java调用C#写的com组件

1.C#写com组件

开发环境 vs2005

1.新建工程:ClassLibrary1

2.右键点击工程->应用程序->程序集信息->使程序集com可见，打上勾

   右键点击工程->生成->为com Interop注册 打上勾

3.GuidAttribute中的Guid

  通过点击工具->创建GUID->选择4->New Guid->copy->粘贴到此外就行 

4.IPushEvent.cs

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;

namespace ClassLibrary1
{
    [GuidAttribute("D9490AF8-2372-4191-8E63-D0DBC9E6C81D"), InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
    public interface IPushEvent
    {
        void SyncRequestEvent(string msg);    
    }
}

5.IPushRender.cs

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;

namespace ClassLibrary1
{
    [GuidAttribute("71F09A88-2308-4fcd-9957-0488DD1584FC"),InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
    public interface IPushRender
    {
        string ResponseRenderAsyc(string content, object userstate);
    }
}

6.

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;

namespace ClassLibrary1
{
    [GuidAttribute("0E99CFC3-741C-406e-9E78-FB82E56C3F1C"),ClassInterface(ClassInterfaceType.AutoDispatch)]
    [ProgId("ClassLibrary1.PushServerProvider")]
    [ComSourceInterfaces(typeof(IPushEvent))]
    public class PushServerProvider : IPushRender
    {
        public delegate void RequestDelegate(string msg);
        public event RequestDelegate SyncRequestEvent; 

        public string ResponseRenderAsyc(string content, object userstate)
        {
            string retMessage = "这是从服务器端返回的:" + content;
            OnRequestEvent(retMessage);
            return retMessage;
        }

        public void OnRequestEvent(string msg)
        {            
            if (SyncRequestEvent != null)
            {
                try
                {
                    SyncRequestEvent(msg);
                }
                catch (Exception ex)
                {
                    System.Windows.Forms.MessageBox.Show(ex.Message);
                }
                
            }
        }
    }
}

 

6.编译以后，就要以在开发环境中注册了新生成的com组件,在客户环境中，通过regasm.exe注册com组件

regasm.exe的默认安装路径为:C:\Windows\Microsoft.NET\Framework\v2.0.50727\RegAsm.exe

7.可以通过ole/com object viewer可以查看com组件

8.java sdk1.4 通过jacob调用com组件http://danadler.com/jacob/

java测试程序

 

import com.jacob.activeX.*;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;
import com.jacob.com.*;

public class Test {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        ActiveXComponent mf = new ActiveXComponent("ClassLibrary1.PushServerProvider");
        Object o = mf.getObject();
        
        SensorEvents event = new SensorEvents();
        // hook it up to the sControl source
        DispatchEvents de = new DispatchEvents((Dispatch)o, event);
        
        System.out.println(Dispatch.call(mf,"ResponseRenderAsyc",new Variant( "123"),null));
        mf.safeRelease();
    }

}

 

9.java 事件注册类

 

import com.jacob.com.Variant;  

public class SensorEvents {

      public void SyncRequestEvent(Variant[] msg)
      {
         System.out.println("java callback for SyncRequestEvent!");
      }
}

 

在部署时需要将ClassLibrary1.dll和jacob-1.14.3-x86.dll

使用RegAsm.exe 路径\ClassLibrary1.dll /codebase注册dll

Run->Arguments->VM arguments->  -Djava.library.path=jacob-1.14.3-x86.dll 所在的文件夹路径
