[7.1.3 Suggester]で使用しているJapaneseReadingFormFilterを参考に。(というかまんま)
今回はeclipseにプラグインを入れてgradleプロジェクトとして作ってみました。
build.gradleはデフォルトで作成されるものにlucene用のdependenciesを追加。
不要なものも混ざってますがご容赦ください。
apply plugin: 'java' apply plugin: 'eclipse' sourceCompatibility = 1.6 targetCompatibility = 1.6 version = '1.0' jar { manifest { attributes 'Implementation-Title': 'Gradle Quickstart', 'Implementation-Version': version } } repositories { mavenCentral() } dependencies { compile 'org.apache.lucene:lucene-core:4.7.2' compile 'org.apache.lucene:lucene-analyzers-common:4.7.2' compile 'org.apache.lucene:lucene-analyzers-kuromoji:4.7.2' testCompile 'junit:junit:4.+' } test { systemProperties 'property': 'value' } uploadArchives { repositories { flatDir { dirs 'repos' } } }
そして、コード
package com.example; import java.io.IOException; import java.util.Arrays; import java.util.List; import org.apache.lucene.analysis.Analyzer; import org.apache.lucene.analysis.TokenStream; import org.apache.lucene.analysis.ja.JapaneseAnalyzer; import org.apache.lucene.analysis.ja.tokenattributes.ReadingAttribute; import org.apache.lucene.analysis.ja.util.ToStringUtil; import org.apache.lucene.analysis.tokenattributes.CharTermAttribute; import org.apache.lucene.util.Version; public class Romanize { public static void main(String[] args) { Analyzer analyzer = new JapaneseAnalyzer(Version.LUCENE_47); try { List<String> texts = Arrays .asList("すもももももももものうち。", "メガネは顔の一部です。", "日本経済新聞でモバゲーの記事を読んだ。", "Java, Scala, Groovy, Clojure", "LUCENE、SOLR、Lucene, Solr", "アイウエオカキクケコさしすせそABCXYZ123456", "Lucene is a full-featured text search engine library written in Java."); for (String text : texts) { TokenStream tokenStream = analyzer.tokenStream("", text); try { romanize(tokenStream); } catch (IOException e) { e.printStackTrace(); } finally { tokenStream.close(); } } } catch (Exception e) { e.printStackTrace(); } finally { analyzer.close(); } } private static void romanize(TokenStream tokenStream) throws IOException { CharTermAttribute charTermAttr = tokenStream .addAttribute(CharTermAttribute.class); ReadingAttribute readingAttr = tokenStream .addAttribute(ReadingAttribute.class); tokenStream.reset(); while (tokenStream.incrementToken()) { String token = charTermAttr.toString(); String reading = readingAttr.getReading(); String readingRoma = null; if (reading != null) { readingRoma = ToStringUtil.getRomanization(reading); } else if (isHalfWidthAlphanumeric(token)) { readingRoma = token; } else { readingRoma = ToStringUtil.getRomanization(token); } System.out.println("token:" + token + " ,reading:" + reading + " ,readingRoma:" + readingRoma); } } private static boolean isHalfWidthAlphanumeric(String text) { if (text == null || text.length() == 0 || text.length() != text.getBytes().length) { return false; } return true; } }
Analyzerの使い方など参考にさせていただいたのはココ
JapaneseAnalyzerでトークン分割後に
String reading = readingAttr.getReading();
読みカナを取得し、
readingRoma = ToStringUtil.getRomanization(reading);
そして読み仮名をToStringUtil.getRomanizationに渡すとローマ字を得られます。
else if (isHalfWidthAlphanumeric(token)) { readingRoma = token; }
半角アルファベットと数字はそのまま使用。
else {
readingRoma = ToStringUtil.getRomanization(token);
}
それ以外の読み仮名が得られなかった単語はとりあえず元の単語をそのままローマ字変換してみましたf^^;
結果は以下となりました。
token:すもも ,reading:スモモ ,readingRoma:sumomo token:もも ,reading:モモ ,readingRoma:momo token:もも ,reading:モモ ,readingRoma:momo token:メガネ ,reading:メガネ ,readingRoma:megane token:顔 ,reading:カオ ,readingRoma:kao token:一部 ,reading:イチブ ,readingRoma:ichibu token:日本 ,reading:ニッポン ,readingRoma:nippon token:日本経済新聞 ,reading:ニホンケイザイシンブン ,readingRoma:nihonkeizaishimbun token:経済 ,reading:ケイザイ ,readingRoma:keizai token:新聞 ,reading:シンブン ,readingRoma:shimbun token:モバゲ ,reading:null ,readingRoma:mobage token:記事 ,reading:キジ ,readingRoma:kiji token:読む ,reading:ヨン ,readingRoma:yon token:java ,reading:null ,readingRoma:java token:scala ,reading:null ,readingRoma:scala token:groovy ,reading:null ,readingRoma:groovy token:clojure ,reading:null ,readingRoma:clojure token:lucene ,reading:null ,readingRoma:lucene token:solr ,reading:null ,readingRoma:solr token:lucene ,reading:null ,readingRoma:lucene token:solr ,reading:null ,readingRoma:solr token:アイウエオカキクケコ ,reading:null ,readingRoma:aiueokakikukeko token:しす ,reading:シス ,readingRoma:shisu token:そ ,reading:ソ ,readingRoma:so token:abcxyz ,reading:null ,readingRoma:abcxyz token:123456 ,reading:null ,readingRoma:123456 token:lucene ,reading:null ,readingRoma:lucene token:is ,reading:null ,readingRoma:is token:a ,reading:null ,readingRoma:a token:full ,reading:null ,readingRoma:full token:featured ,reading:null ,readingRoma:featured token:text ,reading:null ,readingRoma:text token:search ,reading:null ,readingRoma:search token:engine ,reading:null ,readingRoma:engine token:library ,reading:null ,readingRoma:library token:written ,reading:null ,readingRoma:written token:in ,reading:null ,readingRoma:in token:java ,reading:null ,readingRoma:java

