下载安装好后可以如图把wkhtmltox配置到环境变量中去，方便使用

测试代码：

import java.io.*;

public class HtmlToImage{

public static void main(String[] args) {
ProcessBuilder pb = new ProcessBuilder("wkhtmltoimage", 
"www.baidu.com", "D:\\test.png");
Process process;
try{
process = pb.start();
BufferedReader errStreamReader = new BufferedReader(
new InputStreamReader(process.getErrorStream()));
System.out.println("read errStreamReader");
String line = null;
line = errStreamReader.readLine();
while(line != null){
System.out.println(line);
line = errStreamReader.readLine();
}
process.destroy();
System.out.println("destroyed process");
} catch (IOException e) {
e.printStackTrace();
}
}
}

测试调用命令行：以后便于使用wkhtmltox

import java.io.*;

public class CommandTest{

public static void main(String[] args) {
//open notepad
  //       try {   
  //               Process proc=Runtime.getRuntime().exec("notepad");   
  //       } catch (IOException e) {
  //           e.printStackTrace();   
  //       }

//open baidu by IE
// try {   
  //               String exeFullPathName="C:/Program Files/Internet Explorer/IEXPLORE.EXE";   
//         String message="www.baidu.com";   
//         String[] cmd={exeFullPathName,message}; 

//         Process proc=Runtime.getRuntime().exec(cmd); 

  //       } catch (IOException e) {
  //           e.printStackTrace();   
  //       }

        try { 
String[] cmd = {"cmd", "/c", "C:\\Program Files (x86)\\Tencent\\QQ\\QQProtect\\Bin\\QQProtect.exe"};
        Runtime.getRuntime().exec(cmd); 
        //why 这里不知道为什么不可以直接用，希望看到的会的指点下
        //Runtime.getRuntime().exec("cmd /c start C:\\Program Files (x86)\\Tencent\\QQ\\QQProtect\\Bin\\QQProtect.exe");

        } catch (IOException e) {
            e.printStackTrace();   
        }

}
}
