NativeQueryでSELECTしてみる

Posted on Saturday Jan 25, 2014 at 11:37PM in Technology

ここではNativeQueryを使うまでもない簡単な単独のエンティティをSELECTしてみます。複雑なのは後々。

環境

  • Hibernate 4.3.0.Final
  • WildFly8.0.0.CR1
  • Oracle JDK7u51
  • postgresql-9.3-1100.jdbc41.jar
  • PostgreSQL 9.2.4

前提条件

関連を持たない単独のエンティティをSELECTしてみる

エンティティクラス等を配置

配置図

図で選択されている資源を作る必要が有ります

Employee.java

package org.arquillian.example;

import java.io.Serializable;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class Employee implements Serializable {

    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    @Column
    private String firstName;
    @Column
    private String lastName;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    @Override
    public String toString() {
        return "Employee [id=" + id + ", firstName=" + firstName + ", lastName=" + lastName + "]";
    }

}

orm.xml

            FROM

            .addPackage(Employee.class.getPackage())
            .addAsResource("test-persistence.xml", "META-INF/persistence.xml")
            .addAsResource("META-INF/orm.xml", "META-INF/orm.xml")

            System.out.println(o + ", contains=" + em.contains(o));
        }
    }
}

employees.yml

employee:

  - id: -2
    firstname: Jiro
    lastname: Suzuki
  - id: -3
    firstname: Saburo

jbossas-ds.xml

ローカルで動いているPostgreSQLにjpapracというDBを作っておきます

            <password>***</password>
        </security>
    </datasource>
</datasources>

test-persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1"
    xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
    <persistence-unit name="test">

        <properties>
            <property name="hibernate.hbm2ddl.auto" value="update" />
            <property name="hibernate.show_sql" value="true" />
        </properties>
    </persistence-unit>
</persistence>

実行結果

コンソールの出力を関係ありそうなところだけ抜粋

10:23:35,245 INFO  [stdout] (pool-2-thread-12) Hibernate: SELECT emp.id, emp.firstName, emp.lastName FROM Employee AS emp
10:23:35,248 INFO  [stdout] (pool-2-thread-12) Employee [id=-1, firstName=Taro, lastName=Yamada], contains=true
10:23:35,248 INFO  [stdout] (pool-2-thread-12) Employee [id=-2, firstName=Jiro, lastName=Suzuki], contains=true
10:23:35,248 INFO  [stdout] (pool-2-thread-12) Employee [id=-3, firstName=Saburo, lastName=Tanaka], contains=true

普通に出てますね。NamedNativeQueryにしてResultSetMappingまで定義するとManagedになる。

備考

@UsingDataSetアノテーションをテストメソッドに付けると、Arquillian Persistence Extensionがデータ投入してくれますが、投入したデータはテスト後にTRUNCATEされてしまうので、テスト後にテーブルで確認しようとしても見えないようです[3]。これを抑制する設定は現状存在しないらしい。まあデバッガか何かで止めれば見られるだろうけど。

arquillian.xmlにこういう内容を書けばTRUNCATEがテスト実行前に走るようになるので、テスト実行後のデータを簡単に確認できます

<?xml version="1.0" encoding="UTF-8"?>
<arquillian xmlns="http://jboss.org/schema/arquillian"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://jboss.org/schema/arquillian
        http://jboss.org/schema/arquillian/arquillian_1_0.xsd">
    <extension qualifier="persistence">
        <property name="defaultCleanupPhase">BEFORE</property>
    </extension>
</arquillian>

HibernateのSQLログは、persistence.xmlのproperties要素内に以下のようなのを追記すると複数行使って見やすくインデントとかしてくれる

<property name="hibernate.format_sql" value="true"/>

ArquillianのテストをリモートのWildFly内でデバッグしてみる

Posted on Saturday Jan 25, 2014 at 10:37PM in Technology

ArquillianをWildFly8.0.0.CR1で動かしてみるの続きです。テストクラスのデバッグをしてみます

ArquillianのRemoteでも普通のクラス同様にデバッグできます[1]。今回のようなケースではEdit Source Lookup Pathをやらないといけないのでその手順を残しておきます

環境

  • wildfly-arquillian-container-remote 8.0.0.CR1
  • Arquillian 1.1.2.Final
  • WildFly 8.0.0.CR1
  • Eclipse Kepler SR1
  • Oracle JDK7u51

前提条件

やってみる

  1. 資源は前述の前提条件の記事で書いたのと全く同じ状態で、テストクラスの39行目にブレークポイントを設定します

  2. WildFlyをDebugで起動します

  3. 右クリック→Run As→JUnit Test。基本的にはこの手順で普通にブレークポイントで止まってデバッグ出来るはず。この手順より後はソースがデバッガに認識されない場合の設定手順です

