스프링과 스프링부트의 차이점 참고

 

 

와! 스프링부트!

war방식으로 생성해서 실제로 tomcat 서버에 배포했을때 실행이 가능하다.

1) boot 프로젝트 생성

2) pom.xml

라이브러리 추가

	<!-- 외부 레포지토리 추가 -->

3) SpringBoot1Application.java

실행클래스에 인코딩 추가

	@Bean //인코딩
	public HttpMessageConverter<String> responseBConverter(){
		
		return new StringHttpMessageConverter(Charset.forName("UTF-8"));
	}
	//인코딩때문에
	public CharacterEncodingFilter characterEncodingFilter() {
		CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
		characterEncodingFilter.setEncoding("UTF-8");
		characterEncodingFilter.setForceEncoding(true);
		return characterEncodingFilter;
	}

4) application.properties

기본환경 설정

#===server setting
server.port=8888
server.tomcat.uri-encoding=UTF-8

#===view resolver
#spring.mvc.view.prefix=/WEB-INF/views/
#spring.mvc.view.suffix=.jsp

#===dataSource setting
spring.datasource.url=jdbc:oracle:thin:@localhost:1521:XE
spring.datasource.username=jspuser
spring.datasource.password=1234

기본설정

주의) Autowired 자동주입 방속을 사용할때 구현 클래스로 변수를 만들자

        인터페이스로 만들면 구현메서드를 찾지 못하더라..왜?
