java 用swt调用com组建之ie组建加强版

首先因为是调用ie的组建，所以有些机器默认的不是ie，就可能无法直接获取。所以有两点需要做的，1是设置ie为默认浏览器，2是先开一下ie。
先说一下，这个代码是通过进程调用，也可以理解为java进程和ie进程之间的通信。
另外，一些代码也是学习重用了网上的一些代码，但还是做了一些修改。
最后的效果是，打开一个自己预先写的网页，3秒钟之后会自动点击网页上的一个按钮，将html预先的值写入一个textarea中，然后java端获取这个值。
然后是代码部分
1，和之前一样，有一个超类SuperOcx.java

package outIE;
import org.eclipse.swt.ole.win32.OleAutomation;
import org.eclipse.swt.ole.win32.OleControlSite;
import org.eclipse.swt.ole.win32.OleListener;
import org.eclipse.swt.ole.win32.Variant;
import org.eclipse.swt.widgets.Composite;
public class SuperOcx extends Composite {
	protected OleAutomation player;
	protected OleControlSite controlSite;
	protected int Type;
	/**
	 * @param parent
	 * @param style
	 */
	public SuperOcx(Composite parent, int style) {
		super(parent, style);
	}

	protected int getType() {
		return Type;
	}

	protected void setType(int type) {
		Type = type;
	}

	public int getID(String name) {
		try {
			int[] ids = player.getIDsOfNames(new String[] { name });
			if (ids.length >= 0)
				return ids[0];
		} catch (RuntimeException e) {
			e.printStackTrace();
		}
		return -1;
	}
	public int[] getIDs(String... name) {
		try {
			int[] ids = player.getIDsOfNames(name);
			if (ids.length >= 0)
				return ids;
		} catch (RuntimeException e) {
			e.printStackTrace();
		}
		return null;
	}
	public Variant execute(String methodName) {
		int mid = getID(methodName);
		if (mid < 0)
			return null;

		Variant rtnv = player.invoke(mid);
		return rtnv;
	}
	public Variant getProperty(String parameter){
		int mid = getID(parameter);
		if(mid<0)return null;
		return player.getProperty(mid);
	}
	public Variant execute(String methodName, Variant[] parameter) {
		int mid = getID(methodName);
		if (mid < 0)
			return null;

		Variant rtnv = player.invoke(mid, parameter);
		return rtnv;
	}

	public Variant executes(String[] methodName, Variant[] parameter) {
		int[] mid = getIDs(methodName);
		if (mid == null)
			return null;
		int[] x = new int[1];
		x[0] = mid[1];
		Variant rtnv = player.invoke(mid[0], parameter, x);
		return rtnv;
	}

	/**
	 * 添加事件监听
	 * 
	 * @param eventID
	 * @param listener
	 */
	public void addEventListener(int eventID, OleListener listener) {
		controlSite.addEventListener(eventID, listener);
	}

	/**
	 * 移除事件监听
	 * 
	 * @param eventID
	 * @param listener
	 */
	public void removeEventListener(int eventID, OleListener listener) {

		controlSite.removeEventListener(eventID, listener);
	}
}

2，然后是外部调用ie的方式的封装，这里面的main方法可以试一下，是启动ie进程
AutomationClientSite.java

package outIE;

import org.eclipse.swt.SWT;
import org.eclipse.swt.SWTException;
import org.eclipse.swt.internal.ole.win32.COM;
import org.eclipse.swt.internal.ole.win32.GUID;
import org.eclipse.swt.internal.ole.win32.IUnknown;
import org.eclipse.swt.ole.win32.OLE;
import org.eclipse.swt.ole.win32.OleAutomation;
import org.eclipse.swt.ole.win32.OleClientSite;
import org.eclipse.swt.ole.win32.OleFrame;
import org.eclipse.swt.ole.win32.Variant;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Shell;

public class AutomationClientSite extends OleClientSite {
	public AutomationClientSite(Composite parent, int style, String progId) {
		super(parent, style);
		try {
			appClsid = getClassID(progId);
			if (appClsid == null)
				OLE.error(OLE.ERROR_INVALID_CLASSID);
			int[] address = new int[1];
			int result = COM.CoCreateInstance(getClassID(progId), 0, COM.CLSCTX_INPROC_SERVER | COM.CLSCTX_LOCAL_SERVER, COM.IIDIUnknown, address);
			if (result != COM.S_OK)
				OLE.error(OLE.ERROR_CANNOT_CREATE_OBJECT, result);
			objIUnknown = new IUnknown(address[0]);
		} catch (SWTException e) {
			dispose();
			disposeCOMInterfaces();
			throw e;
		}
	}

	protected GUID getClassID(String progId) {
		GUID guid = new GUID();
		char[] buffer = null;
		if (progId != null) {
			int count = progId.length();
			buffer = new char[count + 1];
			progId.getChars(0, count, buffer, 0);
		}
		if (COM.CLSIDFromProgID(buffer, guid) != COM.S_OK) {
			int result = COM.CLSIDFromString(buffer, guid);
			if (result != COM.S_OK)
				OLE.error(result);
		}
		return guid;
	}

	public static void main(String[] args) {
		Shell composite = new Shell();
		OleFrame frame = new OleFrame(composite, SWT.NONE);
		AutomationClientSite client = new AutomationClientSite(frame, SWT.NONE, "InternetExplorer.Application");
		OleAutomation ole = new OleAutomation(client);
		int[] ids = ole.getIDsOfNames(new String[] { "visible" });
		ole.setProperty(ids[0], new Variant(true));
	}
}

