Show Your ToolBox——锋利的groovy

在工作中使用groovy做了很多辅助工具，这里以代码形式发出来，和喜欢groovy的童鞋们交流下

 

1. 文件操作类

1.1 清除.svn文件夹

import static groovy.io.FileType.*

new File('.').eachFileRecurse(DIRECTORIES, ~/^\.svn$/){
	it.delete()
}

 

 

1.2 在一堆jar中找一个class

 

import java.util.Enumeration
import java.util.zip.ZipEntry
import java.util.zip.ZipFile
import java.util.zip.ZipOutputStream

def findJarFile(File zipFile, String target){
	ZipFile zip = new ZipFile(zipFile)
	ZipEntry entry = null
	Enumeration<? extends ZipEntry> en = zip.entries()
	while (en.hasMoreElements()) {
		entry = en.nextElement()
		if (entry.isDirectory()) {
			continue
		}

		if(entry.name.endsWith(target)){
			println zipFile.name
			println entry
		}
	}
	zip.close()
}

String target = 'TESTMY.class'
new File('D:/lib').eachFile{
	if(it.name.endsWith('.jar'))
		findJarFile(it, target)
}

 

 

1.3 从mvn repository下载一个jar到groovy.conf的path下（）

import groovy.grape.Grape

String dir_lib = System.getProperty('user.home').replaceAll("\\\\", '/') + 
	'/.groovy/lib/'
List mvn = [
	'org.apache.poi', 
	'poi', 
	'3.7'
]
Grape.grab(group:mvn[0], 
	module:mvn[1], version:mvn[2])

String jar_path = System.getProperty('user.home').replaceAll("\\\\", '/') + 
	'/.groovy/grapes/' + mvn[0] + '/' + mvn[1] + '/jars/' + mvn[1] + '-' + mvn[2] + '.jar'

def ant = new AntBuilder()
ant.copy file : jar_path, todir : dir_lib

 

1.4 比较文件夹下的文件不同

String path1 = 'D:/soft/eclipse/plugins/org.apache.ant_1.7.0.v200803061910/lib'

String path2 = 'C:/ANT_HOME/Apache-Ant-1.7.0/lib'

List ll = new File(path1).listFiles().collect{it.name}
List ll2 = new File(path2).listFiles().grep{it.name.endsWith('.jar')}.collect{it.name}

def ant = new AntBuilder()
(ll2 - ll).each{
	ant.copy todir : path1, file : path2 + '/' + it
}

 

1.5 下载一个url到本地文件（爬漫画弄个多线程，很给力的）

 

long begin = System.currentTimeMillis()
String url = 'http://**host.com/***'
new File('output.xml') << new URL(url).text
println System.currentTimeMillis() - begin

 

 

2. 用一些第三方库

2.1 jxl

import jxl.*

String path = "my.xls"
int begin_row = 1
List cols = 'a'..'l'
List ll = []

File file = new File(path)
Workbook wb =  Workbook.getWorkbook(file)
def sheet = wb.sheets[0]

for(i in begin_row..<sheet.rows){
	Map item = [:]
	cols.eachWithIndex{cc, j ->
		Cell cell = sheet.getCell(j, i)
		String content = cell.getContents()
		if(content == null)
			content = ''

		item[cc] = content
	}
	if(item[cols[0]])
		ll << item
}

// excel -> 到一个二位列表了ll，然后你就可以随心所欲了

  2.2 email

import java.security.Security;

import javax.mail.* 

final String POP3Host = '***'
final String userName = 'xx'
final String pwd = 'xxx'

Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider())
def prop = System.getProperties()
prop.setProperty("mail.pop3.socketFactory.class", "javax.net.ssl.SSLSocketFactory")
prop.setProperty("mail.pop3.socketFactory.fallback", "false")
prop.put("mail.pop3.host", POP3Host)
prop.put("mail.imap.starttls.enable", "true")
prop.put("mail.debug", "true")
prop.setProperty("mail.pop3.port ", "995")
prop.setProperty("mail.pop3.socketFactory.port", "995")

def auth = [
	getPasswordAuthentication : {
		new PasswordAuthentication(userName, pwd)
	}
] as Authenticator
def s = Session.getDefaultInstance(prop, auth)
def store = s.getStore("pop3")  
store.connect(POP3Host, userName, pwd) 

Folder folder = store.getFolder("Inbox")  
folder.open(Folder.READ_ONLY) 

