ログ出力の設定をしてみる
TweetPosted on Sunday Feb 02, 2014 at 10:43AM in Technology
環境
- PostgreSQL 9.2.4
- OS X 10.9.1
何をするか
- OS XのsyslogをPostgreSQLからのログ出力を受け入れられるように設定する
- PostgreSQLのログをsyslogへ出力するようにする
- 実行されるSQLのログを取ってみる
OS Xのsyslogの設定
/etc/syslog.confを編集する
一番下の行を追加する。こんな感じ。flat file logsは/etc/asl.confに設定されているとか書かれているのでそっちに書いた方がいいのかもしれないけど面倒なのでここで
# Note that flat file logs are now configured in /etc/asl.conf install.* @127.0.0.1:32376 local0.* /var/log/postgresql
設定内容を反映させる
sudo launchctl unload /System/Library/LaunchDaemons/com.apple.syslogd.plist sudo launchctl load /System/Library/LaunchDaemons/com.apple.syslogd.plist
こんなんでもよい
ps -Af | awk '/\/usr\/sbin\/syslogd$/{print "sudo kill -HUP " $2}' | sh
ログを出力してみる
kyle-no-MacBook:etc kyle$ logger -p local0.notice hogehoge kyle-no-MacBook:etc kyle$ ls -l /var/log/postgresql -rw-r--r--@ 1 root wheel 58 2 2 10:55 /var/log/postgresql kyle-no-MacBook:etc kyle$ cat /var/log/postgresql Feb 2 10:55:06 kyle-no-MacBook.local kyle[880]: hogehoge kyle-no-MacBook:etc kyle$
ちゃんと出ていますね。「コンソール」からも内容を見られるのは便利かも
PostgreSQLの設定
$PG_HOME/data/postgresql.confを編集
sudo su postgres -c 'vi /Library/PostgreSQL/9.2/data/postgresql.conf'
以下内容にする
log_destination = 'syslog' syslog_facility = 'LOCAL0' syslog_ident = 'postgres' log_statement = 'all'
一番下がSQLをログに出す設定。大量に出るので要注意
再起動
sudo su postgres -c 'pg_ctl -D /Library/PostgreSQL/9.2/data restart'
ログを見てみる
kyle-no-MacBook:~ kyle$ psql Password: psql (9.2.4) Type "help" for help. kyle=# select now(); now ------------------------------ 2014-02-02 11:32:20.67332+09 (1 row) kyle=# \q kyle-no-MacBook:~ kyle$ cat /var/log/postgresql.log Feb 2 11:20:21 kyle-no-MacBook.local kyle[1002]: hogehogehoge Feb 2 11:31:24 kyle-no-MacBook.local postgres[1073]: [1-1] 2014-02-02 11:31:24 JST LOG: database system was shut down at 2014-02-02 11:31:23 JST Feb 2 11:31:24 kyle-no-MacBook.local postgres[1077]: [1-1] 2014-02-02 11:31:24 JST LOG: autovacuum launcher started Feb 2 11:31:24 kyle-no-MacBook.local postgres[1071]: [1-1] 2014-02-02 11:31:24 JST LOG: database system is ready to accept connections Feb 2 11:31:30 kyle-no-MacBook.local postgres[1083]: [2-1] 2014-02-02 11:31:30 JST LOG: incomplete startup packet Feb 2 11:32:20 kyle-no-MacBook.local postgres[1098]: [2-1] 2014-02-02 11:32:20 JST LOG: statement: select now(); kyle-no-MacBook:~ kyle$
出てますね
その他
できればSQLのログはシビリティをdebugとかにしたいので若干調べた[6]が、よくわからん。現状無理ということだろうか

Just try to use OrderColumn
TweetPosted on Thursday Jan 30, 2014 at 02:09PM in Technology
It sounds convenience so I just tried it.
Environment
- WildFly 8.0.0.Final
- Hibernate 4.3.1
- PostgreSQL 9.2.4
- postgresql-9.3-1100.jdbc41.jar
Does Hibernate require intersection entity for @OrderColumn?
According to [2], it said that @OrderColumn doesn't work with relations like that:
Parent side
@OneToMany(mappedBy = "dept") @OrderColumn(name = "pos") private List<Employee> employees;
Child side
@ManyToOne @JoinColumn(nullable = false) private Dept dept;
I found [1], and it said something like that it working now with recent versions.
And, like said at [2], when I delete mappedBy, it makes intersection entity (dept_employee).

