• 不可能在单个App Service示例中直接混合不同的运行时堆栈。

创建一个Java应用程序服务对我们来说不是一个好的解决方案。

• 在不创建单独的应用服务的情况下，我们可以使用Docker容器化.NET Core和Java应用程序。您可以将.NET Core 7 Mass Transit主机和Java可执行文件（DoSomeThing.jar）打包到单个容器中，请查看下面的模板。

# Set the base image to a Linux distribution that supports both .NET Core and Java
FROM mcr.microsoft.com/dotnet/aspnet:7.0-jdk11

# Set the working directory inside the container
WORKDIR /app

# Copy the .NET Core project files to the container
COPY MyMassTransitHost.csproj .

# Restore the .NET Core dependencies
RUN dotnet restore

# Copy the entire project to the container
COPY . .

# Build the .NET Core application
RUN dotnet publish -c Release -o out

# Copy the Java application (DoSomeThing.jar) to the container
COPY DoSomeThing.jar .

# Set the entry point to start both the .NET Core MassTransit Host and the Java application
CMD ["sh", "-c", "dotnet /app/out/MyMassTransitHost.dll & java -jar /app/DoSomeThing.jar"]

字符串

• 将Docker镜像推送到容器注册表。在门户中创建应用服务时，运行时可以是.Net，发布应该是Docker容器。

的数据

• 使用自定义Docker镜像部署.NET Core App Service。
• 一旦您的.NET Core App Service使用自定义Docker映像运行，请更新MassTransit命令处理程序以执行Java命令。

using System.Diagnostics;

public class MyCommandHandler
{
    public void HandleCommand()
    {
        // Replace "/path/to/java" with the appropriate path to the Java executable in the container
        string javaExecutable = "/path/to/java";
        
        // Replace "/app/DoSomeThing.jar" with the actual path to the JAR file inside the container
        string jarFile = "/app/DoSomeThing.jar";
        
        // Replace "YourJavaOptions" with any additional Java options you want to pass
        string javaOptions = "YourJavaOptions";
        
        ProcessStartInfo startInfo = new ProcessStartInfo
        {
            FileName = javaExecutable,
            Arguments = $"{javaOptions} -jar {jarFile}",
            RedirectStandardOutput = true,
            RedirectStandardError = true,
            UseShellExecute = false,
            CreateNoWindow = true
        };
        
        using (Process process = new Process())
        {
            process.StartInfo = startInfo;
            process.Start();
            
            // You can optionally read the process output if needed
            string output = process.StandardOutput.ReadToEnd();
            string error = process.StandardError.ReadToEnd();
            
            process.WaitForExit();
        }
    }
}

型
这样我们就可以在同一个应用服务中直接执行Java JAR文件。
