使用Java读/写Windows注册表?
回答:
Java Native Access(JNA)是用于处理本机库的出色项目,并且通过Advapi32Util和Advapi32支持平台库(platform.jar)中的Windows注册表。
import com.sun.jna.platform.win32.Advapi32Util;import com.sun.jna.platform.win32.WinReg;
public class WindowsRegistrySnippet {
public static void main(String[] args) {
// Read a string
String productName = Advapi32Util.registryGetStringValue(
WinReg.HKEY_LOCAL_MACHINE, "SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion", "ProductName");
System.out.printf("Product Name: %s\n", productName);
// Read an int (& 0xFFFFFFFFL for large unsigned int)
int timeout = Advapi32Util.registryGetIntValue(
WinReg.HKEY_LOCAL_MACHINE, "SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Windows", "ShutdownWarningDialogTimeout");
System.out.printf("Shutdown Warning Dialog Timeout: %d (%d as unsigned long)\n", timeout, timeout & 0xFFFFFFFFL);
// Create a key and write a string
Advapi32Util.registryCreateKey(WinReg.HKEY_CURRENT_USER, "SOFTWARE\\StackOverflow");
Advapi32Util.registrySetStringValue(WinReg.HKEY_CURRENT_USER, "SOFTWARE\\StackOverflow", "url", "http://stackoverflow.com/a/6287763/277307");
// Delete a key
Advapi32Util.registryDeleteKey(WinReg.HKEY_CURRENT_USER, "SOFTWARE\\StackOverflow");
}
}