Codes that I will mention later are easy to find in these files:

Conclusion
Pros
- It brings powerful mechanism that developer can reduce some annoying codes to maintain order of the list.
Cons
- It executes bunch of inefficient queries.
- Through considering above queries, maybe use of unique index of order column is impossible.
Remarks
- Not bad for such as low-traffic internal systems.
- To OrderColumn work correctly, we have to keep all elements fetched when modify the list.

Arquillian用ArchiveへクラスとMaven Dependencyを楽に追加する
TweetPosted on Tuesday Jan 28, 2014 at 09:48PM in Technology
環境
- shrinkwrap-resolver 2.1.0-alpha-1
- wildfly-arquillian-container-remote 8.0.0.CR1
- Arquillian 1.1.2.Final
- WildFly 8.0.0.CR1
- Eclipse Kepler SR1
- Oracle JDK7u51
サブパッケージを再帰的に探索させてクラスを追加する
例えばこういう状況で
テストするのに必要なクラス群が複数のパッケージに分散している
クラスの配置
Hige.java
package org.example.hige; import javax.inject.Named; @Named public class Hige { public String hige() { return "hige()"; } }
Hoge.java
package org.example.hoge; import javax.inject.Inject; import javax.inject.Named; import org.example.hige.Hige; @Named public class Hoge { @Inject Hige hige; public String hoge() { return "hoge()" + hige.hige(); } }
こうするとよい
Archive作成時にaddPackages()メソッドをこういう感じで呼んでやればよい。これでいちいち全パッケージに対してaddPackage()呼んでやらずにすむ。第一引数がtrueだと、第二引数で与えたパッケージのサブパッケージを再帰的に探索してくれる。
テストクラス
package org.example.hoge; import javax.inject.Inject; import org.jboss.arquillian.container.test.api.Deployment; import org.jboss.arquillian.junit.Arquillian; import org.jboss.shrinkwrap.api.Archive; import org.jboss.shrinkwrap.api.ShrinkWrap; import org.jboss.shrinkwrap.api.asset.EmptyAsset; import org.jboss.shrinkwrap.api.spec.WebArchive; import org.junit.Assert; import org.junit.Test; import org.junit.runner.RunWith; @RunWith(Arquillian.class) public class HogeTest { @Deployment public static Archive<?> createDeployment() { WebArchive a = ShrinkWrap.create(WebArchive.class, "test.war") .addAsWebInfResource(EmptyAsset.INSTANCE, "beans.xml") .addPackages(true, "org.example"); return a; } @Inject Hoge hoge; @Test public void test() throws Exception { Assert.assertEquals("hoge()hige()", hoge.hoge()); } }
Maven Dependencyを楽に追加する
例えばこういう状況で
guavaをpom.xmlに設定して使っている。Archiveを作る際に、いちいち依存するjarファイルをaddLibraryしていくのが面倒くさい。
Hoge.java
package org.example.hoge; import javax.inject.Named; import com.google.common.collect.Lists; @Named public class Hoge { public void hoge() { Lists.newArrayList(); } }
こうするとよい
pom.xml
shrinkwrap-resolverへの依存を追加する(groupIdがorg.jboss.shrinkwrap.resolverの要素)。例えばこんな感じ
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.example</groupId> <artifactId>arquillian-prac</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <properties> <maven.compiler.source>1.7</maven.compiler.source> <maven.compiler.target>1.7</maven.compiler.target> <failOnMissingWebXml>false</failOnMissingWebXml> </properties> <dependencyManagement> <dependencies> <dependency> <groupId>org.jboss.shrinkwrap.resolver</groupId> <artifactId>shrinkwrap-resolver-bom</artifactId> <version>2.1.0-alpha-1</version> <scope>import</scope> <type>pom</type> </dependency> <dependency> <groupId>org.jboss.arquillian</groupId> <artifactId>arquillian-bom</artifactId> <version>1.1.2.Final</version> <scope>import</scope> <type>pom</type> </dependency> </dependencies> </dependencyManagement> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>2.3.2</version> <configuration> <source>1.7</source> <target>1.7</target> </configuration> </plugin> <plugin> <artifactId>maven-surefire-plugin</artifactId> <version>2.12</version> </plugin> </plugins> </build> <dependencies> <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>7.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <dependency> <groupId>org.mockito</groupId> <artifactId>mockito-all</artifactId> <version>1.9.5</version> <scope>test</scope> </dependency> <dependency> <groupId>org.hamcrest</groupId> <artifactId>hamcrest-integration</artifactId> <version>1.2.1</version> </dependency> <dependency> <groupId>net.avh4.util</groupId> <artifactId>imagecomparison</artifactId> <version>0.0.2</version> <scope>test</scope> </dependency> <dependency> <groupId>org.jboss.arquillian.junit</groupId> <artifactId>arquillian-junit-container</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.wildfly</groupId> <artifactId>wildfly-arquillian-container-remote</artifactId> <version>8.0.0.CR1</version> <scope>test</scope> </dependency> <dependency> <groupId>org.jboss.arquillian.extension</groupId> <artifactId>arquillian-persistence-impl</artifactId> <version>1.0.0.Alpha6</version> <scope>test</scope> </dependency> <dependency> <groupId>org.jboss.shrinkwrap.resolver</groupId> <artifactId>shrinkwrap-resolver-impl-maven</artifactId> <version>2.1.0-alpha-1</version> <scope>test</scope> </dependency> <dependency> <groupId>org.jboss.shrinkwrap.resolver</groupId> <artifactId>shrinkwrap-resolver-api-maven</artifactId> <version>2.1.0-alpha-1</version> <scope>test</scope> </dependency> <dependency> <groupId>com.google.guava</groupId> <artifactId>guava</artifactId> <version>16.0</version> </dependency> </dependencies> </project>
テストクラス
package org.example.hoge; import javax.inject.Inject; import org.jboss.arquillian.container.test.api.Deployment; import org.jboss.arquillian.junit.Arquillian; import org.jboss.shrinkwrap.api.Archive; import org.jboss.shrinkwrap.api.ShrinkWrap; import org.jboss.shrinkwrap.api.asset.EmptyAsset; import org.jboss.shrinkwrap.api.spec.WebArchive; import org.jboss.shrinkwrap.resolver.api.maven.Maven; import org.junit.Assert; import org.junit.Test; import org.junit.runner.RunWith; @RunWith(Arquillian.class) public class HogeTest { @Deployment public static Archive<?> createDeployment() { WebArchive a = ShrinkWrap.create(WebArchive.class, "test.war") .addAsWebInfResource(EmptyAsset.INSTANCE, "beans.xml") .addPackages(true, "org.example"); a.addAsLibraries( Maven.resolver() .loadPomFromFile("pom.xml") .importRuntimeDependencies() .resolve() .withTransitivity() .asFile()); return a; } @Inject Hoge hoge; @Test public void test() throws Exception { hoge.hoge(); Assert.assertTrue(true); } }
importRuntimeDependencies()の他にもいろいろあるので必要に応じて使い分ける。ただ多くなりすぎるとデプロイが遅くなる。
- importRuntimeAndCompileDependencies()
- importDependencies(ScopeType…)
- importRuntimeAndTestDependencies()
- importRuntimeDependencies()
- importTestDependencies()
こういう感じにすると依存性を個別に追加できる[3]
File[] files = Maven.resolver() .loadPomFromFile("pom.xml") .resolve("org.apache.commons:commons-lang3:3.2.1") .withTransitivity() .asFile(); WebArchive w = ShrinkWrap.create(WebArchive.class, "hoge.war").addClass(HogeBean.class) .addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml").addAsLibraries(files);
バージョンの省略も可。省略するとpom.xmlに書いてあるバージョンを取ってきてくれる
File[] files = Maven.resolver() .loadPomFromFile("pom.xml") .resolve("org.apache.commons:commons-lang3") .withTransitivity() .asFile();

