스프링 웹 프로젝트 복습

3/12

오타들과 놓친 설정들로 인해 두시간 동안 삽질을 했다...
스프링은 설정이 참 어렵고 힘들다

pom.xml 수정

테스트를 위한 spring-test
오라클 연동을 위한 spring-jdbc
트랜잭션(아직 배우지 못햇다) spring-tx
dependency를 추가한다.

커넥션 풀을 위한 HikariCP
Mybatis를 이용하기 위해 mybatis, mybatis-spring
데이터베이스에서 데이터를 가져왔을때
콘솔에서 사람이 알아보기 쉽도록 하기 위해
log4jdbc-jog4j2-jdbc4
dependency를 추가한다.

Java 설정을 할 것이기 때문에 web.xml이 없다는 것을 알리고
(failOnMissingWebXml)
마지막으로 junit, javax.servlet-api, spring의 버전을 수정하고
Java 버전을 수정한다.

최종적으로 아래와 같이 작성된다.

Java Configuration

RootConfig 클래스

package org.zerock.config;

import javax.sql.DataSource;

import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.zaxxer.hikari.HikariConfig;
import com.zaxxer.hikari.HikariDataSource;

@Configuration //스프링에게 Configuration이라는 것을 명시
@MapperScan(basePackages= {"org.zerock.mapper"}) //Mapper 을 위한 패키지를 명시
public class RootConfig {
	@Bean
	public DataSource dataSource() {
		HikariConfig hikariConfig = new HikariConfig(); //HikariConfig 객체 생성
		//드라이버 이름, url, 스키마 아이디, 비밀번호를 준다.
		hikariConfig.setDriverClassName("net.sf.log4jdbc.sql.jdbcapi.DriverSpy");
		hikariConfig.setJdbcUrl("jdbc:log4jdbc:oracle:thin:@localhost:1521:XE");
		hikariConfig.setUsername("book_ex");
		hikariConfig.setPassword("book_ex");
		
		HikariDataSource dataSource = new HikariDataSource(hikariConfig);
		//최종 설정을 반환. sqlSessionFactory 메서드에서 호출
		return dataSource;
	}
	
	@Bean
	public SqlSessionFactory sqlSessionFactory() throws Exception {
		SqlSessionFactoryBean sqlSessionFactory = new SqlSessionFactoryBean();
		sqlSessionFactory.setDataSource(dataSource());
		return (SqlSessionFactory) sqlSessionFactory.getObject();
	}
}

ServletConfig 클래스

package org.zerock.config;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.ViewResolverRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;

@EnableWebMvc  //설정이 완료된 여러 스프링 빈을 추가해준다.
@ComponentScan(basePackages = {"org.zerock.controller"}) //컨트롤러가 포함된 패키지 경로 명시
public class ServletConfig implements WebMvcConfigurer{

	@Override
	public void configureViewResolvers(ViewResolverRegistry registry) {
		// 컨트롤러가 View를 통해 화면에 보여줄 때의 설정
		InternalResourceViewResolver bean = new InternalResourceViewResolver();
		bean.setViewClass(JstlView.class);
		bean.setPrefix("/WEB-INF/views/");
		bean.setSuffix(".jsp");
		
		registry.viewResolver(bean);
	}
	
	@Override
	public void addResourceHandlers(ResourceHandlerRegistry registry) {
	
		registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
	}
}

WebConfig 클래스

package org.zerock.config;

import javax.servlet.ServletRegistration;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class WebConfig extends AbstractAnnotationConfigDispatcherServletInitializer{

	@Override
	protected Class<?>[] getRootConfigClasses() {
		// TODO Auto-generated method stub
		return new Class[] {RootConfig.class};
	}

	@Override
	protected Class<?>[] getServletConfigClasses() {
		// TODO Auto-generated method stub
		return new Class[] {ServletConfig.class};
	}

	@Override
	protected String[] getServletMappings() {
		// TODO Auto-generated method stub
		return new String[] {"/"};
	}

	@Override
	protected void customizeRegistration(ServletRegistration.Dynamic registration) {
		// url 경로가 없으면 예외 처리
		registration.setInitParameter("throwExceptionIfNoHandlerFound","true");
	}
	
}

마지막으로 log4jdbc.log4h2.properties 파일을 생성한다.

드디어 전체적인 웹 게시물 관리에 대해 공부할 수 있게 됐다...