FetchProfile profile = new FetchProfile()  
profile.add(FetchProfile.Item.ENVELOPE) 
Message[] arr = folder.getMessages()
folder.fetch(arr, profile) 

println "收件箱的邮件数：" + arr.length  

folder.close(false) 
store.close()

 

2.3 css压缩

def ant = new AntBuilder()

String dir = 'cssjs'

ant.taskdef name: 'yuicompress', 
	classname: 'com.yahoo.platform.yui.compressor.YUICompressTask'

ant.yuicompress linebreak: 300, warn: 'false', munge: 'yes', 
	preserveallsemicolons: 'true', outputfolder: dir, {
		fileset dir: dir, {
			include name: '*.css'
		}
	}

  2.4 执行下fastjson方法

import com.alibaba.fastjson.JSON

import com.alibaba.fastjson.parser.Feature
import com.alibaba.fastjson.serializer.SerializerFeature

List ll = [[test: 'test']]
def sll = [] as SerializerFeature[]
def fll = [] as Feature[]

def bytes = JSON.toJSONBytes(ll, sll)

println JSON.parse(bytes, fll)

  2.5 jftp

import net.sf.jftp.net.* 
import net.sf.jftp.config.Settings

import org.apache.commons.io.IOUtils
   
String host = "xx"
int port = 22
String user = "xx"
String pwd = "xx"

String file = "/xx.txt"

Settings.bufferSize = 16384  
def con = new FtpConnection(host, port, "<default>")
con.setConnectionHandler(new ConnectionHandler()) 
con.login(user, pwd) 
           
InputStream is = con.getDownloadInputStream(file) 
IOUtils.copy(is, new FileOutputStream(new File(file)))

 

3. 文本分析类——这块就用起来比较多了，数据源可以是文本，excel，db，下面只贴一个我最近做的一个分析友盟（umeng.com）自定义事件的一个数据分析的代码（业务场景是ios的一个应用做一个发送、接收的动作，分析下一天中这些动作的错误情况），我贴这段代码没有实际参考价值，只能表明groovy可以做很多很多的事儿

import groovy.sql.Sql

final String format = 'yyyy-MM-dd'
final List versions = ['2.1.9', '2.2.0', 
	'2.2.1', '2.2.2', '2.2.3']
final List datRange = Date.parse(format, '2012-07-07')..Date.parse(format, '2012-07-09')
def pat = /,,,/

// 去掉第一行，取一天的数据和一个版本的数据
def ll = []
new File('umeng').eachFile{ff ->
	ll += ff.readLines()[1..-1]

}

def getLinesTarget = {dat, version ->
	def rll = ll.grep{

	if(dat)

}

def printStat = {lines, version ->

下面一段是根据table ddl(oracle)生成一些项目框架需要的文件（ibatis之类的，abator等工具太不局限了，自己写想怎么生成就怎么生成，顺便推荐大家用用国人的smarty4j，很8错）

 

import xx.Tpl

String dir = './'
String tpl_dir = dir + 'tpl/'

String output_dir = dir + 'output/'
String scriptfile = 'dbscript.sql'
String ns = 'quotation'

File f = new File(dir, scriptfile)

final String begin = 'create table'

4. 一些算法和无聊写的小程序

模拟下双色球中奖的概率

 

def range = 1..33

int len = 7
List his = [
	[num: 10000, result: [3,5,16,18,23,24,15]], 
]

def rand = new Random()

def play = {
	int cc = 0
	List ll = []
	while(1){
		int one = rand.nextInt(range.size()) + 1
		if(one in ll){
		}else{
			ll << one
		}

		if(ll.size() == len && his.any{it.result == ll}){
			def target = his.find{it.result == ll}

			println cc
			println target.num
			println cc / target.num
			println target

			cc = 0
			ll.removeAll()

			break
		}

		if(ll.size() > len){
			ll.removeAll()
		}

		cc++
	}
}

play()

 

附件是一个简单的数字图像识别的程序——很简单的笔画匹配思路，很弱智的，大家也可以看看

 

 

这些是我零零散散找到的最近写过的groovy脚本——很多只是用到了简单的groovy语言的语法和api，不过很有意思而且确实能给自己带来工作的方便，喜欢groovy的童鞋们，一起继续支持啦

 

 

还有就是建议不要使用eclipse和groovy的插件——不给力的，找个简单的文本编辑器，vim/notepad++/editplus之类的，弄个宏运行bat，更快捷些
