RegJ使用说明

一个简易的、可以用java操作注册表的包。

注意:注册表是系统重要数据,操作时请小心谨慎!

其功能有:

1,添加注册表项。
2,删除注册表项。
3,查询注册表项。
4,从reg文件导入注册表项。
5,把指定注册表项导出。
6,常规注册表位置的快捷操作。

下载地址:点击进入下载jar包

使用方法:

1,添加依赖,有下列两种情况:

①Eclipse直接添加jar:先下载这个jar包并把这个包导入到IDE里面,例如eclipse。不知道如何导入请查看教程:eclipse导入外部jar包
②Maven工程:在项目的配置文件pom.xml中的<dependencies>标签里加入下列依赖,此操作无需在上面手动下载jar包(推荐):

<dependency>
    <groupId>com.gitee.swsk33</groupId>
    <artifactId>reg-java</artifactId>
    <version>4.0.0</version>
</dependency>

2,导入com.gitee.swsk33.reg下所有类或者需要的类。

import com.gitee.swsk33.reg.*;

3,主要类与方法:

RegAdd:用于添加注册表项,其包含的方法:

  • static boolean add(String primaryKey, String name):在注册表里面添加空项
  • static boolean add(String primaryKey, String name, String data):在注册表里面添加项并指定其默认项的值,字符串值类型
  • static boolean add(String primaryKey, String name, String type, String data):在注册表里面添加项并指定其默认值的类型和值
  • static boolean add(String primaryKey, String name, String type, String objectName, String data):在注册表里面添加项并指定项中值的类型、名称和值(若该项已存在,则会在该项中添加值)

RegDelete:用于删除注册表项,其包含的方法:

  • static boolean del(String primaryKey, String name):删除注册表里面的某项及其所有子项
  • static boolean del(String primaryKey, String name, String objectName):删除注册表里面的某项的某个值
  • static boolean delDefaultValue(String primaryKey, String name):删除(清空)注册表里面的某项的默认值

RegExport:用于导出注册表项为reg文件,其包含的方法:

  • static boolean export(String primaryKey, String name, String filePath):导出注册表里面的某一项

RegImport:用于从reg注册表文件导入,其包含的方法:

  • static void importReg(String filePath):从注册表文件(reg文件)导入注册表

RegQuery:用于从查询注册表,其包含的方法:

  • static String query(String primaryKey, String name):查询注册表下的某项及其所有值的名称、类型和值
  • static String query(String primaryKey, String name, String objectName):查询注册表下的某项的值的信息
  • static Map<String, Map<String, String>> queryValue(String primaryKey, String name):精确查询注册表的值,查询注册表某一项的值及其子项的值
  • static String queryValue(String primaryKey, String name, String objectName):精确查询注册表的值,查询注册表某一项之下的值的值
  • static String queryDefault(String primaryKey, String name):查询注册表下的某项的默认值的信息
  • static String queryDefaultValue(String primaryKey, String name):精确查询注册表的值,查询注册表某一项默认值的值
  • static boolean isRegValueBlank(String primaryKey, String name, String objectName):检测注册表某一项下的指定的值是否为空白(值存在而无内容)
  • static boolean isRegExists(String primaryKey, String name):判断注册表下的某一项是否存在
  • static boolean isRegExists(String primaryKey, String name, String objectName):判断注册表下的某一项的值是否存在
  • static boolean isRegDefaultExists(String primaryKey, String name):判断注册表下的某一项的默认值是有内容(不为空)

KeyRegPlace:位于com.gitee.swsk33.reg.util下,常规关键位置的注册表操作:

  • static boolean addBootOption(String name, String exec):添加开机启动项
  • static boolean addFileOrDirRightMenu(String name, String exec):添加文件(夹)右键菜单
  • static boolean addFileOrDirRightMenu(String name, String exec, String iconPath):添加带图标的文件(夹)右键菜单
  • static boolean addDirectoryBackgroundMenu(String name, String exec):添加文件夹背景/桌面右键菜单
  • static boolean addDirectoryBackgroundMenu(String name, String exec, String iconPath):添加带图标的文件夹背景/桌面右键菜单
  • static boolean addUninstallInfo(String name, String installPath, String uninstallString):添加软件卸载信息
  • static boolean addUninstallInfo(String name, String installPath, String uninstallString, String iconPath, String version, long size):添加软件卸载信息
  • static boolean addUninstallInfo(UninstallInfo info):添加软件卸载信息

上述type(值的类型)参数可选常量对应如下:
RegDataType.REG_SZ:字符串值
RegDataType.REG_MULTI_SZ:多字符串值
RegDataType.REG_EXPAND_SZ:可扩展字符串值
RegDataType.REG_DWORD:DWORD值
RegDataType.REG_QWORD:QWORD值
RegDataType.REG_BINARY:二进制值
RegDataType.REG_NONE:无
上述primaryKey(注册表主键)参数可选常量对应如下:
RegPrimaryKey.HKCR:HKEY_CLASSES_ROOT
RegPrimaryKey.HKCU:HKEY_CURRENT_USER
RegPrimaryKey.HKLM:HKEY_LOCAL_MACHINE
RegPrimaryKey.HKU:HKEY_USERS
RegPrimaryKey.HKCC:HKEY_CURRENT_CONFIG

上述RegDataType和RegPrimaryKey位于com.gitee.swsk33.reg.param下。

详细的使用可以在调用类的方法时查看,IDE中会显示其中的详细文档

实例

例如给HKEY_CLASSES_ROOT里的AAM\shell里面加一个名为test的项:
RegAdd.add(RegPrimaryKey.HKCR, "AAM\\shell\\test");
例如给HKEY_CLASSES_ROOT里的AAM\shell里面加一个名为test的项,并指定其子项类型为字符串值且值为2333:
RegAdd.add(RegPrimaryKey.HKCR, "AAM\\shell\\test", RegAdd.REG_SZ, "2333");
注意:如果指定注册表存在,添加操作会将其覆盖!

例如把HKEY_CLASSES_ROOT里的AAM\shell导出到E盘,保存为exp.reg:
RegExport.export(RegPrimaryKey.HKCR, "AAM\\shell", "E:\\exp.reg");

注意,特殊符号不需要手动转义,在进行操作之前包会先对特殊符号进行转义再执行!