3,IEFrame.java 这个是对于IE控件的进一步封装

package outIE;
import org.eclipse.swt.SWT;
import org.eclipse.swt.SWTError;
import org.eclipse.swt.SWTException;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.ole.win32.OleAutomation;
import org.eclipse.swt.ole.win32.OleFrame;
import org.eclipse.swt.ole.win32.OleListener;
import org.eclipse.swt.ole.win32.Variant;
import org.eclipse.swt.widgets.Composite;
/**
 * IE控制
 * 
 */
public class IEFrame extends SuperOcx {
	public AutomationClientSite automationClientSite;
	/**
	 * session event
	 */
	public static final int OnStatusChanged = 1;//

	/**
	 * Create the composite
	 * 
	 * @param parent
	 * @param style
	 */
	public IEFrame(Composite parent, int style) {
		super(parent, style);
		createContents();
	}

	protected void createContents() {
		setLayout(new FillLayout());
		try {
			OleFrame frame = new OleFrame(this, SWT.NO_TRIM);
			automationClientSite = new AutomationClientSite(frame, SWT.NONE, "InternetExplorer.Application");
			player = new OleAutomation(automationClientSite);
			int[] ids = player.getIDsOfNames(new String[] { "visible" });
			player.setProperty(ids[0], new Variant(true));
		} catch (SWTException e) {
			throw new RuntimeException(e.getMessage(), e);
		} catch (SWTError e) {
			throw new RuntimeException(e.getMessage(), e);
		}
	}

	/**
	 * 跳转网址
	 * @param rgvarg
	 * @param rgdispidNamedArgs
	 * @return
	 */
	public long Navigate(String rgvarg, int rgdispidNamedArgs) {
		Variant v[] = new Variant[2];
		v[0] = new Variant(rgvarg);
		v[1] = new Variant(rgdispidNamedArgs);
		return execute("Navigate", v).getLong();
	}
	/**
	 * 用来获取dom的元素
	 * @param id
	 * @return
	 */
	public OleAutomation getElementById(String id) {
		Variant v[] = new Variant[1];
		v[0] = new Variant(id);
		return execute("getElementById", v).getAutomation();
	}
	@Override
	public void addEventListener(int eventID, OleListener listener) {
		super.addEventListener(eventID, listener);
	}

	@Override
	public void removeEventListener(int eventID, OleListener listener) {
		super.removeEventListener(eventID, listener);
	}
}

4,调用，里面有注释，可以自己看
OutIEPlayer.java

/**
 * 
 */
package outIE;

import org.eclipse.swt.SWT;
import org.eclipse.swt.ole.win32.OleAutomation;
import org.eclipse.swt.ole.win32.Variant;
import org.eclipse.swt.widgets.Shell;
public class OutIEPlayer {

	/**
	 * @param args
	 * @throws InterruptedException 
	 */
	public static void main(String[] args) throws InterruptedException {
			Shell shell = new Shell(SWT.CLOSE | SWT.MIN);
			IEFrame ieFrame = new IEFrame(shell, SWT.NONE);
			String url =System.getProperty("user.dir") + "\\test.html";
			String[] methodName = new String[] { "Navigate", "URL" };
			Variant[] rgvarg = new Variant[1];
			rgvarg[0] = new Variant(url);
			ieFrame.executes(methodName, rgvarg);
			
			Variant vdoc = ieFrame.getProperty("document");// 获取ie的Document元素
			OleAutomation doc = vdoc.getAutomation();// 转成ole
			Variant vplayer = doc.invoke(doc.getIDsOfNames(new String[] { "getElementById" })[0], new Variant[] { new Variant("play") });
			Thread.sleep(3000);
			// 登录模拟click
			vplayer.getAutomation().invoke(vplayer.getAutomation().getIDsOfNames(new String[] { "click" })[0]);
			//获取listinfo元素
			Variant VtextArea= doc.invoke(doc.getIDsOfNames(new String[] { "getElementById" })[0], new Variant[] { new Variant("listinfo") });
			OleAutomation textArea=VtextArea.getAutomation();
			//获取value属性的id
			int listinfoID = textArea.getIDsOfNames(new String[] { "value" })[0];
			//获取内容
			Variant list=textArea.getProperty(listinfoID);
			System.out.println(": "+list.getString());
	}

}

附件是用eclipse建立的工程，有基础班和加强版两个例子，仅供参考。

3 楼 ppg 2013-04-06  

navaa 写道

基础版用controlSite = new OleControlSite(frame, SWT.NO_TRIM, "Shell.Explorer");
而高级版用automationClientSite = new AutomationClientSite(frame, SWT.NONE, "InternetExplorer.Application");

请教一下楼主，有什么办法，即可以支持ie的dom操作，也支持ie的事件监听呢？

不好意思，长时间不用swt了。以前有一种方法是可以将ie内嵌在java里面。这种方式程序是什么都能做，只是应用上有局限性。

1 楼 navaa 2013-03-11  

经测试，貌似基础版本不支持ie的dom文档操作，加强版本不支持ie触发addEventListener操作。
