selenium 关键字驱动部分设计思路

说明：

1.以下的代码亲测直接可用，

2.设计思路来自博客园的张飞_ :http://www.cnblogs.com/zhangfei/p/5330994.html / http://www.cnblogs.com/zhangfei/p/

3.重点在于理解当中的设计思路，如果问题需要讨论可以联系我QQ：316567803 或者给我留言；

7.person 和 MoveDisk类

 1 package keyWordsDriver;
 2 
 3 /**
 4  * 
 5  */
 6 public class Person {
 7    void getTheCommandFromTeacher(){}
 8     void findTheDeskAtA(){}
 9     void moveDeskToB(){}
10     void notifyTeacherHadFinished(){}
11 }
12 
13 package keyWordsDriver;
14 
15 /**
16  * 
17  */
18 public class MoveDesk {
19 
20     private Person zhangsan;
21 
22 
23     public void setZhangsan(Person zhangsan) {
24         this.zhangsan = zhangsan;
25     }
26 
27     public void setZhangsan() {
28         System.out.println("
");
29         System.out.println("大家好我是张三，你现在执行的方法为：setZhangsan（）");
30         this.zhangsan = new Person();
31         System.out.println("
");
32     }
33 
34     public void moveDeskFromA2B() {
35         zhangsan.getTheCommandFromTeacher();
36         zhangsan.findTheDeskAtA();
37         zhangsan.moveDeskToB();
38         zhangsan.notifyTeacherHadFinished();
39     }
40 }

8.反射需要用的关键字对象整理：

 1 package keyWordsDriver;
 2 
 3 import java.util.HashMap;
 4 import java.util.Map;
 5 
 6 /**
 7  * 1.根据张三 ，得到张三的className，通过className得到张三这个对象，然后再执行张三所要执行的方法（setZhangsan）
 8  */
 9 public class KeywordReflect {
10 
11     public static Map<String, Map<String, String>> KEYWORD_POOLS = new HashMap<String, Map<String, String>>();
12     static{
13         KEYWORD_POOLS.put("张三", KeywordReflect.methodInfo(MoveDesk.class.getName(), "setZhangsan"));
14         KEYWORD_POOLS.put("把桌子从A地点搬到B地点", KeywordReflect.methodInfo(MoveDesk.class.getName(), "moveDeskFromA2B"));
15     }
16 
17     public static Map<String, String> methodInfo(String className, String methodName){
18         Map<String, String> methodInfo = new HashMap<String, String>();
19         methodInfo.put("class", className);
20         methodInfo.put("method", methodName);
21         return methodInfo;
22 
23     }
24 
25   static void  print() {
26        for (Map.Entry<String, Map<String, String>> entrys : KEYWORD_POOLS.entrySet()
27                ) {
28            System.out.println("entrys.getKey()="+entrys.getKey());
29          Map<String,String> values = entrys.getValue();
30            for (Map.Entry<String, String> entyr2 : values.entrySet()
31                    ) {
32                System.out.println(entyr2);
33            }
34        }
35    }
36 
37     public static void main(String[] args) {
38         KeywordReflect.print();
39     }
40 
41 
42 }

9.对象库负责初始化所有需要用到的对象；

 1 package keyWordsDriver;
 2 
 3 import java.util.HashMap;
 4 import java.util.Map;
 5 
 6 /**
 7  * 这是对象的注册中心 ；
 8  */
 9 public class RegisterCenter {
10     public static Map<String, Object> OBJ_POOLS = new HashMap<String, Object>();
11     static{
12         OBJ_POOLS.put(MoveDesk.class.getName(), new MoveDesk());
13     }
14 
15 }

10.解析关键

 1 package keyWordsDriver;
 2 
 3 import java.util.ArrayList;
 4 import java.util.List;
 5 import java.util.regex.Matcher;
 6 import java.util.regex.Pattern;
 7 
 8 /**
 9  * 
10  */
11 public class RegExp {
12     public boolean match(String reg, String str) {
13         return Pattern.matches(reg, str);
14     }
15 
16     public List<String> find(String reg, String str) {
17         Matcher matcher = Pattern.compile(reg).matcher(str);
18         List<String> list = new ArrayList<String>();
19         while (matcher.find()) {
20             list.add(matcher.group());
21         }
22         return list;
23     }
24 
25 }
26 
27 package keyWordsDriver;
28 
29 import java.util.List;
30 
31 /**
32  * ParseKeyword 用于解析关键字，需要指定的格式 ；
33  */
34 public class ParseKeyword {
35     public List<String> getKeywords(String p) {
36         String reg = "(?<=(?<!\\)\$\{)(.*?)(?=(?<!\\)\})";
37         RegExp re = new RegExp();
38         List<String> list = re.find(reg, p);
39         return list;
40 
41     }
42 
43     public static void main(String[] args) {
44 
45         ParseKeyword p = new ParseKeyword();
46         System.out.println(p.getKeywords("${张三}，去${把桌子从A地点搬到B地点}"));
47         System.out.println(p.getKeywords("a${a}a"));
48         System.out.println(p.getKeywords("a\${a}a"));
49         System.out.println(p.getKeywords("a${a\}a"));
50         System.out.println(p.getKeywords("a${a\}a}a"));
51         System.out.println(p.getKeywords("a${a}a${"));
52         System.out.println(p.getKeywords("a${ab}a${a}"));
53 
54     }
55 
56 }

11，方法执行的过程：

  1 package keyWordsDriver;
  2 
  3 import java.io.BufferedReader;
  4 import java.io.File;
  5 import java.io.FileInputStream;
  6 import java.io.InputStreamReader;
  7 import java.lang.reflect.InvocationTargetException;
  8 import java.lang.reflect.Method;
  9 import java.util.ArrayList;
 10 import java.util.List;
 11 import java.util.Map;
 12 
 13 /**
 14  * 利用反射进行方法的执行 ；
 15  */
 16 
 17 public class Executor {
 18     private ParseKeyword pk = new ParseKeyword();
 19 
 20     public List<String> readTxtFile(String filePath) {
 21         List<String> list = new ArrayList<String>();
 22         try {
 23             String encoding = "UTF8";
 24             File file = new File(filePath);
 25             if (file.isFile() && file.exists()) {
 26                 InputStreamReader read = new InputStreamReader(new FileInputStream(file), encoding);
 27                 BufferedReader bufferedReader = new BufferedReader(read);
 28                 String lineTxt = null;

 30                     list.add(lineTxt);
 31                    // System.out.println(" : "+lineTxt);
 32                 }
 33                 read.close();
 34                 bufferedReader.close();
 35             } else {
