MyBatis Application Project 작업순서

Posted 2019. 7. 9. 11:24

java application project에서 테스트를 위한 작업순서(in Maven 프로젝트)

 

1. pom.xml 추가

  1.1 mybatis 기본 dependency 추가 

  <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis -->
	<dependency>
	    <groupId>org.mybatis</groupId>
	    <artifactId>mybatis</artifactId>
	    <version>3.4.1</version>
	</dependency>

 

  1.2 config.xml 설정파일 관련 dependency 추가

<!-- https://mvnrepository.com/artifact/commons-configuration/commons-configuration -->
	<dependency>
	    <groupId>commons-configuration</groupId>
	    <artifactId>commons-configuration</artifactId>
	    <version>1.10</version>
	</dependency>
	
	<!-- https://mvnrepository.com/artifact/commons-collections/commons-collections -->
	<dependency>
	    <groupId>commons-collections</groupId>
	    <artifactId>commons-collections</artifactId>
	    <version>3.2.1</version>
	</dependency>

  1.3 Config.java, ConnectionFactory.java 생성   

-- Config.java --

public class Config {
	private static Configuration configuration;
	 
    static {
        try {
        	URL url = Config.class.getClassLoader().getResource("config/database.xml");
            if (configuration == null) {
				configuration = new XMLConfiguration(url);
            } else {
            	System.out.println("return configuration from Memory...");
            }
        } catch (ConfigurationException e) {
            e.printStackTrace();
        }
    }   
    public static Configuration getConfiguration() {
        return configuration;
    }
}

--  ConnectionFactory.java -----

public class MyBatisConnectionFactory {
	private static SqlSessionFactory sqlSessionFactory;
    static {
        try {
            final String resource = "config/mybatis-config.xml";
            Reader reader = Resources.getResourceAsReader(resource);
            if (sqlSessionFactory == null) {
            	Configuration conf = MyConfig.getConfiguration();    			
    			Properties props = new Properties();    			
    			props.setProperty("driver",	 	conf.getString("jdbc.driver","oracle.jdbc.driver.OracleDriver"));
    			props.setProperty("url", 		conf.getString("jdbc.url","jdbc:oracle:thin:@127.0.0.1:1521:orcl"));
    			props.setProperty("username", 	conf.getString("jdbc.username","test2018"));
    			props.setProperty("password", 	conf.getString("jdbc.password","test2018"));
    			
                sqlSessionFactory = new SqlSessionFactoryBuilder().build(reader, props);
            }
        } catch (FileNotFoundException fileNotFoundException) {
            fileNotFoundException.printStackTrace();
        } catch (IOException iOException) {
            iOException.printStackTrace();
        }
    }
    public static SqlSessionFactory getSqlSessionFactory() {
        return sqlSessionFactory;
    }
}

 

2. TestMain.java 테스트 (Transaction 처리 포함 테스트)

  ...중략...
  
	public static void main(String[] args) {

		SqlSession sqlSession = null;
		try {
			sqlSession = MyBatisConnectionFactory.getSqlSessionFactory().openSession(false);

			//Mapper 사용하는 방법
			TestMapper testMapper = sqlSession.getMapper(TestMapper.class);
			List<Map<String, Object>> progrmList = testMapper.getProgrmList();
			
			//Sqlsession을 사용하는 방법
			List<Map<String, Object>> progrmList = (List<Map<String,Object>>)sqlSession.selectList("getProgrmList");
			
			
			for (Iterator iterator = progrmList.iterator(); iterator.hasNext();) {
				Map<String, Object> map = (Map<String, Object>) iterator.next();
				System.out.println(map);				
			}
			
			Map<String, Object> param = new HashMap<String, Object>();
			param.put("id", "test8");
			param.put("name", "test8 name");
			param.put("age", 88);
			
			testMapper.insertTest(param);
			
			Map<String, Object> param2 = new HashMap<String, Object>();
			param2.put("id", "test5");
			param2.put("name", "test5 update name");
			param2.put("age", 28);
			testMapper.updateTest(param2);
			
			// 커밋
			sqlSession.commit();
		} catch (Exception e) {
			// 롤백
			sqlSession.rollback();
			e.printStackTrace();
		} finally {
			sqlSession.close();
		}
	}
