MavenとSpringFrameworkを併用する

Maven Spring

新しい職場でMavenとSpringFrameworkを使っているので勉強中です。

Apache Maven 3クックブック Javaソフトウェア開発のための特選レシピ集

Apache Maven 3クックブック Javaソフトウェア開発のための特選レシピ集

Maven3とSpring3を使ってテストを実行するところまでやってみました。

１．プロジェクトを生成する

$ mvn archetype;generate

途中でarchetypeArtifactIdを聞かれるので、maven-archetype-quickstartを選択。
(無選択Enter2回でmaven-archetype-quickstartを選択したことになります)
その他のgroupIdなどは以下のとおりに設定することとします

  • gryoupId : com.example
  • artifactId : example
  • version : 1.0.0
  • package : com.example

２．pom.xmlを編集する

Springを使うために必要な依存アーティファクトは以下を参照しました
Obtaining Spring 3 Artifacts with Maven

    </dependency>
  </dependencies>
</project>

３．context.xmlを作る

src/main/resourcesフォルダを作り、その中にcontext.xmlを作る

<?xml version="1.0" encoding="UTF-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:p="http://www.springframework.org/schema/p"
   xmlns:context="http://www.springframework.org/schema/context"
   xmlns:tx="http://www.springframework.org/schema/tx"
   xsi:schemaLocation="http://www.springframework.org/schema/beans
     http://www.springframework.org/schema/beans/spring-beans.xsd
     http://www.springframework.org/schema/context
     http://www.springframework.org/schema/context/spring-context.xsd
     http://www.springframework.org/schema/tx
     http://www.springframework.org/schema/mvc/spring-tx.xsd">

  <context:component-scan base-package="net.srirangan.packt.maven.services"/>

</beans>

４．サービスクラスを作る

package com.example.services;

import org.springframework.stereotype.Service;

@Service("myServiceOne")
public class MyServiceOne {
  public String getA() {
    return "A";
  }
}

５．テストクラスを作る

package com.example.services;

import static org.junit.Assert.assertEquals;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:context.xml")
public class MyServiceOneTest {

  @Autowired
  private MyServiceOne myServiceOne;

  @Test
  public void shouldGetA() {
    assertEquals("A", myServiceOne.getA());
  }
}

６．テストを実行する

$ mvn test

最終的に以下のような表示が出ればOk