orm.xml
以下のようなクエリを追加します
<named-query name="findVariousTypes"> <query><![CDATA[ SELECT v FROM VariousTypes v ]]></query> </named-query>
XlsDataSetTest.java
package org.arquillian.example; import java.math.BigDecimal; import java.util.Calendar; import java.util.Date; import java.util.List; import javax.persistence.EntityManager; import javax.persistence.PersistenceContext; import javax.transaction.Transactional; import org.jboss.arquillian.container.test.api.Deployment; import org.jboss.arquillian.junit.Arquillian; import org.jboss.arquillian.persistence.ShouldMatchDataSet; import org.jboss.arquillian.persistence.UsingDataSet; import org.jboss.shrinkwrap.api.Archive; import org.jboss.shrinkwrap.api.ShrinkWrap; import org.jboss.shrinkwrap.api.asset.EmptyAsset; import org.jboss.shrinkwrap.api.spec.WebArchive; import org.junit.Test; import org.junit.runner.RunWith; @RunWith(Arquillian.class) public class XlsDataSetTest { @Deployment public static Archive<?> createDeployment() { Archive<?> a = ShrinkWrap.create(WebArchive.class, "test.war") .addPackage(VariousTypes.class.getPackage()) .addAsResource("test-persistence.xml", "META-INF/persistence.xml") .addAsResource("META-INF/orm.xml", "META-INF/orm.xml") .addAsWebInfResource(EmptyAsset.INSTANCE, "beans.xml") .addAsWebInfResource("jbossas-ds.xml"); return a; } @PersistenceContext EntityManager em; @Test @Transactional @UsingDataSet("datasets/xlsDataSet/variousTypes.xls") @ShouldMatchDataSet(value = "datasets/xlsDataSet/variousTypesExpected.xls", orderBy = "bigint1") public void select() throws Exception { dumpEntityList(em.createNamedQuery("findVariousTypes", VariousTypes.class).getResultList()); Calendar cal = Calendar.getInstance(); cal.set(2014, 0, 2, 12, 13, 14); cal.set(Calendar.MILLISECOND, 0); Date newDate = cal.getTime(); VariousTypes toModify = em.find(VariousTypes.class, 1l); toModify.setVarchar1("HogeHoge"); toModify.setDate1(newDate); toModify.setTime1(newDate); toModify.setTimestamp1(newDate); toModify.setNumeric1(new BigDecimal("222.2222")); toModify.setDouble1(1.0); dumpEntityList(em.createNamedQuery("findVariousTypes", VariousTypes.class).getResultList()); } protected void dumpEntityList(List<?> list){ for(Object o : list){ System.out.println(o + ", contains=" + em.contains(o)); } } }
variousTypes.xls
今回はMacのExcel2011で作りましたが、.xls形式(.xlsx形式でなく)で出力していれば、LibreOfficeやOpenOfficeで作ってもおそらく問題ありません。日付や時刻は文字列型で入れます。普通に入力するとシリアル値になって正常に認識してくれなくなります。こんな感じ。
blobは少し調べた範囲ではExcel形式では対応してなさそうなのでスルーします。XML形式なら対応しているそうですが試してません[2]
variousTypesExpected.xls
こんな感じ。IDが1のデータをテストクラス内で更新してその結果を検証してみます

