彩票计算JAVA版(二)正则分析得到对应数据

彩票计算JAVA版(二)正则分析得到对应数据

正则表达式类RegexUtil.java，默认写了patternStr了，这个参数其实也可以当做参数传递进去
package com.sillycat.easyluck.common.utils;
import java.util.ArrayList;
import java.util.List;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import com.sillycat.easyluck.model.Luck;
public class RegexUtil {
private static final String patternStr = "([0-9]{5}).[0-9]{2}.[0-9]{2}.{3}.([0-9]{2}).([0-9]{2}).([0-9]{2}).([0-9]{2}).([0-9]{2}).([0-9]{2}).{3}([0-9]{2})";

public static List<Luck> getLucksFromString(String contentStr) {
List<Luck> list = new ArrayList<Luck>();
Pattern pattern = Pattern.compile(patternStr);
Matcher matcher = pattern.matcher(contentStr);
boolean result = matcher.find();
int i = 0;
while (result) {
Luck luck = new Luck();
i++;
luck.setCode(matcher.group(1));
List<String> reds = new ArrayList<String>(6);
for (int j = 2; j < matcher.groupCount(); j++) {
reds.add(matcher.group(j));
}
luck.setRedBalls(reds);
luck.setBlueBall(matcher.group((matcher.groupCount())));
list.add(luck);
result = matcher.find();
}
return list;
}
}

存储分析得到的信息的POJO
package com.sillycat.easyluck.model;
import java.util.List;
public class Luck {
private String code;
private List<String> redBalls;
private String blueBall;
... //省略了getter setter
public String toString() {
return new StringBuffer("code:" + code + " red:" + redBalls + " blue:"
+ blueBall).toString();
}

}
单元测试类RegexUtilTest.java类
package com.sillycat.easyluck.common.utils;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.List;
import junit.framework.TestCase;
import com.sillycat.easyluck.common.html.HtmlParserUtil;
import com.sillycat.easyluck.model.Luck;
public class RegexUtilTest extends TestCase {
private static final String contentStr = "...09040期04月09日开奖 04 07 10 20 26 30 + 12.......09042期04月09日开奖 04 07 10 11 13 30 + 12....";
public void testGetLucksFromString() {
List<Luck> list = RegexUtil.getLucksFromString(contentStr);
for (int i = 0; i < list.size(); i++) {
Luck t = list.get(i);
assertNotNull(t);
System.out.println(t);
}
}
}