MacにJDK6をインストール
職場の環境に合わせるためにJDK6を自宅のmacにインストールしようと思いまして。
早速oracleさんのサイトへ。
Java Archive Downloads - Java SE 6
ファッ!?
教えてgoogle先生!
ってわけで、ありましたよ。
Appleが別途提供しているみたいです。
無事インストール出来ました〜
ただ、デフォルトインストール先がそれぞれで異なるようです。

S2JUnit4をmavenで実行する際の注意点
仕事でJUnitを書いたのは1年目以来でしょうか。(現在8年目。。)
ちょっと時間に余裕ができたので久々に書いてみました。
テスト対象はパラメータで渡した値を条件にDBからレコードを取得するメソッド。
ってことで、↓を参考にExcelでテストデータを用意し自動読み込みするようにして、境界値テストとして取得できるケースとできないケースを計5ケースほど書きました。
Seasar - DI Container with AOP
S2Unit
ローカルでの実行は無事グリーンになり、意気揚々とコミットしてJenkinsさんからテスト環境へビルド/デプロイ&テスト!
・・・
orz..
取得できるケースだけ失敗してるからテストデータが読み込めていない模様。
サンプルのようにテストケースクラスと同フォルダにデータも置いていたんですが、↓のサイトの通りでclasses側にデータがコピーされないせいみたいです。
ってことで、/src/test/resources配下に置き換えて再挑戦したところ、うまくいきました。
ただ、/src/test/resources配下にズラーっと並ぶのが嫌だったので、s2junit4.diconを以下のようにしてテストケースクラス毎にフォルダを分けるようにしました。
<component class="org.seasar.framework.unit.impl.TestDataPreparerImpl"> <initMethod name="addTestDataXlsPath"> <arg> "data/" + context.testClassShortName + "/" + context.testMethodName + ".xls" </arg> </initMethod> <initMethod name="addTestDataXlsPath"> <arg> "data/" + context.testClassShortName + "/common.xls" </arg> </initMethod> </component>
ちなみに現在のカバレッジは0.8%・・レガシーです\(^o^)/
目指せ1%!
eclipse起動エラーの対処法
以下のようなエラーが出た場合、clean起動すると解決するかも? (自分は解決した)

clean起動
/Applications/eclipse/Eclipse.app/Contents/MacOS/eclipse -clean