更新後のDBも覗いてみたいところですが、コンソールにJPQLから覗いた結果が出ているのでそれでよしとします
備考
- 浮動小数点の検証が気になる。丸め誤差とか。最悪テスト実行後に走らせるSQL文にUPDATEかまして端数を切り捨てるとかすれば出来そうだけど気持ち悪いなあ
- xlsのテストデータ修正後はEclipseでRefreshかけないとなぜか更新後のデータを読んでくれない

ローカルで一人用Gitを使ってみる
TweetPosted on Monday Jan 27, 2014 at 09:45AM in Technology
Eclipseでローカルで一人用Gitを使う方法。初期の操作と日常的な操作。
環境
- Eclipse Kelper SR1
- OS X 10.9.1
JBoss Toolsも入れたせいかもしれないが、どうやら最初からGitプラグイン的なものが入っているようだ。
初回の操作
プロジェクトをGitリポジトリに登録する
たぶん微妙な表現だと思うけど。すでに登録したいプロジェクトが存在するものとする。
プロジェクトを右クリックしてTeam→Share Project
Gitを選んでNext
Createを押す
適当な場所と名前を入れてFinish
入力内容を確認してFinish
結果プロジェクトのアイコンがこんな表示になる
初回コミット
プロジェクトを右クリックしてTeam→Commit
名前とメールアドレスを入れてOK。Githubとか使うと公開されるのかなこれ。とりあえず迷惑メール来ても良さそうなのを入れとく
コミットメッセージと対象資源を選択してCommit。右上のチェックボックスのボタンをクリックすると全ての資源にチェックが入る。何か除外した方が良さそうなものとかも混じってそうな気もするがとりあえずこれで。
結果プロジェクトのアイコンがこんな表示になる。何も資源が入ってないフォルダは?のままだけどこれでいいのかな。
日常的な操作
編集〜差分確認〜コミット
資源を編集して保存するとアイコンがこうなる。「>」 が付く
差分を確認してみる。プロジェクトを右クリックしてCompare With→HEAD Revisionを選択
Git Tree Compare窓に編集された資源が表示されるのでHigeServlet.javaをダブルクリック
差分が表示される
差分を確認したら初回と同じ要領でコミットすると、「>」が消える
ローカルの編集内容を破棄してHEADに戻す
編集した資源を右クリックしてReplace With→HEAD Revisionを選択
OK
履歴を見る
プロジェクトを右クリックしてTeam→Show in Historyを選択
こんな感じに表示される。詳細な情報はこの画面から辿れるようだ
その他
- Macの場合は.DS_Storeをgitに無視させる設定を入れておくとよい[3]。
- Eclipseの設定ファイル群を外したい場合は[4].
