java修改IE（chrome同）代理服务器配置---通过直接修改注册表

原创文章，转载请注明出处：http://passerbyy.iteye.com/blog/1285664 作者：passer_by

因为本文的操作，都是关于修改注册表的，所以希望能够谨慎操作。

方法有两种：
（一）通过自动生成注册表文件，再调用reg.exe命令
在说明本文之前，首先说明有比较简单的方法，java程序自动生成注册表文件*.reg，格式为：
REGEDIT4
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]
"ProxyEnable"=dword:00000001
"ProxyServer"="localhost:8080"
"ProxyOverride"="<localhost>"

然后调用，Runtime.getRuntime().exec( "reg.exe   import " + filename);

（二）通过调用registry的api修改
既然目前已经有现成的修改注册表的包jni的registry包，那我们就不费这个事做上面的操作了，registry jar包下载地址 http://www.trustice.com/java/jnireg/index.shtml ，另外发现openorg上也有类似的，但是类名改掉了，感兴趣的同学可以去搜搜。

IE代理服务器对应于注册表中字段：HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings下面的值：ProxyServer，ProxyEnable，ProxyOverride
ProxyEnable用来表示是否使用代理，用0,1表示，类型为REG_DWORD，不能为REG_SZ
ProxyServer用来表示代理服务器ip:port，如localhost:8080，类型为REG_SZ
ProxyOverride表示跳过代理的配置，比如跳过本地代理，该值为<local>

修改注册表类Register，以前也有类似的，但是没有区分REG_DWORD和REG_SZ两种类型

import com.ice.jni.registry.NoSuchKeyException;
import com.ice.jni.registry.RegDWordValue;
import com.ice.jni.registry.RegStringValue;
import com.ice.jni.registry.Registry;
import com.ice.jni.registry.RegistryException;
import com.ice.jni.registry.RegistryKey;

public class Register {

	// 把ICE_JNIRegistry.dll在的路径加载到java.library.path中，这里是放在classpath下面了
	static {
		System.setProperty("java.library.path",
				Register.class.getResource("/").getPath());
	}

	public String getValue(String folder, String subKeyNode, String subKeyName)
			throws SecurityException, NoSuchFieldException,
			IllegalArgumentException, IllegalAccessException,
			NoSuchKeyException, RegistryException {
		RegistryKey software = Registry.HKEY_CURRENT_USER.openSubKey(folder);
		RegistryKey subKey = software.openSubKey(subKeyNode);
		String value = subKey.getStringValue(subKeyName);
		subKey.closeKey();
		return value;
	}

	public int getIntValue(String folder, String subKeyNode, String subKeyName)
			throws SecurityException, NoSuchFieldException,
			IllegalArgumentException, IllegalAccessException,
			NoSuchKeyException, RegistryException {
		RegistryKey software = Registry.HKEY_CURRENT_USER.openSubKey(folder);
		RegistryKey subKey = software.openSubKey(subKeyNode);
		int value = ((RegDWordValue) subKey.getValue(subKeyName)).getData();
		subKey.closeKey();
		return value;
	}

	public boolean setIntValue(String folder, String subKeyNode,
			String subKeyName, int subKeyValue) throws NoSuchKeyException,
			RegistryException {
		RegistryKey software = Registry.HKEY_CURRENT_USER.openSubKey(folder);
		RegistryKey subKey = software.createSubKey(subKeyNode, "");
		RegDWordValue value = new RegDWordValue(subKey, subKeyName);
		value.setData(subKeyValue);
		subKey.setValue(value);
		subKey.flushKey();
		subKey.closeKey();
		return true;
	}

	public boolean setValue(String folder, String subKeyNode,
			String subKeyName, String subKeyValue) throws NoSuchKeyException,
			RegistryException {
		RegistryKey software = Registry.HKEY_CURRENT_USER.openSubKey(folder);
		RegistryKey subKey = software.createSubKey(subKeyNode, "");
		subKey.setValue(new RegStringValue(subKey, subKeyName, subKeyValue));
		subKey.flushKey();
		subKey.closeKey();
		return true;
	}
}

话说大学时用mfc写过ie代理动态修改的程序

C++搞这些还是方便的
