我得到：Java 11 or more recent is required to run the Java extension. Please download and install a recent JDK. You can still compile your projects with older JDKs by configuring - java.configuration.runtimes。它说“由于 vscode-java 0.65.0，Java 11 是最低要求的版本。”.
@Thomas Java 11 需要运行 vscode-java 本身，如文档中所述。由于您想针对 Java 8 进行编译，因此您需要在 java.configuration.runtimes 中配置 JavaSE-1.8："java.configuration.runtimes": [ "name": "JavaSE-1.8", "path": "/path/to/jdk-8", , ]，完全按照github.com/redhat-developer/vscode-java/wiki/…中的说明进行【参考方案2】：
我遇到了同样的问题，使用 Azure Functions 创建的默认 pom.xml 在使用 Java 11 时会出现此错误。
我发现 Azure 自 2021 年 10 月 26 日起增加了对 Java 11 的支持。
https://azure.microsoft.com/en-in/updates/java-11-support-for-azure-functions-is-now-generally-available/
但默认的 pom 仍然带有 1.8 的支持配置。
我使用了这个https://docs.microsoft.com/en-us/azure/azure-functions/functions-reference-java?tabs=bash%2Cconsumption#java-versions 作为参考并更新了 pom.xml 如下使其在 Java 11 中编译和运行。
