如何在JavaAzure函数中使用事件中心触发器

我正在尝试创建一个JavaAzure函数,该函数从Azure事件中心触发。下面是这些代码片段: https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-event-hubs-trigger?tabs=java#example

这是我的密码:

package com.function;

import com.microsoft.azure.functions.*;
import com.microsoft.azure.function.annotation.*;

import java.util.Optional;

public class function {

    @FunctionName("MTI")
    public void EventHubProcess(
        @EventHubTrigger(name = "msg", eventHubName = "mticallhub", connection = "EHubConnectionString"), String message, final ExecutionContext context) 
    {
        context.getLogger().info("Java HTTP trigger processed a request: " + message);
    }
}

以下是我在构建时遇到的错误:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project func-MTI-test-zyg-001: Compilation failure
[ERROR] /C:/JavaStuff/FunctionApps/func-MTI-test-zyg-001/src/main/java/com/function/Function.java:[34,105] illegal start of type

以下是VSCode中的错误弹出窗口:

我已经找了好几个小时了,一页又一页的谷歌搜索结果累坏了。我做错什么了?