  4. OK。コンパイラオプションどうのこうの言ってるけど、これONになってても出るし

  5. Yes

  6. Debugパースペクティブに切り替わる。Source not foundと出たら、画面中ほどのEdit Source Lookup Pathをクリック

  7. Addをクリック

  8. Workspace Folderを選択してOK

  9. 作業中のプロジェクトのsrc/test/javaを選択してOK

  10. 追加されたのを確認してOK

  11. ソースと止まってるところが表示されるのを確認

  12. いったんResume(F8)でデバッガを終わらせる

  13. この作業をしている間にデバッガが勝手に終了していたら、投入されたまま放ったらかされているテストデータの掃除などをしておく

  14. 3の手順で再度テストを実行

JavaEE7プロジェクトでArquillianを使ってみる

Posted on Saturday Jan 25, 2014 at 09:23PM in Technology

チュートリアルはJavaEE6ベースで書かれていたが、実際にはJavaEE7で作業したいのでJavaEE7で環境を作る方法

本当はArchetypeを作りたいのだが、まだMavenもEclipseも良くわかっていないのでまた後日

環境

  • WildFly8.0.0.CR1
  • Oracle JDK7u51

手順

  1. WildFly8.0.0CR1でサーブレットを動かしてみるの要領でjavaee7-essentials-archetypeでプロジェクトを作る
  2. java build pathを開き、test用のフォルダが欠けていたりする(test/resourcesとtest/java)のでそれらを作ってRefresh。test用のフォルダはOutput folderをtarget/test-classesに変更する。resourcesフォルダを作ったらExcludedを「**」にする
  3. プロジェクトの設定のdeployment assemblyを開いてテスト用の資源がデプロイされないようにする。test/resourcesがあれば削除
  4. java build pathのorder and exportで並び順を変更
  5. pom.xmlを編集する

pom.xml

こういう感じに改変してやれば良さげ。Arquillian Persistenceも入れておく

</project>

こういう感じのテストが走るようになる

[1]にあったサンプルを少し改変したもの。test-persistence.xmlやjbossas-ds.xmlはArquillianチュートリアルのJPAを使ったテストを走らせるところをやってみるのと同じ。

package org.arquillian.example;

import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

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.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;

@RunWith(Arquillian.class)
public class UserPersistenceTest {

    @Deployment
    public static Archive<?> createDeploymentPackage() {
        return ShrinkWrap.create(WebArchive.class, "test.war")
                .addPackage(UserAccount.class.getPackage())
                .addAsResource("test-persistence.xml", "META-INF/persistence.xml")
                .addAsWebInfResource(EmptyAsset.INSTANCE, "beans.xml")
                .addAsWebInfResource("jbossas-ds.xml");
    }

    @PersistenceContext
    EntityManager em;

    @Test
    @UsingDataSet("datasets/users.yml")
    @ShouldMatchDataSet("datasets/expected-users.yml")
    public void should_change_user_password() throws Exception {
        // given
        String expectedPassword = "LexLuthor";
        UserAccount user = em.find(UserAccount.class, 2L);

        // when
        user.setPassword("LexLuthor");
        user = em.merge(user);

        // then
        Assert.assertEquals(expectedPassword, user.getPassword());
    }
}

テストを走らせると、log4jの設定が無い、slf4jの実装が無い、と怒られるのでそれは適宜対応。

ArquillianをWildFly8.0.0.CR1で動かしてみる

Posted on Saturday Jan 25, 2014 at 05:20PM in Technology

ArquillianチュートリアルのJPAを使ったテストを走らせるところをやってみるの続きです。WildFly8.0.0.CR1に対してremoteモードでArquillianのテストを走らせてみます。

環境

  • WildFly 8.0.0.CR1
  • Eclipse Kepler SR1

Profileの選択を変更

arquillian-wildfly-remoteだけチェックされた状態にしてOK

JVMの設定を変更

このままテストを走らせようとするとUnsupportedClassVersionErrorが出てしまいます。Arquillianを走らせるJREが1.6でWildFlyは1.7なのが原因っぽいのでプロジェクト側のJREを変更します。

  1. プロジェクトの設定→Java Build Path→Librariesを開く

  2. JRE System Library [JavaSE-1.6] を選択してEditを選択

  3. ラジオボタンをAlternate JREに合わせてドロップダウンリストからJava SE 7を選択してOK

  4. JRE System Library [Java SE 7] に変わっているのを確認してOK

テストを走らせる

WildFly8を起動して前回と同じやり方で走らせてみます

GreeterTest (JPA使ってない方)

WARNレベルのメッセージが若干出てますが普通に走ります
