创建Grails的中文拼音转换服务
实现代码：
package utilityimport net.sourceforge.pinyin4j.PinyinHelperimport net.sourceforge.pinyin4j.format.*class PinyinService { static transactional = falsestatic hanYuPinOutputFormat=nulldef init(){hanYuPinOutputFormat = new HanyuPinyinOutputFormat(); hanYuPinOutputFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE); hanYuPinOutputFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE) hanYuPinOutputFormat.setVCharType(HanyuPinyinVCharType.WITH_V);}//如: convertToList("福州")=["fu", "zhou"] def convertToList(String chinese) {if(hanYuPinOutputFormat==null) init() def pinyin = [] chinese.getChars().each { if(it > 128) { pinyin.add( PinyinHelper.toHanyuPinyinStringArray(it,hanYuPinOutputFormat)[0]) } } return pinyin }//如: convertToString("福州")="FuZhou"def convertToString(String chinese) { if(hanYuPinOutputFormat==null) init() def pinyin = "" chinese.getChars().each { if(it > 128) { pinyin=pinyin+ (PinyinHelper.toHanyuPinyinStringArray(it,hanYuPinOutputFormat)[0]).capitalize() } } return pinyin }//如: convertToAbbreviationString("福州")="FZ"def convertToAbbreviationString(String chinese) { if(hanYuPinOutputFormat==null) init() def pinyin = "" chinese.getChars().each { if(it > 128) { pinyin=pinyin+ PinyinHelper.toHanyuPinyinStringArray(it,hanYuPinOutputFormat)[0][0].capitalize() } } return pinyin }}class BootStrap {def pinyinService def init = { servletContext -> println "Start pinyin testing:" println "中国福州 to list:"+" "+pinyinService.convertToList("中国福州")println "中国福州 to string:"+" "+pinyinService.convertToString("中国福州")println "中国福州 to abbreviation string:"+" "+pinyinService.convertToAbbreviationString("中国福州") println "End pinyin testing." } def destroy = { }}Start pinyin testing:中国福州 to list: [zhong, guo, fu, zhou]中国福州 to string: ZhongGuoFuZhou中国福州 to abbreviation string: ZGFZEnd pinyin testing.
